[RFC PATCH] soundwire: bus: use correct driver name in error messages
by Pierre-Louis Bossart 08 Feb '21

08 Feb '21

None of the existing codec drivers set the sdw_driver.name, but instead set sdw_driver.driver.name. This leads to error messages such as [ 23.935355] rt700 sdw:2:25d:700:0: Probe of (null) failed: -19 We could remove this sdw_driver.name if it doesn't have any purpose. This patch only suggests using the proper indirection.

[PATCH v2] ALSA: hda: intel-dsp-config: Add SND_INTEL_BYT_PREFER_SOF Kconfig option
by Hans de Goede 08 Feb '21

08 Feb '21

The kernel has 2 drivers for the Low Power Engine audio-block on Bay- and Cherry-Trail SoCs. The old SST driver and the new SOF driver. If both drivers are enabled then the kernel will default to using the old SST driver, unless told otherwise through the snd_intel_dspcfg.dsp_driver module-parameter. Add a boolean SND_INTEL_BYT_PREFER_SOF Kconfig option, which when set to Y will make the kernel default to the new SOF driver instead. The option defaults to n, preserving the current behavior. Making this configurable will help distributions such as Fedora: https://fedoraproject.org/w/index.php?title=Changes/SofDefaultForIntelLpe to test using SOF on BYT/CHT during the transition phase where we have both drivers (eventually the old driver and this option will be removed). Note that this drops the acpi_config_table[] containing 2 entries per ACPI hardware-id if both drivers are enabled. snd_intel_acpi_dsp_find_config() will always return the first hit, so we only need a single entry with the flags value set depending on the Kconfig settings.

[PATCH] ALSA: fireface: fix to parse sync status register of latter protocol
by Takashi Sakamoto 08 Feb '21

08 Feb '21

Fireface UCX, UFX, and FF802 are categorized for latter protocol of the series. Current support for FF802 (and UFX) includes failure to parse sync status register and results in EIO. Further investigation figures out that the content of register differs depending on models. This commit adds tables specific to FF802 and UFX to fix it.

[PATCH v2 0/3] ALSA: hda: add link_power op to hdac_bus_ops
by Kai Vehmanen 08 Feb '21

08 Feb '21

Here's the 2nd iteration of the patch to improve link management granularity between controllers using HDA extended bus and HDA codec drivers. Based on feedback to V1, this now adds a new link_power op. This allows to decouple HDA codec drivers from the hdac_ext core. I also included two patches to SOF to show how this interface is used in SOF.

[PATCH 0/2] soundwire: add DMI quirks to work-around broken _ADR
by Pierre-Louis Bossart 08 Feb '21

08 Feb '21

Unfortunately the DSDT often exposes _ADR information which reports the presence of the wrong codecs, which prevents drivers from being probed, or they are reported on the wrong link, which breaks the ASoC machine driver. This patchset suggests a device-specific remapping to the expected values reported by codecs, controlled by a DMI check. Adding such quirks in the kernel code is ugly, but for commercial devices it's certainly better than asking every user to override the DSDT.

[PATCH 1/2] ALSA: hda: intel-dsp-config: Add FLAG_BYT_FIRST / _SECOND defines
by Hans de Goede 08 Feb '21

08 Feb '21

Instead of hardcording the SST driver having the highest prio, add FLAG_BYT_FIRST and FLAG_BYT_SECOND defines, which get set like this when both drivers are enabled: #define FLAG_BYT_FIRST FLAG_SST #define FLAG_BYT_SECOND FLAG_SOF And when only 1 driver is enabled then FLAG_BYT_FIRST gets set to the flag for that driver. This is a preparation patch for making which driver is preferred configurable through Kconfig.

[PATCH v2 0/9] ALSA: add virtio sound driver
by Anton Yakovlev 08 Feb '21

08 Feb '21

This series implements a driver part of the virtio sound device specification v8 [1]. The driver supports PCM playback and capture substreams, jack and channel map controls. A message-based transport is used to write/read PCM frames to/from a device. The series is based (and was actually tested) on Linus's master branch [2], on top of commit 1e2a199f6ccd ("Merge tag 'spi-fix-v5.11-rc4' of ...") As a device part was used OpenSynergy proprietary implementation. Any comments are very welcome. v1->v2 changes: 1. For some reason, in the previous patch series, several patches were squashed. Fixed this issue to make the review easier. 2. Added mst(a)redhat.com to the MAINTAINERS. 3. When creating virtqueues, now only the event virtqueue is disabled. It's enabled only after successful initialization of the device. 4. Added additional comments to the reset worker function: [2/9] virtio_card.c:virtsnd_reset_fn() 5. Added check that VIRTIO_F_VERSION_1 feature bit is set. 6. Added additional comments to the device removing function: [2/9] virtio_card.c:virtsnd_remove() 7. Added additional comments to the tx/rx interrupt handler: [5/9] virtio_pcm_msg.c:virtsnd_pcm_msg_complete() 8. Added additional comments to substream release wait function.

[PATCH] ASoC: SOF: debug: Fix a potential issue on string buffer termination
by Hui Wang 08 Feb '21

08 Feb '21

The function simple_write_to_buffer() doesn't add string termination at the end of buf, we need to add it on our own if calling that function to write the size of count chars to buf. This change refers to the function tokenize_input() in debug.c and the function sof_dfsentry_trace_filter_write() in trace.c. We didn't find this potential issue in the past because sometimes we are very lucky, we kzalloc the size of count buf, the kernel not only returns a buf with buf[0 ... (count - 1)] = 0 but buf[count] = 0, with this luck, this issue will not be exposed.

[PATCH 0/7] Add audio driver base on rpmsg on i.MX platform
by Shengjiu Wang 07 Feb '21

07 Feb '21

On Asymmetric multiprocessor, there is Cortex-A core and Cortex-M core, Linux is running on A core, RTOS is running on M core. The audio hardware device can be controlled by Cortex-M device, So audio playback/capture can be handled by M core. Rpmsg is the interface for sending and receiving msg to and from M core, that we can create a virtual sound on Cortex-A core side. A core will tell the Cortex-M core sound format/rate/channel, where is the data buffer, what is the period size, when to start, when to stop and when suspend or resume happen, each of this behavior there is defined rpmsg command. Especially we designed the low power audio case, that is to allocate a large buffer and fill the data, then Cortex-A core can go to sleep mode, Cortex-M core continue to play the sound, when the buffer is consumed, Cortex-M core will trigger the Cortex-A core to wakeup to fill data.
