From 6e5e544f227f031d0b45828b56cec5668dd1bf5b Mon Sep 17 00:00:00 2001 From: Bhupesh Sharma Date: Fri, 6 Jan 2017 15:17:15 +0530 Subject: OvmfPkg: Install BGRT ACPI table While debugging OS for ACPI BGRT support (especially on VMs), it is 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 in OvmfPkg. Tested this patch in the following environments: 1. On both RHEL7.3 and Fedora-25 VM guests running on a Fedora-24 Host: - 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 2. On a Windows-10 VM Guest running on a Fedora-24 Host: - Ensured that the BGRT ACPI table is properly prepared and can be read with freeware tool like FirmwareTablesView: ================================================== Signature : BGRT Firmware Provider : ACPI Length : 56 Revision : 1 Checksum : 129 OEM ID : INTEL OEM Table ID : EDK2 OEM Revision : 0x00000002 Creator ID : 0x20202020 Creator Revision : 0x01000013 Description : ================================================== Note from Laszlo Ersek : without the BGRT ACPI table, Windows 8 and Windows 10 first clear the screen, then display a blue, slanted Windows picture above the rotating white boot animation. With the BGRT ACPI table, Windows 8 and Windows 10 don't clear the screen, the blue Windows image is not displayed, and the rotating white boot animation is shown between the firmware's original TianoCore boot splash and (optional) "Start boot option" progress bar.
