Subject: [PATCH 0/3] vdpa: Check iova range on memory regions ops
Date: Tue,  5 Oct 2021 10:01:28 +0200	[thread overview]
Message-ID: <20211005080131.408506-1-eperezma@redhat.com> (raw)

At this moment vdpa will not send memory regions bigger than 1<<63.
However, actual iova range could be way more restrictive than that.

Since we can obtain the range through vdpa ioctl call, just save it
from the beginning of the operation and check against it.

Eugenio Pérez (3):
  vdpa: Skip protected ram IOMMU mappings
  vdpa: Add vhost_vdpa_section_end
  vdpa: Check for iova range at mappings changes
