From 66a4020c3c2163aeffc9757851f33c346ecfd870 Mon Sep 17 00:00:00 2001

Subject: [PATCH] OvmfPkg: Enable BGRT in OVMF
By default, firmware (OVMF - Open source Virtual Machine Firmware)
never publishes BGRT (Boot Graphics Resource Table) and in the boot
process Linux kernel checks for this table and if it fails to find BGRT
table then corresponding code in Linux kernel is not executed. EDK II
(EFI Development Kit, thus OVMF) already has BGRT source code packaged
into it but it is excluded from the build process of OVMF. These changes
to build system of OVMF enables BGRT in 32-bit and 64-bit OVMF.
There are only two files that need to be modified in order to do this.
The first one being OvmfPkg*.dsc (this file describes the platform) and
the second one being OvmfPkg*.fdf (this file describes firmware descriptor
volume). A *.inf file (here "BootGraphicsResourceTableDxe.inf")
describes a module (here BGRT). So, include
"BootGraphicsResourceTableDxe.inf" file in "OvmfPkg*.dsc" so that BGRT
source code will be compiled and "BootGraphicsResourceTableDxe.efi" file
is generated and we should also include
"BootGraphicsResourceTableDxe.inf" file in "OvmfPkg*.fdf" file so that
"BootGraphicsResourceTableDxe.efi" will be placed in a firmware volume
and thus gets published.
