Subject: [PATCH v9 0/6] paravirtual IOMMU pre-requisites and clean-up
Date: Thu, 13 Sep 2018 16:21:20 +0100	[thread overview]
Message-ID: <20180913152128.6114-1-paul.durrant@citrix.com> (raw)

This series contains pre-requisites and clean-up needed for paravirtual
IOMMU support.

I have separated these patches to avoid further delaying their application
whilst I re-work the implementation of paravirtual IOMMU after review of
v6 of the series. Several of them already have all necessary acks.

Paul Durrant (7):
  iommu: introduce the concept of DFN...
  iommu: make use of type-safe DFN and MFN in exported functions
  iommu: push use of type-safe DFN and MFN into iommu_ops
  iommu: don't domain_crash() inside iommu_map/unmap_page()
  memory: add check_get_page_from_gfn() as a wrapper...
  vtd: add missing check for shared EPT...
  vtd: add lookup_page method to iommu_ops
