In commit 32c9c06adb ("ASoC: mediatek: disable buffer pre-allocation")
buffer pre-allocation was disabled to accommodate newer platforms that
have a limited reserved memory region for the audio frontend.
Turns out disabling pre-allocation across the board impacts platforms
that don't have this reserved memory region. Buffer allocation failures
have been observed on MT8173 and MT8183 based Chromebooks under low
memory conditions, which results in no audio playback for the user.
Since some MediaTek platforms already have dedicated reserved memory
pools for the audio frontend, the plan is to enable this for all of
them. This requires device tree changes. As a fallback, reinstate the
original policy of pre-allocating audio buffers at probe time of the
reserved memory pool cannot be found or used.
This patch covers the MT8173, MT8183, MT8186 and MT8192 platforms for
now, the reason being that existing MediaTek platform drivers that
supported reserved memory were all platforms that mainly supported
ChromeOS, and is also the set of devices that I can verify.

Change the function to dynamically allocate it instead.
There is probably a better way to do it since only two integer fields
inside of that structure are actually used, but this is the simplest
rework for the moment.

This patch modifies the assignment of machine structure pointers in the

Additionally, the declarations of the machine arrays in amd.h have been

further cleaned up by declaring the codec structures in
amd-acpi-mach.c as static, reflecting their intended usage.

All four Qualcomm SoC macro codecs define DAI IDs in an enum starting
with AIF_INVALID=0, which is nowhere used in the code thus actual DAI
IDs start from 1. Drivers do not have their own of_xlate_dai_name(),
thus snd_soc_get_dlc() expects the DTS to start numbering DAIs from 0,
which creates confusing debugging scenario, e.g. DTS should use
<&lpass_wsamacro 2> for WSA_MACRO_AIF_VI with dai->id=3.
This also wastes some space, because drivers allocate few arrays for all
DAIs and basically the [0] is never used.
Drop the confusing first AIF_INVALID DAI identifier so the enum with DAI
IDs will start from 0. This has little functional impact and does not
affect the ABI, except saving a few bytes of memory per driver.

Qcom lpass is using component->id to keep DAI ID (A).
(S) static int lpass_platform_pcmops_open(
sruct snd_soc_component *component,
struct snd_pcm_substream *substream)
{ ^^^^^^^^^(B0)
...
(B1) struct snd_soc_pcm_runtime *soc_runtime = snd_soc_substream_to_rtd(substream);
(B2) struct snd_soc_dai *cpu_dai = snd_soc_rtd_to_cpu(soc_runtime, 0);
...
(B3) unsigned int dai_id = cpu_dai->driver->id;
(A) component->id = dai_id;
...
}
This driver can get dai_id from substream (B0 - B3).
In this driver, below functions get dai_id from component->id (A).
(X) lpass_platform_pcmops_suspend()
(Y) lpass_platform_pcmops_resume()
(Z) lpass_platform_copy()
Here, (Z) can get it from substream (B0 - B3), don't need to use
component->id (A). On suspend/resume (X)(Y), dai_id can only be obtained
from component->id (A), because there is no substream (B0) in function
parameter.
But, component->id (A) itself should not be used for such purpose.
It is intilialized at snd_soc_component_initialize(), and parsed its ID
(= component->id) from device name (a).
int snd_soc_component_initialize(...)
{
...
if (!component->name) {
(a) component->name = fmt_single_name(dev, &component->id);
... ^^^^^^^^^^^^^
}
...
}
Unfortunately, current code is broken to start with.
There are many regmaps that the driver cares about, however its only
managing one (either dp or i2s) in component suspend/resume path.
I2S regmap is mandatory however other regmaps are setup based on flags
like "hdmi_port_enable" and "codec_dma_enable".
Correct thing for suspend/resume path to handle is by checking these
flags, instead of using component->id.
