ASoC: soc-component: re-add pcm_new()/pcm_free()

2026-05-23T11:08:54+00:00

[ Upstream commit 68130eef1e0d3c1770952e738f7f8d9f340bd42d ]

Because old pcm_new()/pcm_free() didn't care about parameter component,
to avoid name collisions, we have added pcm_construct()/pcm_destruct() by
commit c64bfc9066007 ("ASoC: soc-core: add new pcm_construct/pcm_destruct")

Because all driver switch to new pcm_construct()/pcm_destruct(), old
pcm_new()/pcm_free() were remoted by commit e9067bb502787 ("ASoC:
soc-component: remove snd_pcm_ops from component driver")

But naming of pcm_construct()/pcm_destruct() are not goot. re-add
pcm_new()/pcm_free(), and switch to use it, again.

Now no one is using snd_soc_component_xxx() wrapper for dapm.
Remove it.

ALSA: compress_offload: Add 64-bit safe timestamp infrastructure

2025-09-08T07:33:24+00:00

The copied_total field in struct snd_compr_tstamp is a 32-bit
value that can overflow on long-running high-bitrate streams,
leading to incorrect calculations for buffer availablility.

This patch adds a 64-bit safe timestamping mechanism.
A new UAPI struct, snd_compr_tstamp64, is added which uses 64-bit
types for byte counters. The relevant ops structures across the
ASoC and core compress code are updated to use this new struct.
ASoC drivers are updated to use u64 counters.

Internal timestamps being u64 now, a compatibility function is added
to convert the 64-bit timestamp back to the 32-bit format for legacy
ioctl callers.

ASoC: component: Remove redundant pm_runtime_mark_last_busy() calls

2025-07-04T18:28:21+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: add common snd_soc_ret() and use it

2025-02-06T17:26:18+00:00

Each soc-xxx.c is using own snd_xxx_ret(), but we want to share it.
Let's add common snd_soc_ret() for it.

ASoC: remove unused substream in macro soc_component_mark_pop

2024-09-29T23:09:52+00:00

The soc_component_mark_pop don't need substream, and also
substream is not used in this macro, so we can remove it.
This is detected by macro_checker.py script.

ASoC: Drop snd_soc_*_get_kcontrol_locked()

2024-08-09T12:24:55+00:00

The recent cleanup in ALSA control core made no difference between
snd_ctl_find_id_mixer() and snd_ctl_find_id_mixer_locked(), and the
latter is to be dropped.  The only user of the left API was ASoC, and
that's snd_soc_card_get_kcontrol_locked() and
snd_soc_component_get_kcontrol_locked().

This patch drops those functions and rewrites those users to call the
variant without locked instead.  The test of the API became
superfluous, hence dropped as well.

As all callers of snd_ctl_find_id_mixer_locked() are gone,
snd_ctl_find_id_mixer_locked() is finally dropped, too.

ASoC: soc-component: Add new snd_soc_component_get_kcontrol() helpers

2024-08-02T13:04:39+00:00

Add new helper functions snd_soc_component_get_kcontrol() and
snd_soc_component_get_kcontrol_locked() that returns a kcontrol
by name, but will factor in the components name_prefix, to handle
situations where multiple components are present with the same
controls.

ASoC: soc-dapm: Add helper for comparing widget name

2023-10-09T12:03:28+00:00

Some drivers use one event callback for multiple widgets but still need
to perform a bit different actions based on actual widget.  This is done
by comparing widget name, however drivers tend to miss possible name
prefix.  Add a helper to solve common mistakes.
