[Xen-devel] [PATCH 1/2] graphics passthrough with VT-d |
This patch supports basic gfx passthrough on xen side:
- retrieves VGA bios from host VGA BIOS address (0xC0000), then load it to
guest VGA BIOS address (This is the same with XCI).
- Enlarge guest MMIO range to contain gfx card's large memory
- add a config option 'gfx_passthru' for gfx passthrough
