Both USB audio cards on Lenovo ThinkStation P620 don't support IEC958,
so disable IEC958 accordingly.

pcm: iec958: set channel status bits according to rate and format

This mimics snd_pcm_create_iec958_consumer in the kernel.

The rate and wordlength bits will only be modified if they are
set to "not indicated", which is now the default if no status
option is used.

This allows applications to override parameters determined from
the stream or implement channel status bits extensions without
needing to change pcm_iec958 code.

4 years agopcm: iec958: implement HDMI HBR audio formatting
Matthias Reichl [Mon, 13 Jul 2020 21:17:03 +0000 (23:17 +0200)]
pcm: iec958: implement HDMI HBR audio formatting

High bitrate compressed audio data like DTS HD or MAT is usually
packed into 8-channel data. The HDMI specs state this has to be
formatted as a single IEC958 stream, compared to normal multi-
channel PCM data which has to be formatted as parallel IEC958 streams.

As this single-stream formatting mode may break existing setups that
expect non-PCM multichannel data to be formatted as parallel IEC958
streams it needs to be explicitly selected by setting the hdmi_mode
option to true.

The single-stream formatting implementation is prepared to cope with
arbitrary channel counts but only limited testing was done for channel
counts other than 8.

4 years agopcm: dmix: Fix semaphore usage with lockless operation

pcm: dmix: Fix semaphore usage with lockless operation

As Maarten Baert recently reported, the current dmix code applies the
semaphore unnecessarily around mixing streams even when the lockless
mix operation is used on x86.  This was rather introduced mistakenly
at the commit 267d7c728196 ("Add support of little-endian on
i386/x86_64 dmix") where the generic dmix code was included on x86,
too.

For achieving the original performance back, this patch changes the
semaphore handling to be checked at run time instead of statically at
compile time.
