[PATCH AUTOSEL 6.8 06/98] ASoC: SOF: amd: Optimize quirk for Valve Galileo
by Sasha Levin 29 Mar '24

29 Mar '24

From: Cristian Ciocaltea <cristian.ciocaltea(a)collabora.com> [ Upstream commit a13f0c3c0e8fb3e61fbfd99c6b350cf9be0c4660 ] Valve's Steam Deck OLED is uniquely identified by vendor and product name (Galileo) DMI fields. Simplify the quirk by removing the unnecessary match on product family. Additionally, fix the related comment as it points to the old product variant.

[PATCH AUTOSEL 6.6 19/21] ASoC: SOF: ipc4-pcm: Workaround for crashed firmware on system suspend
by Sasha Levin 29 Feb '24

From: Peter Ujfalusi <peter.ujfalusi(a)linux.intel.com> [ Upstream commit c40aad7c81e5fba34b70123ed7ce3397fa62a4d2 ] When the system is suspended while audio is active, the sof_ipc4_pcm_hw_free() is invoked to reset the pipelines since during suspend the DSP is turned off, streams will be re-started after resume. If the firmware crashes during while audio is running (or when we reset the stream before suspend) then the sof_ipc4_set_multi_pipeline_state() will fail with IPC error and the state change is interrupted. This will cause misalignment between the kernel and firmware state on next DSP boot resulting errors returned by firmware for IPC messages, eventually failing the audio resume. On stream close the errors are ignored so the kernel state will be corrected on the next DSP boot, so the second boot after the DSP panic. If sof_ipc4_trigger_pipelines() is called from sof_ipc4_pcm_hw_free() then state parameter is SOF_IPC4_PIPE_RESET and only in this case. Treat a forced pipeline reset similarly to how we treat a pcm_free by ignoring error on state sending to allow the kernel's state to be consistent with the state the firmware will have after the next boot.

Of course the definitions should be put in a "common header" for that to actually work in your described situation, but it's not a big deal. Mine wasn't a strong opinion: that does actually matter in case you expect more quirks (or something that is not a quirk, but a functional flag instead) to eventually get there... but otherwise, it's actually the same. It's your choice in the end, I'm fine with both anyway :-) Cheers, Angelo

[PATCH] ASoC: SOF: amd: fix soundwire dependencies
by Arnd Bergmann 21 Feb '24

21 Feb '24

From: Arnd Bergmann <arnd(a)arndb.de> The soundwire-amd driver has a bit of a layering violation requiring the SOF driver to directly call into its exported symbols rather than through an abstraction. The SND_SOC_SOF_AMD_SOUNDWIRE Kconfig symbol tries to deal with the dependency by selecting SOUNDWIRE_AMD in a complicated set of conditions, but gets it wrong for a configuration involving SND_SOC_SOF_AMD_COMMON=y, SND_SOC_SOF_AMD_ACP63=m, and SND_SOC_SOF_AMD_SOUNDWIRE_LINK_BASELINE=m SOUNDWIRE_AMD=m, which results in a link failure: ld.lld: error: undefined symbol: sdw_amd_get_slave_info >>> referenced by acp-common.c ld.lld: error: undefined symbol: amd_sdw_scan_controller ld.lld: error: undefined symbol: sdw_amd_probe ld.lld: error: undefined symbol: sdw_amd_exit >>> referenced by acp.c >>> sound/soc/sof/amd/acp.o:(amd_sof_acp_remove) in archive vmlinux.a In essence, the SND_SOC_SOF_AMD_COMMON option cannot be built-in when trying to link against a modular SOUNDWIRE_AMD driver. Since CONFIG_SOUNDWIRE_AMD is a user-visible option, it really should never be selected by another driver in the first place, so replace the extra complexity with a normal Kconfig dependency in SND_SOC_SOF_AMD_SOUNDWIRE, plus a top-level check that forbids any of the AMD SOF drivers from being built-in with CONFIG_SOUNDWIRE_AMD=m. In normal configs, they should all either be built-in or all loadable modules anyway, so this simplification does not limit any real usecases.

[1/1] ASoC: SOF: amd: Fix locking in ACP IRQ handler commit: c4b603c6e2df3a17831731d8bbec5c16fa7bbdf8 All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark
