[Sound-open-firmware] [PATCH v3 0/5] Add DSP node for i.MX8QXP board to be used by DSP SOF driver
by Daniel Baluta 07 Aug '19

07 Aug '19

i.MX 8QXP boards feature an Hifi4 DSP from Tensilica. This patch series aims on adding the DT node describing the DSP, but it also contains the Linux SOF DSP driver code that will use the DT node for easier review. Note that we switched to the new yaml format for bindings documentation. The DSP will run SOF Firmware [1]. Patches 1,2,3 are adding support for Linux DSP driver are already sent for review to SOF folks [2] Ideally, patches 4/5 and 5/5 will go upstream through Shawn's tree while 1-3/5 will go upstream via Pierre's tree -> ASoC tree. Mind that SOF DSP support depends on IMX DSP communication protocol up for review here: https://lkml.org/lkml/2019/8/1/260 Shawn, can you pick this up first? Symbol dependencies are hopefully set correct so even if one of the patches is not in a tree the compilation will not fail because the symbols depending on that patches will not be selected.

[Sound-open-firmware] host_dma_cb() error: Wrong callback type = 3
by Paul Olaru 06 Aug '19

06 Aug '19

Hello, I'm currently implementing the DMA driver for the IMX platform (Dummy DMA). With this partial implementation I have noticed the error message in the title. The thing is, within host.c I see that dma_set_cb is called with the type as DMA_CB_TYPE_IRQ | DMA_CB_TYPE_COPY (which is 3), yet in host_dma_cb itself I only see the cases for these bits individually, and it falls into the default case. I've also noticed this in the dai.c file.

[Sound-open-firmware] Signed firmware availability for kbl/cnl
by Daniel Drake 05 Aug '19

05 Aug '19

Hi, Thanks for all the hard work on SOF! We are hoping to try it on consumer products in order to support the internal digital mic, which is not supported when running in HDA mode. Specifically Acer AIO Aspire Z24-890 (Intel i3-8100T) and ASUS MJ401TA (Intel m3-8100Y) are two models we have in hand right now. I gather from previous discussions that even though the sof source code is public, the resultant binary files need to be signed by Intel before they can be used. Is that correct? If so, when will these be made available? The files that Linux 5.2 is looking for here are: sof-cnl.ri sof-cnl-nocodec.tplg sof-kbl.ri sof-kbl-nocodec.tplg Thanks

A subsequent commit would have added the community signed images. I planned to link community signed binaries at the intel/sof/community level since most users would use the production signed images by default (and would not need to use a module param to select). My assumption was that machines using community signed by default would have this in their default_fw_path ? > > > > I guess we need to talk off-line since we are evidently not on the > > same > > page or something is missing for people to use this pull request. > > I suggest you guys do that.

Yep, no problem - Pierre and I will refine and resend shortly. I also need to remove links for aliases. Thanks Liam

[Sound-open-firmware] Audio miniconf + sof meeting at ELCE, Lyon
by Daniel Baluta 31 Jul '19

31 Jul '19

Hi Mark, Pierre, Liam, Ranjani, Will you be in Lyon for ELCE this year? I'm very interested in participating to an (eventual) audio miniconf meeting. Maybe we can also do a separate SOF meeting if they are enough people interested.

[Sound-open-firmware] Questions about the SOF coredump reader
by Paul Olaru 26 Jul '19

26 Jul '19

I'm trying to diagnose a few issues on the IMX platform and it would be nice if I would be able to interpret panics and exceptions. I have just fixed a minor issue so that the debugfs "exception" entry is correct. I would like to know if the tool in sof/tools/coredumper/sof-coredump-reader.py is usable for interpreting such dumps and how it should be used. Right now, I have inserted a "panic" call in my code (that makes a dump which seems to be in the proper format), but whenever I try to run this tool on that /sys/kernel/debug/sof/exception file it gets exceptions (one about exccause and, if I remove the corresponding code, it messes up the pathname interpretation too, complaining about UTF-8 being invalid - I suspect wrong offsets?). So, how is this tool supposed to be used?

[Sound-open-firmware] Linux build for arm64
by Daniel Baluta 18 Jul '19

18 Jul '19

Hi Liam / Pierre, Could we add a build for arm64 too in CI? With recent patches that add support for i.MX8 SOF Linux driver it would be handy to also have the build for arm64. I can help you with the cross-compilers and build instructions. Currently we are only building for x86_64. https://travis-ci.org/thesofproject/linux/builds/560509972 thanks, Daniel.

[Sound-open-firmware] New platform bringup docs
by Curtis Malainey 11 Jul '19

11 Jul '19

Hello SOF community, Do we have any documents similar to the new architecture links (https://thesofproject.github.io/latest/architectures/dsp/index.html#adding-…) but more advanced. I was thinking ideally something along the lines of a check/worklist of features to be built for introducing a new platform to SOF. Daniel you have done this, do you have any documents or experiences that we can turn into a doc? Thanks in advance. Curtis
