firmware: cs_dsp: Add mock bin file generator for KUnit testing

2024-12-13T13:14:40+00:00

Add a mock firmware file that emulates what the firmware build tools
would normally create. This will be used by KUnit tests to generate a
test bin file.

The data payload in a bin is an opaque blob, so the mock bin only needs
to generate the appropriate file header and description block for each
payload blob.

firmware: cs_dsp: Add mock DSP memory map for KUnit testing

2024-12-13T13:14:38+00:00

Add helper functions to implement an emulation of the DSP memory map.

There are three main groups of functionality:

1. Define a mock cs_dsp_region table.
2. Calculate the addresses of memory and algorithms from the firmware
   header in XM.
3. Build a mock XM header in emulated XM.

firmware: cs_dsp: Add mock regmap for KUnit testing

2024-12-13T13:14:37+00:00

Add a mock regmap implementation to act as a simulated DSP for KUnit
testing. This is built as a utility module so that it could be used by
clients of cs_dsp to create a mock "DSP" for their own testing.

cs_dsp interacts with the DSP only through registers. Most of the
register space of the DSP is RAM. ADSP cores have a small set of control
registers. HALO Core DSPs have a much larger set of control registers but
only a small subset are used.

Most writes are "blind" in the sense that cs_dsp does not expect to
receive any sort of response from the DSP. So there isn't any need to
emulate a "DSP", only a set of registers that can be written and read
back.

The idea of the mock regmap is to use the cache to accumulate writes
which can then be tested against the values that are expected to be in
the registers.

Stray writes can be detected by dropping the cache entries for all
addresses that should have been written and then issuing a regcache_sync().
If this causes bus writes it means there were writes to unexpected
registers.

Merge tag 'sound-6.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

2024-07-19T19:39:34+00:00

Pull sound updates from Takashi Iwai:
 "Lots of changes in this cycle, but mostly for cleanups and
  refactoring.

  Significant amount of changes are about DT schema conversions for ASoC
  at this time while we see other usual suspects, too.

  Some highlights below:

  Core:
   - Re-introduction of PCM sync ID support API
   - MIDI2 time-base extension in ALSA sequencer API

  ASoC:
   - Syncing of features between simple-audio-card and the two
     audio-graph cards
   - Support for specifying the order of operations for components
     within cards to allow quirking for unusual systems
   - Lots of DT schema conversions
   - Continued SOF/Intel updates for topology, SoundWire, IPC3/4
   - New support for Asahi Kasei AK4619, Cirrus Logic CS530x, Everest
     Semiconductors ES8311, NXP i.MX95 and LPC32xx, Qualcomm LPASS v2.5
     and WCD937x, Realtek RT1318 and RT1320 and Texas Instruments
     PCM5242

  HD-audio:
   - More quirks, Intel PantherLake support, senarytech codec support
   - Refactoring of Cirrus codec component-binding

  Others:
   - ALSA control kselftest improvements, and fixes for input value
     checks in various drivers"

firmware: cs_dsp: Rename fw_ver to wmfw_ver

2024-07-10T17:45:05+00:00

Rename the confusingly named struct member fw_ver to wmfw_ver. It
contains the wmfw format version of the loaded wmfw file.

This commit also contains an update to wm_adsp for the new name.

firmware: cs_dsp: Add write sequence interface

2024-06-28T14:35:57+00:00

A write sequence is a sequence of register addresses
and values executed by some Cirrus DSPs following
certain power state transitions.

Add support for Cirrus drivers to update or add to a
write sequence present in firmware.

ALSA: cirrus: Tidy up of firmware control read/write

2024-04-03T19:45:32+00:00

Merge series from Richard Fitzgerald :

This set of patches factors out some repeated code to clean up
firmware control read/write functions, and removes some redundant
control notification code.

firmware: cs_dsp: Add locked wrappers for coeff read and write

2024-04-03T15:10:27+00:00

It is a common pattern for functions to take and release the DSP
pwr_lock over the cs_dsp calls to read and write firmware controls.
Add wrapper functions to do this sequence so that the calling code can
be simplified to a single function call..
