Unfortunately, the master_slave buffer pointers are not always in sync with
the presented avail value and the higher layers (like write_areas) got
confused. Create own hw_ptr and appl_ptr.
This commit also tries to fix the hwsync and delay implementation (iterate
through all slaves).
The multi plugin was designed only for hardware which runs really in sync.
Anyway, users are trying to use this plugin for other purposes.

Some applications do not expect that get_period_size_min() could

Due to there is no use case for having a period size of 0 this patch
disallows a period size of 0 when using the null plugin.

We used to put the additional include path $includedir/alsa in
pkgconfig just because some applications have included asoundlib.h
like
#include <asoundlib.h>
although the canonical form should be
#include <alsa/asoundlib.h>
However, adding this include path is significantly dangerous due to
possible conflicts of file names like version.h. It's already the
reason to discourage people using alsa.pc for the packages.
In this patch, the additional include path from alsa.pc is dropped
finally. At the same time, as a rescue plan for the programs
including via <asoundlib.h>, a stub header file is provided in
include/sound/asoundlib.h. It just includes alsa/asoundlib.h with a
warning to suggest for replacing with alsa/asoundlib.h.
Actually this is the same file as we install into sys/asoundlib.h, so
the whole changes are very minimal here.

In snd_pcm_dshare_sync_area() when 'slave_hw_ptr' rolls over
'slave_boundary', the wrong variable is checked ('dshare->slave_hw_ptr' vs
the local 'slave_hw_ptr'). In some cases, this results in 'slave_hw_ptr'
not rolling over correctly. 'slave_size' and 'size' are then much too
large, and the for loop blocks for several minutes copying samples.
This was likely only triggered on 32-bit systems, since the PCM boundary
is computed based on LONG_MAX and is much larger on 64-bit systems.
This same change was made to pcm_dmix in commit
6c7f60f7a9 ("Fix boundary overlap”) from
June 2005.

Commit f91cc3c7d6 ("Update chtrt5645 ucm variants to use
bytcr/PlatformEnableSeq.conf component") updated the
following 2 comments:
# codec0_out settings (used if SSP2 is connected to aif1)
# modem_out settings (used if SSP0 is connected to aif2)
Specifically it added the " to aif1" resp. " to aif2" part of the comments.
This is not correct, AIF1 / AIF2 are something which is present on
Realtek codecs only, and either one can be used indepedent of
SSP0 or SSP2 being used (the comments in the chtrt5645 UCM profile
before this change were wrong / outdated).
Besides there not being any relationship between SSP0 or SSP2 being
used, bytcr/PlatformEnableSeq.conf is also used with other codecs,
e.g. the ESS8316 codec where this is not applicable at all.
Therefor this commit removes the " to aif?" part of the comments again
to avoid confusing people reading this in the future.

snd_pcm_hw_sw_params() in pcm_hw.c tries to abuse the reserved bits
for passing period_Event flag. In this hackish way, we clear the
reserved bits at beginning, and restore before returning. However,
the code paths that return earlier don't restore the value, hence when
user calls this function twice, it may pass an unexpected value.
This patch fixes the failure, restoring the value always before
returning from the function.

During my recent work on the bytcht-es8316 UCM profile I realized that the
bytcr-rt5651 devices with a single speaker use a differential setup just
like the es8316 does. The tell-tale here is the speaker going quiet when
playing the exact same sound on both channels when things are configured
for stereo speakers.
I've run some tests and the rt5651 does have a special mono balanced out
mode for its line-out but using this results in the same sound (and the
same loudness / volume of the sound) as our current solution, so adding
support for this to the kernel buys us nothing.
This commit makes no changes, it just documents my findings in a big
comment for future reference.

The recent change to support the drain via polling caused a regression
for pulse plugin; with speaker-test -c2 -twav with pulse, it leads to
either no sounds or stall.
The only sensible behavior change in the commit wrt pulse plugin is
that now it starts the stream before calling drain callback. This
supposed to be correct, but it seems hitting a pulse plugin bug.
The start before drain callback is only a matter of consistency, and
since this doesn't work for the single existing plugin using drain
callback, we don't need to stick with this behavior.
For addressing the regression, we check the presence of the drain
callback and start the stream only when it doesn't exist, i.e. only in
drain-via-poll mode.

Without this patch it is not possible to link the channel and format
parameter if snd_pcm_extplug_set_param_*() or
snd_pcm_extplug_set_slave_param_*() is called. Therefore the client and
slave parameter can differ. So the extplug has to implement conversion.
To avoid this the new snd_pcm_extplug_set_param_link() function can be
called.
As a reproduction sceanrio the following extplug source code can be used:
===
static snd_pcm_sframes_t my_transfer(snd_pcm_extplug_t *e,
const snd_pcm_channel_area_t *da, snd_pcm_uframes_t dof,
const snd_pcm_channel_area_t *sa, snd_pcm_uframes_t sof,
snd_pcm_uframes_t s) {
return s;
}
static const snd_pcm_extplug_callback_t my_own_callback = {
.transfer = my_transfer
};
SND_PCM_PLUGIN_DEFINE_FUNC(my_plug) {
snd_config_iterator_t i, next;
snd_config_t *slave = NULL;
snd_pcm_extplug_t *myplug;
snd_config_for_each(i, next, conf) {
snd_config_t *n = snd_config_iterator_entry(i);
const char *id;
if (snd_config_get_id(n, &id) < 0)
continue;
if (strcmp(id, "comment") == 0 || strcmp(id, "type") == 0)
continue;
if (strcmp(id, "slave") == 0) {
slave = n;
continue;
}
return -EINVAL;
}
myplug = calloc(1, sizeof(*myplug));
myplug->version = SND_PCM_EXTPLUG_VERSION;
myplug->callback = &my_own_callback;
snd_pcm_extplug_create(myplug, name, root, slave, stream, mode);
snd_pcm_extplug_set_param_minmax(myplug,
SND_PCM_EXTPLUG_HW_CHANNELS, 1, 16);
// snd_pcm_extplug_set_param_link(myplug, SND_PCM_EXTPLUG_HW_CHANNELS, 1);
*pcmp = myplug->pcm;

To use this plugin the following ALSA configuration is required:
pcm.myplug {
type my_plug
slave.pcm hw:Dummy
}
With this configuration without this patch
snd_pcm_hw_params_get_channels_max() will always return 16 channels
independent of the supported channels of the dummy device. Due to that for
example the start up of JACK would fail:
$ modprobe snd_dummy
$ jackd -d alsa -P myplug
ALSA: cannot set channel count to 16 for playback
ALSA: cannot configure playback channel

Many UCM profiles include the UCM profile components under ucm/*
subdirectories and thusly put <searchdir:ucm> at each place. This is
rather cumbersome.
This patch makes the UCM parser to set the default include path, so
that each profile no longer needs to set searchdir. All the
<searchdir:ucm> lines currently found in the profiles are removed
gracefully, too.
For the needed implementation, a new helper,
_snd_config_load_with_include() is introduced. It's not exported,
only for the use inside alsa-lib.

We have placed UCM profile snippets to be included by the main config
files also in the same directory, src/conf/ucm, it confuses alsaucm
program that scans over all subdirectories. It thinks such a file is
also the main config file, and spews errors like:
% alsaucm
ALSA lib utils.c:67:(uc_mgr_config_load) could not open configuration file /usr/share/alsa/ucm/bytcr/bytcr.conf
ALSA lib parser.c:1427:(load_master_config) error: could not parse configuration for card bytcr
alsaucm: unable to obtain card list: No such file or directory
Actually we already defined the subdirectory for such components, and
they are skipped at parsing the main configs. So we just need to move
the files there -- this is what's done here.
One more thing done here is to add a new component subdirectory,
platforms, for definitions bytcr/* that don't match with neither the
existing ones (codecs nor dsps).

These changes are required due to the kernel
commit 07b7acb51d283d8469696c906b91f1882696a4d4
("ASoC: rsnd: update pointer more accurate")
Issue is that snd_pcm_wait() goes back to waiting because the hw_ptr
is not period aligned. Therefore snd_pcm_wait() will block for a longer
time as required.
With these rcar driver changes the exact position of the dma is returned.
During snd_pcm_start they read hw_ptr as reference, and this hw_ptr
is now not period aligned, and is a little ahead over the period while it
is read. Therefore when the avail is calculated during snd_pcm_wait(),
it is missing the avail_min by a few frames.
An additional option hw_ptr_alignment is provided to dmix configuration,
to allow the user to configure the slave application and hw pointer
alignment at startup
