[PULL 10/23] avocado_qemu: Add SMMUv3 tests |
Date: |

From: Eric Auger <eric.auger@redhat.com>
Add new tests checking the good behavior of the SMMUv3 protecting
2 virtio pci devices (block and net). We check the guest boots and
we are able to install a package. Different guest configs are tested:
standard, passthrough an strict=0. This is tested with both fedora 31 and
33. The former uses a 5.3 kernel without range invalidation whereas the
latter uses a 5.8 kernel that features range invalidation.
