[Xen-devel] [PATCH 0/6] per-domain IOMMU control

[Paul Durrant <paul.durrant@citrix.com>]

This series is base on my recent 'use stashed domain create flags'
series [1] and Alexandru Isaila's 'Clean iommu_hap_pt_share enabled code'
patch [2]. It ultimately introduces a new 'passthrough' option to xl.cfg to
provide per-domain control over a guests IOMMU mappings.

Paul Durrant (6):
  domain: introduce XEN_DOMCTL_CDF_iommu
  use is_iommu_enabled() where appropriate...
  remove late (on-demand) construction of IOMMU page tables
  make passthrough/pci.c:deassign_device() static
  iommu: tidy up iommu_us_hap_pt() and need_iommu_pt_sync() macros
  introduce a 'passthrough' configuration option to xl.cfg...
