I think Ben has reached out to me earli= er about something like this but I haven=E2=80=99t had a chance to implemen= t... Sorry about the delay.. How soon is the iASL/ACPICA support needed for= CDAT and CDET? CDAT and CEDT definitions in include/acpi/actbl* would be useful as soon as v5.12. If that's too soon I don't think we're blocked, but the driver is fast approaching the point where it needs to consult these tables to enable higher order functionality.
