[SeaBIOS] [PATCH 1/4] add guest hint variable

This holds the hint whenever the guest is 32-bit or 64-bit, so seabios can optimize the memory layout (pci bar placement) accordingly. Default is '32' for best backward compatibility. Signed-off-by: Gerd Hoffmann --- src/fw/paravirt.h | 1 + src/fw/paravirt.c | 2 ++ 2 files changed, 3 insertio

[SeaBIOS] [PATCH 2/4] use guest hint as additional condition

check guest hint as additional condition to enable the 64-bit guest friendly memory layout. With '32' seabios will use traditional pci configuration for best compatibility: all PCI bars will be mapped into the 32-bit PCI MMIO window below 4G if they fit there. With '64' seabios will use the new p
