      selftests: alsa - add PCM test · aba51cd0
      Jaroslav Kysela authored 
      This initial code does a simple sample transfer tests. By default,
all PCM devices are detected and tested with short and long
buffering parameters for 4 seconds. If the sample transfer timing
is not in a +-100ms boundary, the test fails. Only the interleaved
buffering scheme is supported in this version.

The configuration may be modified with the configuration files.
A specific hardware configuration is detected and activated
using the sysfs regex matching. This allows to use the DMI string
(/sys/class/dmi/id/* tree) or any other system parameters
exposed in sysfs for the matching for the CI automation.

The configuration file may also specify the PCM device list to detect
the missing PCM devices.

v1..v2:
  - added missing alsa-local.h header file

      ALSA: pcm: avoid nused-but-set-variable warning · 3827597a
      Kuninori Morimoto authored 
      It will indicate below warning if W=1 was added and CONFIG_SND_DEBUG
was not set. This patch adds __maybe_unused and avoid it.

      ALSA: memalloc: Allocate more contiguous pages for fallback case · cc265163
      Takashi Iwai authored 
      Currently the fallback SG allocation tries to allocate each single
page, and this tends to result in the reverse order of memory
addresses when large space is available at boot, as the kernel takes a
free page from the top to the bottom in the zone.  The end result
looks as if non-contiguous (although it actually is).  What's worse is
that it leads to an overflow of BDL entries for HD-audio.

For avoiding such a problem, this patch modifies the allocation code
slightly; now it tries to allocate the larger contiguous chunks as
much as possible, then reduces to the smaller chunks only if the
allocation failed -- a similar strategy as the existing
snd_dma_alloc_pages_fallback() function.

Along with the trick, drop the unused address array from
snd_dma_sg_fallback object.  It was needed in the past when
dma_alloc_coherent() was used, but with the standard page allocator,
it became superfluous and never referred.

Fixes: a8d302a0 ("ALSA: memalloc: Revive x86-specific WC page allocations again")
