[alsa-devel] Cards that support ADPCM in hardware
by Alexander E. Patrakov 16 Oct '14

16 Oct '14

Hello. Due to the "remove support for old hardware" topic that is going to be discussed at the Linux Plumbers Conference, let me see if there is actually any supported hardware that supports ADPCM. A quick grep for ADPCM in the sound directory yields this: ./isa/wss/wss_lib.c: ISA, Windows sound system ./isa/sb/sb16_{main,csp}.c: ISA, classic SB16 card ./oss/ad1848.c: Another ISA card, OSS-only ./sh/aica.c: for SEGA Dreamcast console ./sparc/cs4231.c: I don't know about this Is any of the hardware listed above still used (or usable) with the current kernels? -- Alexander E. Patrakov

[alsa-devel] [PATCH v2 01/53] dmaengine: Make the destination abbreviation coherent
by Maxime Ripard 16 Oct '14

16 Oct '14

The dmaengine header abbreviates destination as at least two different strings. Make a coherent use of a single one.

[alsa-devel] [PATCH v10 0/5] Add mrfld DSP topology and widgets
by Vinod Koul 16 Oct '14

16 Oct '14

This patch series adds DPCM and DAPM widgets to handle DSP topology in the SST platform driver for merrifield. changes in v10: - add SST_GAIN_NUM_CONTROLS for use in gain cell size calculation changes in v9: - fix some corner conditions and error checks changes in v8: - fix the locking and comments blobs - fix the send_ssp_slot to send IPC on none - fix controls to have "Volume" and "Switch" wherever neccessary - add mute for CPU dai in asoc core patch Vinod Koul (5): ASoC: Intel: mrfld: add the gain controls ASoC: Intel: mrfld: add DSP core controls ASoC: Intel: mrfld: add the DSP DAPM widgets ASoC: Intel: mfld-pcm: add FE and BE ops ASoC: Intel: mrfld: add the DSP mixers sound/soc/intel/Kconfig | 2 +- sound/soc/intel/sst-atom-controls.c | 1208 ++++++++++++++++++++++++++++++- sound/soc/intel/sst-atom-controls.h | 428 +++++++++++ sound/soc/intel/sst-mfld-platform-pcm.c | 153 ++++- sound/soc/intel/sst-mfld-platform.h | 4 + 5 files changed, 1764 insertions(+), 31 deletions(-)
