Update BIOS INT15-E820 to allow a larger BIOS image
The bios will now reserve more memory via the E820 functions. Note that the standard KVM BIOS will most likely not make use of this expanded BIOS region. This change will synchronize the BIOS INT15-E820 reservations to match other changes that will allow alternate BIOS images to be larger in size. Previously the BIOS reserved: 0xfffbc000-0xfffbcfff - 4KB - EPT identity mapping pages 0xfffbd000-0xfffbffff - 12KB - TSS pages 0xfffc0000-0xffffffff - 256KB - Max bios.bin (usually top 128KB is used) Now the BIOS will reserve: 0xfeffc000-0xfeffcfff - 4KB - EPT identity mapping pages 0xfeffd000-0xfeffffff - 12KB - TSS Pages 0xff000000-0xffffffff - 16MB - Max bios.bin Signed-off-by: Jordan Justen <> Signed-off-by: Avi Kivity <>
