* Driver CA0106 chips. e.g. Sound Blaster Audigy LS and Live 24bit
* Version: 0.0.25
*
* FEATURES currently supported:
* Front, Rear and Center/LFE.
* Surround40 and Surround51.
* Capture from MIC an LINE IN input.
* SPDIF digital playback of PCM stereo and AC3/DTS works.
* (One can use a standard mono mini-jack to one RCA plugs cable.
* or one can use a standard stereo mini-jack to two RCA plugs cable.
* Plug one of the RCA plugs into the Coax input of the external decoder/receiver.)
* ( In theory one could output 3 different AC3 streams at once, to 3 different SPDIF outputs. )
* Notes on how to capture sound:
* The AC97 is used in the PLAYBACK direction.
* The output from the AC97 chip, instead of reaching the speakers, is fed into the Philips 1361T ADC.
* So, to record from the MIC, set the MIC Playback volume to max,
* unmute the MIC and turn up the MASTER Playback volume.
* So, to prevent feedback when capturing, minimise the "Capture feedback into Playback" volume.
*
* The only playback controls that currently do anything are: -
* Analog Front
* Analog Rear
* Analog Center/LFE
* SPDIF Front
* SPDIF Rear
* SPDIF Center/LFE
*
* For capture from Mic in or Line in.
* Digital/Analog ( switch must be in Analog mode for CAPTURE. )
*
* CAPTURE feedback into PLAYBACK
*
* Changelog:
* Support interrupts per period.
* Removed noise from Center/LFE channel when in Analog mode.
* Rename and remove mixer controls.
* 0.0.6
* Use separate card based DMA buffer for periods table list.
* 0.0.7
* Change remove and rename ctrls into lists.
* 0.0.8
* Try to fix capture sources.
* 0.0.9
* Fix AC3 output.
* Enable S32_LE format support.
* 0.0.10
* Enable playback 48000 and 96000 rates. (Rates other that these do not work, even with "plug:front".)
* 0.0.11
* Add Model name recognition.
* 0.0.12
* Correct interrupt timing. interrupt at end of period, instead of in the middle of a playback period.
* Remove redundent "voice" handling.
* 0.0.13
* Single trigger call for multi channels.
* 0.0.14
* Set limits based on what the sound card hardware can do.
* playback periods_min=2, periods_max=8
* capture hw constraints require period_size = n * 64 bytes.
* playback hw constraints require period_size = n * 64 bytes.
* 0.0.15
* Minor updates.
* 0.0.16
* Implement 192000 sample rate.
* 0.0.17
* Add support for SB0410 and SB0413.
* 0.0.18
* Modified Copyright message.
* 0.0.19
* Finally fix support for SB Live 24 bit. SB0410 and SB0413.
* The output codec needs resetting, otherwise all output is muted.
* 0.0.20
* Merge "pci_disable_device(pci);" fixes.
* 0.0.21
* Add 4 capture channels. (SPDIF only comes in on channel 0. )
* Add SPDIF capture using optional digital I/O module for SB Live 24bit. (Analog capture does not yet work.)
* 0.0.22
* Add support for MSI K8N Diamond Motherboard with onboard SB Live 24bit without AC97. From kiksen, bug #901
* 0.0.23
* Implement support for Line-in capture on SB Live 24bit.
* 0.0.24
* Add support for mute control on SB Live 24bit (cards w/ SPI DAC)
* 0.0.25
* Powerdown SPI DAC channels when not in use
*
* BUGS:
* Some stability problems when unloading the snd-ca0106 kernel module.
* --

* TODO:
* 4 Capture channels, only one implemented so far.
* Other capture rates apart from 48khz not implemented.

* 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 control.
* - 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 don't have sufficient documentation and technical
* references to be able to implement all fancy feutures
* supported by the cs46xx DSP's.

* Virtual ALSA driver for PCM testing/fuzzing
*
* Copyright 2023 Ivan Orlov <[email protected]>
*
* This is a simple virtual ALSA driver, which can be used for audio applications/PCM middle layer
* testing or fuzzing.
* It can:
* - Simulate 'playback' and 'capture' actions
* - Generate random or pattern-based capture data
* - Check playback buffer for containing looped template, and notify about the results
* through the debugfs entry
* - Inject delays into the playback and capturing processes. See 'inject_delay' parameter.
* - Inject errors during the PCM callbacks.
* - Register custom RESET ioctl and notify when it is called through the debugfs entry
* - Work in interleaved and non-interleaved modes
* - Support up to 8 substreams
* - Support up to 4 channels
* - Support framerates from 8 kHz to 48 kHz
*
* When driver works in the capture mode with multiple channels, it duplicates the looped
* pattern to each separate channel. For example, if we have 2 channels, format = U8, interleaved
* access mode and pattern 'abacaba', the DMA buffer will look like aabbccaabbaaaa..., so buffer for
* each channel will contain abacabaabacaba... Same for the non-interleaved mode.
*
* However, it may break the capturing on the higher framerates with small period size, so it is
* better to choose larger period sizes.
*
* You can find the corresponding selftest in the 'alsa' selftests folder.

* MOTU Midi Timepiece ALSA Main routines
* Copyright by Michael T. Mayers (c) Jan 09, 2000
* mail: [email protected]
* Thanks to John Galbraith
*
* 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 <[email protected]>
* - 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.

/* NOTES ON SERVICING INTERUPTS
* ---------------------------
* 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)

* STRATEGY
* for playback, we send series of "chunks", which size is equal with the
* IBL size, typically 126 samples. at each end of chunk, the end-of-buffer
* interrupt is notified, and the interrupt handler will feed the next chunk.
*
* the current position is calculated from the sample count RMH.
* pipe->transferred is the counter of data which has been already transferred.
* if this counter reaches to the period size, snd_pcm_period_elapsed() will
* be issued.
*
* for capture, the situation is much easier.
* to get a low latency response, we'll check the capture streams at each
* interrupt (capture stream has no EOB notification). if the pending
* data is accumulated to the period size, snd_pcm_period_elapsed() is
* called and the pointer is updated.
*
* the current point of read buffer is kept in pipe->hw_ptr. note that
* this is in bytes.
*
* TODO
* - linked trigger for full-duplex mode.
* - scheduled action on the stream.

* ALSA sequencer device management

*----------------------------------------------------------------
*
* This device handler separates the card driver module from sequencer
* stuff (sequencer core, synth drivers, etc), so that user can avoid
* 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.
