[PATCH 0/2] Additional vIOMMU fixes related to UNMAP notifiers

Posted by Eric Auger 3 years, 2 months ago

958ec334bca3 ("vhost: Unbreak SMMU and virtio-iommu on dev-iotlb
support") fixed part of the UNMAP related regressions introduced by
b68ba1ca5767 ("memory: Add IOMMU_NOTIFIER_DEVIOTLB_UNMAP
IOMMUTLBNotificationType").

However the case of the spapr_iommu was not addressed. It should be
identical to the others. Also 958ec334bca3 introduced a regresion
on the VIRTIO-IOMMU/VFIO integration.

spapr_iommu is not tested.

Best Regards

Eric
