Subject: [PATCH 0/2] Domain nesting info for arm-smmu
Date: Fri, 12 Feb 2021 16:28:57 +0530	[thread overview]
Message-ID: <20210212105859.8445-1-vivek.gautam@arm.com> (raw)

These couple of patches are adding nesting information for arm
and are based on the domain nesting info patches by Yi [1,2,3].

Based on the discussion in the thread [4], sending these out as
I have been using in my tree [5] for nested translation based
on virtio-iommu on Arm reference platforms.

Thanks & regards
Vivek
