[alsa-devel] [PATCH] ASoC: Intel: Show Baytrail SST DSP firmware details during init
DSP initialization complete message IPC_IA_FW_INIT_CMPLT is a large message carrying firmware details in mailbox. Read and show those details during init in order to be able to get that information to QA reports.

Applied, thanks. Is it worth putting these into sysfs file so we can get the data read out with alsa-info.sh?

Not a bad idea. I'm not going to be implementing it instantly but should such a file be one generic node listing all the sound components that use fw and their info or a node with fixed name under each device's directory? Latter one sounds a bit simpler in kernel but I'm thinking which way makes most sense for utilities.
