They might not be - Matthew's original question still stands. The old AMW0 was just a funny wrapper for direct BIOS calls - maybe we just need a different call here? What does Acer do - are they poking the EC directly, or is the call to AMW0 just different for these machines? > Could we just direct add those model to the blacklist in acer-wmi > driver? or we direct check dmi in acer-wmi for only support Acer > machines that were included AMW0 in DSDT? Interesting. If we can't autodetect whether it's a dummy interface or not, then, we should change acer-wmi to whitelist what it does support - Acer, Fujistu Siemens and Medion - rather than trying to blacklist every vendor that crops up. -Carlos -- To unsubscribe from this list: send the line "unsubscribe platform-driver-x86" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
