ASoC: soc-component: add mark for snd_soc_pcm_component_pm_runtime_get/put()
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 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.

ASoC: soc-compress: Reposition and add pcm_mutex
If panic_on_warn is set and compress stream(DPCM) is started,
then kernel panic occurred because card->pcm_mutex isn't held appropriately.
In the following functions, warning were issued at this line
"snd_soc_dpcm_mutex_assert_held".
static int dpcm_be_connect(struct snd_soc_pcm_runtime *fe,
struct snd_soc_pcm_runtime *be, int stream)

}
int dpcm_dapm_stream_event(struct snd_soc_pcm_runtime *fe, int dir,
int event)

}
These functions are called by soc_compr_set_params_fe, soc_compr_open_fe
and soc_compr_free_fe
without pcm_mutex locking. And this is call stack.

ASoC: soc-compress: Reposition and add pcm_mutex
If panic_on_warn is set and compress stream(DPCM) is started,
then kernel panic occurred because card->pcm_mutex isn't held appropriately.
In the following functions, warning were issued at this line
"snd_soc_dpcm_mutex_assert_held".
static int dpcm_be_connect(struct snd_soc_pcm_runtime *fe,
struct snd_soc_pcm_runtime *be, int stream)
{
...
snd_soc_dpcm_mutex_assert_held(fe);
...
}
void dpcm_be_disconnect(struct snd_soc_pcm_runtime *fe, int stream)
{
...
snd_soc_dpcm_mutex_assert_held(fe);
...
}
void snd_soc_runtime_action(struct snd_soc_pcm_runtime *rtd,
int stream, int action)
{
...
snd_soc_dpcm_mutex_assert_held(rtd);
...
}
int dpcm_dapm_stream_event(struct snd_soc_pcm_runtime *fe, int dir,
int event)
{
...
snd_soc_dpcm_mutex_assert_held(fe);
...
}
These functions are called by soc_compr_set_params_fe, soc_compr_open_fe
and soc_compr_free_fe
without pcm_mutex locking. And this is call stack.

ASoC: soc-core: remove snd_soc_rtdcom_list
Current ALSA SoC is using struct snd_soc_rtdcom_list to
connecting component to rtd by using list_head.
struct snd_soc_rtdcom_list {
struct snd_soc_component *component;
struct list_head list; /* rtd::component_list */
};
struct snd_soc_pcm_runtime {
...
struct list_head component_list; /* list of connected components */
...
};
The CPU/Codec/Platform component which will be connected to rtd (a)
is indicated via dai_link at snd_soc_add_pcm_runtime()
int snd_soc_add_pcm_runtime(...)
{
...
/* Find CPU from registered CPUs */
rtd->cpu_dai = snd_soc_find_dai(dai_link->cpus);
...
(a) snd_soc_rtdcom_add(rtd, rtd->cpu_dai->component);
...
/* Find CODEC from registered CODECs */
(b) for_each_link_codecs(dai_link, i, codec) {
rtd->codec_dais[i] = snd_soc_find_dai(codec);
...
(a) snd_soc_rtdcom_add(rtd, rtd->codec_dais[i]->component);
}
...
/* Find PLATFORM from registered PLATFORMs */
(b) for_each_link_platforms(dai_link, i, platform) {
for_each_component(component) {
...
(a) snd_soc_rtdcom_add(rtd, component);
}
}
}
It shows, it is possible to know how many components will be
connected to rtd by using
dai_link->num_cpus
dai_link->num_codecs
dai_link->num_platforms
If so, we can use component pointer array instead of list_head,
in such case, code can be more simple.
This patch removes struct snd_soc_rtdcom_list that is only
of temporary value, and convert to pointer array.

ASoC: soc-compress: add snd_compress_ops
Current snd_soc_component_driver has compr_ops, and each driver can
have callback via it. But, it is mainly created for ALSA, thus, it
doesn't have "component" as parameter.
Thus, each callback can't know it is called for which component.
Each callback currently is getting "component" by using
snd_soc_rtdcom_lookup() with driver name.
--- ALSA SoC ---
...
if (component->driver->compr_ops &&
component->driver->compr_ops->open)
=> return component->driver->compr_ops->open(stream);
...
--- driver ---
static int xxx_open(struct snd_compr_stream *stream)
{
struct snd_soc_pcm_runtime *rtd = stream->private_data;
=> struct snd_soc_component *component = snd_soc_rtdcom_lookup(..);
...
}
It works today, but, will not work in the future if we support multi
CPU/Codec/Platform, because 1 rtd might have multiple same driver
name component.
To solve this issue, each callback need to be called with component.
We already have many component driver callbacks.
This patch adds new snd_compress_ops, and call it with "component".
