[Qemu-devel] [PATCH 17/26] hw: i386: Convert PC machine type to firmware build methods |
Date: |
Mon, 22 Oct 2018 20:36:47 +0200 |
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.
