Subject: [PATCH RESEND v9 00/13] iommu: Shared Virtual Addressing for SMMUv3 (PT sharing part)
Date: Mon, 17 Aug 2020 19:15:46 +0200	[thread overview]
Message-ID: <20200817171558.325917-1-jean-philippe@linaro.org> (raw)

This is version 9 of the page table sharing support for SMMUv3, rebased
onto v5.9-rc1.

v9 resend:
* 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
