[Xen-devel] [PATCH v5 00/14] IOMMU support for ARM

[Julien Grall <julien.grall@xxxxxxxxxx>]

Hello,

This is the fifth 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.

The ARM IOMMU architecture assumes that the page table is shared between the
processor and each IOMMU.

Major changes in v5:
    - A bunch of patch from the previous version has been pushed upstream
    - Drop protected-devices patch [1] as it's not needed
    - Add flush_tlb_domain helper
    - Rework "Clean cache PT ..." to only flush by small item

For all the other changes see in each patch.

This series also depends on the interrupt reworking serie [2].

A working tree can be found here:
    git://xenbits.xen.org/people/julieng/xen-unstable.git branch ssmu-v5

Sincerely yours,
