ASoC: sof: Standardize ASoC menu

2025-06-24T00:01:18+00:00

Current Kconfig menu at [ALSA for SoC audio support] has no rules. So, some venders are using menu style, some venders are listed each drivers on top page, etc. It is difficult to find target vender and/or drivers because it is very random. Let's standardize ASoC menu Signed-off-by: Kuninori Morimoto Link: https://patch.msgid.link/87o6utzqef.wl-kuninori.morimoto.gx@renesas.com Acked-by: Peter Ujfalusi Signed-off-by: Mark Brown

ASoC: SOF: core: Implement IPC version fallback if firmware files are missing

2023-11-29T13:25:15+00:00

If a firmware file is missing for the selected IPC type then try to switch to other supported IPC type and check if that one can be used instead. If for example a platform is changed to IPC4 as default version but the given machine does not yet have the needed topology file created then we will fall back to IPC3 which should have all the needed files. Relocate the sof_init_environment() to be done at a later phase, in sof_probe_continue(). This will only have changes in behavior if CONFIG_SND_SOC_SOF_PROBE_WORK_QUEUE is enabled (Intel HDA platforms) by not failing the module probe, but it is not going to be different case compared to for example failed firmware booting or topology loading error.

ASoC: SOF: Drop obsolete dependency on COMPILE_TEST

2022-11-28T13:04:35+00:00

Since commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), it is possible to test-build any driver which depends on OF on any architecture by explicitly selecting OF. Therefore depending on COMPILE_TEST as an alternative is no longer needed.

ASoC: SOF: introduce new DEBUG_NOCODEC mode

2022-10-28T12:05:01+00:00

The existing NOCODEC mode enforces a build-time mutual exclusion with the HDaudio link support, mostly to avoid any dependency on the snd_hdac library and references to HDAudio codec/i915 stuff. This is very useful to track dependencies and test a minimal configuration, but very painful for developers and CI: a recompilation and reinstall of the kernel modules is required. This patch suggests an alternate middle ground where the selection of the machine driver and all codec-related actions are bypassed at run-time, contingent on a kernel module parameter being set. For example setting BIT(10) with 'options snd_sof sof_debug=0x401' is enough to switch from an HDaudio card to a nocodec one. This new DEBUG_NOCODEC mode is not suitable for distributions and end-users. It's not even recommended on all platforms, i.e. the NOCODEC mode is known not to work on specific devices where the BIOS did not configure support for I2S/DMIC interfaces. The usual development devices such as Chromebooks, Up boards and Intel RVP are the only recommended platforms where this mode can be supported. Note that the dynamic switch between HDaudio and nocodec may not always possible depending on hardware layout, pin-mux options, and BIOS settings. The audio subsustems on Intel platforms has to support 4 types of interfaces and pin-mux can be complicated. Reviewers might ask: why didn't we do this earlier? The main reason is that all the codec-related configurations were not cleanly separated out in the sof/intel directory. With all the cleanups done recently, adding this opt-in behavior is relatively straightforward. Tested on UpExtreme (WHL) and UpExtreme i11 (TGL).

ASoC: SOF: Compile and runtime IPC version selection

2022-06-14T10:22:12+00:00

The new IPC4 version is only supported by Intel platforms, iMX, AMD and MediaTek only uses the standard SOF IPC. There is no need for these platforms to build kernel support for IPC4 as it is just dead code for them. SND_SOC_SOF_IPC3 and SND_SOC_SOF_INTEL_IPC4 is introduced to allow compile time selection and exclusion of IPC implementations. To avoid randconfig failures add also support for runtime selection of the IPC ops in ipc.c based on sdev->pdata->ipc_type Signed-off-by: Peter Ujfalusi Reviewed-by: Bard Liao Reviewed-by: Ranjani Sridharan Link: https://lore.kernel.org/r/20220614075618.28605-1-peter.ujfalusi@linux.intel.com Signed-off-by: Mark Brown

ASoC: SOF: Convert the generic probe support to SOF client

2022-02-10T15:19:12+00:00

Add a new client driver for probes support and move all the probes-related code from the core to the client driver. The probes client driver registers a component driver with one CPU DAI driver for extraction and creates a new sound card with one DUMMY DAI link with a dummy codec that will be used for extracting audio data from specific points in the audio pipeline. The probes debugfs ops are based on the initial implementation by Cezary Rojewski and have been moved out of the SOF core into the client driver making it easier to maintain. This change will make it easier for the probes functionality to be added for all platforms without having the need to modify the existing(15+) machine drivers.
