Ok, glad you got that working. What about the ACPI changes? I see that these are needed to get a clean build, and as I understood it, they are supposed to get merged through the acpica tree. > This branch can be built with defconfig and allmodconfig (except > drivers/platform/surface/aggregator/controller.c, because it requires > 8bit/16bit cmpxchg, which I was told to remove their support). Right, that is ok to keep in there, we should fix that by adding a Kconfig dependency for the driver. It looks like it has a CONFIG_ACPI dependency, so it is currently limited to x86/arm64/ia64, which all have the short cmpxchg(), but in reality this driver can only work on x86 and arm64. Arnd
