Subject: [PATCH v3 00/14] iommu/amd: Add Generic IO Page Table Framework Support
Date: Sun, 4 Oct 2020 01:45:35 +0000 [thread overview]
Message-ID: <20201004014549.16065-1-suravee.suthikulpanit@amd.com> (raw)
The framework allows callable implementation of IO page table.
This allows AMD IOMMU driver to switch between different types
of AMD IOMMU page tables (e.g. v1 vs. v2).
This series refactors the current implementation of AMD IOMMU v1 page table
to adopt the framework. There should be no functional change.
Subsequent series will introduce support for the AMD IOMMU v2 page table.
Thanks,
Suravee
Change from V2 (https://lore.kernel.org/lkml/835c0d46-ed96-9fbe-856a-777dcffac967@amd.com/T/#t)
- Patch 2/14: Introduce helper function io_pgtable_cfg_to_data.
- Patch 13/14: Put back the struct iommu_flush_ops since patch v2 would run into
NULL pointer bug when calling free_io_pgtable_ops if not defined.
Change from V1 (https://lkml.org/lkml/2020/9/23/251)
- Do not specify struct io_pgtable_cfg.coherent_walk, since it is
not currently used. (per Robin)
- Remove unused struct iommu_flush_ops. (patch 2/13)
- Move amd_iommu_setup_io_pgtable_ops to iommu.c instead of io_pgtable.c
patch 13/13)
