[Qemu-devel] [PATCH v5 4/4] vfio: Enable vfio-pci and mark supported |
Date: |

User-agent: |
StGIT/0.14.3 |
Enabled for all softmmu guests supporting PCI on Linux hosts. Note
that currently only x86 hosts have the kernel side VFIO IOMMU support
for this. PPC (g3beige) is the only non-x86 guest known to work.
ARM (veratile) hangs in firmware, others untested.
