(E)AC3, DTS, MPEG-H support in tinycompress and the kernel uapi?
by GitHub issues - opened 22 Nov '22

22 Nov '22

alsa-project/tinycompress issue #20 was opened from dv1: Have there been discussions about adding support for (E)AC3, DTS, and MPEG-H? These days, 3D Audio is a use case where the Compress-Offload API is useful. It therefore would make sense to add support for these formats. I'm talking about direct support, not through IEC958 / IEC61937 payloading. I know that some HW vendors add their own custom changes to tinycompress to support these formats, so why not add these to upstream?

[PATCH 1/9] sound: sdw: Add hw_params to SoundWire config helper function
by Charles Keepax 22 Nov '22

22 Nov '22

The vast majority of the current users of the SoundWire framework have almost identical code for converting from hw_params to SoundWire configuration. Whilst complex devices might require more, it is very likely that most new devices will follow the same pattern. Save a little code by factoring this out into a helper function. Signed-off-by: Charles Keepax <ckeepax(a)opensource.cirrus.com> --- I was a little bit two minds about whether to make this an inline or not, so any thoughts on that would be super welcome. The function does very little, especially given that SNDRV_PCM_STREAM_PLAYBACK == SDW_DATA_DIR_RX so the if is also really just an assignment.

[PATCH 0/4] Minor SoundWire clean ups
by Charles Keepax 21 Nov '22

21 Nov '22

Just some minor tidy ups and preparation for starting to upstream some Cirrus SoundWire devices. The first three patches are pretty trivial, the last patch which moves the remaining core over to using the no_pm functions could probably use some careful review. Thanks, Charles Charles Keepax (3): soundwire: Provide build stubs for common functions soundwire: debugfs: Switch to sdw_read_no_pm soundwire: stream: Move remaining register accesses over to no_pm Simon Trimmer (1): soundwire: bus: export sdw_nwrite_no_pm and sdw_nread_no_pm functions drivers/soundwire/bus.c | 10 ++-- drivers/soundwire/debugfs.c | 11 +++- drivers/soundwire/stream.c | 30 +++++------ include/linux/soundwire/sdw.h | 94 +++++++++++++++++++++++++++++++---- 4 files changed, 114 insertions(+), 31 deletions(-) -- 2.30.2

[PATCH -next] ALSA: seq: fix undefined behavior in bit shift for SNDRV_SEQ_FILTER_USE_EVENT
by Baisong Zhong 21 Nov '22

21 Nov '22

Shifting signed 32-bit value by 31 bits is undefined, so changing significant bit to unsigned. The UBSAN warning calltrace like below: UBSAN: shift-out-of-bounds in sound/core/seq/seq_clientmgr.c:509:22 left shift of 1 by 31 places cannot be represented in type 'int' ...
