GOP linear frame buffer
Posted: Tue Dec 23, 2014 11:49 am
Howdy,
So I was attempting to get the GOP information (mainly the linear frame buffer address) in my
bootstrap, but I can't seem to find any examples of that.
For GRUB2 on conventional old BIOS, I was able to just move the VBE info into a structure defined in my kernel.c,
and I was able to do this in the boot.s
Can the GOP information be retrieved in the boot.s for UEFI GRUB2 or do I need to build a UEFI
application from the ground up using one of the UEFI tool kits?
