28 Aug '19

From: Maxime Ripard <maxime.ripard(a)bootlin.com> Even though the H6 compatible has been properly added, the exeption for the number of DMA channels hasn't been updated, leading in a validation warning.

[alsa-devel] [BUG] bdw-rt5650 DSP boot timeout
by Jon Flatley 28 Aug '19

28 Aug '19

I've been working on upstreaming the bdw-rt5650 machine driver for the Acer Chromebase 24 (buddy). There seems to be an issue when first setting the hardware controls that appears to be crashing the DSP: [ 51.424554] haswell-pcm-audio haswell-pcm-audio: FW loaded, mailbox readback FW info: type 01, - version: 00.00, build 77, source commit id: 876ac6906f31a43b6772b23c7c983ce9dcb18a19 ...

The other 50% of the time the DSP comes up just fine and audio works fine thereafter. Adding "#define DEBUG 1" to sound/soc/intel/haswell/sst-haswell-ipc.c makes the issue occur much less frequently in my testing. Seems like a subtle timing issue. There were timing issues encountered during the bringup of the 2015 chromebook pixel (samus) which uses the bdw-rt5677 machine driver. Those were slightly different, and manifested during repeated arecords. Both devices use the same revision of the sst2 firmware. Any ideas for how to debug this? Thanks, Jon

[alsa-devel] [RESEND PATCH v4 0/4] ASoC: codecs: Add WSA881x Smart Speaker amplifier support
by Srinivas Kandagatla 27 Aug '19

27 Aug '19

Resending this series due to a typo in yaml filename! Thanks for reviewing v3 patchset, here is v4 with addressing the comments in v3 This patchset adds support to WSA8810/WSA8815 Class-D Smart Speaker Amplifier which is SoundWire interfaced. This also adds support to some missing bits in SoundWire bus layer like Device Tree support. This patchset along with DB845c machine driver and WCD934x codec driver has been tested on SDM845 SoC based DragonBoard DB845c with two WSA8810 speakers. Most of the code in this driver is rework of Qualcomm downstream drivers used in Andriod. Credits to Banajit Goswami and Patrick Lai's Team. TODO: Add thermal sensor support in WSA881x.

[alsa-devel] Applied "ASoC: sunxi: Revert initial A83t support" to the asoc tree
by Mark Brown 27 Aug '19

27 Aug '19

The patch ASoC: sunxi: Revert initial A83t support has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail.
