[PATCH v2 0/7][RESEND] ASoC: merge soc_pcm_open() rollback and soc_pcm_close()
Hi Mark
1 month past and nothing happened. This is resend of v2 patch-set.
soc_pcm_open() does rollback when failed (A), but, it is almost same as soc_pcm_close().
static int soc_pcm_open(xxx) { ... if (ret < 0) goto xxx_err; ... return 0;
^ config_err: | ... | rtd_startup_err: (A) ... | component_err: | ... v return ret; }
This kind of duplicated code can be a hotbed of bugs, thus, this patch-set share soc_pcm_close() and rollback.
v1 -> v2 - indicate more detail background/logic on git-log

soc_pcm_open() does rollback when failed (A), but, it is almost same as soc_pcm_close().
static int soc_pcm_open(xxx) { ... if (ret < 0) goto xxx_err; ... return 0;
^ config_err: | ... | rtd_startup_err: (A) ... | component_err: | ... v return ret; }
The difference is soc_pcm_close() 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_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 1) snd_soc_dai_startup/shutdown().
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 startup() was succeeded. If rollback needed, it will check rollback flag and marked substream pointer.
One note here is that it cares *current* startup() 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.

The difference is soc_pcm_close() 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_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 5) pm_runtime_put/get().
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 get() was succeeded. If rollback needed, it will check rollback flag and marked substream pointer.
One note here is that it cares *current* get() 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.

soc_pcm_open() does rollback when failed (A), but, it is almost same as soc_pcm_close().
static int soc_pcm_open(xxx) { ... if (ret < 0) goto xxx_err; ... return 0;

The difference is soc_pcm_close() 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_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()
Now, 1) to 5) are handled. This patch adds new soc_pcm_clean() and call it from soc_pcm_open() as rollback, and from soc_pcm_close() as normal close handler.
One note here is that it don't need to call snd_soc_runtime_deactivate() when rollback case, because it will be called without snd_soc_runtime_activate(). It also don't need to call snd_soc_dapm_stream_stop() when rollback case.

This patch landed in linux next-20200929 as commit 140a4532cdb8 ("ASoC: soc-pcm: add soc_pcm_clean() and call it from soc_pcm_open/close()"). Sadly it causes a regression in ALSA operation on my various test boards: Exynos4412 based Trats2, Exynos5410 based Odroid XU, Exynos5250 Snow Chromebook and other. The first app, which tries to open ALSA device fails. Then, on the second try, it work.
Here is a log from Odroid XU:

All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying to this mail.
Thanks, Mark

All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying to this mail.
Thanks, Mark
