2015-03-04T11:12:59+00:00

ALSA: compress: Embed struct device

2015-02-02T13:42:45+00:00

Like previous patches, this one embeds the struct device into struct
snd_compr.  As the dev field wasn't used beforehand, it's reused as
the new device struct.

ALSA: compress_driver.h: include sound/core.h explicitly

2015-01-13T15:50:31+00:00

Fixes the following compilation error:

   include/sound/compress_driver.h: In function ‘snd_compr_drain_notify’:
   include/sound/compress_driver.h:177:2: error: implicit declaration of function ‘snd_BUG_ON’ [-Werror=implicit-function-declaration]
     if (snd_BUG_ON(!stream))

snd_BUG_ON() is defined in sound/core.h but the file is not included explicitly,
so include it.

ALSA: compress: fix drain calls blocking other compress functions (v6)

2013-11-07T09:12:27+00:00

The drain and drain_notify callback were blocked by low level driver
until the draining was complete. Due to this being invoked with big
fat mutex held, others ops like reading timestamp, calling pause, drop
were blocked.

So to fix this we add a new snd_compr_drain_notify() API. This would
be required to be invoked by low level driver when drain or partial
drain has been completed by the DSP. Thus we make the drain and
partial_drain callback as non blocking and driver returns immediately
after notifying DSP.  The waiting is done while releasing the lock so
that other ops can go ahead.

[ The commit 917f4b5cba78 was wrongly applied from the preliminary
  patch.  This commit corrects to the final version.
  Sorry for inconvenience!  -- tiwai ]

ALSA: compress_core: Rework writes to use cumulative values

This patch reworks the writes to use cumulative values thus making the
app_pointer unecessary and removing it.

Only tested as far as build.

ALSA: compress_core: Deconstify copy callback buffer

2013-04-21T07:53:00+00:00

The buffer passed to the copy callback should not be const because the
copy callback can be used for capture and playback.
