Hello François,

Thanks for sharing.

Which organization do you refer to by ad-hoc forum? Ad-hoc does not sound
like a specification body. Wouldn't this work be done in the UEFI Forum?

If ACPI looses the dynamic powers of ASL, what purpose would it serve that
is not already covered by device-trees?

Do the Mercedes aficionados plan to upstream the drivers changes?

Best regards

Heinrich
