[PATCH v2 05/19] util/vfio-helpers: Improve reporting unsupported IOMMU type |
Date: |
Mon, 26 Oct 2020 11:54:50 +0100 |
Change the confuse "VFIO IOMMU check failed" error message by
the explicit "VFIO IOMMU Type1 is not supported" once.
Example on POWER:
$ qemu-system-ppc64 -drive
if=none,id=nvme0,file=nvme://0001:01:00.0/1,format=raw
qemu-system-ppc64: -drive
if=none,id=nvme0,file=nvme://0001:01:00.0/1,format=raw: VFIO IOMMU Type1 is not
supported
