[alsa-devel] [PATCH] [sound] hdac-codec runtime suspended at PM:Suspend.
by Anshuman Gupta 28 Aug '18

28 Aug '18

Keep hdac-codec to be in runtime suspended while entering to suspend. If hdac-codec is already in runtime suspend state skip its power down sequence in prepare, power up sequence in complete phase. Avoid resuming hdac controller PCI device 00:1f.3 from runtime suspend state in case hdac-codec already in runtime-suspend state, this is unnecessary and block the direct complete even for hdac controller PCI device 00:1f.3. This enabled direct complete path for hdac-codec and PCI device 00:1f.3.

[alsa-devel] [PATCH v2 0/6] ASoC: SOF driver dependencies
by Liam Girdwood 18 Jun '18

18 Jun '18

This series is a set of ASoC core and topology updates needed by the SOF driver. The SOF driver uses topology extensively to define most of the characteristsics of an audio card with the exception of some immutable items like hardware backend DAI links. The SOF driver also allows for reuse of existing upstream machine drivers by re-writting some aspects of the DAI link and DAPM configuration with data from topology. i.e. existing machine drivers can be reused with different topologies. V2: Rebased on top of today for-next, V1 was probably missing 1/6 meaning the others would not apply. Liam Girdwood (6): ASoC: core: Allow topology to override machine driver FE DAI link config. ASoC: core: Add name prefix for machines with topology rewrites ASoC: topology: Give more data to clients via callbacks ASoC: topology: Add callback for DAPM route load/unload ASoC: topology: Check widget kcontrols before deref.

21 May '18

From: Srinivas Kandagatla <srinivas.kandagatla(a)linaro.org> This patchset aims to provide a basic version of QCOM DSP based audio support which is available in downstream andriod kernels. This patchset support audio playback on HDMI-RX, MI2S, SLIMBus and will add support to other features as we move on. QDSP has both static and dynamic modules. static modules like AFE (Audio FrontEnd), ADM (Audio Device Manager), ASM(Audio Stream Manager) and CORE to provide this audio services. All these services use APR (Asynchronous Packet Router) protocol via smd/glink transport to communicate with Application processor. More details on each module is availble in there respective patch. This patchset is tested on DB820c, with HDMI audio playback, MI2S on DB410c on top of mainline, Also tested SLIMBus analog audio using wcd9355 with an additional patches.

[alsa-devel] [PATCH v6 00/24] ASoC: qcom: Add support to QDSP based Audio
by srinivas.kandagatla＠linaro.org 21 May '18

21 May '18

From: Srinivas Kandagatla <srinivas.kandagatla(a)linaro.org> Thankyou everyone for providing feedback and testing v5 patchset. This patchset aims to provide a basic version of QCOM DSP based audio support which is available in downstream andriod kernels. This patchset support audio playback on HDMI-RX, MI2S, SLIMBus and will add support to other features as we move on. QDSP has both static and dynamic modules. static modules like AFE (Audio FrontEnd), ADM (Audio Device Manager), ASM(Audio Stream Manager) and CORE to provide this audio services. All these services use APR (Asynchronous Packet Router) protocol via smd/glink transport to communicate with Application processor. More details on each module is availble in there respective patch. This patchset is tested on DB820c, with HDMI audio playback, MI2S on DB410c on top of mainline, Also tested SLIMBus analog audio using wcd9355 with an additional patches. Patches are also tested on SDM845 by Rohit.
