My topics:

I'll add these to the agenda.

- SOF driver: ACPI / DT unification

Are there concrete plans to discuss here or is this more of a
"what are we doing" kind of thing?  ACPI standardization has been
an issue :/

I took this agenda item as "how machine drivers are handled in SOF".

Currently the core creates a platform device which will result in a machine driver being probe and the card created. This is mainly due to the lack of 'machine device' in existing DSDT tables. DT has explicit support for machine drivers, so we need to have a solution that caters to both.


- SOF driver: Handling built-in driver use case

What's the issue here?

The SOF driver (or any existing driver with closed-source firmware) will not work when compiled as built-in due to the request_firmware() dependency. This wasn't too much of an issue for Intel so far, but for i.MX platforms it's quite common to have no modules.

Daniel, did I get things right?
