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.

ASoC: soc-dapm: add snd_soc_dapm_alloc()

2026-01-26T11:44:45+00:00

Because struct snd_soc_dapm_context is soc-dapm framework specific, user driver don't need to access its member directly, we would like to hide them. struct snd_soc_dapm_context will be removed from header in the future. Current card/component are using dapm_context instance. But it will be moved to soc-dapm.c, and we can use will be only pointer. Makes it to pointer.

Merge tag 'asoc-v6.18' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next

2025-09-20T06:38:17+00:00

ASoC: Updates for v6.18 A relatively quiet release for ASoC, we've had a lot of maintainance work going on and several new drivers but really the most remarkable thing is that we removed a driver, the WL1273 driver used in some old Nokia systems that have had the underlying system support removed from the kernel. - Morimoto-san continues his work on cleanups of the core APIs and enforcement of abstraction layers. - Lots of cleanups and conversions of DT bindings. - Substantial maintainance work on the Intel AVS drivers. - Support for Qualcomm Glymur and PM4125, Realtek RT1321, Shanghai FourSemi FS2104/5S, Texas Instruments PCM1754. - Remove support for TI WL1273.

ASoC: soc-component: add snd_soc_component_to_dapm()

2025-09-18T21:24:12+00:00

Because struct snd_soc_dapm_context is soc-dapm framework specific, user driver don't need to access its member directly, we would like to hide them. struct snd_soc_dapm_context will be removed from header in the future. Current dapm of card/component are using "instance", but it will be "pointer" if snd_soc_dapm_context was removed from header. snd_soc_component_to_dapm() is needed to switch to the new style while maintaining compatibility Signed-off-by: Kuninori Morimoto Link: https://patch.msgid.link/878qiux06m.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown

ASoC: soc-dapm: use dapm->component instead of container_of()

2025-09-18T21:24:11+00:00

Because struct snd_soc_dapm_context is soc-dapm framework specific, user driver don't need to access its member directly, we would like to hide them. struct snd_soc_dapm_context will be removed from header in the future. Now, snd_soc_dapm_to_component() (A) will convert dapm to component by container_of() (a). (A) static inline struct snd_soc_component *snd_soc_dapm_to_component( struct snd_soc_dapm_context *dapm) { (a) return container_of(dapm, struct snd_soc_component, dapm); } dapm of component works, but dapm of card will be "unknown" pointer (= not NULL), because (a) is using "container_of()". OTOH, ASoC will call snd_soc_dapm_init() (X) to initialize dapm, and it will be called from snd_soc_bind_card() (p) (for card) or soc_probe_component() (q) (for component) with component pointer. (p) static int snd_soc_bind_card(...) { ... (X) snd_soc_dapm_init(..., NULL); ... ^^^^ } (q) static int soc_probe_component(...) { ... (X) snd_soc_dapm_init(..., component); ... ^^^^^^^^^ } And snd_soc_dapm_init() (X) will fill dapm->component (x) (X) void snd_soc_dapm_init(..., component, ...) { ... (x) dapm->component = component; ... } We can simply use dapm->component in snd_soc_dapm_to_component() (A). In this case, dapm of card (p) will be just NULL. Use dapm->component instead of container_of(). The picky note can be removed by this patch.

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: soc-dapm: rename snd_soc_kcontrol_component() to snd_soc_kcontrol_to_component()

2025-09-01T12:37:59+00:00

We have 2 similar functions, both converts date from snd_kcontrol to snd_soc_component. (A) snd_soc_kcontrol_component() (B) snd_soc_dapm_kcontrol_component() (A) is just wrapper for snd_kcontrol_chip(). (B) is for more complex conversion. Having similar functions is confusable. So (A) will be replaced to original snd_kcontrol_chip(). (B) will be stay, but the function name should be xx_to_xx(). And it is defined at soc-component.h. It should be implemented at soc-dapm.c. This patch renames it to snd_soc_dapm_kcontrol_to_component(), and move to soc-dapm.c. This patch keeps compatible by using define, but old name will be replaced on each drivers and removed from ASoC in the future.
