ASoC: SOF: pcm: Set the PCM device name for HDMI

2025-10-29T20:14:43+00:00

User space (alsa-lib) uses the PCM device name to detect HDMI devices, the name is expected to be in form of 'HDMI'++number. The PCM device name is not configured in ASoC, only the PCM id is set based on the loaded topology. Detect the HDMI PCM playback devices and configure the name to help user space to handle HDMI PCMs correctly. aplay -l | grep HDMI (Audio capable monitor connected) Before the change: card 0: sofhdadsp [sof-hda-dsp], device 3: HDMI1 (*) [] card 0: sofhdadsp [sof-hda-dsp], device 4: HDMI2 (*) [] card 0: sofhdadsp [sof-hda-dsp], device 5: HDMI3 (*) [] after the change: card 0: sofhdadsp [sof-hda-dsp], device 3: HDMI1 (*) [DELL P1917S] card 0: sofhdadsp [sof-hda-dsp], device 4: HDMI2 (*) [HDMI 2] card 0: sofhdadsp [sof-hda-dsp], device 5: HDMI3 (*) [HDMI 3] Signed-off-by: Peter Ujfalusi Reviewed-by: Bard Liao Reviewed-by: Kai Vehmanen Reviewed-by: Ranjani Sridharan Link: https://patch.msgid.link/20251029105134.1342-1-peter.ujfalusi@linux.intel.com Signed-off-by: Mark Brown

treewide: Remove redundant

2025-07-04T21:42:36+00:00

Merge series from Sakari Ailus : Late last year I posted a set to switch to __pm_runtime_mark_last_busy() and gradually get rid of explicit pm_runtime_mark_last_busy() calls in drivers, embedding them in the appropriate pm_runtime_*autosuspend*() calls. The overall feedback I got at the time was that this is an unnecessary intermediate step, and removing the pm_runtime_mark_last_busy() calls can be done after adding them to the relevant Runtime PM autosuspend related functions.

ASoC: SOF: Remove redundant pm_runtime_mark_last_busy() calls

2025-07-04T18:28:22+00:00

pm_runtime_put_autosuspend(), pm_runtime_put_sync_autosuspend(), pm_runtime_autosuspend() and pm_request_autosuspend() now include a call to pm_runtime_mark_last_busy(). Remove the now-reduntant explicit call to pm_runtime_mark_last_busy().

ASoC: SOF: pcm: Reverse check for prepared stream in sof_pcm_hw_params()

2025-06-19T23:21:16+00:00

Reduce the number of checks needed with the simple and most common audio sequence when the stream is started then stopped. If the stream has not been prepared there is no need to check if we have pcm_ops and pcm_ops->hw_free() callback as it does not matter.

ASoC: Merge up fixes

Merge branch 'for-6.14' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into asoc-6.15 to avoid a bunch of add/add conflicts.

ASoC: SOF: pcm: Add snd_sof_pcm specific wrappers for dev_dbg() and dev_err()

2025-02-06T11:25:43+00:00

Introduce spcm_dbg() and spcm_err() macros to provide consistent printing for debug and error messages which includes usable information in the print's prefix. Update the prints in pcm.c, ipc3-pcm.c and ipc4-pcm.c to take advantage of the features provided by the macros.

The platform specific pcm_open call via snd_sof_pcm_platform_open() can modify the initial buffer configuration via constraints. Move the prints as last step in the sof_pcm_open() function to reflect the final setup.

ASoC: SOF: Relocate and rework functionality for PCM stream freeing

2025-02-06T11:25:41+00:00

Move the sof_pcm_stream_free() from sof-audio.c to pcm.c as static function and add wrapper to free all active stream, which is going to be used in ipc3/4 topology code (removes duplicated code). With this change most of the PCM stream related code is located in one source file for easier lookup and simplified flow.

ASoC: SOF: pcm: Clear the susbstream pointer to NULL on close

2025-02-05T14:06:27+00:00

The spcm->stream[substream->stream].substream is set during open and was left untouched. After the first PCM stream it will never be NULL and we have code which checks for substream NULLity as indication if the stream is active or not. For the compressed cstream pointer the same has been done, this change will correct the handling of PCM streams.
