git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu 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 ...

Amdgpu driver uses 4-byte data type as DQM fence memory, and transmits GPU address of fence memory to microcode through query status PM4 message.

Fence memory only allocates 4 bytes of memory, but microcode does write 8 bytes of memory, so there is a memory corruption.

Now that they are combined together, we can directly call the functions that we need and avoid this unnecessary duplication and complexity.

The acpi_get_table() should be coupled with acpi_put_table() if the mapped table is not used at runtime to release the table mapping which can prevent the memory leak. In kfd_create_crat_image_acpi(), crat_table is copied to pcrat_image, and in kfd_create_vcrat_image_cpu(), the acpi_table is only used to get the OEM information, so those two table mappings need to be released after using it.

2020-10-30drm/amdkfd: Fix getting unique_id in topologyKent Russell3-6/+1
Since the unique_id is now obtained in amdgpu in smu_late_init, topology misses getting the value during KFD device initialization. To work around this, we use amdgpu_amdkfd_get_unique_id to get the unique_id at read time. Due to this, we can remove unique_id from the kfd_dev structure, since we only need it in the KFD node properties struct Signed-off-by: Kent Russell <kent.russell@amd.com> Reviewed-by: Felix Kuehling <Felix.Kuehling@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
