Hi all, These two patches are to fix issues we encountered when using amdgpu on PVH dom0 with Xen hypervisor. Patch 1 is to fix a address problem that PVH type domain does a second address translation for pcidev, then causes the address to be not physical address, so we need to set amdgpu to be passthrough mode. Patch 2 is because PVH type domain uses VPCI of Xen, but VPCI doesn't support Resizable Bar capability, so just return success when discrete GPU tries to resize bars.
