The OpRegion shouldn''t be mapped 1:1 because the address in the host can''t be used in the guest directly. This patch traps read and write access to the opregion of the Intel GPU config space (offset 0xfc). To work correctly this patch needs a change in hvmloader. HVMloader will allocate 2 pages for the OpRegion and write this address on the config space of the Intel GPU. Qemu
