Subject: [PATCH v9 00/13] iommu: Shared Virtual Addressing for SMMUv3 (PT sharing part)
Date: Thu, 23 Jul 2020 16:57:12 +0200 [thread overview]
Message-ID: <20200723145724.3014766-1-jean-philippe@linaro.org> (raw)
Add support for sharing CPU page tables with the SMMUv3. Support for I/O
page faults and additional features (DVM, VHE and HTTU) needed for SVA
is available on my sva/current branch [2] and will be sent later.
Since v8 [1]:
* Moved the SVA code to arm-smmu-v3-sva.c under CONFIG_ARM_SMMU_V3_SVA.
This required moving struct definitions and macros to arm-smmu-v3.h
(patch 7), hence the new 700 insertions/deletions in the diffstat.
* Updated patches 4 and 8 following review.
* Fixed bug in patch 9 when replacing a private ASID.
