From b32487ca7b51ce430f15ec785269f11c25a6a560 Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Fri, 26 Apr 2024 10:38:58 -0500 Subject: [PATCH 1/5] ASoC: SOF: debug: Handle cases when fw_lib_prefix is not set, NULL The firmware libraries are not supported by IPC3, the fw_lib_path is not a valid parameter and it is always NULL. Do not create the debugfs file for IPC3 at all as it is not applicable. With IPC4 some vendors/platforms might not support loadable libraries and the fw_lib_prefix is left to NULL to indicate this. Handle such case with allocating "Not supported" string.

The users see a "No SoundWire machine driver found" message without any details, and the fallback to HDaudio w/ HDMI is used. We can reduce our support load with a clear dev_info() log that will give us a clear hint on the mismatch and why a machine driver/topology were not found. Example log on a MTL device: [ 13.158599] sof-audio-pci-intel-mtl 0000:00:1f.3: No SoundWire machine driver found for the ACPI-reported configuration: [ 13.158603] sof-audio-pci-intel-mtl 0000:00:1f.3: link 0 mfg_id 0x025d part_id 0x0713 version 0x3 [ 13.158606] sof-audio-pci-intel-mtl 0000:00:1f.3: link 1 mfg_id 0x025d part_id 0x1316 version 0x3 [ 13.158608] sof-audio-pci-intel-mtl 0000:00:1f.3: link 2 mfg_id 0x025d part_id 0x1316 version 0x3 In parallel, we will also provide an update to `alsa-info` to log all SoundWire peripherals found in ACPI tables.
