[Qemu-devel] [PATCH fixup 0/2] Vhost device IOTLB fixup for vfio enablment

Posted by Jason Wang 7 years, 1 month ago

Hi:

This series is a fixup for vfio enablement series which breaks vhost
device IOTLB. The main reason is that vhost device IOTLB assumes the
iommu region were alwasy as->root. Fixing by using a memory listener
to register iommu notifiers.

Please review.

  intel_iommu: use the correct memory region for device IOTLB
    notification
  vhost: genearlize iommu memory region
