Subject: [PATCH v4 0/6] Remove VT-d virtual command interface and IOASID
Date: Wed, 1 Mar 2023 15:56:40 -0800 [thread overview]
Message-ID: <20230301235646.2692846-1-jacob.jun.pan@linux.intel.com> (raw)

Hi all,
This patch set removes unused VT-d virtual command interface followed by
removal of the IOASID infrastructure.
This has only been tested on x86 platforms, need help with testing on ARM
SMMU and other architectures.
Thanks,
Jacob
ChangeLog:
v4:
- keep mm_pasid helpers inline as much as we can for fork performance
- separate GFP_ATOMIC to GFP_KERNEL change for bisectability
v3:
- moved helper functions for PASID under SVA code, avoided circular inclusion
between mm.h and iommu.h
- deleted makefiles
- put rename under a different patch
Jacob Pan (4):
iommu/vt-d: Remove virtual command interface
iommu/sva: Move PASID helpers to sva code
iommu/sva: Use GFP_KERNEL for pasid allocation
iommu/ioasid: Rename INVALID_IOASID
Jason Gunthorpe (2):
iommu/sva: Stop using ioasid_set for SVA
iommu: Remove ioasid infrastructure
