+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.
