[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v1 17/20] libacpi: Build DSDT for PVH guests
PVH guests require DSDT with only ACPI INFO (Xen-specific) and Processor
objects. We separate ASL's ACPI INFO definition into dsdt_acpi_info.asl so
that it can be included in ASLs for both HVM and PVH2.
