[Qemu-devel] [PATCH v2 19/19] hw: i386: Implement the ACPI builder interface for PC |
Date: |
Mon, 29 Oct 2018 17:24:41 +0100 |
All PC machine type derivatives will use the same ACPI table build
methods. But with that change in place, any new x86 machine type will be
able to re-use the acpi-build API and customize part of it by defining
its own ACPI table build methods.
