Since ALSA can emulate +the OSS, you don't have to choose any of the OSS/Free modules. Please +enable "OSS API emulation" (CONFIG_SND_OSSEMUL) and both OSS mixer and +PCM supports if you want to run the OSS application with the ALSA. + +When you want to support the WaveTable functionality on some cards +such like SB Live!, you need to enable "Sequencer support" +(CONFIG_SND_SEQUENCER). + +For getting more verbose debug messages, turn on "Verbose printk" and +"Debug" options. For checking the memory leaks, you can turn on +"Debug memory" option, too. "Debug detection" will put more +additional checks for the detection of cards. + +Please note that all the ALSA ISA drivers support Linux isapnp API (if +the card supports). You don't need to configure the PnP via +isapnptools. + + +Module parameters +================= + + A user can modify or set parameters at the load time of the module. If + the module supports more cards and you have got more than one card + of the same type, you may simply specify more values for the parameter, + delimited by commas. + + Note that module option names were changed in 0.9.0rc4. The 'snd_' + prefix was removed. + + Module snd + ---------- + + The module snd is the ALSA core module, which is used by all ALSA + card drivers. This takes the global options for creating devices, + etc. + + major - major # for sound driver + - default is 116 + cards_limit + - specifies card limit # (1-8) + - good for kmod support if you do not want to search + for soundcards which are not installed in your system + device_mode + - specifies permission mask for dynamic sound device filesystem + - default value = 0666 + - for example 'device_mode=0660' + device_gid + - specifies GID number for dynamic sound device filesystem + - default value = 0 (root) + device_uid + - specifies UID number for dynamic sound device filesystem + - default value = 0 (root) + + + Module snd-pcm-oss + ------------------ + + The PCM OSS emulation module. + This module takes the options to change the mapping of devices. + + dsp_map - PCM device number maps assigned to the 1st OSS device. + (default: 0) + adsp_map - PCM device number maps assigned to the 2st OSS device. + (default: 1) + nonblock_open - Don't block opening busy PCM devices. + + For example, when dsp_map=2, /dev/dsp will be mapped to PCM #2 of + the card #0. Similarly, when adsp_map=0, /dev/adsp will be mapped + to PCM #0 of the card #0. + For changing the second or later card, specify the option with + commas, such like "dsp_map=0,1". + + nonblock_open option is used to change the behavior of the PCM + regarding opening the device. When this option is non-zero, + opening a busy OSS PCM device won't be blocked but return + immediately with EAGAIN (just like O_NONBLOCK flag). + + Module snd-rawmidi + ------------------ + + This module takes the options to change the mapping of OSS + devices like snd-pcm-oss module. + + midi_map - MIDI device number maps assigned to the 1st OSS device. + (default: 0) + amidi_map - MIDI device number maps assigned to the 2st OSS device. + (default: 1) + + Global parameters for top soundcard modules + ------------------------------------------- + + Each of top-level soundcard module takes some general options, + + index - 0-7 - index (slot #) for soundcard + - if not set or -1, first free index (slot #) is assigned + id - user identification for card (up to 15 chars) + - default expression is 'card' (for example card1) + - value is used for /proc/asound filesystem + - this value can be used by applications for identification + of card if user does not want identify card with index number + enable - enable card (only first card is enabled by default) + + Module snd-ad1816a + ------------------ + + Module for soundcards based on Analog Devices AD1816A/AD1815 ISA chips. + + port - port # for AD1816A chip (PnP setup) + mpu_port - port # for MPU-401 UART (PnP setup) + fm_port - port # for OPL3 (PnP setup) + irq - IRQ # for AD1816A chip (PnP setup) + mpu_irq - IRQ # for MPU-401 UART (PnP setup) + dma1 - first DMA # for AD1816A chip (PnP setup) + dma2 - second DMA # for AD1816A chip (PnP setup) + + Module supports up to 8 cards, autoprobe and PnP. + + Module snd-ad1848 + ----------------- + + Module for soundcards based on AD1848/AD1847/CS4248 ISA chips. + + port - port # for AD1848 chip + irq - IRQ # for AD1848 chip + dma1 - DMA # for AD1848 chip (0,1,3) + + Module supports up to 8 cards.

Since there are two +DACs, both streams are handled independently unlike the 4/6ch multi- +channel playbacks in the section below. + +As default, ALSA driver assigns the first PCM device (i.e. hw:0,0 for +card#0) for front and 4/6ch playbacks, while the second PCM device +(hw:0,1) is assigned to the second DAC for rear playback. + +There are slight difference between two DACs. + +- The first DAC supports U8 and S16LE formats, while the second DAC + supports only S16LE. +- The seconde DAC supports only two channel stereo. + +Please note that the CM8x38 DAC doesn't support continuous playback +rate but only fixed rates: 5512, 8000, 11025, 16000, 22050, 32000, +44100 and 48000 Hz. + +The rear output can be heard only when "Four Channel Mode" switch is +disabled. Otherwise no signal will be routed to the rear speakers. +As default it's turned on. + +*** WARNING *** +When "Four Channel Mode" switch is off, the output from rear speakers +will be FULL VOLUME regardless of Master and PCM volumes. +This might damage your audio equipment. Please disconnect speakers +before your turn off this switch. +*** WARNING *** + +[ Well.. I once got the output with correct volume (i.e. same with the + front one) and was so excited. It was even with "Four Channel" bit + on and "double DAC" mode. Actually I could hear separate 4 channels + from front and rear speakers! But.. after reboot, all was gone. + It's a very pity that I didn't save the register dump at that + time.. Maybe there is an unknown register to achieve this... ] + +If your card has an extra output jack for the rear output, the rear +playback should be routed there as default. If not, there is a +control switch in the driver "Line-In As Rear", which you can change +via alsamixer or somewhat else. When this switch is on, line-in jack +is used as rear output. + +There are two more controls regarding to the rear output. +The "Exchange DAC" switch is used to exchange front and rear playback +routes, i.e. the 2nd DAC is output from front output. + + +4/6 Multi-Channel Playback +-------------------------- + +The recent CM8738 chips support for the 4/6 multi-channel playback +function. This is useful especially for AC3 decoding. + +When the multi-channel is supported, the driver name has a suffix +"-MC" such like "CMI8738-MC6". You can check this name from +/proc/asound/cards. + +When the 4/6-ch output is enabled, the second DAC accepts up to 6 (or +4) channels. While the dual DAC supports two different rates or +formats, the 4/6-ch playback supports only the same condition for all +channels. Since the multi-channel playback mode uses both DACs, you +cannot operate with full-duplex. + +The 4.0 and 5.1 modes are defined as the pcm "surround40" and "surround51" +in alsa-lib. For example, you can play a WAV file with 6 channels like + + % aplay -Dsurround51 sixchannels.wav + +For programmin the 4/6 channel playback, you need to specify the PCM +channels as you like and set the format S16LE. For example, for playback +with 4 channels, + + snd_pcm_hw_params_set_access(pcm, hw, SND_PCM_ACCESS_RW_INTERLEAVED); + // or mmap if you like + snd_pcm_hw_params_set_format(pcm, hw, SND_PCM_FORMAT_S16_LE); + snd_pcm_hw_params_set_channels(pcm, hw, 4); + +and use the interleaved 4 channel data. + +There are some control switchs affecting to the speaker connections: + +"Line-In As Rear" - As mentioned above, the line-in jack is used + for the rear (3th and 4th channels) output. +"Line-In As Bass" - The line-in jack is used for the bass (5th + and 6th channels) output. +"Mic As Center/LFE" - The mic jack is used for the bass output. + If this switch is on, you cannot use a microphone as a capture + source, of course. + + +Digital I/O +----------- + +The CM8x38 provides the excellent SPDIF capability with very chip +price (yes, that's the reason I bought the card :) + +The SPDIF playback and capture are done via the third PCM device +(hw:0,2). Usually this is assigned to the PCM device "spdif". +The available rates are 44100 and 48000 Hz. +For playback with aplay, you can run like below: + + % aplay -Dhw:0,2 foo.wav + +or + + % aplay -Dspdif foo.wav + +So far, only S16LE format is supported. Still no 24bit. Sorry, not +enough info for this. + +The playback and capture over SPDIF use normal DAC and ADC, +respectively, so you cannot playback both analog and digital streams +simultaneously. + +To enable SPDIF output, you need to turn on "IEC958 Output Switch" +control via mixer or alsactl. Then you'll see the red light on from +the card so you know that's working obviously :) +The SPDIF input is always enabled, so you can hear SPDIF input data +from line-out with "IEC958 In Monitor" switch at any time (see +below). + +You can play via SPDIF even with the first device (hw:0,0), +but SPDIF is enabled only when the proper format (S16LE), sample rate +(441100 or 48000) and channels (2) are used. Otherwise it's turned +off. (Also don't forget to turn on "IEC958 Output Switch", too.) + + +Additionally there are relevant control switches: + +"IEC958 Mix Analog" - Mix analog PCM playback and FM-OPL/3 streams and + output through SPDIF. This switch appears only on old chip + models (CM8738 033 and 037). + Note: without this control you can output PCM to SPDIF. + This is "mixing" of streams, so e.g. it's not for AC3 output + (see the next section). + +"IEC958 In Select" - Select SPDIF input, the internal CD-in (false) + and the external input (true). + +"IEC958 Loop" - SPDIF input data is loop back into SPDIF + output (aka bypass) + +"IEC958 Copyright" - Set the copyright bit. + +"IEC958 5V" - Select 0.5V (coax) or 5V (optical) interface. + On some cards this doesn't work and you need to change the + configuration with hardware dip-switch. + +"IEC958 In Monitor" - SPDIF input is routed to DAC. + +"IEC958 In Phase Inverse" - Set SPDIF input format as inverse. + [FIXME: this doesn't work on all chips..] + +"IEC958 In Valid" - Set input validity flag detection. + +Note: When "PCM Playback Switch" is on, you'll hear the digital output +stream through analog line-out. + + +The AC3 (RAW DIGITAL) OUTPUT +---------------------------- + +The driver supports raw digital (typically AC3) i/o over SPDIF. This +can be toggled via IEC958 playback control, but usually you need to +access it via alsa-lib. See alsa-lib documents for more details. + +On the raw digital mode, the "PCM Playback Switch" is automatically +turned off so that non-audio data is heard from the analog line-out. +Similarly the following switches are off: "IEC958 Mix Analog" and +"IEC958 Loop". The switches are resumed after closing the SPDIF PCM +device automatically to the previous state. + +On the model 033, AC3 is implemented by the software conversion in +the driver. This prevents the mmap support. If you need mmap +support, pass the "soft_ac3=0" module option. This doesn't matter +on the newer models. + + +ANALOG MIXER INTERFACE +---------------------- + +The mixer interface on CM8x38 is similar to SB16. +There are Master, PCM, Synth, CD, Line, Mic and PC Speaker playback +volumes. Synth, CD, Line and Mic have playback and capture switches, +too, as well as SB16. + +In addition to the standard SB mixer, CM8x38 provides more functions. +- PCM playback switch +- PCM capture switch (to capture the data sent to DAC) +- Mic Boost switch +- Mic capture volume +- Aux playback volume/switch and capture switch +- 3D control switch + + +MIDI CONTROLLER +--------------- + +The MPU401-UART interface is enabled as default only for the first +(CMIPCI) card. You need to set module option "midi_port" properly +for the 2nd (CMIPCI) card. + +There is _no_ hardware wavetable function on this chip (except for +OPL3 synth below). +What's said as MIDI synth on Windows is a software synthesizer +emulation. On Linux use TiMidity or other softsynth program for +playing MIDI music. + + +FM OPL/3 Synth +-------------- + +The FM OPL/3 is also enabled as default only for the first card. +Set "fm_port" module option for more cards. + +The output quality of FM OPL/3 is, however, very weird. +I don't know why.. + + +Joystick and Modem +------------------ + +The joystick and modem should be available by enabling the control +switch "Joystick" and "Modem" respectively. But I myself have never +tested them yet. + + +Debugging Information +--------------------- + +The registers are shown in /proc/asound/cardX/cmipci. If you have any +problem (especially unexpected behavior of mixer), please attach the +output of this proc file together with the bug report. diff -urN linux-2.4.21-rc1.orig/Documentation/ALSA/ControlNames.txt linux/Documentation/ALSA/ControlNames.txt --- linux-2.4.21-rc1.orig/Documentation/ALSA/ControlNames.txt 1969-12-31 17:00:00.000000000 -0700 +++ linux/Documentation/ALSA/ControlNames.txt 2003-02-28 09:50:19.000000000 -0700 @@ -0,0 +1,84 @@ +This document describes standard names of mixer controls. + +Syntax: SOURCE [DIRECTION] FUNCTION + +DIRECTION: + (both directions) + Playback + Capture + Bypass Playback + Bypass Capture + +FUNCTION: + Switch (on/off switch) + Volume + Route (route control, hardware specific) + +SOURCE: + Master + Master Mono + Hardware Master + Headphone + PC Speaker + Phone + Phone Input + Phone Output + Synth + FM + Mic + Line + CD + Video + Zoom Video + Aux + PCM + PCM Front + PCM Rear + PCM Pan + Loopback + Analog Loopback (D/A -> A/D loopback) + Digital Loopback (playback -> capture loopback - without analog path) + Mono + Mono Output + Multi + ADC + Wave + Music + I2S + IEC958 + +Exceptions: + [Digital] Capture Source + [Digital] Capture Switch (aka input gain switch) + [Digital] Capture Volume (aka input gain volume) + [Digital] Playback Switch (aka output gain switch) + [Digital] Playback Volume (aka output gain volume) + Tone Control - Switch + Tone Control - Bass + Tone Control - Treble + 3D Control - Switch + 3D Control - Center + 3D Control - Depth + 3D Control - Wide + 3D Control - Space + 3D Control - Level + Mic Boost [(?dB)] + +PCM interface: + + Sample Clock Source { "Word", "Internal", "AutoSync" } + Clock Sync Status { "Lock", "Sync", "No Lock" } + External Rate /* external capture rate */ + Capture Rate /* capture rate taken from external source */ + +IEC958 (S/PDIF) interface: + + IEC958 [...] [Playback|Capture] Switch /* turn on/off the IEC958 interface */ + IEC958 [...] [Playback|Capture] Volume /* digital volume control */ + IEC958 [...] [Playback|Capture] Default /* default or global value - read/write */ + IEC958 [...] [Playback|Capture] Mask /* consumer and professional mask */ + IEC958 [...] [Playback|Capture] Con Mask /* consumer mask */ + IEC958 [...] [Playback|Capture] Pro Mask /* professional mask */ + IEC958 [...] [Playback|Capture] PCM Stream /* the settings assigned to a PCM stream */ + IEC958 Q-subcode [Playback|Capture] Default /* Q-subcode bits */ + IEC958 Preamble [Playback|Capture] Default /* burst preamble words (4*16bits) */ diff -urN linux-2.4.21-rc1.orig/Documentation/ALSA/DocBook/alsa-driver-api.tmpl linux/Documentation/ALSA/DocBook/alsa-driver-api.tmpl --- linux-2.4.21-rc1.orig/Documentation/ALSA/DocBook/alsa-driver-api.tmpl 1969-12-31 17:00:00.000000000 -0700 +++ linux/Documentation/ALSA/DocBook/alsa-driver-api.tmpl 2003-02-28 09:03:58.000000000 -0700 @@ -0,0 +1,101 @@ + + + + + + + + + + The ALSA Driver API + + + + This document is free; you can redistribute it and/or modify it + under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + + + This document is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the + implied warranty of MERCHANTABILITY or FITNESS FOR A + PARTICULAR PURPOSE.

The document focuses mainly on the PCI soundcard. + In the case of other device types, the API might + be different, too. However, at least the ALSA kernel API is + consistent, and therefore it would be still a bit help for + writing them. + + + + The target of this document is ones who already have enough + skill of C language and have the basic knowledge of linux + kernel programming. This document doesn't explain the general + topics of linux kernel codes and doesn't cover the detail of + implementation of each low-level driver. It describes only how is + the standard way to write a PCI sound driver on ALSA. + + + + If you are already familiar with the older ALSA ver.0.5.x, you + can check the drivers such as es1938.c or + maestro3.c which have also almost the same + code-base in the ALSA 0.5.x tree, so you can compare the differences. + + + + This document is still a draft version. Any feedbacks and + corrections, please!! + + + + + + + + + File Tree Structure + +
+ General + + The ALSA drivers are provided in the two ways. + + + + One is the the trees provided as a tarball or via cvs from the + ALSA's ftp site, and another is the 2.5 (or later) Linux kernel + tree. To synchronize both, the ALSA driver tree is split to + two different trees: alsa-kernel and alsa-driver. The former + contains purely the source codes for the Linux 2.5 (or later) + tree. This tree is designed only for compilation on 2.5 or + later environment. The latter, alsa-driver, contains many subtle + files for compiling the ALSA driver on the outside of Linux + kernel like configure script, the wrapper functions for older, + 2.2 and 2.4 kernels, to adapt the latest kernel API, + and additional drivers which are still in development or in + tests. The drivers in alsa-driver tree will be moved to + alsa-kernel (eventually 2.5 kernel tree) once when they are + finished and confirmed to work fine. + + + + The file tree structure of ALSA driver is depicted below. Both + alsa-kernel and alsa-driver have almost the same file + structure, except for core directory. It's + named as acore in alsa-driver tree. + + + ALSA File Tree Structure + + sound + /core + /oss + /seq + /oss + /instr + /ioctl32 + /include + /drivers + /mpu401 + /opl3 + /i2c + /l3 + /synth + /emux + /pci + /(cards) + /isa + /(cards) + /arm + /ppc + /sparc + /usb + /pcmcia /(cards) + /oss + + + +
+ +
+ core directory + + This directory contains the middle layer, that is, the heart + of ALSA drivers. In this directory, the native ALSA modules are + stored. The sub-directories contain different modules and are + dependent upon the kernel config. + + +
+ core/oss + + + The codes for PCM and mixer OSS emulation modules are stored + in this directory. The rawmidi OSS emulation is included in + the ALSA rawmidi code since it's quite small. The sequencer + code is stored in core/seq/oss directory (see + + below). + +
+ +
+ core/ioctl32 + + + This directory contains the 32bit-ioctl wrappers for 64bit + architectures such like x86-64, ppc64 and sparc64. For 32bit + and alpha architectures, these are not compiled. + +
+ +
+ core/seq + + This and its sub-directories are for the ALSA + sequencer. This directory contains the sequencer core and + primary sequencer modules such like snd-seq-midi, + snd-seq-virmidi, etc. They are compiled only when + CONFIG_SND_SEQUENCER is set in the kernel + config. + +
+ +
+ core/seq/oss + + This contains the OSS sequencer emulation codes. + +
+ +
+ core/seq/instr + + This directory contains the modules for the sequencer + instrument layer. + +
+
+ +
+ include directory + + This is the place for the public header files of ALSA drivers, + which are to be exported to the user-space, or included by + several files at different directories. Basically, the private + header files should not be placed in this directory, but you may + still find files there, due to historical reason :) + +
+ +
+ drivers directory + + This directory contains the non-architecture-specific + codes. For example, the dummy pcm driver and the serial MIDI + driver are found in this directory. In the sub-directories, + there are the codes for components which are independent from + bus and cpu architectures. + + +
+ drivers/mpu401 + + The MPU401 and MPU401-UART modules are stored here. + +
+ +
+ drivers/opl3 + + The OPL3 FM-synth stuff is found here. + +
+
+ +
+ i2c directory + + This contains the ALSA i2c components. + + + + Although there is a standard i2c layer on Linux, ALSA uses its + own i2c codes for some cards, because the soundcard needs only a + simple operation and the standard API is too complicated for + such a purpose. + + +
+ i2c/l3 + + This is a sub-directory for ARM L3 i2c. + +
+
+ +
+ synth directory + + This contains the synth middle-level modules. + + + + So far, there is only Emu8000/Emu10k1 synth driver under + synth/emux sub-directory. + +
+ +
+ pci directory + + This and its sub-directories hold the top-level card modules + for PCI soundcards. + + + + The drivers compiled from a single file is stored directly on + pci directory, while the drivers with several source files are + stored on its own sub-directory (e.g. emu10k1, ice1712). + +
+ +
+ isa directory + + This and its sub-directories hold the top-level card modules + for ISA soundcards. + +
+ +
+ arm, ppc, and sparc directories + + These are for the top-level card modules which are + architecture specific. + +
+ +
+ usb directory + + This contains the USB-audio driver. On the latest version, the + USB MIDI driver is integrated together with usb-audio driver. + +
+ +
+ pcmcia directory + + The PCMCIA, especially PCCard drivers will go here. CardBus + drivers will be on pci directory, because its API is identical + with the standard PCI cards. + + + + At this moment, only VX-pocket driver exists. + +
+ +
+ oss directory + + The OSS/Lite source files are stored here on Linux 2.5 (or + later) tree. (In the ALSA driver tarball, it's empty, of course :) + +
+ + + + + + + + Basic Flow for PCI Drivers + +
+ Outline + + The minimum flow of PCI soundcard is like the following: + + + define the PCI ID table (see the section + PCI Entries + ). + create probe() callback. + create remove() callback. + create pci_driver table which contains the three pointers above. + create init() function just calling pci_module_init() to register the pci_driver table defined above. + create exit() function to call pci_unregister_driver() function. + + +
+ +
+ Full Code Example + + The code example is shown below. Some parts are kept + unimplemented at this moment but will be filled in the + succeeding sections. The numbers in comment lines of + snd_mychip_probe() function are the + markers. + + + Basic Flow for PCI Drivers Example + + + #include + #include + #include + #include + #define SNDRV_GET_ID + #include + + // module parameters (see "Module Parameters") + static int index[SNDRV_CARDS] = SNDRV_DEFAULT_IDX; + static char *id[SNDRV_CARDS] = SNDRV_DEFAULT_STR; + static int enable[SNDRV_CARDS] = SNDRV_DEFAULT_ENABLE_PNP; + + // definition of the chip-specific record + typedef struct snd_mychip mychip_t; + struct snd_mychip { + snd_card_t *card; + // rest of implementation will be in the section + // "PCI Resource Managements" + }; + + // this should be go into + // (see "Management of Cards and Components") + #define mychip_t_magic 0xa15a4501 + + // chip-specific destructor + // (see "PCI Resource Managements") + static int snd_mychip_free(mychip_t *chip) + { + // will be implemented later... + } + + // component-destructor + // (see "Management of Cards and Components") + static int snd_mychip_dev_free(snd_device_t *device) + { + mychip_t *chip = snd_magic_cast(mychip_t, + device->device_data, return -ENXIO); + return snd_mychip_free(chip); + } + + // chip-specific constructor + // (see "Management of Cards and Components") + static int __devinit snd_mychip_create(snd_card_t *card, + struct pci_device *pci, + mychip_t **rchip) + { + mychip_t *chip; + int err; + static snd_device_ops_t ops = { + .dev_free = snd_mychip_dev_free, + }; + + *rchip = NULL; + + // check PCI availability here + // (see "PCI Resource Managements") + + // allocate a chip-specific data with magic-alloc + chip = snd_magic_kcalloc(mychip_t, 0, GFP_KERNEL); + if (chip == NULL) + return -ENOMEM; + + chip->card = card; + + // rest of initialization here; will be implemented + // later, see "PCI Resource Managements" + + if ((err = snd_device_new(card, SNDRV_DEV_LOWLEVEL, + chip, &ops)) < 0) { + snd_mychip_free(chip); + return err; + } + *rchip = chip; + return 0; + } + + // constructor -- see "Constructor" sub-section + static int __devinit snd_mychip_probe(struct pci_dev *pci, + const struct pci_device_id *pci_id) + { + static int dev; + snd_card_t *card; + mychip_t *chip; + int err; + + // (1) + if (dev >= SNDRV_CARDS) + return -ENODEV; + if (!enable[dev]) { + dev++; + return -ENOENT; + } + + // (2) + card = snd_card_new(index[dev], id[dev], THIS_MODULE, 0); + if (card == NULL) + return -ENOMEM; + + // (3) + if ((err = snd_mychip_create(card, pci, &chip)) < 0) { + snd_card_free(card); + return err; + } + + // (4) + // implemented later + + // (5) + strcpy(card->driver, "My Chip"); + strcpy(card->shortname, "My Own Chip 123"); + sprintf(card->longname, "%s at 0x%lx irq %i", + card->shortname, chip->ioport, chip->irq); + + // (6) + if ((err = snd_card_register(card)) < 0) { + snd_card_free(card); + return err; + } + + // (7) + pci_set_drvdata(pci, chip); + dev++; + return 0; + } + + // destructor -- see "Destructor" sub-section + static void __devexit snd_mychip_remove(struct pci_dev *pci) + { + mychip_t *chip = snd_magic_cast(mychip_t, + pci_get_drvdata(pci), return); + if (chip) + snd_card_free(chip->card); + pci_set_drvdata(pci, NULL); + } +]]> + + + +
+ +
+ Constructor + + The real constructor of PCI drivers is probe callback. The + probe callback and other component-constructors which are called + from probe callback should be defined with + __devinit prefix. You + cannot use __init prefix for them, + because any PCI device could be a hotplug device. + + + + In the probe callback, the following scheme is often used. + + +
+ 1) Check and increment the device index. + + + += SNDRV_CARDS) + return -ENODEV; + if (!enable[dev]) { + dev++; + return -ENOENT; + } +]]> + + + + where enable[dev] is the module option. + + + + At each time probe callback is called, check the + availability of the device. If not available, simply increment + the device index and returns. dev will be incremented also + later (step + 7). + +
+ +
+ 2) Create a card instance + + + + + + + + + + The detail will be explained in the section + + Management of Cards and Components. + +
+ +
+ 3) Create a main component + + In this part, the PCI resources are allocated. + + + + + + + + The detail will be explained in the section PCI Resource + Managements. + +
+ +
+ 4) Create other components, such as mixer, MIDI, etc. + + Here you define the basic components such as + PCM, + mixer (e.g. AC97), + MIDI (e.g. MPU-401), + and other interfaces. + Also, if you want a proc + file, define it here, too. + +
+ +
+ 5) Set the driver ID and name strings. + + + +driver, "My Chip"); + strcpy(card->shortname, "My Own Chip 123"); + sprintf(card->longname, "%s at 0x%lx irq %i", + card->shortname, chip->ioport, chip->irq); +]]> + + + + The driver field holds the minimal ID string of the + chip. This is referred by alsa-lib's configurator, so keep it + simple but unique. + Even the same driver can have different driver IDs to + distinguish the functionality of each chip type. + + + + The shortname field is a string shown as more verbose + name. The longname field contains the information which is + shown in /proc/asound/cards. + +
+ +
+ 6) Register the card instance. + + + + + + + + + + Will be explained in the section Management + of Cards and Components, too. + +
+ +
+ 7) Set the PCI driver data and return zero. + + + + + + + + In the above, the chip record is stored. This pointer is + referred in the remove callback and power-management + callbacks, too. + If the card doesn't support the suspend/resume, you can store + the card pointer instead of the chip pointer, so that + snd_card_free can be called directly + without cast in the remove callback. But anyway, be sure + which pointer is used. + +
+
+ +
+ Destructor + + The destructor, remove callback, simply releases the card + instance. Then the ALSA middle layer will release all the + attached components automatically. + + + + It would be typically like the following: + + + +card); + pci_set_drvdata(pci, NULL); + } +]]> + + + + The above code assumes that the chip is allocated + with snd_magic stuff and + has the field to hold the card pointer (see the next + section). + +
+ +
+ Header Files + + For the above example, at least the following include files + are necessary. + + + + + #include + #include + #include + #include + #define SNDRV_GET_ID + #include +]]> + + + + where the last twos are necessary only when module options are + defined in the source file. If the codes are split to several + files, the file without module options don't need them. + + + + In addition to them, you'll need + <linux/interrupt.h> for the interrupt + handling, and <asm/io.h> for the i/o + access. If you use mdelay() or + udelay() functions, you'll need to include + <linux/delay.h>, too. + + + + The ALSA interfaces like PCM or control API are define in other + header files as <sound/xxx.h>. + They have to be included after + <sound/core.h>. + + +
+ + + + + + + + Management of Cards and Components + +
+ Card Instance + + For each soundcard, a card record must be allocated. + + + + A card record is the headquarters of the soundcard. It manages + the list of whole devices (components) on the soundcard, such as + PCM, mixers, MIDI, synthesizer, and so on. Also, the card + record holds the ID and the name strings of the card, manages + the root of proc files, and controls the power-management states + and hotplug disconnections. The component list on the card + record is used to manage the proper releases of resources at + destruction. + + + + As mentioned above, to create a card instance, call + snd_card_new(). + + + + + + + + + + The function takes four arguments, the card-index number, the + id string, the module pointer (usually + THIS_MODULE), + and the size of extra-data space. The last argument is used to + allocate card->private_data for the + chip-specific data. Note that this data + is allocated by + snd_card_new(). + +
+ +
+ Components + + After the card is created, you can attach the components + (devices) to the card instance. On ALSA driver, a component is + represented as a snd_device_t object. + A component can be a PCM instance, a control interface, a raw + MIDI interface, etc. Each of such instances has one component + entry. + + + + A component can be created via + snd_device_new() function. + + + + + + + + + + This takes the card pointer, the device-level + (SNDRV_DEV_XXX), the data pointer, and the + callback pointers (&ops). The + device-level defines the type of components and the order of + registration and de-registration. For most of components, the + device-level is already defined. For a user-defined component, + you can use SNDRV_DEV_LOWLEVEL. + + + + This function itself doesn't allocate the data space. The data + must be allocated manually beforehand, and its pointer is passed + as the argument. This pointer is used as the identifier + (chip in the above example) for the + instance. + + + + Each ALSA pre-defined component such as ac97 or pcm calls + snd_device_new() inside its + constructor. The destructor for each component is defined in the + callback pointers. Hence, you don't need to take care of + calling a destructor for such a component. + + + + If you would like to create your own component, you need to + set the destructor function to dev_free callback in + ops, so that it can be released + automatically via snd_card_free(). The + example will be shown later as an implementation of a + chip-specific data. + +
+ +
+ Chip-Specific Data + + The chip-specific information, e.g. the i/o port address, its + resource pointer, or the irq number, is stored in the + chip-specific record. + Usually, the chip-specific record is typedef'ed as + xxx_t like the following: + + + + + + + + + + You might have objections against such a typedef, but this + typedef is necessary if you use a magic-cast + (explained later). + + + + In general, there are two ways to allocate the chip record. + + +
+ 1. Allocating via <function>snd_card_new()</function>. + + As mentioned above, you can pass the extra-data-length to the 4th argument of snd_card_new(), i.e. + + + + + + + + whether mychip_t is the type of the chip record. + + + + In return, the allocated record can be accessed as + + + +private_data; +]]> + + + + With this method, you don't have to allocate twice. But you + cannot use magic-cast for this record pointer, + instead. + +
+ +
+ 2. Allocating an extra device. + + + After allocating a card instance via + snd_card_new() (with + NULL on the 4th arg), call + snd_magic_kcalloc(). + + + + + + + + Once when the record is allocated via snd_magic stuff, you + can use magic-cast for the void pointer. + + + + The chip record should have the field to hold the card + pointer at least, + + + + + + + + + + Then, set the card pointer in the returned chip instance. + + + +card = card; +]]> + + + + + + Also, you need to define a magic-value for mychip_t. + + + + + + + (the detail will be described in the + + next subsection). + + + + Next, initialize the fields, and register this chip + record as a low-level device with a specified + ops, + + + + + + + + snd_mychip_dev_free() is the + device-destructor function, which will call the real + destructor. + + + + + +device_data, + return -ENXIO); + return snd_mychip_free(chip); + } +]]> + + + + where snd_mychip_free() is the real destructor. + +
+ +
+ Not a magic but a logic + + Now, you might have a question: What is the advantage of the + second method? Obviously, it looks far more complicated. + + As I wrote many times, the second method allows a + magic-cast for mychip_t. If you + have a void pointer (such as + pcm->private_data), the pointer type + is unknown at the compile time, and you cannot know even if a + wrong pointer type is passed. The compiler would accept + it. The magic-cast checks the pointer type at the runtime (and + whether it's a null pointer, too). Hence, the cast will be + much safer and good for debugging. + + + + As you have already seen, allocation with a magic-header can + be done via snd_magic_kmalloc() or + snd_magic_kcalloc(). + + + + + + + + The difference of these two functions is whether the area is + zero-cleared (kcalloc) or not + (kmalloc). + + + + The first argument of the allocator is the type of the + record. The magic-constant has to be defined for this type + beforehand. In this case, we'll need to define + mychip_t_magic, for example, as already + seen, + + + + + + + + The value is arbitrary but should be unique. + This is usually defined in + <include/sndmagic.h> or + <include/amagic.h> for alsa-driver tree, + but you may define it locally in the code at the early + development stage, since changing + sndmagic.h will lead to the recompilation + of the whole driver codes. + + + + The second argument is the extra-data length. It is usually + zero. The third argument is the flags to be passed to kernel + memory allocator, GFP_XXX. Normally, + GFP_KERNEL is passed. + + + + For casting a pointer, use + snd_magic_cast() macro: + + + + + + + + where source_pointer is the pointer to + be casted (e.g. pcm->private_data), and + action is the action to do if the cast + fails (e.g. return -EINVAL). + + + + For releasing the magic-allocated data, you need to call + snd_magic_kfree() function instead of + kfree(). + + + + + + + + + + If you call kfree() for the + magic-allocated value, it will lead to memory leaks. + When the ALSA drivers are compiled with + CONFIG_SND_DEBUG_MEMORY kernel config (or + configured with ), the + non-matching free will be checked and you'll see warning + messages. + + + + If you are 100% sure that your code is bug-free, you can + compile the driver without + CONFIG_SND_DEBUG_MEMORY kernel config, + so that the magic-allocator and the magic-cast will be + replaced to the normal kmalloc and cast. + +
+
+ +
+ Registration and Release + + After all components are assigned, register the card instance + by calling snd_card_register(). The access + to the device files are enabled at this point. That is, before + snd_card_register() is called, the + components are safely inaccessible from external side. If this + call fails, exit the probe function after releasing the card via + snd_card_free(). + + + + For releasing the card instance, you can call simply + snd_card_free(). As already mentioned, all + components are released automatically by this call. + + + + As further notes, the destructors (both + snd_mychip_dev_free and + snd_mychip_free) cannot be defined with + __devexit prefix, because they may be + called from the constructor, too, at the false path. + + + + For a device which allows hotplugging, you can use + snd_card_free_in_thread. This one will + postpone the destruction and wait in a kernel-thread until all + devices are closed. + + +

+ +
+ Some Hafta's + + The allocation of PCI resources is done in the + probe() function, and usually an extra + xxx_create() function is written for this + purpose. + + + + In the case of PCI devices, you have to call at first + pci_enable_device() function before + allocating resources. Also, you need to set the proper PCI DMA + mask to limit the accessed i/o range. In some cases, you might + need to call pci_set_master() function, + too. + + + + Suppose the 28bit mask, and the code to be added would be like: + + + + + + + +
+ +
+ Resource Allocation + + The allocation of ports and irqs are done via standard kernel + functions. Unlike ALSA ver.0.5.x., there are no helpers for + that. And these resources must be released in the destructor + function (see below). Also, on ALSA 0.9.x, you don't need + allocate (pseudo-)DMA for PCI like 0.5.x. + + + + Now assume that this PCI device has an I/O port with 8 bytes + and an interrupt. Then mychip_t will have the + following fields: + + + + + + + + + + For an i/o port (and also a memory region), you need to have + the resource pointer for the standard resource management. For + an irq, you have to keep only the irq number (integer). But you + need to initialize this number as -1 before actual allocation, + since irq 0 is valid. The port address and its resource pointer + can be initialized as null by + snd_magic_kcalloc() automatically, so you + don't have to take care of it. + + + + The allocation of an i/o port is done like this: + + + +port = pci_resource_start(pci, 0); + if ((chip->res_port = request_region(chip->port, 8, + "My Chip")) == NULL) { + printk(KERN_ERR "cannot allocate the port 0x%lx\n", + chip->port); + snd_mychip_free(chip); + return -EBUSY; + } +]]> + + + + + + It will reserve the i/o port region of 8 bytes of the given + PCI device. The returned value, chip->res_port, is allocated + via kmalloc() by + request_region(). The pointer must be + released via kfree(), but there is some + problem regarding this. This issue will be explained more below. + + + + The allocation of an interrupt source is done like this: + + + +irq, snd_mychip_interrupt, + SA_INTERRUPT|SA_SHIRQ, "My Chip", + (void *)chip)) { + snd_mychip_free(chip); + printk(KERN_ERR "cannot grab irq %d\n", pci->irq); + return -EBUSY; + } + chip->irq = pci->irq; +]]> + + + + where snd_mychip_interrupt() is the + interrupt handler defined later. + Note that chip->irq should be defined + only when request_irq() succeeded. + + + + On the PCI bus, the interrupts can be shared. Thus, + SA_SHIRQ is given as the interrupt flag of + request_irq(). + + + + The last argument of request_irq() is the + data pointer passed to the interrupt handler. Usually, the + chip-specific record is used for that, but you can use what you + like, too. + + + + I won't define the detail of the interrupt handler at this + point, but at least its appearance can be explained now. The + interrupt handler looks usually like the following: + + + + + + + + Again the magic-cast is used here to get the correct pointer + from the second argument. + + + + Now let's write the corresponding destructor for the resources + above. The role of destructor is simple: disable the hardware + (if already activated) and release the resources. So far, we + have no hardware part, so the disabling is not written here. + + + + For releasing the resources, check-and-release + method is a safer way. For the i/o port, do like this: + + + +res_port) { + release_resource(chip->res_port); + kfree_nocheck(chip->res_port); + } +]]> + + + + + + As you can see, the i/o resource pointer is also to be freed + via kfree_nocheck() after + release_resource() is called. You + cannot use kfree() here, because on ALSA, + kfree() may be a wrapper to its own + allocator with the memory debugging. Since the resource pointer + is allocated externally outside the ALSA, it must be released + via the native + kfree(). + kfree_nocheck() is used for that; it calls + the native kfree() without wrapper. + + + + For releasing the interrupt, do like this: + + + +irq >= 0) + free_irq(chip->irq, (void *)chip); +]]> + + + + And finally, release the chip-specific record. + + + + + + + + + + The chip instance is freed via + snd_magic_kfree(). Please use this function + for the object allocated by + snd_magic_kmalloc(). If you free it with + kfree(), it won't work properly and will + result in the memory leak. Also, again, remember that you cannot + set __devexit prefix for this destructor. + + + + We didn't implement the hardware-disabling part in the above. + If you need to do this, please note that the destructor may be + called even before the initialization of the chip is completed. + It would be better to have a flag to skip the hardware-disabling + if the hardware was not initialized yet. + + + + When the chip-data is assigned to the card using + snd_device_new() with + SNDRV_DEV_LOWLELVEL , its destructor is + called at the last. that is, it is assured that all other + components like PCMs and controls have been already released. + You don't have to call stopping PCMs, etc. explicitly, but just + stop the hardware in the low-level. + + + + The management of a memory-mapped region is almost as same as + the management of an i/o port. You'll need three fields like + the following: + + + + + + + + and the allocation would be (assuming its size is 512 bytes): + + + +iobase_phys = pci_resource_start(pci, 0); + chip->iobase_virt = (unsigned long) + ioremap_nocache(chip->iobase_phys, 512); + if ((chip->res_port = request_mem_region(chip->iobase_phys, 512, + "My Chip")) == NULL) { + printk(KERN_ERR "cannot allocate the memory region\n"); + snd_mychip_free(chip); + return -EBUSY; + } +]]> + + + + and the corresponding destructor would be: + + + +iobase_virt) + iounmap((void *)chip->iobase_virt); + if (chip->res_iobase) { + release_resource(chip->res_iobase); + kfree_nocheck(chip->res_iobase); + } + .... + } +]]> + + + + +
+ +
+ PCI Entries + + So far, so good. Let's finish the rest of missing PCI + stuffs. At first, we need a + pci_device_id table for this + chipset. It's a table of PCI vendor/device ID number, and some + masks. + + + + For example, + + + + + + + + + + The first and second fields of + pci_device_id struct are the vendor and + device IDs. If you have nothing special to filter the matching + devices, you can use the rest of fields like above. The last + field of pci_device_id struct is a + private data for this entry. You can specify any value here, for + example, to tell the type of different operations per each + device IDs. Such an example is found in intel8x0 driver. + + + + The last entry of this list is the terminator. You must + specify this all-zero entry. + + + + Then, prepare the pci_driver record: + + + + + + + + + + The probe and + remove functions are what we already + defined in + the previous sections. The remove should + be defined with + __devexit_p() macro, so that it's not + defined for built-in (and non-hot-pluggable) case. The + name + field is the name string of this device. Note that you must not + use a slash / in this string. + + + + And at last, the module entries: + + + + + + + + + + Note that these module entries are tagged with + __init and + __exit prefixes, not + __devinit nor + __devexit. + + + + Oh, one thing was forgotten. If you have no exported symbols, + you need to declare it on 2.2 or 2.4 kernels (on 2.5 kernels + it's not necessary, though). + + + + + + + + That's all! + +
+ + + + + + + + PCM Interface + +
+ General + + The PCM middle layer of ALSA is quite powerful and it is only + necessary for each driver to implement the low-level functions + to access its hardware. + + + + For accessing to the PCM layer, you need to include + <sound/pcm.h> above all. In addition, + <sound/pcm_params.h> might be needed + if you access to some functions related with hw_param. + + + + Each card device can have up to four pcm instances. A pcm + instance corresponds to a pcm device file. The limitation of + number of instances comes only from the available bit size of + the linux's device number. Once when 64bit device number is + used, we'll have more available pcm instances. + + + + A pcm instance consists of pcm playback and capture streams, + and each pcm stream consists of one or more pcm substreams. Some + soundcard supports the multiple-playback function. For example, + emu10k1 has a PCM playback of 32 stereo substreams. In this case, at + each open, a free substream is (usually) automatically chosen + and opened. Meanwhile, when only one substream exists and it was + already opened, the succeeding open will result in the blocking + or the error with EAGAIN according to the + file open mode. But you don't have to know the detail in your + driver. The PCM middle layer will take all such jobs. + +
+ +

The first argument is the card pointer to which this + pcm is assigned, and the second is the ID string. + + + + The third argument (index, 0 in the + above) is the index of this new pcm. It begins from zero. When + you will create more than one pcm instances, specify the + different numbers in this argument. For example, + index = 1 for the second PCM device. + + + + The fourth and fifth arguments are the number of substreams + for playback and capture, respectively. Here both 1 are given in + the above example. When no playback or no capture is available, + pass 0 to the corresponding argument. + + + + If a chip supports multiple playbacks or captures, you can + specify more numbers, but they must be handled properly in + open/close, etc. callbacks. When you need to know which + substream you are referring to, then it can be obtained from + snd_pcm_substream_t data passed to each callback + as follows: + + + +number; +]]> + + + + + + After the pcm is created, you need to set operators for each + pcm stream. + + + + + + + + + + The operators are defined typically like this: + + + + + + + + Each of callbacks is explained in the subsection + + Operators. + + + + After setting the operators, most likely you'd like to + pre-allocate the buffer. For the pre-allocation, simply call + the following: + + + +pci, pcm, + 64*1024, 64*1024); +]]> + + + + It will allocate up to 64kB buffer as default. The details of + buffer management will be described in the later section Buffer and Memory + Management. + + + + Additionally, you can set some extra information for this pcm + in pcm->info_flags. + The available values are defined as + SNDRV_PCM_INFO_XXX in + <sound/asound.h>, which is used for + the hardware definition (described later). When your soundchip + supports only half-duplex, specify like this: + + + +info_flags = SNDRV_PCM_INFO_HALF_DUPLEX; +]]> + + + +
+ +
+ ... And the Destructor? + + The destructor for a pcm instance is not always + necessary. Since the pcm device will be released by the middle + layer code automatically, you don't have to call destructor + explicitly. + + + + The destructor would be necessary when you created some + special records internally and need to release them. In such a + case, set the destructor function to + pcm->private_free: + + + PCM Instance with a Destructor + +private_data, return); + // free your own data + kfree(chip->my_private_pcm_data); + // do what you like else... + } + + static int __devinit snd_mychip_new_pcm(mychip_t *chip) + { + snd_pcm_t *pcm; + .... + // allocate your own data + chip->my_private_pcm_data = kmalloc(...); + // set the destructor + pcm->private_data = chip; + pcm->private_free = mychip_pcm_free; + .... + } +]]> + + + +
+ +
+ Operators + + OK, now let me explain the detail of each pcm callback + (ops). In general, every callback must + return 0 if successful, or a negative number with the error + number such as -EINVAL at any + error. + + + + The callback function takes at least the argument with + snd_pcm_substream_t pointer. For retrieving the + chip record from the given substream instance, you can use the + following macro. + + + + + + + + + + It's expanded with a magic-cast, so the cast-error is + automatically checked. You should define chip_t at + the beginning of the code, since this will be referred in many + places of pcm and control interfaces. + + +
+ open callback + + + + + + + + This is called when a pcm substream is opened. + + + + At least, here you have to initialize the runtime hardware + record. Typically, this is done by like this: + + + +runtime; + + runtime->hw = snd_mychip_playback_hw; + return 0; + } +]]> + + + + where snd_mychip_playback_hw is the + pre-defined hardware record. + + + + + + + + + + The similar struct exists on ALSA 0.5.x driver, so you can + guess the values if you already wrote a driver. + + + + The info field contains the type and + capabilities of this pcm. The bit flags are defined in + <sound/asound.h> as + SNDRV_PCM_INFO_XXX. Here, at least, you + have to specify whether the mmap is supported and which + interleaved format is supported. + When the mmap is supported, add + SNDRV_PCM_INFO_MMAP flag here. When the + hardware supports the interleaved or the non-interleaved + format, SNDRV_PCM_INFO_INTERLEAVED or + SNDRV_PCM_INFO_NONINTERLEAVED flag must + be set, respectively. If both are supported, you can set both, + too. + + + + In the above example, MMAP_VALID and + BLOCK_TRANSFER are specified for OSS mmap + mode. Usually both are set. Of course, + MMAP_VALID is set only if the mmap is + really supported. + + + + The other possible flags are + SNDRV_PCM_INFO_PAUSE and + SNDRV_PCM_INFO_RESUME. The + PAUSE bit means that the pcm supports the + pause operation, while the + RESUME bit means that the pcm supports + the suspend/resume operation. If these flags + are set, the trigger callback below + must handle the corresponding commands. + + + + formats field contains the bit-flags + of supported formats (SNDRV_PCM_FMTBIT_XXX). + If the hardware supports more than one format, give all or'ed + bits. In the example above, the signed 16bit little-endian + format is specified. + + + + rates field contains the bit-flags of + supported rates (SNDRV_PCM_RATE_XXX). + When the chip supports continuous rates, pass + CONTINUOUS bit additionally. + The pre-defined rate bits are only for typical rates. If your + chip supports unconventional rates, you need to add + KNOT bit and set up the + constraint manually (explained later). + + + + There have been many changes of terminology between + ALSA 0.5.x and 0.9.x. + On the ALSA 0.9.x world, period means what is + known as fragment in the OSS. It's the least + size of (a part of) the buffer to generate an interrupt. + + + + Now, taking the new terminology into account, the other fields + are self-explanatory (I hope). Please note that here, both + min/max buffer and period sizes are specified in bytes. + + + + Some drivers allocate the private instance for each pcm + substream. It can be stored in + substream->runtime->private_data. + Since it's a void pointer, you + should use magic-kmalloc and magic-cast for such an object. + + + +runtime->private_data = data; + .... + } +]]> + + + + + + The allocated object must be released in the close callback below. + +
+ +
+ close callback + + + + + + + + Obviously, this is called when a pcm substream is closed. + + + + Any private instance for a pcm substream allocated in the + open callback will be released here. + + + +runtime->private_data); + .... + } +]]> + + + +
+ +
+ ioctl callback + + This is used for any special action to pcm ioctls. But + usually you can pass a generic ioctl callback, + snd_pcm_lib_ioctl. + +
+ +
+ hw_params callback + + + + + + + + This and hw_free callbacks exist + only on ALSA 0.9.x. + + + + This is called when the hardware parameter + (hw_params) is set + up by the application, + that is, once when the buffer size, the period size, the + format, etc. are defined for the pcm substream. + + + + Many hardware set-up should be done in this callback, + including the allocation of buffers. + + + + Parameters to be initialized are retrieved by + params_xxx() macros. For allocating a + buffer, you can call a helper function, + + + + + + + + snd_pcm_lib_malloc_pages() is available + only when the DMA buffers have been pre-allocated. + See the section + Buffer Types for more details. + + + + Note that this and prepare callbacks + may be called multiple times per initialization. + For example, the OSS emulation may + call these callbacks at each change via its ioctl. + + + + Thus, you need to take care not to allocate the same buffers + many times, which will lead to memory leak! Calling the + helper function above many times is OK. It will release the + previous buffer automatically when it was already allocated. + + + + Another note is that this callback is non-atomic + (schedulable). This is important, because the + prepare callback + is atomic (non-schedulable). That is, mutex or any + schedule-related functions are available only in + hw_params callback. + Please see the subsection + + Atomicity for details. + +
+ +
+ hw_free callback + + + + + + + + + + This is called to release the resources allocated via + hw_params. For example, releasing the + buffer via + snd_pcm_lib_malloc_pages() is done by + calling the following: + + + + + + + + + + This callback may be called multiple times, too. + Keep track whether the resource was already released. + +
+ +
+ prepare callback + + + + + + + + + + This callback is called when the pcm is + prepared. You can set the format type, sample + rate, etc. here. The difference from + hw_params is that the + prepare callback will be called at each + time + snd_pcm_prepare() is called, i.e. when + recovered after underruns, etc. + + + + As mentioned above, this callback is atomic. + + + + In this and the following callbacks, you can refer to the + values via the runtime record, + substream->runtime. + For example, to get the current + rate, format or channels, access to + runtime->rate, + runtime->format or + runtime->channels, respectively. + The physical address of the allocated buffer is set to + runtime->dma_area. The buffer and period sizes are + in runtime->buffer_size and runtime->period_size, + respectively. + + + + Note that the period and the buffer sizes are stored in + frames. In the ALSA world, 1 frame = channels + * samples-size. For conversion between frames and bytes, you + can use the helper functions, + frames_to_bytes() and + bytes_to_frames(). + + + +period_size); +]]> + + + + + + Be careful that this callback will be called many times at + each set up, too. + +
+ +
+ trigger callback + + + + + + + + This is called when the pcm is started, stopped or paused. + + + + Which action is specified in the second argument, + SNDRV_PCM_TRIGGER_XXX in + <sound/pcm.h>. At least, + START and STOP + commands must be defined in this callback. + + + + + + + + + + When the pcm supports the pause operation (given in info + field of the hardware table), PAUSE_PUSE + and PAUSE_RELEASE commands must be + handled here, too. The former is the command to pause the pcm, + and the latter to restart the pcm again. + + + + When the pcm supports the suspend/resume operation, + SUSPEND and RESUME + commands must be handled, too. Obviously it does suspend and + resume of the pcm substream. Usually, the + SUSPEND is identical with + STOP command and the + RESUME is identical with + START command. + + + + This callback is also atomic. + +
+ +
+ pointer callback + + + + + + + + This callback is called when the PCM middle layer inquires + the current hardware position on the buffer. The position must + be returned in frames (which was in bytes on ALSA 0.5.x), + ranged from 0 to buffer_size - 1. + + + + This is called usually from the buffer-update routine in the + pcm middle layer, which is invoked when + snd_pcm_period_elapsed() is called in the + interrupt routine. Then the pcm middle layer updates the + position and calculates the available space, and wakes up the + sleeping poll threads, etc. + + + + This callback is also atomic. + +
+ +
+ copy and silence callbacks + + These callbacks are not mandatory, and can be omitted in + most cases. These callbacks are used when the hardware buffer + cannot be on the normal memory space. Some chips have their + own buffer on the hardware which is not mappable. In such a + case, you have to transfer the data manually from the memory + buffer to the hardware buffer. Or, if the buffer is + non-contiguous on both physical and virtual memory spaces, + these callbacks must be defined, too. + + + + If these two callbacks are defined, copy and set-silence + operations are done by them. The detailed will be described in + the later section Buffer and Memory + Management. + +
+ +
+ ack callback + + This callback is also not mandatory. This callback is called + when the appl_ptr is updated in read or write operations. + Some drivers like emu10k1-fx and cs46xx need to track the + current appl_ptr for the internal buffer, and this callback + is useful only for such a purpose. + +
+ +
+ page callback + + + This callback is also not mandatory. This callback is used + mainly for the non-contiguous buffer. The mmap calls this + callback to get the page address. Some examples will be + explained in the later section Buffer and Memory + Management, too. + +
+
+ +
+ Interrupt Handler + + The rest of pcm stuff is the PCM interrupt handler. The + role of PCM interrupt handler in the sound driver is to update + the buffer position and to tell the PCM middle layer when the + buffer position goes across the prescribed period size. To + inform this, call snd_pcm_period_elapsed() + function. + + + + There are several types of sound chips to generate the interrupts. + + +
+ Interrupts at the period (fragment) boundary + + This is the most frequently found type: the hardware + generates an interrupt at each period boundary. + In this case, you can call + snd_pcm_period_elapsed() at each + interrupt. + + + + snd_pcm_period_elapsed() takes the + substream pointer as its argument. Thus, you need to keep the + substream pointer accessible from the chip instance. For + example, define substream field in the chip record to hold the + current running substream pointer, and set the pointer value + at open callback (and reset at close callback). + + + + If you aquire a spinlock in the interrupt handler, and the + lock is used in other pcm callbacks, too, then you have to + release the lock before calling + snd_pcm_period_elapsed(), because + snd_pcm_period_elapsed() calls other pcm + callbacks inside. + + + + A typical coding would be like: + + + Interrupt Handler Case #1 + +lock); + .... + if (pcm_irq_invoked(chip)) { + // call updater, unlock before it + spin_unlock(&chip->lock); + snd_pcm_period_elapsed(chip->substream); + spin_lock(&chip->lock); + } + .... + spin_unlock(&chip->lock); + } +]]> + + + +
+ +
+ High-frequent timer interrupts + + This is the case when the hardware doesn't generate interrupts + at the period boundary but do timer-interrupts at the fixed + timer rate (e.g. es1968 or ymfpci drivers). + In this case, you need to check the current hardware + position and accumulates the processed sample length at each + interrupt. When the accumulated size overcomes the period + size, call + snd_pcm_period_elapsed() and reset the + accumulator. + + + + A typical coding would be like the following. + + + Interrupt Handler Case #2 + +lock); + .... + if (pcm_irq_invoked(chip)) { + unsigned int last_ptr, size; + // get the current hardware pointer (in frames) + last_ptr = get_hw_ptr(chip); + // calculate the processed frames since the + // last update + if (last_ptr < chip->last_ptr) + size = runtime->buffer_size + last_ptr + - chip->last_ptr; + else + size = last_ptr - chip->last_ptr; + // remember the last updated point + chip->last_ptr = last_ptr; + // accumulate the size + chip->size += size; + // over the period boundary? + if (chip->size >= runtime->period_size) { + // reset the accumulator + chip->size %= runtime->period_size; + // call updater + spin_unlock(&chip->lock); + snd_pcm_period_elapsed(substream); + spin_lock(&chip->lock); + } + } + .... + spin_unlock(&chip->lock); + } +]]> + + + +
+ +
+ On calling <function>snd_pcm_period_elapsed()</function> + + In both cases, even if more than one period are elapsed, you + don't have to call + snd_pcm_period_elapsed() many times. Call + only once. And the pcm layer will check the current hardware + pointer and update to the latest status. + +
+
+ +
+ Atomicity + + One of the most important (and thus difficult to debug) problem + on the kernel programming is the race condition. + On linux kernel, usually it's solved via spin-locks or + semaphores. In general, if the race condition may + happen in the interrupt handler, it's handled as atomic, and you + have to use spinlock for protecting the critical session. If it + never happens in the interrupt and it may take relatively long + time, you should use semaphore. + + + + As already seen, some pcm callbacks are atomic and some are + not. For example, hw_params callback is + non-atomic, while prepare callback is + atomic. This means, the latter is called already in a spinlock + held by the PCM middle layer. Please take this atomicity into + account when you use a spinlock or a semaphore in the callbacks. + + + + In the atomic callbacks, you cannot use functions which may call + schedule or go to + sleep. The semaphore and mutex do sleep, + and hence they cannot be used inside the atomic callbacks + (e.g. prepare callback). + For taking a certain delay in such a callback, please use + udelay() or mdelay(). + + + + This atomicity problem appears also in the initialization of the + hardware when the power-management is supported. The functions + for suspending and resuming the chip must be atomic, i.e. no + mutex nor sleep can be used in them. + + +
+
+ Constraints + + If your chip supports unconventional sample rates, or only the + limited samples, you need to set a constraint for the + condition. + + + + For example, in order to restrict the sample rates in the some + supported values, use + snd_pcm_hw_constraint_list(). + You need to call this function in the open callback. + + + Example of Hardware Constraints + +runtime, 0, + SNDRV_PCM_HW_PARAM_RATE, + &constraints_rates); + if (err < 0) + return err; + .... + } +]]> + + + + + + There are many different constraints. You can even define your + own constraint rules. I won't explain the details here, rather I + would like to say, Luke, use the source. + +
+ + + + + + + + + Control Interface + +
+ General + + The control interface is used widely for many switches, + sliders, etc. which are accessed from the user-space. Its most + important use is the mixer interface. In other words, on ALSA + 0.9.x, all the mixer stuff is implemented on the control kernel + API (while there was an independent mixer kernel API on 0.5.x). + + + + ALSA has a well-defined AC97 control module. If your chip + supports only the AC97 and nothing else, you can skip this + section. + + + + The control API is defined in + <sound/control.h>. + Include this file if you add your own controls. + +
+ +
+ Definition of Controls + + For creating a new control, you need to define the three + callbacks: info, + get and + put. Then, define a + snd_kcontrol_new_t record, such as: + + + Definition of a Control + + + + + + + + Most likely the control is created via + snd_ctl_new1(), and in such a case, you can + add __devinitdata prefix to the + definition like above. + + + + The iface field specifies the type of + the control, + SNDRV_CTL_ELEM_IFACE_XXX. There are + MIXER, PCM, + CARD, etc. + + + + The name is the name identifier + string. On ALSA 0.9.x, the control name is very important, + because its role is classified from its name. There are + pre-defined standard control names. The details are described in + the subsection + + Control Names. + + + + The index field holds the index number + of this control. If there are several different controls with + the same name, they can be distinguished by the index + number. This is the case when + several codecs exist on the card. If the index is zero, you can + omit the definition above. + + + + The access field contains the access + type of this control. Give the combination of bit masks, + SNDRV_CTL_ELEM_ACCESS_XXX, there. + The detailed will be explained in the subsection + + Access Flags. + + + + The private_values field contains + an arbitrary long integer value for this record. When using + generic info, + get and + put callbacks, you can pass a value + through this field. If several small numbers are necessary, you can + combine them in bitwise. Or, it's possible to give a pointer + (casted to unsigned long) of some record to this field, too. + + + + The other three are + + callback functions. + +
+ +
+ Control Names + + There are some standards for defining the control names. A + control is usually defined from the three parts as + SOURCE DIRECTION FUNCTION. + + + + The first, SOURCE, specifies the source + of the control, and is a string such as Master, + PCM, CD or + Line. There are many pre-defined sources. + + + + The second, DIRECTION, is one of the + following strings according to the direction of the control: + Playback, Capture, Bypass + Playback and Bypass Capture. Or, it can + be omitted, meaning both playback and capture directions. + + + + The third, FUNCTION, is one of the + following strings according to the function of the control: + Switch, Volume and + Route. + + + + The example of control names are, thus, Master Capture + Switch or PCM Playback Volume. + + + + There are some exceptions: + + +
+ Global capture and playback + + Capture Source, Capture Switch + and Capture Volume are used for the global + capture (input) source, switch and volume. Similarly, + Playback Switch and Playback + Volume are used for the global output gain switch and + volume. + +
+ +
+ Tone-controls + + tone-control switch and volumes are specified like + Tone Control - XXX, e.g. Tone Control - + Switch, Tone Control - Bass, + Tone Control - Center. + +
+ +
+ 3D controls + + 3D-control switches and volumes are specified like 3D + Control - XXX, e.g. 3D Control - + Switch, 3D Control - Center, 3D + Control - Space. + +
+ +
+ Mic boost + + Mic-boost switch is set as Mic Boost or + Mic Boost (6dB). + + + + More precise information can be found in + alsa-kernel/Documentation/ControlNames.txt. + +
+
+ +
+ Access Flags + + + The access flag is the bit-flags which specifies the access type + of the given control. The default access type is + SNDRV_CTL_ELEM_ACCESS_READWRITE, + which means both read and write are allowed to this control. + When the access flag is omitted (i.e. = 0), it is + regarded as READWRITE access as default. + + + + When the control is read-only, pass + SNDRV_CTL_ELEM_ACCESS_READ instead. + In this case, you don't have to define + put callback. + Similarly, when the control is write-only (although it's a rare + case), you can use WRITE flag instead, and + you don't need get callback. + + + + If the control value changes frequently (e.g. the VU meter), + VOLATILE flag should be given. This means + that the control may be changed without + + notification. Applications should poll such + a control constantly. + + + + When the control is inactive, set + INACTIVE flag, too. + There are LOCK and + OWNER flags for changing the write + permissions. + + +
+ +
+ Callbacks + +
+ info callback + + The info callback is used to get + the detailed information of this control. This must store the + values of the given snd_ctl_elem_info_t + object. For example, for a boolean control with a single + element will be: + + + Example of info callback + +type = SNDRV_CTL_ELEM_TYPE_BOOLEAN; + uinfo->count = 1; + uinfo->value.integer.min = 0; + uinfo->value.integer.max = 1; + return 0; + } +]]> + + + + + + The type field specifies the type + of the control. There are BOOLEAN, + INTEGER, ENUMERATED, + BYTES, IEC958 and + INTEGER64. The + count field specifies the + number of elements in this control. For example, a stereo + volume would have count = 2. The + value field is a union, and + the values stored are depending on the type. The boolean and + integer are identical. + + + + The enumerated type is a bit different from others. You'll + need to set the string for the currently given item index. + + + +value.enumerated.items = 4; + if (uinfo->value.enumerated.item > 3) + uinfo->value.enumerated.item = 3; + strcpy(uinfo->value.enumerated.name, + texts[uinfo->value.enumerated.item]); +]]> + + + +
+ +
+ get callback + + + This callback is used to read the current value of the + control and to return to the user-space. + + + + For example, + + + Example of get callback + +value.integer.value[0] = get_some_value(chip); + return 0; + } +]]> + + + + + + Here, the chip instance is retrieved via + snd_kcontrol_chip() macro. This macro + converts from kcontrol->private_data to the type defined by + chip_t. The + kcontrol->private_data field is + given as the argument of snd_ctl_new() + (see the later subsection + Constructor). + + + + The value field is depending on + the type of control as well as on info callback. For example, + the sb driver uses this field to store the register offset, + the bit-shift and the bit-mask. The + private_value is set like + + + + + + and is retrieved in callbacks like + + +private_value & 0xff; + int shift = (kcontrol->private_value >> 16) & 0xff; + int mask = (kcontrol->private_value >> 24) & 0xff; + .... + } +]]> + + + + + + In get callback, you have to fill all the elements if the + control has more than one elements, + i.e. count > 1. + In the example above, we filled only one element + (value.integer.value[0]) since it's + assumed as count = 1. + +
+ +
+ put callback + + + This callback is used to write a value from the user-space. + + + + For example, + + + Example of put callback + +current_value != + ucontrol->value.integer.value[0]) { + change_current_value(chip, + ucontrol->value.integer.value[0]); + changed = 1; + } + return changed; + } +]]> + + + + As seen above, you have to return 1 if the value is + changed. If the value is not changed, return 0 instead. + If any fatal error happens, return a negative error code as + usual. + + + + Like get callback, + when the control has more than one elements, + all elemehts must be evaluated in this callback, too. + +
+ +
+ Callbacks are not atomic + + All these three callbacks are basically not atomic. + +
+
+ +
+ Constructor + + When everything is ready, finally we can create a new + control. For creating a control, there are two functions to be + called, snd_ctl_new1() and + snd_ctl_add(). + + + + In the simplest way, you can do like this: + + + + + + + + where my_control is the + snd_kcontrol_new_t object defined above, and chip + is the object pointer to be passed to + kcontrol->private_data + which can be referred in callbacks. + + + + snd_ctl_new1() allocates a new + snd_kcontrol_t instance (that's why the definition + of my_control can be with + __devinitdata + prefix), and snd_ctl_add assigns the given + control component to the card. + +
+ +
+ Change Notification + + If you need to change and update a control in the interrupt + routine, you can call snd_ctl_notify(). For + example, + + + + + + + + This function takes the card pointer, the event-mask, and the + control id pointer for the notification. The event-mask + specifies the types of notification, for example, in the above + example, the change of control values is notified. + The id pointer is the pointer of snd_ctl_elem_id_t + to be notified. + You can find some examples in es1938.c or + es1968.c for hardware volume interrupts. + +
+ + + + + + + + + API for AC97 Codec + +
+ General + + The ALSA AC97 codec layer is a well-defined one, and you don't + have to write many codes to control it. Only low-level control + routines are necessary. The AC97 codec API is defined in + <sound/ac97_codec.h>. + +
+ +
+ Full Code Example + + + Example of AC97 Interface + +private_data, return 0); + .... + // read a register value here from the codec + return the_register_value; + } + + static void snd_mychip_ac97_write(ac97_t *ac97, + unsigned short reg, unsigned short val) + { + mychip_t *chip = snd_magic_cast(mychip_t, + ac97->private_data, return 0); + .... + // write the given register value to the codec + } + + static int snd_mychip_ac97(mychip_t *chip) + { + ac97_t ac97; + + memset(&ac97, 0, sizeof(ac97)); + ac97.write = snd_mychip_ac97_write; + ac97.read = snd_mychip_ac97_read; + ac97.private_data = chip; + return snd_ac97_mixer(card, &ac97, &chip->ac97); + } + +]]> + + + +
+ +
+ Constructor + + For creating an ac97 instance, call + snd_ac97_mixer() with an ac97_t + record, in which the callbacks and the private_data is set. + + + +ac97); +]]> + + + + where chip->ac97 is the pointer of a newly created + ac97_t instance. + This instance is not necessarily stored in the chip + record. When you need to change the register values from the + driver, or need the suspend/resume of ac97 codecs, keep this + pointer to pass to the corresponding functions. + +
+ +
+ Callbacks + + The standard callbacks are read and + write. Obviously they + correspond to the functions for read and write accesses to the + hardware low-level codes. + + + + The read callback returns the + register value specified in the argument. + + + +private_data, return 0); + .... + return the_register_value; + } +]]> + + + + Here, the chip can be cast from ac97->private_data. + + + + Meanwhile, the write callback is + used to set the register value. + + + + + + + + + + These callbacks are non-atomic like the callbacks of control API + unless they are called during suspend/resume phase. + + + + There are also other callbacks: + reset, + wait and + init. + + + + The reset callback is used to reset + the codec. If the chip requires a special way of reset, you can + define this callback. + This callback must be atomic when it's called in the suspend + mode. + + + + The wait callback is used for a + certain wait at the standard initialization of the codec. If the + chip requires the extra wait-time, define this callback. + This callback is always non-atomic, because it's never called + in the resume mode. + + + + The init callback is used for + additional initialization of the codec. This callback is called + after the reset, and should be atomic in the resume mode. + +
+ +
+ Updating Registers in The Driver + + If you need to access to the codec from the driver, you can + call the following functions: + snd_ac97_write(), + snd_ac97_read(), + snd_ac97_update() and + snd_ac97_update_bits(). + + + + Both snd_ac97_write() and + snd_ac97_update() functions are used to + set a value to the given register + (AC97_XXX). The different between them is + that snd_ac97_update() doesn't write a + value if the given value has been already set, while + snd_ac97_write() always rewrites the + value. + + + + + + + + + + snd_ac97_read() is used to read the value + of the given register. For example, + + + + + + + + + + snd_ac97_update_bits() is used to update + some bits of the given register. + + + + + + + + + + Also, there is a function to change the sample rate (of a + certain register such as + AC97_PCM_FRONT_DAC_RATE) when VRA is + supported by the codec: + snd_ac97_set_rate(). + + + + + + + + + + The following registers are available for setting the rate: + AC97_PCM_MIC_ADC_RATE, + AC97_PCM_FRONT_DAC_RATE, + AC97_PCM_LR_ADC_RATE, + AC97_SPDIF. When the + AC97_SPDIF is specified, the register is + not really changed but the corresponding IEC958 status bits will + be updated. + +
+ +
+ Clock Adjustment + + On some chip, the clock of the codec isn't 48000 but using a + PCI clock (to save a quartz!). In this case, change the field + ac97->clock to the corresponding + value. For example, intel8x0 + and es1968 drivers have the auto-measurement function of the + clock. + +
+ +
+ Proc Files + + The ALSA AC97 interface will create a proc file such as + /proc/asound/card0/ac97#0 and + ac97#0regs. You can refer to these files to + see the current status and registers of the codec. + +
+ +
+ Multiple Codecs + + When there are several codecs on the same card, you need to + call snd_ac97_new() multiple times with + ac97.num=1 or greater. The num field + specifies the codec + number. + + + + If you have set up multiple codecs, you need to either write + different callbacks for each codec or check + ac97->num in the + callback routines. + +
+ + + + + + + + + MIDI (MPU401-UART) Interface + +
+ General + + Many soundcards have built-in MIDI (MPU401-UART) + interfaces. When the soundcard supports the standard MPU401-UART + interface, most likely you can use the ALSA MPU401-UART API. The + MPU401-UART API is defined in + <sound/mpu401.h>. + + + + Some soundchips have similar but a little bit different + implementation of mpu401 stuff. For example, emu10k1 has its own + mpu401 routines. + + + + In this document, I won't explain the rawmidi interface API, + which is the basis of MPU401-UART implementation. + + + + For details, please check the source, + core/rawmidi.c, and examples such as + drivers/mpu401/mpu401_uart.c or + usb/usbmidi.c. + +
+ +
+ Constructor + + For creating a rawmidi object, call + snd_mpu401_uart_new(). + + + + + + + + + + The first argument is the card pointer, and the second is the + index of this component. You can create up to 8 rawmidi + devices. + + + + The third argument is the type of the hardware, + MPU401_HW_XXX. If it's not a special one, + you can use MPU401_HW_MPU401. + + + + The 4th argument is the i/o port address. Many + backward-compatible MPU401 has an i/o port such as 0x330. Or, it + might be a part of its own PCI i/o region. It depends on the + chip design. + + + + When the i/o port address above is a part of the PCI i/o + region, the MPU401 i/o port might have been already allocated + (reserved) by the driver itself. In such a case, pass non-zero + to the 5th argument + (integrated). Otherwise, pass 0 to it, + and + the mpu401-uart layer will allocate the i/o ports by itself. + + + + Usually, the port address corresponds to the command port and + port + 1 corresponds to the data port. If not, you may change + the cport field of + mpu401_t manually + afterward. However, mpu401_t pointer is not + returned explicitly by + snd_mpu401_uart_new(). You need to cast + rmidi->private_data to + mpu401_t explicitly, + + + +private_data, ); +]]> + + + + and reset the cport as you like: + + + +cport = my_own_control_port; +]]> + + + + + + The 6th argument specifies the irq number for UART. If the irq + is already allocated, pass 0 to the 7th argument + (irq_flags). Otherwise, pass the flags + for irq allocation + (SA_XXX bits) to it, and the irq will be + reserved by the mpu401-uart layer. If the card doesn't generates + UART interrupts, pass -1 as the irq number. Then a timer + interrupt will be invoked for polling. + +
+ +
+ Interrupt Handler + + When the interrupt is allocated in + snd_mpu401_uart_new(), the private + interrupt handler is used, hence you don't have to do nothing + else than creating the mpu401 stuff. Otherwise, you have to call + snd_mpu401_uart_interrupt() explicitly when + a UART interrupt is invoked and checked in your own interrupt + handler. + + + + In this case, you need to pass the private_data of the + returned rawmidi object from + snd_mpu401_uart_new() as the second + argument of snd_mpu401_uart_interrupt(). + + + +private_data, regs); +]]> + + + +
+ + + + + + + + + Miscellaneous Devices + +
+ FM OPL3 + + The FM OPL3 is still used on many chips (mainly for backward + compatibility). ALSA has a nice OPL3 FM control layer, too. The + OPL3 API is defined in + <sound/opl3.h>. + + + + FM registers can be directly accessed through direct-FM API, + defined in <sound/asound_fm.h>. In + ALSA native mode, FM registers are accessed through + Hardware-Dependant Device direct-FM extension API, whereas in + OSS compatible mode, FM registers can be accessed with OSS + direct-FM compatible API on /dev/dmfmX device. + + + + For creating the OPL3 component, you have two functions to + call. The first one is a constructor for opl3_t + instance. + + + + + + + + + + The first argument is the card pointer, the second one is the + left port address, and the third is the right port address. In + most cases, the right port is placed at the left port + 2. + + + + The fourth argument is the hardware type. + + + + When the left and right ports have been already allocated by + the card driver, pass non-zero to the fifth argument + (integrated). Otherwise, opl3 module will + allocate the specified ports by itself. + + + + If this function returns successfully with 0, then create a + hwdep device for this opl3. + + + + + + + + + + The first argument is the opl3_t instance you + created, and the second is the index number, usually 0. + + + + The third argument is the index-offset for the sequencer + client assigned to the OPL3 port. When there is an MPU401-UART, + give 1 for here (UART always takes 0). + +
+ +
+ Hardware-Dependent Devices + + Some chips need the access from the user-space for special + controls or for loading the micro code. In such a case, you can + create a hwdep (hardware-dependent) device. The hwdep API is + defined in <sound/hwdep.h>. You can + find examples in opl3 driver or + isa/sb/sb16_csp.c. + + + + Creation of the hwdep instance is done via + snd_hwdep_new(). + + + + + + + + where the third argument is the index number. + + + + You can then pass any pointer value to the + private_data. Again, it should be a + magic-allocated record, so that the cast can be checked more + safely. If you assign a private data, you should define the + destructor, too. The destructor function is set to + private_free field. + + + +private_data = p; + hw->private_free = mydata_free; +]]> + + + + and the implementation of destructor would be: + + + +private_data, return); + snd_magic_kfree(p); + } +]]> + + + + + + The arbitrary file operations can be defined for this + instance. The file operators are defined in + ops table. For example, assume that + this chip needs an ioctl. + + + +ops.open = mydata_open; + hw->ops.ioctl = mydata_ioctl; + hw->ops.release = mydata_release; +]]> + + + + And implement the callback functions as you like. + +
+ +
+ IEC958 (S/PDIF) + + Usually the controls for IEC958 devices are implemented via + control interface. There is a macro to compose a name string for + IEC958 controls, SNDRV_CTL_NAME_IEC958() + defined in <include/asound.h>. + + + + There are some standard controls for IEC958 status bits. These + controls use the type SNDRV_CTL_ELEM_TYPE_IEC958, + and the size of element is fixed as 4 bytes array + (value.iec958.status[x]). For info + callback, you don't specify + the value field for this type (the count field must be set, + though). + + + + IEC958 Playback Con Mask is used to return the + bit-mask for the IEC958 status bits of consumer mode. Similarly, + IEC958 Playback Pro Mask returns the bitmask for + professional mode. They are read-only controls, and are defined + as MIXER controls (iface = + SNDRV_CTL_ELEM_IFACE_MIXER). + + + + Meanwhile, IEC958 Playback Default control is + defined for getting and setting the current default IEC958 + bits. Note that this one is usually defined as a PCM control + (iface = SNDRV_CTL_ELEM_IFACE_PCM), + although in some places it's defined as a MIXER control. + + + + In addition, you can define the control switches to + enable/disable or to set the raw bit mode. The implementation + will depend on the chip, but the control should be named as + IEC958 xxx, preferably using + SNDRV_CTL_NAME_IEC958() macro. + + + + You can find several cases, for example, + pci/emu10k1, + pci/ice1712, or + pci/cmipci.c. + +
+ + + + + + + + + Buffer and Memory Management + +
+ Buffer Types + + ALSA provides several different buffer allocation functions + depending on the bus and the architecture. All these have a + consistent API. The allocation of physically-contiguous pages is + done via + snd_malloc_xxx_pages() function, where xxx + is the bus type. + + + + The allocation of pages with fallback is + snd_malloc_xxx_pages_fallback(). This + function tries to allocate the specified pages but if the pages + are not available, it tries to reduce the page sizes until the + enough space is found. + + + + For releasing the space, call + snd_free_xxx_pages() function. + + + + Usually, ALSA drivers try to allocate and reserve + a large contiguous physical space + at the time the module is loaded for the later use. + This is called pre-allocation. + As already written, you can call the following function at the + construction of pcm instance (in the case of PCI bus). + + + + + + + + where size is the byte size to be + pre-allocated and the max is the maximal + size to be changed via prealloc proc file. + The allocator will try to get as the large area as possible + within the given size. + There are different versions of pre-allocator for different + buses. + + + + Once when the buffer is pre-allocated, you can use the + allocator in the hw_params callback + + + + + + + + Note that you have to pre-allocate to use this function + (i.e. you cannot use this function for + + a scatter-gather buffer). + +
+ +
+ External Hardware Buffers + + Some chips have their own hardware buffers and the DMA + transfer from the host memory is not available. In such a case, + you need to either 1) copy/set the audio data directly to the + external hardware buffer, or 2) make an intermediate buffer and + copy/set the data from it to the external hardware buffer in + interrupts (or in tasklets, preferably). + + + + The first case works fine if the external hardware buffer is enough + large. This method doesn't need any extra buffers and thus is + more effective. You need to define the + copy and + silence callbacks for + the data transfer. However, there is a drawback: it cannot + be mmapped. The examples are GUS's GF1 PCM or emu8000's + wavetable PCM. + + + + The second case allows the mmap of the buffer, although you have + to handle an interrupt or a tasklet for transferring the data + from the intermediate buffer to the hardware buffer. You can find an + example in vxpocket driver. + + + + Another case is that the chip uses a PCI memory-map + region for the buffer instead of the host memory. In this case, + mmap is available only on certain architectures like intel. In + non-mmap mode, the data cannot be transferred as the normal + way. Thus you need to define copy and + silence callbacks as well + as in the cases above. The examples are found in + rme32.c and rme96.c. + + + + The implementation of copy and + silence callbacks depends upon + whether the hardware supports interleaved or non-interleaved + samples. The copy callback is + defined like below, a bit + differently depending whether the direction is playback or + capture: + + + + + + + + + + In the case of interleaved samples, the second argument + (channel) is not used. The third argument + (pos) points the + current position offset in frames. + + + + The meaning of the fourth argument is different between + playback and capture. For playback, it holds the source data + pointer, and for capture, it's the destination data pointer. + + + + The last argument is the number of frames to be copied. + + + + What you have to do in this callback is again different + between playback and capture directions. In the case of + playback, you do: copy the given amount of data + (count) at the specified pointer + (src) to the specified offset + (pos) on the hardware buffer. When + coded like memcpy-like way, the copy would be like: + + + + + + + + + + For the capture direction, you do: copy the given amount of + data (count) at the specified offset + (pos) on the hardware buffer to the + specified pointer (dst). + + + + + + + + Note that both of the position and the data amount are given + in frames. + + + + In the case of non-interleaved samples, the implementation + will be a bit more complicated. + + + + You need to check the channel argument, and if it's -1, copy + the whole channels. Otherwise, you have to copy only the + specified channel. Please check + isa/gus/gus_pcm.c as an example. + + + + The silence callback is also + implemented in a similar way. + + + + + + + + + + The meanings of arguments are identical with the + copy + callback, although there is no src/dst + argument. In the case of interleaved samples, the channel + argument has no meaning, as well as on + copy callback. + + + + The role of silence callback is to + set the given amount + (count) of silence data at the + specified offset (pos) on the hardware + buffer. Suppose that the data format is signed (that is, the + silent-data is 0), and the implementation using a memset-like + function would be like: + + + + + + + + + + In the case of non-interleaved samples, again, the + implementation becomes a bit more complicated. See, for example, + isa/gus/gus_pcm.c. + +
+ +
+ Non-Contiguous Buffers + + If your hardware supports the page table like emu10k1 or the + buffer descriptors like via82xx, you can use the scatter-gather + (SG) DMA. ALSA provides an interface for handling SG-buffers. + The API is provided in <sound/pcm_sgbuf.h>. + + + + For creating the SG-buffer handler, call + snd_pcm_lib_preallocate_sg_pages() or + snd_pcm_lib_preallocate_sg_pages_for_all() + in the PCM constructor like other PCI pre-allocator. + You need to pass the + pci_dev struct pointer of the chip. + The snd_sg_buf_t instance is created as + substream->dma_private. You can cast + the pointer like: + + + +dma_private; +]]> + + + + + + Then call snd_pcm_lib_malloc_pages() + in hw_params callback + as well as in the case of normal PCI buffer. + The SG-buffer handler will allocate the non-contiguous kernel + pages of the given size and map them onto the virtually contiguous + memory. The virtual pointer is addressed in runtime->dma_area. + The physical address (runtime->dma_addr) is set to zero, + because the buffer is physically non-contigous. + The physical address table is set up in sgbuf->table. + You can get the physical address at a certain offset via + snd_pcm_sgbuf_get_addr(). + + + + When a SG-handler is used, you need to set + snd_pcm_sgbuf_ops_page as + the page callback. + + + + For releasing the data, call + snd_pcm_lib_free_pages() in the + hw_free callback as usual. + +
+ +
+ Vmalloc'ed Buffers + + It's possible to use a buffer allocated via + vmalloc, for example, for an intermediate + buffer. Since the allocated pages are not contiguous, you need + to set the page callback to obtain + the physical address at every offset. + + + + The implementation of page callback + would be like this: + + + + + + /* get the physical page pointer on the given offset */ + static struct page *mychip_page(snd_pcm_substream_t *substream, + unsigned long offset) + { + void *pageptr = substream->runtime->dma_area + offset; + return vmalloc_to_page(pageptr); + } +]]> + + + +
+ + + + + + + + + Proc Interface + + ALSA provides an easy interface for procfs. The proc files are + very useful for debugging. I recommend you set up proc files if + you write a driver and want to get a running status or register + dumps. The API is found in + <sound/info.h>. + + + + For creating a proc file, call + snd_card_proc_new(). + + + + + + + + where the second argument specifies the proc-file name to be + created. The above example will create a file + my-file under the card directory, + e.g. /proc/asound/card0/my-file. + + + + Like other components, the proc entry created via + snd_card_proc_new() will be registered and + released automatically in the card registration and release + functions. + + + + When the creation is successful, the function stores a new + instance at the pointer given in the third argument. + It is initialized as a text proc file for read only. For using + this proc file as a read-only text file as it is, set the read + callback with a private data via + snd_info_set_text_ops(). + + + + + + + + where the second argument (chip) is the + private data to be used in the callbacks and the third + (my_proc_read) is the callback function, which + is defined like + + + + + + + + + + + In the read callback, use snd_iprintf() for + output strings, which works just like normal + printf(). For example, + + + +private_data, return); + + snd_iprintf(buffer, "This is my chip!\n"); + snd_iprintf(buffer, "Port = %ld\n", chip->port); + } +]]> + + + + + + The file permission can be changed afterwards. As default, it's + set as read only for all users. If you want to add the write + permission to the user (root as default), set like below: + + + +mode = S_IFREG | S_IRUGO | S_IWUSR; +]]> + + + + and set the write buffer size and the callback + + + +c.text.write_size = 256; + entry->c.text.write = my_proc_write; +]]> + + + + + + The buffer size for read is set to 1024 implicitly by + snd_info_set_text_ops(). It should suffice + in most cases (the size will be aligned to + PAGE_SIZE anyway), but if you need to handle + very large text files, you can set it explicitly, too. + + + +c.text.read_size = 65536; +]]> + + + + + + For the write callback, you can use + snd_info_get_line() to get a text line, and + snd_info_get_str() to retrieve a string from + the line. Some examples are found in + core/oss/mixer_oss.c, core/oss/and + pcm_oss.c. + + + + For a raw-data proc-file, set the attributes like the following: + + + +content = SNDRV_INFO_CONTENT_DATA; + entry->private_data = chip; + entry->c.ops = &my_file_io_ops; + entry->size = 4096; + entry->mode = S_IFREG | S_IRUGO; +]]> + + + + + + The callback is much more complicated than the text-file + version. You need to use a low-level i/o functions such as + copy_from/to_user() to transfer the + data. Also, you have to keep tracking the file position, too. + + + +f_pos + size > local_max_size) + size = local_max_size - file->f_pos; + if (copy_to_user(buf, local_data + file->f_pos, size)) + return -EFAULT; + file->f_pos += size; + return size; + } +]]> + + + + + + + + + + + + Power Management + + If the chip is supposed to work with with suspend/resume + functions, you need to add the power-management codes to the + driver. The additional codes for the power-management should be + ifdef'ed with + CONFIG_PM. + + + + Basic jobs of suspend/resume are done in + suspend and + resume callbacks of + pci_driver struct. Unfortunately, the + API of these callbacks was changed at the middle time of Linux + 2.4.x, if you want to keep the support for older kernels, you + have to write two different callbacks. The example below is the + skeleton callbacks which just call the real suspend and resume + functions. + + + + + + + + + + The scheme of the real suspend job is as following. + + + Check whether the power-state is already D3hot. If yes, skip the job. + Call snd_pcm_suspend_all() to suspend the running PCM streams. + Save the register values if necessary. + Stop the hardware if necessary. + Set the power-state as D3hot by calling snd_power_change_state(). + + + + + A typical code would be like: + + + +card; + // (1) + if (card->power_state == SNDRV_CTL_POWER_D3hot) + return; + // (2) + snd_pcm_suspend_all(chip->pcm); + // (3) + snd_mychip_save_registers(chip); + // (4) + snd_mychip_stop_hardware(chip); + // (5) + snd_power_change_state(card, SNDRV_CTL_POWER_D3hot); + } +]]> + + + + + + The scheme of the real resume job is as following. + + + Check whether the power-state is already D0. + If yes, skip the job. + Enable the pci device again by calling + pci_enable_device(). + Re-initialize the chip. + Restore the saved registers if necessary. + Resume the mixer, e.g. calling + snd_ac97_resume(). + Restart the hardware (if any). + Set the power-state as D0 by calling + snd_power_change_state(). + + + + + A typical code would be like: + + + +card; + // (1) + if (card->power_state == SNDRV_CTL_POWER_D0) + return; + // (2) + pci_enable_device(chip->pci); + // (3) + snd_mychip_reinit_chip(chip); + // (4) + snd_mychip_restore_registers(chip); + // (5) + snd_ac97_resume(chip->ac97); + // (6) + snd_mychip_restart_chip(chip); + // (7) + snd_power_change_state(card, SNDRV_CTL_POWER_D0); + } +]]> + + + + + + In addition to the callbacks above, you should define a callback + for the changes via the ALSA control interface. It's defined + like below: + + + +power_state_private_data, return -ENXIO); + switch (power_state) { + case SNDRV_CTL_POWER_D0: + case SNDRV_CTL_POWER_D1: + case SNDRV_CTL_POWER_D2: + mychip_resume(chip); + break; + case SNDRV_CTL_POWER_D3hot: + case SNDRV_CTL_POWER_D3cold: + mychip_suspend(chip); + break; + default: + return -EINVAL; + } + return 0; + } +]]> + + + + + + OK, we have all callbacks now. Let's set up them now. In the + initialization of the card, add the following: + + + +set_power_state = snd_mychip_set_power_state; + card->power_state_private_data = chip; + #endif + .... + } +]]> + + + + + + If you need a space for saving the registers, you'll need to + allocate the buffer for it here, too, since you cannot call + kmalloc() with + GFP_KERNEL flag or + vmalloc() in the suspend callback. + The allocated buffer should be released in the corresponding + destructor. + + + + And next, set suspend/resume callbacks to the pci_driver, + + + + + + + + + + Last but not least: Please keep in mind that you cannot call + schedule() during the suspend and the resume + callbacks. If any delay is necessary, you have to use + mdelay() or udelay() + instead of schedule_timeout()! + Of course, semaphores cannot be used, too, which will invoke sleep + inside. + + + + + + + + + Module Parameters + + There are standard module options for ALSA. At least, each + module should have index, + id and enable + options. + + + + If the module supports multiple cards (usually up to + 8 = SNDRV_CARDS cards), they should be + arrays. The default initial values are defined already as + constants for ease of programming: + + + + + + + + + + If the module supports only a single card, they could be single + variables, instead. enable option is not + always necessary in this case, but it wouldn't be so bad to have a + dummy option for compatibility. + + + + The module parameters must be declared with the standard + MODULE_PARM() and + MODULE_PARM_DESC() macros. The ALSA provides + an additional macro, MODULE_PARM_SYNTAX(), + for describing its syntax. The strings will be written to + /lib/modules/XXX/modules.generic_string + file. + + + + For convenience, the typical string arguments given to + MODULE_PARM_SYNTAX() are defined in + <sound/initval.h>, such as + SNDRV_ID_DESC or + SNDRV_ENABLED. + + + + The typical coding would be like below: + + + + + + + + + + Also, don't forget to define the module description, classes, + license and devices. Especially, the recent modprobe requires to + define the module license as GPL, etc., otherwise the system is + shown as tainted. + + + + + + + + + + For building the driver into kernel, you should define the + setup() function in addition, too. + ALSA provides get_id() function to retrieve + a string argument from the kernel boot parameters. + + + += SNDRV_CARDS) + return 0; + (void)(get_option(&str,&enable[nr_dev]) == 2 && + get_option(&str,&index[nr_dev]) == 2 && + get_id(&str,&id[nr_dev]) == 2); + nr_dev++; + return 1; + } + + __setup("snd-mychip=", alsa_card_mychip_setup); + + #endif /* ifndef MODULE */ +]]> + + + + + + + + + + + Useful Functions + +
+ <function>snd_printk()</function> and friends + + ALSA provides a verbose version of + printk() function. If a kernel config + CONFIG_SND_VERBOSE_PRINTK is set, this + function prints the given message together with the file name + and the line of the caller. The KERN_XXX + prefix is processed as + well as the original printk() does, so it's + recommended to add this prefix, e.g. + + + + + + + + + + There are also printk()'s for + debugging. snd_printd() can be used for + general debugging purposes. If + CONFIG_SND_DEBUG is set, this function is + compiled, and works just like + snd_printk(). If the ALSA is compiled + without the debugging flag, it's ignored. + + + + snd_printdd() is compiled in only when + CONFIG_SND_DEBUG_DETECT is set. Please note + that DEBUG_DETECT is not set as default + even if you configure the alsa-driver with + option. You need to give + explicitly option instead. + +
+ +
+ <function>snd_assert()</function> + + snd_assert() macro is similar with the + normal assert() macro. For example, + + + + + + + + + + The first argument is the expression to evaluate, and the + second argument is the action if it fails. When + CONFIG_SND_DEBUG, is set, it will show an + error message such as BUG? (xxx) (called from + yyy). When no debug flag is set, this is + ignored. + +
+ +
+ <function>snd_runtime_check()</function> + + This macro is quite similar with + snd_assert(). Unlike + snd_assert(), the expression is always + evaluated regardless of + CONFIG_SND_DEBUG. When + CONFIG_SND_DEBUG is set, the macro will + show a message like ERROR (xx) (called from + yyy). + +
+ +
+ <function>snd_BUG()</function> + + It calls snd_assert(0,) -- that is, just + prints the error message at the point. It's useful to show that + a fatal error happens there. + +

This shows in the same syntax of +/dev/sndstat, which is available on the commercial OSS driver. +On ALSA, you can symlink /dev/sndstat to this proc file. + +Please note that the devices listed in this proc file appear only +after the corresponding OSS-emulation module is loaded. Don't worry +even if "NOT ENABLED IN CONFIG" is shown in it. + + +Device Mapping +============== + +ALSA supports the following OSS device files: + + PCM: + /dev/dspX + /dev/adspX + + Mixer: + /dev/mixerX + + MIDI: + /dev/midi0X + /dev/amidi0X + + Sequencer: + /dev/sequencer + /dev/sequencer2 (aka /dev/music) + +where X is the card number from 0 to 7. + +(NOTE: Some distributions have the device files like /dev/midi0 and + /dev/midi1. They are NOT for OSS but for tclmidi, which is + a totally different thing.) + +Unlike the real OSS, ALSA cannot use the device files more than the +assigned ones. For example, the first card cannot use /dev/dsp1 or +/dev/dsp2, but only /dev/dsp0 and /dev/adsp0. + +As seen above, PCM and MIDI may have two devices. Usually, the first +PCM device (hw:0,0 in ALSA) is mapped to /dev/dsp and the secondary +device (hw:0,1) to /dev/adsp (if available). For MIDI, /dev/midi and +/dev/amidi, respectively. + +You can change this device mapping via the module options of +snd-pcm-oss and snd-rawmidi. In the case of PCM, the following +options are available for snd-pcm-oss: + + dsp_map PCM device number assigned to /dev/dspX + (default = 0) + adsp_map PCM device number assigned to /dev/adspX + (default = 1) + +For example, to map the third PCM device (hw:0,2) to /dev/adsp0, +define like this: + + options snd-pcm-oss adsp_map=2 + +The options take arrays. For configuring the second card, specify +two entries separated by comma. For example, to map the third PCM +device on the second card to /dev/adsp1, define like below: + + options snd-pcm-oss adsp_map=0,2 + +To change the mapping of MIDI devices, the following options are +available for snd-rawmidi: + + midi_map MIDI device number assigned to /dev/midi0X + (default = 0) + amidi_map MIDI device number assigned to /dev/amidi0X + (default = 1) + +For example, to assign the third MIDI device on the first card to +/dev/midi00, define as follows: + + options snd-rawmidi midi_map=2 + + +PCM Mode +======== + +As default, ALSA emulates the OSS PCM with so-called plugin layer, +i.e. tries to convert the sample format, rate or channels +automatically when the card doesn't support it natively. +This will lead to some problems for some applications like quake or +wine, especially if they use the card only in the MMAP mode. + +In such a case, you can change the behavior of PCM per application by +writing a command to the proc file. There is a proc file for each PCM +stream, /proc/asound/cardX/pcmY[cp]/oss, where X is the card number +(zero-based), Y the PCM device number (zero-based), and 'p' is for +playback and 'c' for capture, respectively. Note that this proc file +exists only after snd-pcm-oss module is loaded. + +The command sequence has the following syntax: + + app_name fragments fragment_size [options] + +app_name is the name of application with (higher priority) or without +path. +fragments specifies the number of fragments or zero if no specific +number is given. +fragment_size is the size of fragment in bytes or zero if not given. +options is the optional parameters. The following options are +available: + + disable the application tries to open a pcm device for + this channel but does not want to use it. + direct don't use plugins + block force block open mode + non-block force non-block open mode + +The disable option is useful when one stream direction (playback or +capture) is not handled correctly by the application although the +hardware itself does support both directions. +The direct option is used, as mentioned above, to bypass the automatic +conversion and useful for MMAP-applications. +For example, to playback the first PCM device without plugins for +quake, send a command via echo like the following: + + % echo "quake 0 0 direct" > /proc/asound/card0/pcm0p/oss + +While quake wants only playback, you may append the second command +to notify driver that only this direction is about to be allocated: + + % echo "quake 0 0 disable" > /proc/asound/card0/pcm0c/oss + +The permission of proc files depend on the module options of snd. +As default it's set as root, so you'll likely need to be superuser for +sending the command above. + +The block and non-block options are used to change the behavior of +opening the device file. +As default, ALSA behaves as defined in POSIX, i.e. blocks the file +when it's busy until the device becomes free (unless O_NONBLOCK is +specified). Some applications assume the non-block open behavior, +which are actually implemented in some real OSS drivers. + +This blocking behavior can be changed globally via nonblock_open +module option of snd-pcm-oss. For using the non-block mode as default +for OSS devices, define like the following: + + options snd-pcm-oss nonblock_open=1 + +You can check the currently defined configuration by reading the proc +file. The read image can be sent to the proc file again, hence you +can save the current configuration + + % cat /proc/asound/card0/pcm0p/oss > /somewhere/oss-cfg + +and restore it like + + % cat /somewhere/oss-cfg > /proc/asound/card0/pcm0p/oss + +Also, for clearing all the current configuration, send "erase" command +as below: + + % echo "erase" > /proc/asound/card0/pcm0p/oss + + +Mixer Elements +============== + +Since ALSA has completely different mixer interface, the emulation of +OSS mixer is relatively complicated. ALSA builds up a mixer element +from several different ALSA (mixer) controls based on the name +string. For example, the volume element SOUND_MIXER_PCM is composed +from "PCM Playback Volume" and "PCM Playback Switch" controls for the +playback direction and from "PCM Capture Volume" and "PCM Capture +Switch" for the capture directory (if exists). When the PCM volume of +OSS is changed, all the volume and switch controls above are adjusted +automatically. + +As default, ALSA uses the following control for OSS volumes: + + OSS volume ALSA control Index + ----------------------------------------------------- + SOUND_MIXER_VOLUME Master 0 + SOUND_MIXER_BASS Tone Control - Bass 0 + SOUND_MIXER_TREBLE Tone Control - Treble 0 + SOUND_MIXER_SYNTH Synth 0 + SOUND_MIXER_PCM PCM 0 + SOUND_MIXER_SPEAKER PC Speaker 0 + SOUND_MIXER_LINE Line 0 + SOUND_MIXER_MIC Mic 0 + SOUND_MIXER_CD CD 0 + SOUND_MIXER_IMIX Monitor Mix 0 + SOUND_MIXER_ALTPCM PCM 1 + SOUND_MIXER_RECLEV (not assigned) + SOUND_MIXER_IGAIN Capture 0 + SOUND_MIXER_OGAIN Playback 0 + SOUND_MIXER_LINE1 Aux 0 + SOUND_MIXER_LINE2 Aux 1 + SOUND_MIXER_LINE3 Aux 2 + SOUND_MIXER_DIGITAL1 Digital 0 + SOUND_MIXER_DIGITAL2 Digital 1 + SOUND_MIXER_DIGITAL3 Digital 2 + SOUND_MIXER_PHONEIN Phone 0 + SOUND_MIXER_PHONEOUT Phone 1 + SOUND_MIXER_VIDEO Video 0 + SOUND_MIXER_RADIO Radio 0 + SOUND_MIXER_MONITOR Monitor 0 + +The second column is the base-string of the corresponding ALSA +control. In fact, the controls with "XXX [Playback|Capture] +[Volume|Switch]" will be checked in addition. + +The current assignment of these mixer elements is listed in the proc +file, /proc/asound/cardX/mixer_oss, which will be like the following + + VOLUME "Master" 0 + BASS "" 0 + TREBLE "" 0 + SYNTH "" 0 + PCM "PCM" 0 + ... + +where the first column is the OSS volume element, the second column +the base-string of the corresponding ALSA control, and the third the +control index. When the string is empty, it means that the +corresponding OSS control is not available. + +For changing the assignment, you can write the configuration to this +proc file. For example, to map "Wave Playback" to the PCM volume, +send the command like the following: + + % echo 'VOLUME "Wave Playback" 0' > /proc/asound/card0/mixer_oss + +The command is exactly as same as listed in the proc file. You can +change one or more elements, one volume per line. In the last +example, both "Wave Playback Volume" and "Wave Playback Switch" will +be affected when PCM volume is changed. + +Like the case of PCM proc file, the permission of proc files depend on +the module options of snd. you'll likely need to be superuser for +sending the command above. + +As well as in the case of PCM proc file, you can save and restore the +current mixer configuration by reading and writing the whole file +image. + + +Unsupported Features +==================== + +MMAP on ICE1712 driver +---------------------- +ICE1712 supports only the unconventional format, interleaved +10-channels 24bit (packed in 32bit) format. Therefore you cannot mmap +the buffer as the conventional (mono or 2-channels, 8 or 16bit) format +on OSS. + +USB devices +----------- +Some USB devices support only 24bit format packed in 3bytes. This +format is not supported by OSS and no conversion is provided by kernel +OSS emulation. You can use the user-space OSS emulation via libaoss +instead. + diff -urN linux-2.4.21-rc1.orig/Documentation/ALSA/SB-Live-mixer.txt linux/Documentation/ALSA/SB-Live-mixer.txt --- linux-2.4.21-rc1.orig/Documentation/ALSA/SB-Live-mixer.txt 1969-12-31 17:00:00.000000000 -0700 +++ linux/Documentation/ALSA/SB-Live-mixer.txt 2002-03-06 00:49:31.000000000 -0700 @@ -0,0 +1,356 @@ + + Sound Blaster Live mixer / default DSP code + =========================================== + + +The EMU10K1 chips have a DSP part which can be programmed to support +various ways of sample processing, which is described here. +(This acticle does not deal with the overall functionality of the +EMU10K1 chips.

Copyright (c) 1998,1999 by Takashi Iwai +<iwai@ww.uni-erlangen.de> +

ver.0.1.8; Nov. 16, 1999 +

+ +

+ +

+1. Description

+This directory contains the OSS sequencer emulation driver on ALSA. Note +that this program is still in the development state. +

What this does - it provides the emulation of the OSS sequencer, access +via +/dev/sequencer and /dev/music devices. +The most of applications using OSS can run if the appropriate ALSA +sequencer is prepared. +

The following features are emulated by this driver: +

    +
  • +Normal sequencer and MIDI events:
    • + +
    They are converted to the ALSA sequencer events, and sent to the corresponding +port. +
  • +Timer events:
    • + +
    The timer is not selectable by ioctl. The control rate is fixed to +100 regardless of HZ. That is, even on Alpha system, a tick is always +1/100 second. The base rate and tempo can be changed in /dev/music. + +
  • +Patch loading:
    • + +
    It purely depends on the synth drivers whether it's supported since +the patch loading is realized by callback to the synth driver. +
  • +I/O controls:
    • + +
    Most of controls are accepted. Some controls +are dependent on the synth driver, as well as even on original OSS.
+Furthermore, you can find the following advanced features: +
    +
  • +Better queue mechanism:
    • + +
    The events are queued before processing them. +
  • +Multiple applications:
    • + +
    You can run two or more applications simultaneously (even for OSS sequencer)! +However, each MIDI device is exclusive - that is, if a MIDI device is opened +once by some application, other applications can't use it. No such a restriction +in synth devices. +
  • +Real-time event processing:
    • + +
    The events can be processed in real time without using out of bound +ioctl. To switch to real-time mode, send ABSTIME 0 event. The followed +events will be processed in real-time without queued. To switch off the +real-time mode, send RELTIME 0 event. +
  • +/proc interface:
    • + +
    The status of applications and devices can be shown via /proc/asound/seq/oss +at any time. In the later version, configuration will be changed via /proc +interface, too.
+ +

+2. Installation

+Run configure script with both sequencer support (--with-sequencer=yes) +and OSS emulation (--with-oss=yes) options. A module snd-seq-oss.o +will be created. If the synth module of your sound card supports for OSS +emulation (so far, only Emu8000 driver), this module will be loaded automatically. +Otherwise, you need to load this module manually. +

At beginning, this module probes all the MIDI ports which have been +already connected to the sequencer. Once after that, the creation and deletion +of ports are watched by announcement mechanism of ALSA sequencer. +

The available synth and MIDI devices can be found in proc interface. +Run "cat /proc/asound/seq/oss", and check the devices. For example, +if you use an AWE64 card, you'll see like the following: +

        OSS sequencer emulation version 0.1.8
+        ALSA client number 63
+        ALSA receiver port 0
+
+        Number of applications: 0
+
+        Number of synth devices: 1
+
+        synth 0: [EMU8000]
+          type 0x1 : subtype 0x20 : voices 32
+          capabilties : ioctl enabled / load_patch enabled
+
+        Number of MIDI devices: 3
+
+        midi 0: [Emu8000 Port-0] ALSA port 65:0
+          capability write / opened none
+
+        midi 1: [Emu8000 Port-1] ALSA port 65:1
+          capability write / opened none
+
+        midi 2: [0: MPU-401 (UART)] ALSA port 64:0
+          capability read/write / opened none
+Note that the device number may be different from the information of +/proc/asound/oss-devices +or ones of the original OSS driver. Use the device number listed in /proc/asound/seq/oss +to play via OSS sequencer emulation. +

+3. Using Synthesizer Devices

+Run your favorite program. I've tested playmidi-2.4, awemidi-0.4.3, gmod-3.1 +and xmp-1.1.5. You can load samples via /dev/sequencer like sfxload, +too. +

If the lowlevel driver supports multiple access to synth devices (like +Emu8000 driver), two or more applications are allowed to run at the same +time. +

+4. Using MIDI Devices

+So far, only MIDI output was tested. MIDI input was not checked at all, +but hopefully it will work. Use the device number listed in /proc/asound/seq/oss. +Be aware that these numbers are mostly different from the list in +/proc/asound/oss-devices. +

+5. Module Options

+The following module options are available: +
    +
  • +maxqlen
    • + +
    specifies the maximum read/write queue length. This queue is private +for OSS sequencer, so that it is independent from the queue length of ALSA +sequencer. Default value is 1024. +
  • +seq_oss_debug
    • + +
    specifies the debug level and accepts zero (= no debug message) or +positive integer. Default value is 0.
+ +

+6. Queue Mechanism

+OSS sequencer emulation uses an ALSA priority queue. The +events from /dev/sequencer are processed and put onto the queue +specified by module option. +

All the events from /dev/sequencer are parsed at beginning. +The timing events are also parsed at this moment, so that the events may +be processed in real-time. Sending an event ABSTIME 0 switches the operation +mode to real-time mode, and sending an event RELTIME 0 switches it off. +In the real-time mode, all events are dispatched immediately. +

The queued events are dispatched to the corresponding ALSA sequencer +ports after scheduled time by ALSA sequencer dispatcher. +

If the write-queue is full, the application sleeps until a certain amount +(as default one half) becomes empty in blocking mode. The synchronization +to write timing was implemented, too. +

The input from MIDI devices or echo-back events are stored on read FIFO +queue. If application reads /dev/sequencer in blocking mode, the +process will be awaked. + +

+7. Interface to Synthesizer Device

+ +

+7.1. Registration

+To register an OSS synthesizer device, use snd_seq_oss_synth_register +function. +
int snd_seq_oss_synth_register(char *name, int type, int subtype, int nvoices,
+                              snd_seq_oss_callback_t *oper, void *private_data)
+The arguments name, type, subtype and +nvoices +are used for making the appropriate synth_info structure for ioctl. The +return value is an index number of this device. This index must be remembered +for unregister. If registration is failed, -errno will be returned. +

To release this device, call snd_seq_oss_synth_unregister function: +

int snd_seq_oss_synth_unregister(int index),
+where the index is the index number returned by register function. +

+7.2. Callbacks

+OSS synthesizer devices have capability for sample downloading and ioctls +like sample reset. In OSS emulation, these special features are realized +by using callbacks. The registration argument oper is used to specify these +callbacks. The following callback functions must be defined: +
snd_seq_oss_callback_t:
+        int (*open)(snd_seq_oss_arg_t *p, void *closure);
+        int (*close)(snd_seq_oss_arg_t *p);
+        int (*ioctl)(snd_seq_oss_arg_t *p, unsigned int cmd, unsigned long arg);
+        int (*load_patch)(snd_seq_oss_arg_t *p, int format, const char *buf, int offs, int count);
+        int (*reset)(snd_seq_oss_arg_t *p);
+Except for open and close callbacks, they are allowed
+to be NULL.
+
Each callback function takes the argument type snd_seq_oss_arg_t as the
+first argument.
+
struct snd_seq_oss_arg_t {
+        int app_index;
+        int file_mode;
+        int seq_mode;
+        snd_seq_addr_t addr;
+        void *private_data;
+        int event_passing;
+};

+The first three fields, app_index, file_mode and
+seq_mode
+are initialized by OSS sequencer. The app_index is the application
+index which is unique to each application opening OSS sequencer. The
+file_mode
+is bit-flags indicating the file operation mode. See
+seq_oss.h
+for its meaning. The seq_mode is sequencer operation mode. In
+the current version, only SND_OSSSEQ_MODE_SYNTH is used.
+
The next two fields, addr and private_data, must be
+filled by the synth driver at open callback. The addr contains
+the address of ALSA sequencer port which is assigned to this device. If
+the driver allocates memory for private_data, it must be released
+in close callback by itself.
+
The last field, event_passing, indicates how to translate note-on
+/ off events. In PROCESS_EVENTS mode, the note 255 is regarded
+as velocity change, and key pressure event is passed to the port. In PASS_EVENTS
+mode, all note on/off events are passed to the port without modified. PROCESS_KEYPRESS
+mode checks the note above 128 and regards it as key pressure event (mainly
+for Emu8000 driver).
+

+7.2.1. Open Callback

+The open is called at each time this device is opened by an application
+using OSS sequencer. This must not be NULL. Typically, the open callback
+does the following procedure:
+
    
+
  1. 
+Allocate private data record.
    2. 
+
+
  2. 
+Create an ALSA sequencer port.
    3. 
+
+
  3. 
+Set the new port address on arg->addr.
    4. 
+
+
  4. 
+Set the private data record pointer on arg->private_data.
    5. 
+

+Note that the type bit-flags in port_info of this synth port must NOT contain
+TYPE_MIDI_GENERIC
+bit. Instead, TYPE_SPECIFIC should be used. Also, CAP_SUBSCRIPTION
+bit should NOT be included, too. This is necessary to tell it from other
+normal MIDI devices. If the open procedure succeeded, return zero. Otherwise,
+return -errno.
+

+7.2.2 Ioctl Callback

+The ioctl callback is called when the sequencer receives device-specific
+ioctls. The following two ioctls should be processed by this callback:
+
    
+
  • 
+IOCTL_SEQ_RESET_SAMPLES
    • 
+
+
    reset all samples on memory -- return 0
+
  • 
+IOCTL_SYNTH_MEMAVL
    • 
+
+
    return the available memory size
+
  • 
+FM_4OP_ENABLE
    • 
+
+
    can be ignored usually

+The other ioctls are processed inside the sequencer without passing to
+the lowlevel driver.
+

+7.2.3 Load_Patch Callback

+The load_patch callback is used for sample-downloading. This callback
+must read the data on user-space and transfer to each device. Return 0
+if succeeded, and -errno if failed. The format argument is the patch key
+in patch_info record. The buf is user-space pointer where patch_info record
+is stored. The offs can be ignored. The count is total data size of this
+sample data.
+

+7.2.4 Close Callback

+The close callback is called when this device is closed by the
+applicaion. If any private data was allocated in open callback, it must
+be released in the close callback. The deletion of ALSA port should be
+done here, too. This callback must not be NULL.
+

+7.2.5 Reset Callback

+The reset callback is called when sequencer device is reset or
+closed by applications. The callback should turn off the sounds on the
+relevant port immediately, and initialize the status of the port. If this
+callback is undefined, OSS seq sends a HEARTBEAT event to the
+port.
+

+7.3 Events

+Most of the events are processed by sequencer and translated to the adequate
+ALSA sequencer events, so that each synth device can receive by input_event
+callback of ALSA sequencer port. The following ALSA events should be implemented
+by the driver:

+
+
The most of these behavior can be realized by MIDI emulation driver
+included in the Emu8000 lowlevel driver. In the future release, this module
+will be independent.
+
Some OSS events (SEQ_PRIVATE and SEQ_VOLUME events) are passed as event
+type SND_SEQ_OSS_PRIVATE.  The OSS sequencer passes these event 8 byte
+packets without any modification. The lowlevel driver should process these
+events appropriately.
+

+8. Interface to MIDI Device

+Since the OSS emulation probes the creation and deletion of ALSA MIDI sequencer
+ports automatically by receiving announcement from ALSA sequencer, the
+MIDI devices don't need to be registered explicitly like synth devices.
+However, the MIDI port_info registered to ALSA sequencer must include a group
+name SND_SEQ_GROUP_DEVICE and a capability-bit CAP_READ or
+CAP_WRITE. Also, subscription capabilities, CAP_SUBS_READ or CAP_SUBS_WRITE,
+must be defined, too. If these conditions are not satisfied, the port is not
+registered as OSS sequencer MIDI device.
+
The events via MIDI devices are parsed in OSS sequencer and converted
+to the corresponding ALSA sequencer events. The input from MIDI sequencer
+is also converted to MIDI byte events by OSS sequencer. This works just
+a reverse way of seq_midi module.
+

+9. Known Problems / TODO's

+
+
    
+
  • 
+Patch loading via ALSA instrument layer is not implemented yet.
    •

+
+			Serial UART 16450/16550 MIDI driver
+			===================================
+
+The adaptor module parameter allows you to select either:
+
+  0 - Roland Soundcanvas support (default)
+  1 - Midiator MS-124T support (1)
+  2 - Midiator MS-124W S/A mode (2)
+  3 - MS-124W M/B mode support (3)
+  4 - Generic device with multiple input support (4)
+
+For the Midiator MS-124W, you must set the physical M-S and A-B
+switches on the Midiator to match the driver mode you select.
+
+In Roland Soundcanvas mode, multiple ALSA raw MIDI substreams are supported
+(midiCnD0-midiCnD15).  Whenever you write to a different substream, the driver
+sends the nonstandard MIDI command sequence F5 NN, where NN is the substream
+number plus 1.  Roland modules use this command to switch between different
+"parts", so this feature lets you treat each part as a distinct raw MIDI
+substream. The driver provides no way to send F5 00 (no selection) or to not
+send the F5 NN command sequence at all; perhaps it ought to.
+
+Usage example for simple serial converter:
+
+	/sbin/setserial /dev/ttyS0 none
+	/sbin/modprobe snd-serial-u16550 port=0x3f8 irq=4 speed=115200
+
+Usage example for Roland SoundCanvas with 4 MIDI ports:
+
+	/sbin/setserial /dev/ttyS0 none
+	/sbin/modprobe snd-serial-u16550 port=0x3f8 irq=4 outs=4
+
+In MS-124T mode, one raw MIDI substream is supported (midiCnD0); the outs
+module parameter is automatically set to 1. The driver sends the same data to
+all four MIDI Out connectors.  Set the A-B switch and the speed module
+parameter to match (A=19200, B=9600).
+
+Usage example for MS-124T, with A-B switch in A position:
+
+	/sbin/setserial /dev/ttyS0 none
+	/sbin/modprobe snd-serial-u16550 port=0x3f8 irq=4 adaptor=1 \
+			speed=19200
+
+In MS-124W S/A mode, one raw MIDI substream is supported (midiCnD0);
+the outs module parameter is automatically set to 1. The driver sends
+the same data to all four MIDI Out connectors at full MIDI speed.
+
+Usage example for S/A mode:
+
+	/sbin/setserial /dev/ttyS0 none
+	/sbin/modprobe snd-serial-u16550 port=0x3f8 irq=4 adaptor=2
+
+In MS-124W M/B mode, the driver supports 16 ALSA raw MIDI substreams;
+the outs module parameter is automatically set to 16.  The substream
+number gives a bitmask of which MIDI Out connectors the data should be
+sent to, with midiCnD1 sending to Out 1, midiCnD2 to Out 2, midiCnD4 to
+Out 3, and midiCnD8 to Out 4.  Thus midiCnD15 sends the data to all 4 ports.
+As a special case, midiCnD0 also sends to all ports, since it is not useful
+to send the data to no ports.  M/B mode has extra overhead to select the MIDI
+Out for each byte, so the aggregate data rate across all four MIDI Outs is
+at most one byte every 520 us, as compared with the full MIDI data rate of
+one byte every 320 us per port.
+
+Usage example for M/B mode:
+
+	/sbin/setserial /dev/ttyS0 none
+	/sbin/modprobe snd-serial-u16550 port=0x3f8 irq=4 adaptor=3
+
+The MS-124W hardware's M/A mode is currently not supported. This mode allows
+the MIDI Outs to act independently at double the aggregate throughput of M/B,
+but does not allow sending the same byte simultaneously to multiple MIDI Outs. 
+The M/A protocol requires the driver to twiddle the modem control lines under
+timing constraints, so it would be a bit more complicated to implement than
+the other modes.
+
+Midiator models other than MS-124W and MS-124T are currently not supported. 
+Note that the suffix letter is significant; the MS-124 and MS-124B are not
+compatible, nor are the other known models MS-101, MS-101B, MS-103, and MS-114.
+I do have documentation (tim.mann@compaq.com) that partially covers these models,
+but no units to experiment with.  The MS-124W support is tested with a real unit.
+The MS-124T support is untested, but should work.
+
+The Generic driver supports multiple input and output substreams over a single
+serial port.  Similar to Roland Soundcanvas mode, F5 NN is used to select the
+appropriate input or output stream (depending on the data direction).
+Additionally, the CTS signal is used to regulate the data flow.  The number of
+inputs is specified by the ins parameter.

   driver as a module, you can specify the number of presses at load
   time with "insmod button reboot_count=".
 
+CONFIG_SOUND_SUPPORT
+  If you have a sound card in your computer, i.e. if it can say more
+  than an occasional beep, say Y.  Be sure to have all the information
+  about your sound card and its configuration down (I/O port,
+  interrupt and DMA channel), because you will be asked for it.
+
+  You want to read the Sound-HOWTO, available from
+  . General information about
+  the modular sound system is contained in the files
+  .  The file
+   contains some slightly
+  outdated but still useful information as well.
+
+  If you have a PnP sound card and you want to configure it at boot
+  time using the ISA PnP tools (read
+  ), then you need to

+ *
+ *
+ *      The OPL-3 mode is switched on by writing 0x01, to the offset 5
+ *      of the right side.
+ *
+ *      Another special register at the right side is at offset 4. It contains
+ *      a bit mask defining which voices are used as 4 OP voices.
+ *
+ *      The percussive mode is implemented in the left side only.
+ *
+ *      With the above exceptions the both sides can be operated independently.
+ *      
+ *      A 4 OP voice can be created by setting the corresponding
+ *      bit at offset 4 of the right side.
+ *
+ *      For example setting the rightmost bit (0x01) changes the
+ *      first voice on the right side to the 4 OP mode. The fourth
+ *      voice is made inaccessible.
+ *
+ *      If a voice is set to the 2 OP mode, it works like 2 OP modes
+ *      of the original YM3812 (AdLib). In addition the voice can 
+ *      be connected the left, right or both stereo channels. It can
+ *      even be left unconnected. This works with 4 OP voices also.
+ *
+ *      The stereo connection bits are located in the FEEDBACK_CONNECTION
+ *      register of the voice (0xC0-0xC8). In 4 OP voices these bits are
+ *      in the second half of the voice.

+     the case on the original platform, MS-DOS). If this is not done,
+     then WavePatch-format files cannot be read/written correctly.

+/***************************************************************************************************
+*
+* To understand what Alsa Drivers should be doing look at "Writing an Alsa Driver" by Takashi Iwai
+* available in the Alsa doc section on the website		
+* 
+* A few notes to make things clearer. The UDA1341 is hooked up to Serial port 4 on the SA1100.
+* We are using  SSP mode to talk to the UDA1341. The UDA1341 bit & wordselect clocks are generated
+* by this UART. Unfortunately, the clock only runs if the transmit buffer has something in it.
+* So, if we are just recording, we feed the transmit DMA stream a bunch of 0x0000 so that the
+* transmit buffer is full and the clock keeps going. The zeroes come from FLUSH_BASE_PHYS which
+* is a mem loc that always decodes to 0's w/ no off chip access.
+*
+* Some alsa terminology:
+*	frame => num_channels * sample_size  e.g stereo 16 bit is 2 * 16 = 32 bytes
+*	period => the least number of bytes that will generate an interrupt e.g. we have a 1024 byte
+*             buffer and 4 periods in the runtime structure this means we'll get an int every 256
+*             bytes or 4 times per buffer.
+*             A number of the sizes are in frames rather than bytes, use frames_to_bytes and
+*             bytes_to_frames to convert.  The easiest way to tell the units is to look at the
+*             type i.e. runtime-> buffer_size is in frames and its type is snd_pcm_uframes_t
+*             
+*	Notes about the pointer fxn:
+*	The pointer fxn needs to return the offset into the dma buffer in frames.
+*	Interrupts must be blocked before calling the dma_get_pos fxn to avoid race with interrupts.
+*
+*	Notes about pause/resume
+*	Implementing this would be complicated so it's skipped.  The problem case is:
+*	A full duplex connection is going, then play is paused. At this point you need to start xmitting
+*	0's to keep the record active which means you cant just freeze the dma and resume it later you'd
+*	need to	save off the dma info, and restore it properly on a resume.  Yeach!
+*
+*	Notes about transfer methods:
+*	The async write calls fail.  I probably need to implement something else to support them?

+ * This device handler separates the card driver module from sequencer

+ * to spend unnecessary resources e.g. if he needs only listening to
+ * MP3s.
+ *
+ * The card (or lowlevel) driver creates a sequencer device entry
+ * via snd_seq_device_new().  This is an entry pointer to communicate
+ * with the sequencer device "driver", which is involved with the
+ * actual part to communicate with the sequencer core.
+ * Each sequencer device entry has an id string and the corresponding
+ * driver with the same id is loaded when required.  For example,
+ * lowlevel codes to access emu8000 chip on sbawe card are included in
+ * emu8000-synth module.  To activate this module, the hardware
+ * resources like i/o port are passed via snd_seq_device argument.

+
+  Sequencer MIDI-through client
+
+  This gives a simple midi-through client.  All the normal input events
+  are redirected to output port immediately.
+  The routing can be done via aconnect program in alsa-utils.
+
+  Each client has a static client number 62 (= SNDRV_SEQ_CLIENT_DUMMY).
+  If you want to auto-load this module, you may add the following alias
+  in your /etc/conf.modules file.
+
+	alias snd-seq-client-62  snd-seq-dummy
+
+  The module is loaded on demand for client 62, or /proc/asound/seq/
+  is accessed.  If you don't need this module to be loaded, alias
+  snd-seq-client-62 as "off".  This will help modprobe.
+
+  The number of ports to be created can be specified via the module
+  paramter "ports".  For example, to create four ports, add the
+  following option in /etc/modules.conf:
+
+	option snd-seq-dummy ports=4
+
+  The modle option "duplex=1" enables duplex operation to the port.
+  In duplex mode, a pair of ports are created instead of single port,
+  and events are tunneled between pair-ports.  For example, input to
+  port A is sent to output port of another port B and vice versa.
+  In duplex mode, each port has DUPLEX capability.

+
+NOTE: the current implementation of the port structure as a linked list is
+not optimal for clients that have many ports. For sending messages to all
+subscribers of a port we first need to find the address of the port
+structure, which means we have to traverse the list. A direct access table
+(array) would be better, but big preallocated arrays waste memory.
+
+Possible actions:
+
+1) leave it this way, a client does normaly does not have more than a few
+ports
+
+2) replace the linked list of ports by a array of pointers which is
+dynamicly kmalloced. When a port is added or deleted we can simply allocate
+a new array, copy the corresponding pointers, and delete the old one. We
+then only need a pointer to this array, and an integer that tells us how
+much elements are in array.

+ * MAJOR CHANGES
+ *   Nov. 13, 1999	Takashi Iwai 
+ *     - Queues are allocated dynamically via ioctl.
+ *     - When owner client is deleted, all owned queues are deleted, too.
+ *     - Owner of unlocked queue is kept unmodified even if it is
+ *	 manipulated by other clients.
+ *     - Owner field in SET_QUEUE_OWNER ioctl must be identical with the
+ *       caller client.  i.e. Changing owner to a third client is not
+ *       allowed.
+ *
+ *  Aug. 30, 2000	Takashi Iwai
+ *     - Queues are managed in static array again, but with better way.
+ *       The API itself is identical.
+ *     - The queue is locked when queue_t pinter is returned via
+ *       queueptr().  This pointer *MUST* be released afterward by
+ *       queuefree(ptr).
+ *     - Addition of experimental sync support.

+ *      This driver is for the 'Mark Of The Unicorn' (MOTU)
+ *      MidiTimePiece AV multiport MIDI interface 
+ *
+ *      IOPORTS
+ *      -------
+ *      8 MIDI Ins and 8 MIDI outs
+ *      Video Sync In (BNC), Word Sync Out (BNC), 
+ *      ADAT Sync Out (DB9)
+ *      SMPTE in/out (1/4")
+ *      2 programmable pedal/footswitch inputs and 4 programmable MIDI controller knobs.
+ *      Macintosh RS422 serial port
+ *      RS422 "network" port for ganging multiple MTP's
+ *      PC Parallel Port ( which this driver currently uses )
+ *
+ *      MISC FEATURES
+ *      -------------
+ *      Hardware MIDI routing, merging, and filtering   
+ *      MIDI Synchronization to Video, ADAT, SMPTE and other Clock sources
+ *      128 'scene' memories, recallable from MIDI program change
+ *
+ *
+ * ChangeLog
+ * Jun 11 2001	Takashi Iwai 
+ *      - Recoded & debugged
+ *      - Added timer interrupt for midi outputs
+ *      - hwports is between 1 and 8, which specifies the number of hardware ports.
+ *        The three global ports, computer, adat and broadcast ports, are created
+ *        always after h/w and remote ports.

+ * After receiving a interrupt, it is important to indicate to the UART that
+ * this has been done. 
+ * For a Rx interrupt, this is done by reading the received byte.
+ * For a Tx interrupt this is done by either:
+ * a) Writing a byte
+ * b) Reading the IIR
+ * It is particularly important to read the IIR if a Tx interrupt is received
+ * when there is no data in tx_buff[], as in this case there no other
+ * indication that the interrupt has been serviced, and it remains outstanding
+ * indefinitely. This has the curious side effect that and no further interrupts
+ * will be generated from this device AT ALL!!.
+ * It is also desirable to clear outstanding interrupts when the device is
+ * opened/closed.
+ *
+ *
+ * Note that some devices need OUT2 to be set before they will generate
+ * interrupts at all. (Possibly tied to an internal pull-up on CTS?)

+ * VIRTUAL RAW MIDI DEVICE CARDS
+ *
+ * This dummy card contains up to 4 virtual rawmidi devices.
+ * They are not real rawmidi devices but just associated with sequencer
+ * clients, so that any input/output sources can be connected as a raw
+ * MIDI device arbitrary.
+ * Also, multiple access is allowed to a single rawmidi device.
+ *
+ * Typical usage is like following:
+ * - Load snd-virmidi module.
+ *	# modprobe snd-virmidi index=2
+ *   Then, sequencer clients 72:0 to 75:0 will be created, which are
+ *   mapped from /dev/snd/midiC1D0 to /dev/snd/midiC1D3, respectively.
+ *
+ * - Connect input/output via aconnect.
+ *	% aconnect 64:0 72:0	# keyboard input redirection 64:0 -> 72:0
+ *	% aconnect 72:0 65:0	# output device redirection 72:0 -> 65:0
+ *
+ * - Run application using a midi device (eg. /dev/snd/midiC1D0)

+ *
+ *  MPU401 and SPDIF are not supported yet.  I don't have the hardware
+ *  to aid in coding and testing, so I won't bother.

+ *  To quickly load the module,

+ *  modprobe -a snd-cmi8330 sbport=0x220 sbirq=5 sbdma8=1
+ *    sbdma16=5 wssport=0x530 wssirq=11 wssdma=0
+ *
+ *  This card has two mixers and two PCM devices.  I've cheesed it such
+ *  that recording and playback can be done through the same device.
+ *  The driver "magically" routes the capturing to the AD1848 codec,
+ *  and playback to the SB16 codec.  This allows for full-duplex mode
+ *  to some extent.
+ *  The utilities in alsa-utils are aware of both devices, so passing
+ *  the appropriate parameters to amixer and alsactl will give you
+ *  full control over both mixers.

+ * ES1869 NOTES:

+ * - there are a first full duplex pcm and a second playback only pcm

+ *
+ * - contrarily to some pages in DS_1869.PDF the rates can be set

+ *   using both channel for playback stereo 16 bit samples at 44100 Hz
+ *   the second pcm (Audio1) DMA slows down irregularly and sound is garbled.
+ *   
+ *   The same happens using Audio1 for captureing.
+ *
+ *   The Windows driver does not suffer of this (although it use Audio1
+ *   only for captureing). I'm unable to discover why.

+ *  Routines for control of 16-bit SoundBlaster cards and clones
+ *  Note: This is very ugly hardware which uses one 8-bit DMA channel and
+ *        second 16-bit DMA channel. Unfortunately 8-bit DMA channel can't
+ *        transfer 16-bit samples and 16-bit DMA channels can't transfer
+ *        8-bit samples. This make full duplex more complicated than
+ *        can be... People, don't buy these soundcards for full 16-bit
+ *        duplex!!!
+ *  Note: 16-bit wide is assigned to first direction which made request.
+ *        With full duplex - playback is preferred with abstract layer.
+ *
+ *  Note: Some chip revisions have hardware bug. Changing capture
+ *        channel from full-duplex 8bit DMA to 16bit DMA will block
+ *        16bit DMA transfers from DSP chip (capture) until 8bit transfer
+ *        to DSP chip (playback) starts. This bug can be avoided with
+ *        "16bit DMA Allocation" setting set to Playback or Capture.

+/* The low level driver for the WaveFront ICS2115 MIDI interface(s)
+ *
+ * Note that there is also an MPU-401 emulation (actually, a UART-401
+ * emulation) on the CS4232 on the Tropez and Tropez Plus. This code
+ * has nothing to do with that interface at all.
+ *
+ * The interface is essentially just a UART-401, but is has the
+ * interesting property of supporting what Turtle Beach called
+ * "Virtual MIDI" mode. In this mode, there are effectively *two*
+ * MIDI buses accessible via the interface, one that is routed
+ * solely to/from the external WaveFront synthesizer and the other
+ * corresponding to the pin/socket connector used to link external
+ * MIDI devices to the board.
+ *
+ * This driver fully supports this mode, allowing two distinct MIDI
+ * busses to be used completely independently, giving 32 channels of
+ * MIDI routing, 16 to the WaveFront synth and 16 to the external MIDI
+ * bus. The devices are named /dev/snd/midiCnD0 and /dev/snd/midiCnD1,
+ * where `n' is the card number. Note that the device numbers may be
+ * something other than 0 and 1 if the CS4232 UART/MPU-401 interface
+ * is enabled.
+ *
+ * Switching between the two is accomplished externally by the driver
+ * using the two otherwise unused MIDI bytes. See the code for more details.
+ *
+ * NOTE: VIRTUAL MIDI MODE IS ON BY DEFAULT (see lowlevel/isa/wavefront.c)
+ *
+ * The main reason to turn off Virtual MIDI mode is when you want to
+ * tightly couple the WaveFront synth with an external MIDI
+ * device. You won't be able to distinguish the source of any MIDI
+ * data except via SysEx ID, but thats probably OK, since for the most
+ * part, the WaveFront won't be sending any MIDI data at all.
+ *  
+ * The main reason to turn on Virtual MIDI Mode is to provide two
+ * completely independent 16-channel MIDI buses, one to the
+ * WaveFront and one to any external MIDI devices. Given the 32
+ * voice nature of the WaveFront, its pretty easy to find a use
+ * for all 16 channels driving just that synth.

+		   cannot be recovered without a complete reset and firmware
+		   reload of the ICS2115, which is a very expensive operation.
+
+		   So, doing things this way allows us to honor the notion of
+		   "RESETSAMPLES" reasonably cheaply. Note however, that this
+		   is done purely at user level: there is no WFB parser in
+		   this driver, and so a complete reset (back to General MIDI,
+		   or theoretically some other configuration) is the
+		   responsibility of the user level library. 
+
+		   To try to do this in the kernel would be a little
+		   crazy: we'd need 158K of kernel space just to hold
+		   a copy of the patch/program/sample header data.

+ *  card-als4000.c - driver for Avance Logic ALS4000 based soundcards.
+ *  Copyright (C) 2000 by Bart Hartgers ,
+ *			  Jaroslav Kysela 
+ *  Copyright (C) 2002 by Andreas Mohr 
+ *
+ *  Framework borrowed from Massimo Piccioni's card-als100.c.
+ *
+ * NOTES
+ *
+ *  Since Avance does not provide any meaningful documentation, and I
+ *  bought an ALS4000 based soundcard, I was forced to base this driver
+ *  on reverse engineering.
+ *
+ *  Note: this is no longer true. Pretty verbose chip docu (ALS4000a.PDF)
+ *  can be found on the ALSA web site.
+ *
+ *  The ALS4000 seems to be the PCI-cousin of the ALS100. It contains an
+ *  ALS100-like SB DSP/mixer, an OPL3 synth, a MPU401 and a gameport 
+ *  interface. These subsystems can be mapped into ISA io-port space, 
+ *  using the PCI-interface. In addition, the PCI-bit provides DMA and IRQ 
+ *  services to the subsystems.
+ * 
+ * While ALS4000 is very similar to a SoundBlaster, the differences in
+ * DMA and capturing require more changes to the SoundBlaster than
+ * desirable, so I made this separate driver.
+ * 
+ * The ALS4000 can do real full duplex playback/capture.
+ *
+ * FMDAC:
+ * - 0x4f -> port 0x14
+ * - port 0x15 |= 1
+ *
+ * Enable/disable 3D sound:
+ * - 0x50 -> port 0x14
+ * - change bit 6 (0x40) of port 0x15
+ *
+ * Set QSound:
+ * - 0xdb -> port 0x14
+ * - set port 0x15:
+ *   0x3e (mode 3), 0x3c (mode 2), 0x3a (mode 1), 0x38 (mode 0)
+ *
+ * Set KSound:
+ * - value -> some port 0x0c0d

+ *                   Abramo Bagnara 
+ *                   Cirrus Logic, Inc.
+ *  Routines for control of Cirrus Logic CS461x chips
+ *
+ *  KNOWN BUGS:
+ *    - Sometimes the SPDIF input DSP tasks get's unsynchronized
+ *      and the SPDIF get somewhat "distorcionated", or/and left right channel
+ *      are swapped. To get around this problem when it happens, mute and unmute 
+ *      the SPDIF input mixer controll.
+ *    - On the Hercules Game Theater XP the amplifier are sometimes turned
+ *      off on inadecuate moments which causes distorcions on sound.
+ *
+ *  TODO:
+ *    - Secondary CODEC on some soundcards
+ *    - SPDIF input support for other sample rates then 48khz
+ *    - Posibility to mix the SPDIF output with analog sources.
+ *    - PCM channels for Center and LFE on secondary codec
+ *
+ *  NOTE: with CONFIG_SND_CS46XX_NEW_DSP unset uses old DSP image (which
+ *        is default configuration), no SPDIF, no secondary codec, no
+ *        multi channel PCM.  But known to work.
+ *
+ *  FINALLY: A credit to the developers Tom and Jordan 
+ *           at Cirrus for have helping me out with the DSP, however we
+ *           still dont have sufficient documentation and technical
+ *           references to be able to implement all fancy feutures
+ *           supported by the cs46xx DSP's.

+  NOTES:
+  - Capture data is written unaligned starting from dma_base + 1 so I need to
+    disable mmap and to add a copy callback.
+  - After several cycle of the following:
+    while : ; do arecord -d1 -f cd -t raw | aplay -f cd ; done
+    a "playback write error (DMA or IRQ trouble?)" may happen.
+    This is due to playback interrupts not generated.
+    I suspect a timing issue.
+  - Sometimes the interrupt handler is invoked wrongly during playback.
+    This generates some harmless "Unexpected hw_pointer: wrong interrupt
+    acknowledge".
+    I've seen that using small period sizes.
+    Reproducible with:
+    mpg123 test.mp3 &
+    hdparm -t -T /dev/hda

+ *
+ *
+ *  Notes from Zach Brown about the driver code
+ *
+ *  Hardware Description
+ *
+ *	A working Maestro setup contains the Maestro chip wired to a 
+ *	codec or 2.  In the Maestro we have the APUs, the ASSP, and the
+ *	Wavecache.  The APUs can be though of as virtual audio routing
+ *	channels.  They can take data from a number of sources and perform
+ *	basic encodings of the data.  The wavecache is a storehouse for
+ *	PCM data.  Typically it deals with PCI and interracts with the
+ *	APUs.  The ASSP is a wacky DSP like device that ESS is loth
+ *	to release docs on.  Thankfully it isn't required on the Maestro
+ *	until you start doing insane things like FM emulation and surround
+ *	encoding.  The codecs are almost always AC-97 compliant codecs, 
+ *	but it appears that early Maestros may have had PT101 (an ESS
+ *	part?) wired to them.  The only real difference in the Maestro
+ *	families is external goop like docking capability, memory for
+ *	the ASSP, and initialization differences.
+ *
+ *  Driver Operation
+ *
+ *	We only drive the APU/Wavecache as typical DACs and drive the
+ *	mixers in the codecs.  There are 64 APUs.  We assign 6 to each
+ *	/dev/dsp? device.  2 channels for output, and 4 channels for
+ *	input.
+ *
+ *	Each APU can do a number of things, but we only really use
+ *	3 basic functions.  For playback we use them to convert PCM
+ *	data fetched over PCI by the wavecahche into analog data that
+ *	is handed to the codec.  One APU for mono, and a pair for stereo.
+ *	When in stereo, the combination of smarts in the APU and Wavecache
+ *	decide which wavecache gets the left or right channel.
+ *
+ *	For record we still use the old overly mono system.  For each in
+ *	coming channel the data comes in from the codec, through a 'input'
+ *	APU, through another rate converter APU, and then into memory via
+ *	the wavecache and PCI.  If its stereo, we mash it back into LRLR in
+ *	software.  The pass between the 2 APUs is supposedly what requires us
+ *	to have a 512 byte buffer sitting around in wavecache/memory.
+ *
+ *	The wavecache makes our life even more fun.  First off, it can
+ *	only address the first 28 bits of PCI address space, making it
+ *	useless on quite a few architectures.  Secondly, its insane.
+ *	It claims to fetch from 4 regions of PCI space, each 4 meg in length.
+ *	But that doesn't really work.  You can only use 1 region.  So all our
+ *	allocations have to be in 4meg of each other.  Booo.  Hiss.
+ *	So we have a module parameter, dsps_order, that is the order of
+ *	the number of dsps to provide.  All their buffer space is allocated
+ *	on open time.  The sonicvibes OSS routines we inherited really want
+ *	power of 2 buffers, so we have all those next to each other, then
+ *	512 byte regions for the recording wavecaches.  This ends up
+ *	wasting quite a bit of memory.  The only fixes I can see would be 
+ *	getting a kernel allocator that could work in zones, or figuring out
+ *	just how to coerce the WP into doing what we want.
+ *
+ *	The indirection of the various registers means we have to spinlock
+ *	nearly all register accesses.  We have the main register indirection
+ *	like the wave cache, maestro registers, etc.  Then we have beasts
+ *	like the APU interface that is indirect registers gotten at through
+ *	the main maestro indirection.  Ouch.  We spinlock around the actual
+ *	ports on a per card basis.  This means spinlock activity at each IO
+ *	operation, but the only IO operation clusters are in non critical 
+ *	paths and it makes the code far easier to follow.  Interrupts are
+ *	blocked while holding the locks because the int handler has to
+ *	get at some of them :(.  The mixer interface doesn't, however.
+ *	We also have an OSS state lock that is thrown around in a few
+ *	places.

+ * Note #1 "Sek'd models" ................................... martin 2002-12-07
+ * 
+ * Identical soundcards by Sek'd were labeled:
+ * RME Digi 32     = Sek'd Prodif 32
+ * RME Digi 32 Pro = Sek'd Prodif 96
+ * RME Digi 32/8   = Sek'd Prodif Gold
+ * 
+ * ****************************************************************************
+ * 
+ * Note #2 "full duplex mode" ............................... martin 2002-12-07
+ * 
+ * Full duplex doesn't work. All cards (32, 32/8, 32Pro) are working identical
+ * in this mode. Rec data and play data are using the same buffer therefore. At
+ * first you have got the playing bits in the buffer and then (after playing
+ * them) they were overwitten by the captured sound of the CS8412/14. Both 
+ * modes (play/record) are running harmonically hand in hand in the same buffer
+ * and you have only one start bit plus one interrupt bit to control this 
+ * paired action.
+ * This is opposite to the latter rme96 where playing and capturing is totally
+ * separated and so their full duplex mode is supported by alsa (using two 
+ * start bits and two interrupts for two different buffers). 
+ * But due to the wrong sequence of playing and capturing ALSA shows no solved
+ * full duplex support for the rme32 at the moment. That's bad, but I'm not
+ * able to solve it. Are you motivated enough to solve this problem now? Your
+ * patch would be welcome!

+    we need 2 contiguous 1.6MB regions for the board, it can be
+    a problem getting them once the system memory has become fairly
+    fragmented.

+ *   {linear volume, logarithmic attenuation equivalent}, ...
+ *
+ * Provides conversion from a linear half-volume value in the range
+ * [0,8192] to a logarithmic attenuation value in the range 0 to 6.02dB.
+ * Halving the linear volume is equivalent to an additional 6dB of 
+ * logarithmic attenuation. The algorithm used in log_from_linear()
+ * therefore uses this table as follows:
+ * 
+ * - loop and for every time the volume is less than half the maximum 
+ *   volume (16384), add another 6dB and halve the maximum value used
+ *   for this comparison.
+ * - when the volume is greater than half the maximum volume, take
+ *   the difference of the volume to half volume (in the range [0,8192])
+ *   and look up the log_table[] to find the nearest entry.
+ * - take the logarithic component of this entry and add it to the 
+ *   resulting attenuation.
+ *
+ * Thus this routine provides a linear->log conversion for a range of
+ * [0,16384] using only 386 table entries
+ *
+ * Note: although this table stores log attenuation in 8.8 format, values
+ * were only calculated for 6 bits fractional precision, since that is
+ * the most precision offered by the trident hardware.

+ * Changes:
+ *
+ * Dec. 19, 2002	Takashi Iwai 
+ *	- use the DSX channels for the first pcm playback.
+ *	  (on VIA8233, 8233C and 8235 only)
+ *	  this will allow you play simultaneously up to 4 streams.
+ *	  multi-channel playback is assigned to the second device
+ *	  on these chips.
+ *	- support the secondary capture (on VIA8233/C,8235)
+ *	- SPDIF support
+ *	  the DSX3 channel can be used for SPDIF output.
+ *	  on VIA8233A, this channel is assigned to the second pcm
+ *	  playback.
+ *	  the card config of alsa-lib will assign the correct
+ *	  device for applications.
+ *	- clean up the code, separate low-level initialization
+ *	  routines for each chipset.

+ *	Sound core handling. Breaks out sound functions to submodules

+ *
+ *                         --------------------
+ * 
+ *	Top level handler for the sound subsystem. Various devices can
+ *	plug into this. The fact they don't all go via OSS doesn't mean 
+ *	they don't have to implement the OSS API. There is a lot of logic
+ *	to keeping much of the OSS weight out of the code in a compatibility
+ *	module, but it's up to the driver to rember to load it...
+ *
+ *	The code provides a set of functions for registration of devices
+ *	by type. This is done rather than providing a single call so that
+ *	we can hide any future changes in the internals (eg when we go to
+ *	32bit dev_t) from the modules and their interface.
+ *
+ *	Secondly we need to allocate the dsp, dsp16 and audio devices as
+ *	one. Thus we misuse the chains a bit to simplify this.
+ *
+ *	Thirdly to make it more fun and for 2.3.x and above we do all
+ *	of this using fine grained locking.
+ *
+ *	FIXME: we have to resolve modules and fine grained load/unload
+ *	locking at some point in 2.3.x.

+ * Copyright (C) 1996,1997 Thomas K. Dyas (tdyas@eden.rutgers.edu)
+ *
+ * --- Notes from Thomas's original driver ---
+ * This is the lowlevel driver for the AMD7930 audio chip found on all
+ * sun4c machines and some sun4m machines.
+ *
+ * The amd7930 is actually an ISDN chip which has a very simple
+ * integrated audio encoder/decoder. When Sun decided on what chip to
+ * use for audio, they had the brilliant idea of using the amd7930 and
+ * only connecting the audio encoder/decoder pins.
+ *
+ * Thanks to the AMD engineer who was able to get us the AMD79C30
+ * databook which has all the programming information and gain tables.
+ *
+ * Advanced Micro Devices' Am79C30A is an ISDN/audio chip used in the
+ * SparcStation 1+.  The chip provides microphone and speaker interfaces
+ * which provide mono-channel audio at 8K samples per second via either
+ * 8-bit A-law or 8-bit mu-law encoding.  Also, the chip features an
+ * ISDN BRI Line Interface Unit (LIU), I.430 S/T physical interface,
+ * which performs basic D channel LAPD processing and provides raw
+ * B channel data.  The digital audio channel, the two ISDN B channels,
+ * and two 64 Kbps channels to the microprocessor are all interconnected
+ * via a multiplexer.
