Subject: [PATCH 0/7] Nvidia Arm SMMUv2 Implementation
Date: Thu, 29 Aug 2019 15:47:00 -0700 [thread overview]
Message-ID: <1567118827-26358-1-git-send-email-vdumpa@nvidia.com> (raw)
Hi All,
Nvidia Arm SMMUv2 implementation has two ARM SMMU(MMU-500) instances
that are used together for SMMU translations. The IOVA accesses from
HW devices are interleaved across these two SMMU instances and need
to be programmed identical except during tlb sync and fault handling.
This patch set adds Nvidia Arm SMMUv2 Implementation on top of ARM SMMU
driver to handle Nvidia specific implementation. It is also adding
hooks for tlb sync and fault handling to allow vendor specific
implementation for the same.
Please review the patch set and provide the feedback.
This patch set is based on the following branch as it is dependent on the
Arm SMMU Refactor changes from Robin Murphy that are present in this branch.
