ALSA: hda: intel-dsp-config: Prefer legacy driver as fallback

2026-01-17T15:31:29+00:00

commit 161a0c617ab172bbcda7ce61803addeb2124dbff upstream. When config table entries don't match with the device to be probed, currently we fall back to SND_INTEL_DSP_DRIVER_ANY, which means to allow any drivers to bind with it. This was set so with the assumption (or hope) that all controller drivers should cover the devices generally, but in practice, this caused a problem as reported recently. Namely, when a specific kconfig for SOF isn't set for the modern Intel chips like Alderlake, a wrong driver (AVS) got probed and failed. This is because we have entries like: #if IS_ENABLED(CONFIG_SND_SOC_SOF_ALDERLAKE) /* Alder Lake / Raptor Lake */ { .flags = FLAG_SOF | FLAG_SOF_ONLY_IF_DMIC_OR_SOUNDWIRE, .device = PCI_DEVICE_ID_INTEL_HDA_ADL_S, }, .... #endif so this entry is effective only when CONFIG_SND_SOC_SOF_ALDERLAKE is set. If not set, there is no matching entry, hence it returns SND_INTEL_DSP_DRIVER_ANY as fallback. OTOH, if the kconfig is set, it explicitly falls back to SND_INTEL_DSP_DRIVER_LEGACY when no DMIC or SoundWire is found -- that was the working scenario. That being said, the current setup may be broken for modern Intel chips that are supposed to work with either SOF or legacy driver when the corresponding kconfig were missing. For addressing the problem above, this patch changes the fallback driver to the legacy driver, i.e. return SND_INTEL_DSP_DRIVER_LEGACY type as much as possible. When CONFIG_SND_HDA_INTEL is also disabled, the fallback is set to SND_INTEL_DSP_DRIVER_ANY type, just to be sure.

ALSA: core: fix up bus match const issues.

2025-06-19T13:31:33+00:00

[ Upstream commit 62f134ab190c5fd5c9f68fe638ad8e13bb8a4cb4 ] In commit d69d80484598 ("driver core: have match() callback in struct bus_type take a const *"), the match bus callback was changed to have the driver be a const pointer. Unfortunately that const attribute was thrown away when container_of() is called, which is not correct and was not caught by the compiler due to how container_of() is implemented. Fix this up by correctly preserving the const attribute of the driver passed to the bus match function which requires the hdac_driver match function to also take a const pointer for the driver structure.

Merge tag 'asoc-fix-v6.12-rc5' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus

2024-10-30T13:46:35+00:00

ASoC: Fixes for v6.12 The biggest set of changes here is Hans' fixes and quirks for various Baytrail based platforms with RT5640 CODECs, and there's one core fix for a missed length assignment for __counted_by() checking. Otherwise it's small device specific fixes, several of them in the DT bindings.

ASoC: Intel: sst: Support LPE0F28 ACPI HID

2024-10-25T13:10:11+00:00

Some old Bay Trail tablets which shipped with Android as factory OS have the SST/LPE audio engine described by an ACPI device with a HID (Hardware-ID) of LPE0F28 instead of 80860F28. Add support for this. Note this uses a new sst_res_info for just the LPE0F28 case because it has a different layout for the IO-mem ACPI resources then the 80860F28. An example of a tablet which needs this is the Vexia EDU ATLA 10 tablet, which has been distributed to schools in the Spanish Andalucía region.
