Subject: [PATCH] vfio/ap: Don't initialize HOST_IOMMU_DEVICE with mdev
|
||
|
|
|
||
|
|
mdevs aren't "physical" devices and when asking for backing IOMMU info,
|
||
|
|
it fails the entire provisioning of the guest. Fix that by setting
|
||
|
|
vbasedev->mdev true so skipping HostIOMMUDevice initialization in the
|
||
|
|
presence of mdevs.
|
||
|
|
|
||
|
|
Fixes: 930589520128 ("vfio/iommufd: Implement HostIOMMUDeviceClass::realize() handler")
