[Xen-devel] [PATCH v4 00/21] IOMMU support for ARM

[Julien Grall <julien.grall@xxxxxxxxxx>]

Hello

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

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

Major changes in v4:
    - Support upstream Linux DOM0 without any change (see patch #18)
    - Support 40bits address space in the SMMU drivers
    - Rebase on the latest Xen (some patches clashed with the hwdom series)

The patch series is divided following:
    - #1-#4: Small fixes on ARM code
    - #5: Fix grant-table with IOMMU. Will be necessary for ARM later
    - #6-#8: Small changes in amd and vtd IOMMU drivers
    - #10-#11: Add new device tree helpers
    - #12-#14: Prepare IOMMU code to add support for ARM
    - #15-#19: Add IOMMU architecture for ARM
    - #20: Add SMMU driver
    - #21: Add new bindings to notify Linux the device is protected by
    an IOMMU. This patch is not mandatory and just here for improvement.

This series also dependency on the interrupt series I've sent earlier
(see "xen/arm: Interrupt management reworking").

A working tree can be found here:
