Merge tag 'iommu-updates-v5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu

2021-05-01T16:33:00Z

Pull iommu updates from Joerg Roedel: - Big cleanup of almost unsused parts of the IOMMU API by Christoph Hellwig. This mostly affects the Freescale PAMU driver. - New IOMMU driver for Unisoc SOCs - ARM SMMU Updates from Will: - Drop vestigial PREFETCH_ADDR support (SMMUv3) - Elide TLB sync logic for empty gather (SMMUv3) - Fix "Service Failure Mode" handling (SMMUv3) - New Qualcomm compatible string (SMMUv2) - Removal of the AMD IOMMU performance counter writeable check on AMD. It caused long boot delays on some machines and is only needed to work around an errata on some older (possibly pre-production) chips. If someone is still hit by this hardware issue anyway the performance counters will just return 0. - Support for targeted invalidations in the AMD IOMMU driver. Before that the driver only invalidated a single 4k page or the whole IO/TLB for an address space. This has been extended now and is mostly useful for emulated AMD IOMMUs. - Several fixes for the Shared Virtual Memory support in the Intel VT-d driver - Mediatek drivers can now be built as modules - Re-introduction of the forcedac boot option which got lost when converting the Intel VT-d driver to the common dma-iommu implementation. - Extension of the IOMMU device registration interface and support iommu_ops to be const again when drivers are built as modules. * tag 'iommu-updates-v5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (84 commits) iommu: Streamline registration interface iommu: Statically set module owner iommu/mediatek-v1: Add error handle for mtk_iommu_probe iommu/mediatek-v1: Avoid build fail when build as module iommu/mediatek: Always enable the clk on resume iommu/fsl-pamu: Fix uninitialized variable warning iommu/vt-d: Force to flush iotlb before creating superpage iommu/amd: Put newline after closing bracket in warning iommu/vt-d: Fix an error handling path in 'intel_prepare_irq_remapping()' iommu/vt-d: Fix build error of pasid_enable_wpe() with !X86 iommu/amd: Remove performance counter pre-initialization test Revert "iommu/amd: Fix performance counter initialization" iommu/amd: Remove duplicate check of devid iommu/exynos: Remove unneeded local variable initialization iommu/amd: Page-specific invalidations for more than one page iommu/arm-smmu-v3: Remove the unused fields for PREFETCH_CONFIG command iommu/vt-d: Avoid unnecessary cache flush in pasid entry teardown iommu/vt-d: Invalidate PASID cache when root/context entry changed iommu/vt-d: Remove WO permissions on second-level paging entries iommu/vt-d: Report the right page fault address ...

uacce: Enable IOMMU_DEV_FEAT_IOPF

2021-04-07T08:54:29Z

The IOPF (I/O Page Fault) feature is now enabled independently from the SVA feature, because some IOPF implementations are device-specific and do not require IOMMU support for PCIe PRI or Arm SMMU stall. Enable IOPF unconditionally when enabling SVA for now. In the future, if a device driver implementing a uacce interface doesn't need IOPF support, it will need to tell the uacce module, for example with a new flag.

drm, iommu: Change type of pasid to u32

2020-09-17T17:21:16Z

PASID is defined as a few different types in iommu including "int", "u32", and "unsigned int". To be consistent and to match with uapi definitions, define PASID and its variations (e.g. max PASID) as "u32". "u32" is also shorter and a little more explicit than "unsigned int". No PASID type change in uapi although it defines PASID as __u64 in some places.
