Subject: [PATCH 1/1] Add BGRT ACPI table inclusion support in OVMF
Date: Mon, 26 Dec 2016 10:55:35 +0530	[thread overview]
Message-ID: <1482729935-25823-1-git-send-email-bhsharma@redhat.com> (raw)

During debugging Linux kernel for ACPI BGRT support
(especially on VMs), it is sometimes very useful to have
the EFI firmware (OVMF in most cases which use Tianocore)
to export the ACPI BGRT table.

This patch tries to add this support.

I have tested this patch on a RHEL7.3 and Fedora-25 KVM
and ensured that the BGRT logo is properly prepared and
can be viewed with user-space tools (like 'Gwenview' on KDE,
for example):

$ file /sys/firmware/acpi/bgrt/image
/sys/firmware/acpi/bgrt/image: PC bitmap, Windows 3.x format, 193 x 58 x
24
