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".

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 {

It shows, it is possible to know how many components will be

If so, we can use component pointer array instead of list_head,

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".
--- ALSA SoC ---
...
if (component->driver->compress_ops->open)
=> return component->driver->compress_ops->open(
component, substream);

struct snd_compr_stream *stream)

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);
...

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".

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-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);
...

/* Find CODEC from registered CODECs */

(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.

}
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".

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.

{
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".
