Subject: [PATCH v10 00/13] iommu: Shared Virtual Addressing for SMMUv3 (PT sharing part)
Date: Fri, 18 Sep 2020 12:18:40 +0200 [thread overview]
Message-ID: <20200918101852.582559-1-jean-philippe@linaro.org> (raw)
This is version 10 of the page table sharing support for Arm SMMUv3.
Patch 1 still needs an Ack from mm maintainers. However patches 4-11 do
not depend on it, and could get merged for v5.10 regardless.
v10:
* Fix patches 3, 8, 9 and 10 following Eric's review.
v9 resend: https://lore.kernel.org/linux-iommu/20200817171558.325917-1-jean-philippe@linaro.org/
* Rebased onto v5.9-rc1. Moved to drivers/iommu/arm/arm-smmu-v3/ as a
result.
v9: https://lore.kernel.org/linux-iommu/20200723145724.3014766-1-jean-philippe@linaro.org/
* Moved most of the SVA code to arm-smmu-v3-sva.c. 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 a bug when replacing a private ASID.
v8: https://lore.kernel.org/linux-iommu/20200618155125.1548969-1-jean-philippe@linaro.org/
* Split SVA series into three parts: page table sharing, I/O page
faults, and additional features (DVM, VHE and HTTU).
Fenghua Yu (1):
mm: Define pasid in mm
Jean-Philippe Brucker (12):
iommu/ioasid: Add ioasid references
iommu/sva: Add PASID helpers
arm64: mm: Pin down ASIDs for sharing mm with devices
iommu/io-pgtable-arm: Move some definitions to a header
arm64: cpufeature: Export symbol read_sanitised_ftr_reg()
iommu/arm-smmu-v3: Move definitions to a header
iommu/arm-smmu-v3: Share process page tables
iommu/arm-smmu-v3: Seize private ASID
iommu/arm-smmu-v3: Check for SVA features
iommu/arm-smmu-v3: Add SVA device feature
iommu/arm-smmu-v3: Implement iommu_sva_bind/unbind()
iommu/arm-smmu-v3: Hook up ATC invalidation to mm ops
