2025-12-10ALSA: hda: intel-dsp-config: Prefer legacy driver as fallbackTakashi Iwai
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.

Check in snd_intel_dsp_check_soundwire() that the pointer returned by ACPI_HANDLE() is not NULL, before passing it on to other functions.

2025-08-28ALSA: hda: Avoid binding with SOF for SKL/KBL platformsTakashi Iwai
For Intel SKL and KBL platforms, it may be bound with one of three HD-audio drivers (AVS, SOF and legacy). AVS is the preferred one when DMIC is detected, and that's how it's defined in the snd-intel-dspcfg config table. But, when AVS driver is disabled (CONFIG_SND_SOC_INTEL_AVS=n), the device may be bound freely with either SOF or legacy driver. Before 6.17, the legacy driver took it primarily, but on 6.17, likely due to the recent code shuffling, SOF driver seems taking it at first, and fails to probe. For avoiding the regression, we should enforce to bind those with the legacy HD-audio drvier when AVS is disabled. This patch adds the extra two entries in intel-dspcfg table that are applied only when CONFIG_SND_SOC_INTEL_AVS=n, for binding with the legacy driver. Note that there are entries for APL in that config table block, but APL may be supported by SOF for certain setups, so the choice can't be exclusive. Hence this patch includes only SKL and KBL.
