[Sound-open-firmware] [PATCH] topology: ssp: add polarity inversion option in SSP_CLOCK
by Dragos Tarcatu 25 Feb '19

25 Feb '19

alsatplg allows setting inverted bclk and fsync polarities by setting either bclk_invert or fsync_invert to "true". This patch adds a default parameter in the SSP_CLOCK m4 macro which allows setting inverted bclk and fsync polarities.

After spending a bit more time on this, I agree it's possible to retrieve the required information without any change to the rtd structure. There are existing precedents using substream->runtime->private_data, e.g. to store an HDAudio stream tag, and SOF already has a list of contexts that can be searched for with a simple list walk. Modeling the DSP differently is something I'll add to my growing-by-the-day TODO list.

Thanks Arnaud for sharing this information. You made my day. We've had to deal with a number of hurdles related to platform and tools availability, so it's good news indeed if there are more platforms endorsing SOF. > This is a very good point, especially with people actually jumping on it > if we can avoid having multiple ABIs to worry about that would make life > a lot easier.

At a high level we only have very generic send/receive IPC messages, and it really shouldn't matter how the transport happens. However the actual contents/semantics of the messages do matter, and I'll have to run a check to make sure it scales.

I haven't found any time to look into this so for now left the code as is. Sparse is a useful tool for the address checks (topology/DMAs with _le32, __iomem, etc), the fewer warnings we get the better.

Sorry Mark, I am struggling with the 'first class' idea. Allow me to go back to the practical issue we faced here, and maybe/hopefully this will help us converge on a consensus. The only reason for extending the struct snd_soc_pcm_runtime was to enable the use of a 'context' in PCM operations, see e.g in patch 5/14 the repeated pattern to get an 'SOF PCM' context: struct snd_sof_pcm *spcm = rtd->private; Managing a context for PCM ops is typically done in other drivers by using the substream->private_data aka snd_pcm_substream_chip(substream). In ASoC/DPCM, unfortunately this substream->private_data field was reclaimed to store a pointer to a 'struct snd_soc_pcm_runtime', see e.g. in soc-pcm.c: pcm->private_data = rtd; if (playback) pcm->streams[SNDRV_PCM_STREAM_PLAYBACK].substream->private_data = rtd; if (capture) pcm->streams[SNDRV_PCM_STREAM_CAPTURE].substream->private_data = rtd; So ironically in ASoC we don't have a means to use a private_data field for the substreams since it's used for a 'standard' mechanism. The extension suggested in this patch 1/14 was really trying to come back to a practical means to store a context in a substream, and make the PCM operations manageable. I totally agree that extending the PCM runtime might not recommended or safe, but at this point I don't have any slack in the existing data structures to add a context in a substream. Does this help clarify the problem statement?

I see your point and agree the current direction isn't scalable, but I am not sure about the definition of 'first class device'. Did you mean 'component' at the same level as the 'platforms' and 'codecs', with all the DSP stuff nicely packaged and maintained in a self-contained way? Or a subcomponent that might be part of those platforms and codecs?

[Sound-open-firmware] [PATCH v4 00/14] ASoC: Sound Open Firmware (SOF) core
by Pierre-Louis Bossart 18 Feb '19

18 Feb '19

Sound Open Firmware (SOF) is a host and DSP architecture agnostic audio DSP firmware. SOF is not tied to any specific host architecture or any specific physical IO communication type (it will work with on SoC DSPs, or DSP connected via SPI/I2C). SOF is also not coupled to any particular DSP architecture and has abstraction similar to Linux to allow porting to other DSP architectures. https://www.sofproject.org/ This patch series introduces the SOF core and utilities. Support for Intel devices is provided as a follow-up series. The SOF core manages all the core DSP services and ALSA/ASoC IO. The core is responsible for loading firmware, parsing topology, exposing PCMs and kcontrols, providing debug and trace mechanisms and performing IPC between host and DSP. The SOF core also has logic to allow reuse of existing machine drivers for other platforms/machines without any code modification. i.e. DAI links can be modified at runtime to bind with SOF and SOF topologies instead of existing hard coded DAI links and topology. Changes since v3: Addressed dozens ofcomments from Takashi Iwai, Mark Brown, Andy Shevchenko, Daniel Baluta (Thanks!) Hardened memory allocation, fixed module load/unload oops or errors (now at hundreds of cycles on ApolloLake devices) Fixed suspend/resume and removed use of suspend_late, now using snd_soc_pm_ops and standard flow Fixed topology free (multiple patches already contributed for ASoC-core) Fixed debugfs/pm_runtime interaction Removed error checks on debugfs, changed to EXPORT_SYMBOL_GPL Added filenames in debug messages, ues hex_dump_to_buffer Removed "sof-audio" platform device and added better error checks on probe Reworked data structures to remove mix of const/variable fields and duplication of pointers for platform-specific changes Removed redundant ops tables Fixed trace/logger issues Fixed issues with loader (alignment and block size errors) Fixed release_firmware handling (was all over the place) Simplified PCI handling Added comments on non-atomic triggers Removed enum controls (not supported in topology) Simplified include file dependencies Fix cppcheck warnings Fixed Kconfigs to deal with Kbuild warnings on exotic architectures Precisions: The code in this patchset is directly squashed from the SOF development branch [1], which tracks Mark Brown's for-next branch on a weekly basis and the configurations used for testing are based on the defconfigs at [2]. The patches are also used backported for Chromebook devices. Full disclosure on known limitation and issues (full list at [3]) a) the interaction with ASoC is not always perfect, there are a couple of points where a better solution is desired (use of private data, support for link DMA, etc). The known points are explicitly documented in the code and will be updated. To be clearer, it's our belief that SOF does not cripple ASoC in any way, and that merging this SOF core does not harm others. It's just complicated to get things right, especially on a couple of cases where the topology and DPCM frameworks generate complex flows that very few people understand. b) The get/put methods for controls generate an IPC and possibly a wake-up. This is not optimal and is being fixed. c) runtime_pm is being hardened and the use of SMART_SUSPEND was suggested. Thank you for reviews and comments, we appreciate the time spent commenting on this large patchset. Thanks in particular to Alan Cox and Andy Shevchenko for their comments on an earlier version. This patchset also includes contributions from Daniel Baluta for loading code on non-Intel platforms.

[Sound-open-firmware] Design document - topology, scheduling et all
by Daniel Baluta 14 Feb '19

14 Feb '19

Hi all, First of all I'm now in the phase where I only need to implement the DMA driver for i.MX and create the topology file. Few questions: 1) Is there any simple scenario (topology file) where I could test that scheduling, ipc, pipelines, etc works without the DMA? It is my first time using topology and I'm still yet to get around the m4 topology description. 2) Is there any design document for the SOF architecture. I'm still yet to understand how components and scheduler interact. thanks, Daniel.

[Sound-open-firmware] [PATCH v2 00/20] ASoC: Sound Open Firmware (SOF) - Intel support
by Pierre-Louis Bossart 14 Feb '19

14 Feb '19

This patch series introduces the support for Intel devices (Baytrail, CherryTrail, Broadwell/Haswell, ApolloLake, GeminiLake, CannonLake, IceLake). Support for Skylake and KabyLake is incomplete at the moment but the basic building blocks required are already present. The series starts with the 'legacy' devices, then all the more recent ones and concludes with ACPI/PCI hooks. SKL+ platforms can be compiled without HDaudio link/codec support, in which case the hdac library is not used. When support for HDMI or HDaudio codecs is selected, parts of this library are used. The machine drivers supported by SOF are not provided as part of this series. The build will only work in 'nocodec' mode for now. Support for SPI-based devices, compressed streams is also not provided for now since it's not ready for upstream just yet. Thank you for reviews and comments, we appreciate the time spent commenting on this large patchset. Thanks in particular to Alan Cox and Andy Shevchenko for their comments on an earlier version. Changes since v2: Addressed dozens of comments from Takashi Iwai, Mark Brown, Andy Shevchenko, Daniel Baluta (Thanks!)

[Sound-open-firmware] SOF/Intel: change of directory structure for firmware binaries
by Pierre-Louis Bossart 08 Feb '19

08 Feb '19

FYI, if anyone uses the latest SOF kernel branch (topic/sof-dev), there was a change in the location of the files used by the Linux kernel for Intel platforms: firmware files are by default in /lib/firmware/intel/sof topology files are in /lib/firmware/intel/sof-tplg. You can override this by adding module arguments to go back to the previous setup. modprobe sof-[pci|acpi]-dev fw_path=intel tplg_path=intel This change was made so that firmware and topologies can be released separately, and allow a contributor company to release support for multiple platforms at the same time, with symlinks used for the directories instead of individual files. It'll also help distros or OEMs use non-default firmware locations for their own releases, if they included non-public components or change the firmware configurations. Sorry for the inconvenience in the transition. -Pierre

Hello, this is the first post from a newb user so first of all kudos to everyone for this amazing project. I have followed the build from scratch instructions and built successfully the apl firmware (from branch master), but am having trouble building the unit tests: :~/lara/sof/sof/build_ut$ cmake -DTOOLCHAIN=xtensa-apl-elf -DROOT_DIR=`pwd`/../../xtensa-root/xtensa-apl-elf -DBUILD_UNIT_TESTS=ON .. -- Preparing Xtensa toolchain -- Configuring done -- Generating done -- Build files have been written to: /home/antonis/lara/sof/sof/build_ut :~/lara/sof/sof/build_ut$ make apollolake_defconfig [100%] Applying olddefconfig with apollolake_defconfig Using existing configuration '.config' as base Configuration written to '.config' [100%] Built target apollolake_defconfig :~/lara/sof/sof/build_ut$ make -j4 -- Preparing Xtensa toolchain -- Configuring done -- Generating done -- Build files have been written to: /home/antonis/lara/sof/sof/build_ut [ 0%] Built target ld_script_memory_mock [ 0%] Performing update step for 'cmocka_git' [ 0%] Generating /home/antonis/lara/sof/sof/build_ut/generated/include/config.h [ 0%] Built target genconfig Scanning dependencies of target audio_for_volume [ 0%] Building C object test/cmocka/src/audio/volume/CMakeFiles/audio_for_volume.dir/__/__/__/__/__/src/audio/volume_generic.c.o [ 2%] Building C object test/cmocka/src/audio/volume/CMakeFiles/audio_for_volume.dir/__/__/__/__/__/src/audio/volume.c.o [ 2%] Building C object test/cmocka/src/audio/volume/CMakeFiles/audio_for_volume.dir/__/__/__/__/__/src/audio/volume_hifi3.c.o [ 3%] Linking C static library libaudio_for_volume.a [ 3%] Built target audio_for_volume Current branch master is up to date.
