[Sound-open-firmware] Default branch for rimage repo
by Daniel Baluta 04 Aug '21

04 Aug '21

Hi Liam and Marc, What is the default branch used by SOF project for rimage submodule? I think the sof build system still uses master branch while we pushed our PR on main. Is that true? Also, should we manually update the rimage repo to look for changes or cmake build scripts do this automatically. Daniel.

[Sound-open-firmware] Dynamic module loading
by Daniel Baluta 30 Jul '21

30 Jul '21

Hi Rander, Regarding your patch: https://github.com/thesofproject/sof/pull/4536/commits/12ca2c956e5be4949e61… We've seen this new IPC: case SOF_IPC4_GLB_LOAD_MULTIPLE_MODULES: case SOF_IPC4_GLB_UNLOAD_MULTIPLE_MODULES: tr_err(&ipc_tr, "not implemented ipc message type %d", type); ret = IPC4_UNAVAILABLE; Is this loading a new binary module for SOF to later use? Is there any documentation about this? Or a pointer in the converged-modules repo? We are working on implementing a similar feature and we could use and work previously done. thanks, Daniel.

Hi Seppo, Is there any documentation on how to use the Equalizer component for SOF? Is there any way to dynamically change the coefficients at runtime?

[Sound-open-firmware] question: status sound on Intel NUC M15
by Gilles van Eeden 12 Jul '21

12 Jul '21

Hi, hopefully this is the right place for this question. I've fruitlessly been trying to get sound to work on the Intel NUC M15 <https://linux-hardware.org/?probe=93690f8eec>. A fitting topology for this platform seems lacking, among other things. Is there any work ongoing on this? I will gladly provide diagnostic data from my system, if so desired. Best regards, Gilles

[Sound-open-firmware] Commit c80270e7e49 (" ipc: structures should all be aligned on 4 bytes") causes issues on i.MX8
by Daniel Baluta 11 May '21

11 May '21

Hi Liam, I noticed this SOF commit: commit c80270e7e49d26a34fe284d1868e7d9cb80104f1 Author: Liam Girdwood <liam.r.girdwood(a)linux.intel.com> Date: Sat Apr 3 21:22:21 2021 +0100 ipc: structures should all be aligned on 4 bytes Give the compiler a chance to further optimise IPC data access since it's all on a 4 byte alignment. Signed-off-by: Liam Girdwood <liam.r.girdwood(a)linux.intel.com> It looks like it triggers some issues on i.MX8. Is there any equivalent for Linux kernel? Some structures are shared with the kernel and on arm64 it assumes default alignment as 8 hence I get a mismatch at least when printing DAI / Host position + dev_info(sdev->dev, "posn : host 0x%llx dai 0x%llx wall 0x%llx no_per %d\n", + posn.host_posn, posn.dai_posn, posn.wallclock, stream->substream->runtime->no_period_wakeup); thanks, Daniel.

by Girdwood, Liam R 06 Apr '21

06 Apr '21

The SOF developers are pleased to announce that version 1.7 has been released and binaries available for Intel and NXP platforms[1]. The main focus of v1.7 was around adding support for new audio processing algorithms, continued Zephyr integration and general stabilisation. Release notes are here. https://github.com/thesofproject/sof/releases/tag/v1.7 Binaries are here. https://github.com/thesofproject/sof-bin Firmware issues can be reported here (and feature requests too). https://github.com/thesofproject/sof/issues and kernel issues here https://github.com/thesofproject/linux/issues The next version will be v1.8 due by the end of June. Thanks Liam [1] Preliminary support for other platforms can be enabled by using SOF as a Zephyr module (for Zephyr supported architectures and platforms). --------------------------------------------------------------------- Intel Corporation (UK) Limited Registered No. 1134945 (England) Registered Office: Pipers Way, Swindon SN3 1RJ VAT No: 860 2173 47 This e-mail and any attachments may contain confidential material for the sole use of the intended recipient(s).

[Sound-open-firmware] crosstool-ng branch sof-gcc8.1
by Daniel Baluta 02 Apr '21

02 Apr '21

Hi Liam, sof-gcc8.1 branch of crosstool-ng fails to build a cross compiler (i think for all platforms) because expat version 2.2.5 ( CT_EXPAT_VERSION="2.2.5" ) is vulnerable. https://sourceforge.net/projects/expat/files/expat/2.2.5/expat-2.2.5-RENAME… What's your take on this? Should we change the config files to upgrade expat to 2.3.0 or should we directly use newer versions of gcc. What gcc toolchain versions is Intel using? We at NXP want to align with that. thanks, Daniel.
