[Sound-open-firmware] [PATCH 0/3] ASoC: SOF: VirtIO: preparatory patches
by Guennadi Liakhovetski 10 Feb '20

10 Feb '20

This is the first set of patches for the SOF virtualisation work. We send these patches first because they touch the ASoC core. 2 of them are mostly cosmetic with no functional changes, but patch 2/3 might cause some discussions. Please review and comment. Thanks Guennadi Guennadi Liakhovetski (3): ASoC: (cosmetic) simplify dpcm_prune_paths() ASoC: add function parameters to enable forced path pruning ASoC: export DPCM runtime update functions include/sound/soc-dpcm.h | 30 +++++++++-- sound/soc/soc-compress.c | 2 +- sound/soc/soc-dapm.c | 8 +-- sound/soc/soc-pcm.c | 126 ++++++++++++++++++++++++++++++----------------- 4 files changed, 112 insertions(+), 54 deletions(-) -- 1.9.3

[Sound-open-firmware] Distribution of sof firmware and tplg files
by Daniel Baluta 07 Feb '20

07 Feb '20

Hi Liam, Pierre, Jaroslav, I know there were a lot of discussions about distribution of SOF firmware and tplg files and I would like to have a conclusion here and also validate that I understood it correctly. Simplified view: * sof firmware will go to https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git * tplg files will go to https://github.com/alsa-project/alsa-topology-conf/pull/1 Is that correct, right? I'm asking this in the context of integrating the binaries with Yocto where we have two options: * build everything from sources (1) * pull the binaries from repos mentioned above (2) Option (1) is a little bit trickier because of Xtensa toolchain license. So, the easiest option for us wuold be (2). Is there a versioning scheme for linux-firmware and alsa-topology? Daniel.

[Sound-open-firmware] Jenkins CI is down - possibly into next week.
by Liam Girdwood 29 Jan '20

29 Jan '20

Some of the SOF project's Jenkins CI infrastructure is located in Shanghai and is currently down. It subsequently may not be possible in the short term to power cycle Jenkins CI (and the DUTs) due to government health and travel advice in the Shanghai enterprise area (as a result of the Coronavirus outbreak). The current restrictions are due to be lifted around February the 10th, but I'm hoping we can recover Jenkins before this. Maintainers in the meantime should only rely on Internal CI and Travis results until Jenkins is back (it's currently just showing as pending). Thanks Liam

[Sound-open-firmware] Error compiling SOF with newer Xtensa configuration
by Daniel Baluta 21 Jan '20

21 Jan '20

Hello Liam, Tomasz, We are trying to upgrade the toolchains (gcc/xtensa) based on RI-2019.1-linux. Anyhow, we are hitting the following error: /work/repos/sof/sof/src/arch/xtensa/xtos/core-restore.S: Assembler messages: /work/repos/sof/sof/src/arch/xtensa/xtos/core-restore.S:241: Error: unknown opcode or format name 'addi.a' I wonder if you met this kind of error before at toolchain upgrade. I suspect that something has changed and we somehow need to update the xtos/ directory too. Daniel.

[Sound-open-firmware] SOF audio processing components - status of AEC
by Daniel Baluta 17 Jan '20

17 Jan '20

Hi Seppo, Any idea what is the status of AEC component from SOF audio processing components development list? More than that, I don't expect Intel to release a binary for such an algorithm but I would like to understand how this fits inside SOF? Do you use special component? thanks, Daniel.

[Sound-open-firmware] FYI: SOF for i.MX8 at Google Summer of Code
by Daniel Baluta 16 Jan '20

16 Jan '20

Hello everyone, I've created a special entry for SOF into Linux Foundation GSoC proposal. https://wiki.linuxfoundation.org/gsoc/2020-gsoc-sound-open-firmware I remember last year Intel had their own proposal for SOF. We can still go like this, but just wanted to let you know that my proposal is under Linux Foundation page. If you have any ideas you can add them to the page. thanks, Daniel.

[Sound-open-firmware] [SOF CI] SOF CI Jenkins will be unstable from Jan.13 to Jan.15
by Pan, Xiuli 13 Jan '20

13 Jan '20

Hi all, sof-ci/jenkins/ will be unstable for few days due to power maintenance in our server room. Please expect slow feedback and failing test results from Jenkins. Travis and Internal Intel CI System will not be influenced. Thanks Xiuli
