[PATCH 0/6] OvmfPkg/VirtioGpuDxe: map system memory addresses to device addresses

[Laszlo Ersek <lersek@redhat.com>]

Repo:   https://github.com/lersek/edk2.git
Branch: virtio_gpu_map

This series brings IOMMU support to VirtioGpuDxe. The interesting part
is patch#5.

I formatted the patches with function context, for easier review.

I regression-tested this series in various environments; IA32, X64,
AARCH64. My access to a SEV machine is still in the making, so I
couldn't test the patches on SEV.

Brijesh, if you could test the series for me on SEV, that would be
great. I also plan to test it on SEV, once my access is established.
