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

Hi Guys, ich_force_enable_hpet() in linux wants to do mmio. It calls ioremap_pte_range to map phys addr to a VA. Xen then updates the PV dom0''s L1 with requested io attributes. I''m trying to figure how to do this for PV in HVM container. I was hoping to update the EPT directly. I was thinking of just doing guest_physmap_add_entry() but the mfn is not going to be valid. Is there

Which branch/changeset are you using? I've heard that
