ASoC: add soc-component.c ALSA SoC has many snd_soc_component_xxx(), but these are randomly located in many files. Because of it, code is difficult to read. This patch creates new soc-component.c, and moves existing snd_soc_component_xxx() into it. But not yet fully. We need more cleanup it.

But runtime->delay might be overwrote if it adjusted to multiple components in the future. 3) Component delay is updated at .pointer callback timing (secretly).

ASoC: soc-core: add debugfs_prefix member to snd_soc_component_driver Allow the component debugfs_prefix to be set from snd_soc_component_driver. First use case is avoiding a duplicate debugfs entry error in case a device has multiple components which have the same name therefore. Note that we don't set component->debugfs_prefix if it's set already. That's needed because partially component->debugfs_prefix is set before calling snd_soc_component_initialize().

This kind of duplicated code can be a hotbed of bugs, thus, we want to share soc_pcm_close() and rollback.

The idea of having bit-flag or counter is not enough for this purpose. For example if one DAI is used for 2xPlaybacks for some reasons, and if 1st Playback was succeeded but 2nd Playback was failed, 2nd Playback rollback doesn't need to call shutdown. But it has succeeded bit-flag or counter via 1st Playback, thus, 2nd Playback rollback will call unneeded shutdown. And 1st Playback's necessary shutdown will not be called, because bit-flag or counter was cleared by wrong 2nd Playback rollback. To avoid such case, this patch marks substream pointer when open() was succeeded. If rollback needed, it will check rollback flag and marked substream pointer. One note here is that it cares *current* open() only now. but we might want to check *whole* marked substream in the future. This patch is using macro named "push/pop", so that it can be easily update.

/* component IO */
ASoC: soc-component: merge snd_soc_component_read() and snd_soc_component_read32() We had read/write function for Codec, Platform, etc, but these has been merged into snd_soc_component_read/write(). Internally, it is using regmap or driver function. In read case, each styles are like below regmap ret = regmap_read(..., reg, &val); driver function val = xxx->read(..., reg); Because of this kind of different style, to keep same read style, when we merged each read function into snd_soc_component_read(), we created snd_soc_component_read32(), like below. commit 738b49efe6c6 ("ASoC: add snd_soc_component_read32") (1) val = snd_soc_component_read32(component, reg); (2) ret = snd_soc_component_read(component, reg, &val); Many drivers are using snd_soc_component_read32(), and some drivers are using snd_soc_component_read() today. In generally, we don't check read function successes, because, we will have many other issues at initial timing if read function didn't work. Now we can use soc_component_err() when error case. This means, it is easy to notice if error occurred. This patch aggressively merge snd_soc_component_read() and _read32(), and makes snd_soc_component_read/write() as generally style. This patch do 1) merge snd_soc_component_read() and snd_soc_component_read32() 2) it uses soc_component_err() when error case (easy to notice) 3) keeps read32 for now by #define 4) update snd_soc_component_read() for all drivers Because _read() user drivers are not too many, this patch changes all user drivers.

ASoC: soc-component: add snd_soc_component_read/write_field() It's often the case that we would write or read a particular field in register. With the current soc_component apis, reading a particular field in register would involve first read the register and then perform shift operations. Ex: to read from a field mask of 0xf0 val = snd_soc_component_read(component, reg); field = ((val & 0xf0) >> 0x4); This is sometimes prone to errors and code become less readable! With this new api we could just do field = snd_soc_component_read_field(component, reg, 0xf0); this makes it bit simple, easy to write and less error prone! This also applies to writing! There are various places in kernel which provides such field interfaces however soc_component seems to be missing this.

This kind of duplicated code can be a hotbed of bugs, thus, we want to share soc_pcm_close() and rollback. Now, soc_pcm_open/close() are handling 1) snd_soc_dai_startup/shutdown() 2) snd_soc_link_startup/shutdown() => 3) snd_soc_component_module_get/put() => 4) snd_soc_component_open/close() 5) pm_runtime_put/get() This patch is for 3) snd_soc_component_module_get/put() 4) snd_soc_component_open/close(). The idea of having bit-flag or counter is not enough for this purpose. For example if one DAI is used for 2xPlaybacks for some reasons, and if 1st Playback was succeeded but 2nd Playback was failed, 2nd Playback rollback doesn't need to call shutdown. But it has succeeded bit-flag or counter via 1st Playback, thus, 2nd Playback rollback will call unneeded shutdown. And 1st Playback's necessary shutdown will not be called, because bit-flag or counter was cleared by wrong 2nd Playback rollback. To avoid such case, this patch marks substream pointer when open() was succeeded. If rollback needed, it will check rollback flag and marked substream pointer. One note here is that it cares *current* open() only now. but we might want to check *whole* marked substream in the future.

SOF is setting module_get_upon_open to 1 for component drivers which works correctly for audio stream but when compressed stream is used then the module is not protected.

The idea of having bit-flag or counter is not enough for this purpose. For example if one DAI is used for 2xPlaybacks for some reasons, and if 1st Playback was succeeded but 2nd Playback was failed, 2nd Playback rollback doesn't need to call shutdown. But it has succeeded bit-flag or counter via 1st Playback, thus, 2nd Playback rollback will call unneeded shutdown. And 1st Playback's necessary shutdown will not be called, because bit-flag or counter was cleared by wrong 2nd Playback rollback. To avoid such case, this patch marks substream pointer when hw_params() was succeeded. If rollback needed, it will check rollback flag and marked substream pointer. One note here is that it cares *previous* hw_params() only now, but we might want to check *whole* marked substream in the future.

ASoC: soc-component: add mark for snd_soc_pcm_component_hw_params/free() soc_pcm_hw_params() does rollback when failed (A), but, it is almost same as soc_pcm_hw_free(). static int soc_pcm_hw_params(xxx) { ... if (ret < 0) goto xxx_err; ... return ret; ^ component_err: | ... | interface_err: (A) ... | codec_err: | ... v return ret; } The difference is soc_pcm_hw_free() is for all dai/component/substream, rollback is for succeeded part only. This kind of duplicated code can be a hotbed of bugs, thus, we want to share soc_pcm_hw_free() and rollback. Now, soc_pcm_hw_params/free() are handling 1) snd_soc_link_hw_params/free() => 2) snd_soc_pcm_component_hw_params/free() 3) snd_soc_dai_hw_params/free() This patch is for 2) snd_soc_pcm_component_hw_params/free(). The idea of having bit-flag or counter is not enough for this purpose. For example if one DAI is used for 2xPlaybacks for some reasons, and if 1st Playback was succeeded but 2nd Playback was failed, 2nd Playback rollback doesn't need to call shutdown. But it has succeeded bit-flag or counter via 1st Playback, thus, 2nd Playback rollback will call unneeded shutdown. And 1st Playback's necessary shutdown will not be called, because bit-flag or counter was cleared by wrong 2nd Playback rollback. To avoid such case, this patch marks substream pointer when hw_params() was succeeded. If rollback needed, it will check rollback flag and marked substream pointer. One note here is that it cares *previous* hw_params() only now, but we might want to check *whole* marked substream in the future. This patch is using macro named "push/pop", so that it can be easily update.

ASoC: soc-component: add snd_soc_pcm_component_trigger() We have 2 type of component functions snd_soc_component_xxx() is focusing to component itself, snd_soc_pcm_component_xxx() is focusing to rtd related component. Now we can update snd_soc_component_trigger() to snd_soc_pcm_component_trigger(). This patch do it.

This patch adds trigger mark for DAI/Component/Link, and do STOP if START/RESUME/PAUSE_RELEASE were failed. Because it need to use new rollback parameter, we need to modify DAI/Component/Link trigger functions in the same time.

ASoC: soc-component: Add snd_soc_pcm_component_ack Add snd_soc_pcm_component_ack back, which can be used to get an updated buffer pointer in the platform driver. On Asymmetric multiprocessor, this pointer can be sent to Cortex-M core for audio processing.

ASoC: soc-component: add snd_soc_pcm_component_delay() Current soc-pcm.c :: soc_pcm_pointer() is assuming that component driver might update runtime->delay silently in snd_soc_pcm_component_pointer() (= A). static snd_pcm_uframes_t soc_pcm_pointer(...) { ... /* clearing the previous total delay */ => runtime->delay = 0; (A) offset = snd_soc_pcm_component_pointer(substream); /* base delay if assigned in pointer callback */ => delay = runtime->delay; ... } 1) The behavior that ".pointer callback secretly updates runtime->delay" is strange and confusable. 2) Current snd_soc_pcm_component_pointer() uses 1st found component's .pointer callback only, thus it is no problem for now. But runtime->delay might be overwrote if it adjusted to multiple components in the future. 3) Component delay is updated at .pointer callback timing (secretly). But some components which doesn't have .pointer callback might want to increase runtime->delay for some reasons. We already have .delay function for DAI, but not have for Component. This patch adds new snd_soc_pcm_component_delay() for it.

ASoC: soc-component: add snd_soc_pcm_component_pointer() Current ALSA SoC is directly using component->driver->ops->xxx, thus, the code nested deeply, and it makes code difficult to read, and is not good for encapsulation. We want to implement component related function at soc-component.c, but, some of them need to care whole snd_soc_pcm_runtime (= rtd) connected component. Let's call component related function which need to care with for_each_rtdcom() loop as snd_soc_pcm_component_xxx(). This patch adds new snd_soc_pcm_component_pointer() and use it.
