[Qemu-devel] [PATCH v2 4/4] pc: set the OEM fields in the RSDT and the FADT from the SLIC |
Date: |
Mon, 18 Jan 2016 15:12:13 +0100 |
The Microsoft spec about the SLIC and MSDM ACPI tables at
<http://go.microsoft.com/fwlink/p/?LinkId=234834> requires the OEM ID and
OEM Table ID fields to be consistent between the SLIC and the RSDT/XSDT.
That further affects the FADT, because a similar match between the FADT
and the RSDT/XSDT is required by the ACPI spec in general.
This patch wires up the previous three patches.

Notes:
v2:
- rebase to new acpi_get_slic_oem() [MST]
- drop machine type property to disable this behavior [MST]
