Re: [Xen-devel] [PATCH 0/7] SMMUv3 driver



Hi,

This patch set adds support for the SMMUv3 driver. This is a continuation on
a RFCv4.[1]
The IORT support came from [2]. This RFC has some conflicting defines that
have to be addressed by introducing the linux_compat.h header in IORT patch
set. In any case the SMMU changes apply on top of IORT patches.

The SMMUv3 series looks in good state and I would like to see this merged for Xen 4.11. Manish, do we have an update on the IORT side?

Cheers,


List of changes:
- Addition of a linux_compat header.
- Addition of a common header for arm smmu defines.
- Rebase of the SMMUv3 driver to the driver in linux kernel 4.14 rc7.
- New config defines for ARM SMMU drivers.
