- * 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.

   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.

+ * 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.

- * - Don't wonder about some strange implementations of things - especially the
- * (heavy) shadowing of codec registers, with which I tried to reduce read
- * accesses to a minimum, because after a variable amount of accesses, the AC97
- * controller doesn't raise the register access finished bit anymore ...
- *

+ * Copyright 2023 Ivan Orlov <ivan.orlov0322@gmail.com>
+ *
+ * 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.

+ * entry within the 0x190000 range, and when a range of entries is in use, the
+ * ending value is overwritten with 0xff.
+ * 0x1578 in exram is a table of 0x25 entries, corresponding to the ChipIO
+ * streamID's, where each entry is a starting 0x190000 port offset.
+ * 0x159d in exram is the same as 0x1578, except it contains the ending port
+ * offset for the corresponding streamID.

+ * On certain cards, such as the SBZ/ZxR/AE7, these are originally setup by
+ * the 8051, then manually overwritten to remap the ports to work with the
+ * new DACs.
+ *
+ * Currently known portID's:
+ * 0x00-0x1f: HDA audio stream input/output ports.
+ * 0x80-0xbf: Sample rate converter input/outputs. Only valid ports seem to
+ *            have the lower-nibble set to 0x1, 0x2, and 0x9.
+ * 0xc0-0xdf: DSP DMA input/output ports. Dynamically assigned.
+ * 0xe0-0xff: DAC/ADC audio input/output ports.
+ *
+ * Currently known streamID's:
+ * 0x03: Mic1 ADC to DSP.
+ * 0x04: Mic2 ADC to DSP.
+ * 0x05: HDA node 0x02 audio stream to DSP.
+ * 0x0f: DSP Mic exit to HDA node 0x07.
+ * 0x0c: DSP processed audio to DACs.
+ * 0x14: DAC0, front L/R.
+ *
+ * It is possible to route the HDA audio streams directly to the DAC and
+ * bypass the DSP entirely, with the only downside being that since the DSP

+ * 6. At high temperature (TA > +85°C), the digital supply current (IVD)
+ * may be excessive (up to an additional 200 μA), which is most easily
+ * observed while the part is being held in reset (RESET# active low).
+ *
+ * Root Cause: At initial powerup of the device, the logic that drives
+ * the clock and write enable to the S/PDIF SRC RAMs is not properly
+ * initialized.
+ * Certain random patterns will cause a steady leakage current in those
+ * RAM cells. The issue will resolve once the SRCs are used (turned on).
+ *
+ * Workaround: The following verb sequence briefly turns on the S/PDIF SRC
+ * blocks, which will alleviate the issue.
