There's been two generations of dual GPU machines - ones that support runtime switching (whih I think is limited to the Z?) and ones that don't (the early SZs at least, probably all of them). The _DSM stuff we're interested in is for the runtime switching. > > Are the _DSM methods always attached to the > > nvidia device? > > As far as I can see the Z is the only one having it attached to the > nvidia device. In that case I think we're fine only worrying about that case. The interesting thing now is in whether this is Sony-specific or whether the same method is specified for other systems switching between the nvidia chipsets. -- Matthew Garrett | mjg59@xxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
