From 1834c081d3db78df045f7e243e8bb169c4a12e2e Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Wed, 3 Nov 2021 21:09:10 -0600 Subject: efi: Add video support to the app The current EFI video driver only works when running in the stub. In that case the stub calls boot services (before jumping to U-Boot proper) and copies the graphics info over to the efi table. This is necessary because the stub exits boot services before jumping to U-Boot. The app maintains access to boot services throughout its life, so does not need to do this. Update the driver to support calling boot services directly. Enable video output for the app. Note that this uses the EFI_GRAPHICS_OUTPUT_PROTOCOL protocol, even though it mentions vesa. A sample qemu command-line for this case is: qemu-system-x86_64 -bios /usr/share/edk2.git/ovmf-ia32/OVMF-pure-efi.fd -drive id=disk,file=try.img,if=none,format=raw -nic none -device ahci,id=ahci -device ide-hd,drive=disk,bus=ahci.0 Signed-off-by: Simon Glass Reviewed-by: Heinrich Schuchardt --- arch/x86/dts/efi-x86_app.dts | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'arch') diff --git a/arch/x86/dts/efi-x86_app.dts b/arch/x86/dts/efi-x86_app.dts index 04e044a07a8..a5316e2a1a7 100644 --- a/arch/x86/dts/efi-x86_app.dts +++ b/arch/x86/dts/efi-x86_app.dts @@ -25,4 +25,8 @@ compatible = "efi,reset"; u-boot,dm-pre-reloc; }; + efi-fb { + compatible = "efi-fb"; + }; + }; -- cgit v1.2.3
