[Xen-devel] [PATCH v8 0/4] IOMMU support for ARM

[Julien Grall <julien.grall@xxxxxxxxxx>]

Hello,

This is the eight version of this patch series to add support for IOMMU on
ARM. It also adds driver to support ARM SMMU which is used for instance on
Midway.

Major changes see v7:
    - Rework patch #4 to handle correctly multiple grant mapping with
    the same MFN

For all changes see in each patch.

This series also depends on the interrupt reworking series [1]

A working tree can be found here:
    git://xenbits.xen.org/people/julieng/xen-unstable.git branch smmu-v8

Sincerely yours,
