sound: X86: Xilinx : PCIe : ALSA PCM sample driver code
by Muni Sekhar 25 Nov '21

25 Nov '21

Hi All, I am using a Linux X86 machine where Xilinx FPGA sound card connected to X86 machine's PCIe slot. The sound card supports PCM playback and capture capabilities. I need to write an ALSA driver for my sound card. Since I am using X86 machine and it don't have the devicetree, can someone please suggest the what driver architecture I should use for this type of sound card, also please point me to the ALSA driver reference code for this type of sound card. -- Thanks, Sekhar

[PATCH 00/11] dmaengine: kill off dma_slave_config->slave_id
by Arnd Bergmann 25 Nov '21

25 Nov '21

From: Arnd Bergmann <arnd(a)arndb.de> I recently came across some new uses of the 'slave_id' field that I had (almost) removed a few years ago. There are no legitimate uses of this field in the kernel, only a few stale references and two drivers that abuse the field as a side-channel between the dmaengine driver and its client. Let's change the xilinx and qualcomm drivers to use the documented side-channel (peripheral_data) instead, and remove the remnants of it to prevent new users from coming in. As the last patch in the series depends on all the others, it would be nice have everything merged into the dmaengine tree for v5.17.

[PATCH] ALSA: hda/cs8409: Schedule delayed work for jack detect on resume
by Vitaly Rodionov 25 Nov '21

25 Nov '21

From: Stefan Binding <sbinding(a)opensource.cirrus.com> CS42L42 runs jack detect on resume, however this requires unsol events, and unsol events are ignored whilst the power state is not set to ON. The power state is set to ON only after the resume finishes. Schedule a delayed work timer to run jack detect after the resume call finishes.

[PATCH v2] ASoC: rockchip: i2s_tdm: Dup static DAI template
by Nicolas Frattaroli 25 Nov '21

25 Nov '21

Previously, the DAI template was used directly, which lead to fun bugs such as "why is my channels_max changing?" when one instantiated more than one i2s_tdm IP block in a device tree. This change makes it so that we instead duplicate the template struct, and then use that.

[PATCH v2 1/3] ASoC: SOF: sof-audio: setup sched widgets during pipeline complete step
by Kai Vehmanen 24 Nov '21

24 Nov '21

From: Pierre-Louis Bossart <pierre-louis.bossart(a)linux.intel.com> Older firmware prior to ABI 3.19 has a dependency where the scheduler widgets need to be setup last. Moving the call to sof_widget_setup() before the pipeline_complete() call also helps remove the need for the 'reverse' direction when walking through the widget list - this was only working because of the topology macros but the topology does not require any order.

[PATCH v4 0/4] ASoC: SOF: Intel: power optimizations with HDaudio SPIB register
by Pierre-Louis Bossart 24 Nov '21

24 Nov '21

This patchset was initially provided in a larger series that was split in two [1]. This part only provides support for the SPIB register support, added on Intel platforms since Skylake (2015). The use of the SPIB register helps reduce power consumption - though to a smaller degree than DMI_L1. This hardware capability is however incompatible with userspace-initiated rewinds typically used by PulseAudio. In the past (2015..2017) Intel suggested an API extension to let applications disable rewinds. At the time the feedback was that such a capability was too Intel-specific and SPIB remained unused except for loading DSP code. We now see devices with smaller batteries being released, and it's time to revisit Linux support for SPIB to extend battery life. In this update the rewinds are disabled via an opt-in kernel parameter. In the previous reviews, there was consensus that a Kconfig option was too complicated for distributions to set, and we are missing a TBD API to expose such capabilities to user-space. The debate on whether or not to use rewinds, and the impact of disabling rewinds, will likely be closed when Intel releases the 'deep-buffer' support, currently under development [2][3]. With this solution, rewinds will not be needed, ever. When an application deals with content that is not latency-sensitive (e.g. music playback), it will be able to reduce power consumption by selecting a different PCM device with increased buffering capabilities. Low-latency streams will be handled by the 'regular' path. In other words, the impossible compromise between power and latency will be handled with different PCM devices/profiles for the same endpoint, and we can push the design of capability negotiation to a later time when all the building blocks (firmware topology, kernel, userspace) are ready - we still have firmware xruns, DPCM race conditions to solve, and a need to describe these alternate PCM devices with UCM using 'modifiers'.
