[alsa-devel] [RFC PATCH 0/6] ALSA/HDA: abort probe when DMICs are detected
by Pierre-Louis Bossart 18 Jun '19

18 Jun '19

This is the second take on same problem of detecting when the HDaudio legacy driver can be used and when the SST or SOF drivers are required. The previous attempt based on a the PCI Class information was a resounding failure and broke audio on Linus' laptop, so we need additional information to avoid enabling a DSP-based driver without a good reason to do so. This patchset suggests the use of the NHLT information which *in theory* exposes DMIC endpoints. The legacy HDaudio driver cannot handle DMICs and will not provide any capture capabilities. Since it's typically the first one to probe due to the Makefile order, aborting the probe will let the PCI subsystem look for the next driver which hopefully will support this capability. I tested this patch on 5 devices (SKL, KBL, APL, GLK, WHL), three without DMICs and two with, and the detection seems to work as planned. I would appreciate it if HDaudio integrators and folks at Google/Canonical/Endless can give this a try. As usual I expect that we will have to use quirks and work-arounds, but it'd be a better idea than a build-time mutual exclusion. We could also make this optional (Kconfig and/or module parameters) if people prefer to muck with blacklists. Feedback and comments welcome!

[alsa-devel] [PATCH 00/10] ALSA: firewire-motu: reserve/release isochronous resources in pcm.hw_params/hw_free callbacks
by Takashi Sakamoto 18 Jun '19

18 Jun '19

Hi, This patchset is the last part of patches for all of drivers in ALSA firewire stack to reserve/release isochronous resources in pcm.hw_params/hw_free callbacks, like the other patchsets: https://mailman.alsa-project.org/pipermail/alsa-devel/2019-June/150118.html https://mailman.alsa-project.org/pipermail/alsa-devel/2019-June/150863.html In current implementation, the resources are reserved at the same time to start packet streaming, and released at the same time to stop packet streaming. However, once allocated, the resources are available independent of lifetime of each of packet streaming. The isochronous resources are the resources of IEEE 1394 bus. On the other side of view, it's a kind of resources of hardware to maintain the bus (isochronous resource manager). For this kind of reservation and release, hw_params and hw_free operations are suitable in ALSA PCM interface. Ideally, the operation to reserve/release isochronous resource should be separated from the operation to start/stop packet streaming. However, IEEE 1394 bus has reset event. Once reset occurs, isochronous resource manager releases allocated resources. The resources should be reallocated by requesters themselves. For this reason, in this patchset, bus generation is checked before starting packet streaming. If generation is updated, reallocation is requested to isochronous resource manager, then packet streaming starts.

[alsa-devel] [PATCH v1 1/1] ASoC: rsnd: fixup mod ID calculation in rsnd_ctu_probe_

From: Nilkanth Ahirrao <anilkanth(a)jp.adit-jv.com> commit 7e4f3419ebfe ("ASoC: rsnd: add .get_id/.get_id_sub") introduces rsnd_ctu_id which calcualates and gives the main Device id of the CTU by dividing the id by 4. rsnd_mod_id uses this interface to get the CTU main Device id. But this commit forgets to revert the main Device id calcution previously done in rsnd_ctu_probe_ which also divides the id by 4. This path corrects the same to get the correct main Device id.

[alsa-devel] [PATCH 00/15] ASoC: SOF: Intel: HDaudio fixes and improvements
by Pierre-Louis Bossart 17 Jun '19

17 Jun '19

This is unfortunately a rather large patchset tied to hardware enablement. While productizing HDAudio+DMIC-based platforms, which is a common design starting with CoffeLake platforms, the SOF team encountered a combination of issues with host/link DMA coupling, interrupt handling and other bits not getting properly cleared. The patches in this series provide significant reliability and usage improvements. They are viewed as mandatory for any product based on HDaudio. There will be a smaller series to fix HDaudio wake. It's almost ready but didn't make the cut for this week and there's no reason to delay reviews on the main changes further. The remaining topics to complete are autodetection of the number of microphones, for which an ACPI-based solution exists, and autodetection of which platforms need to rely on a signed firmware, for which DMI quirks will be required. This will be provided later in July (after travel+vacation break for a number of contributors).
