6c393ebb - ASoC: SOF: core: Implement IPC version fallback if firmware files are missing

Wed, 29 Nov 2023 12:53:27 +0000

ASoC: SOF: core: Implement IPC version fallback if firmware files are missingIf a firmware file is missing for the selected IPC type then try to switchto other supported IPC type and check if that one can be used instead.If for example a platform is changed to IPC4 as default version but thegiven machine does not yet have the needed topology file created then wewill fall back to IPC3 which should have all the needed files.Relocate the sof_init_environment() to be done at a later phase, insof_probe_continue().This will only have changes in behavior ifCONFIG_SND_SOC_SOF_PROBE_WORK_QUEUE is enabled (Intel HDA platforms) bynot failing the module probe, but it is not going to be different casecompared to for example failed firmware booting or topology loading error.Signed-off-by: Peter Ujfalusi Reviewed-by: Kai Vehmanen Link: https://lore.kernel.org/r/20231129125327.23708-14-peter.ujfalusi@linux.intel.comSigned-off-by: Mark Brown List of files: /linux-6.15/sound/soc/sof/Kconfig

4bd1adb8 - ASoC: SOF: introduce new DEBUG_NOCODEC mode

Thu, 27 Oct 2022 19:35:40 +0000

ASoC: SOF: introduce new DEBUG_NOCODEC modeThe existing NOCODEC mode enforces a build-time mutual exclusion withthe HDaudio link support, mostly to avoid any dependency on thesnd_hdac library and references to HDAudio codec/i915 stuff.This is very useful to track dependencies and test a minimalconfiguration, but very painful for developers and CI: a recompilationand reinstall of the kernel modules is required.This patch suggests an alternate middle ground where the selection ofthe machine driver and all codec-related actions are bypassed atrun-time, contingent on a kernel module parameter being set.For example setting BIT(10) with'options snd_sof sof_debug=0x401'is enough to switch from an HDaudio card to a nocodec one.This new DEBUG_NOCODEC mode is not suitable for distributions andend-users. It's not even recommended on all platforms, i.e. theNOCODEC mode is known not to work on specific devices where the BIOSdid not configure support for I2S/DMIC interfaces. The usualdevelopment devices such as Chromebooks, Up boards and Intel RVP arethe only recommended platforms where this mode can be supported.Note that the dynamic switch between HDaudio and nocodec may notalways possible depending on hardware layout, pin-mux options, andBIOS settings. The audio subsustems on Intel platforms has to support4 types of interfaces and pin-mux can be complicated.Reviewers might ask: why didn't we do this earlier? The main reason isthat all the codec-related configurations were not cleanly separatedout in the sof/intel directory. With all the cleanups done recently,adding this opt-in behavior is relatively straightforward.Tested on UpExtreme (WHL) and UpExtreme i11 (TGL).Signed-off-by: Pierre-Louis Bossart Reviewed-by: Rander Wang Reviewed-by: Bard Liao Reviewed-by: Péter Ujfalusi Reviewed-by: Ranjani Sridharan Link: https://lore.kernel.org/r/20221027193540.259520-22-pierre-louis.bossart@linux.intel.comSigned-off-by: Mark Brown List of files: /linux-6.15/sound/soc/sof/Kconfig

6955d951 - ASoC: SOF: Introduce IPC SOF client support

Thu, 10 Feb 2022 15:05:21 +0000

ASoC: SOF: Introduce IPC SOF client supportA client in the SOF (Sound Open Firmware) context is a driver that needsto communicate with the DSP via IPC messages. The SOF core is responsiblefor serializing the IPC messages to the DSP from the different clients.One example of an SOF client would be an IPC test client that floods theDSP with test IPC messages to validate if the serialization works asexpected.Multi-client support will also add the ability to split the existing audiocards into multiple ones, so as to e.g. to deal with HDMI with a dedicatedclient instead of adding HDMI to all cards.This patch introduces descriptors for SOF client driver and SOF clientdevice along with APIs for registering and unregistering a SOF clientdriver, sending IPCs from a client device and accessing the SOF coredebugfs root entry.Along with this, add a couple of new members to struct snd_sof_dev thatwill be used for maintaining the list of clients.Signed-off-by: Ranjani Sridharan Co-developed-by: Fred Oh Signed-off-by: Fred Oh Signed-off-by: Peter Ujfalusi Reviewed-by: Kai Vehmanen Reviewed-by: Pierre-Louis Bossart Reviewed-by: Ranjani Sridharan Link: https://lore.kernel.org/r/20220210150525.30756-6-peter.ujfalusi@linux.intel.comSigned-off-by: Mark Brown List of files: /linux-6.15/sound/soc/sof/Kconfig
