iommu: Add gfp parameter to iommu_alloc_resv_region

2022-10-21T08:49:32Z

Add gfp parameter to iommu_alloc_resv_region() for the callers to specify the memory allocation behavior. Thus iommu_alloc_resv_region() could also be available in critical contexts.

Pull iommu updates from Joerg Roedel: - remove the bus_set_iommu() interface which became unnecesary because of IOMMU per-device probing - make the dma-iommu.h header private - Intel VT-d changes from Lu Baolu: - Decouple PASID and PRI from SVA - Add ESRTPS & ESIRTPS capability check - Cleanups - Apple DART support for the M1 Pro/MAX SOCs - support for AMD IOMMUv2 page-tables for the DMA-API layer. The v2 page-tables are compatible with the x86 CPU page-tables. Using them for DMA-API prepares support for hardware-assisted IOMMU virtualization - support for MT6795 Helio X10 M4Us in the Mediatek IOMMU driver - some smaller fixes and cleanups * tag 'iommu-updates-v6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (59 commits) iommu/vt-d: Avoid unnecessary global DMA cache invalidation iommu/vt-d: Avoid unnecessary global IRTE cache invalidation iommu/vt-d: Rename cap_5lp_support to cap_fl5lp_support iommu/vt-d: Remove pasid_set_eafe() iommu/vt-d: Decouple PASID & PRI enabling from SVA iommu/vt-d: Remove unnecessary SVA data accesses in page fault path dt-bindings: iommu: arm,smmu-v3: Relax order of interrupt names iommu: dart: Support t6000 variant iommu/io-pgtable-dart: Add DART PTE support for t6000 iommu/io-pgtable: Add DART subpage protection support iommu/io-pgtable: Move Apple DART support to its own file iommu/mediatek: Add support for MT6795 Helio X10 M4Us iommu/mediatek: Introduce new flag TF_PORT_TO_ADDR_MT8173 dt-bindings: mediatek: Add bindings for MT6795 M4U iommu/iova: Fix module config properly iommu/amd: Fix sparse warning iommu/amd: Remove outdated comment iommu/amd: Free domain ID after domain_flush_pages iommu/amd: Free domain id in error path iommu/virtio: Fix compile error with viommu_capable() ...

arm64/sysreg: Standardise naming of ID_AA64MMFR0_EL1.ASIDBits

2022-09-09T09:59:02Z

For some reason we refer to ID_AA64MMFR0_EL1.ASIDBits as ASID. Add BITS into the name, bringing the naming into sync with DDI0487H.a. Due to the large amount of MixedCase in this register which isn't really consistent with either the kernel style or the majority of the architecture the use of upper case is preserved. No functional changes. Signed-off-by: Mark Brown Reviewed-by: Kristina Martsenko Link: https://lore.kernel.org/r/20220905225425.1871461-10-broonie@kernel.org Signed-off-by: Catalin Marinas

arm64/sysreg: Add _EL1 into ID_AA64MMFR0_EL1 definition names

2022-09-09T09:59:02Z

Normally we include the full register name in the defines for fields within registers but this has not been followed for ID registers. In preparation for automatic generation of defines add the _EL1s into the defines for ID_AA64MMFR0_EL1 to follow the convention. No functional changes.

iommu/arm-smmu-v3: Make default domain type of HiSilicon PTT device to identity

The DMA operations of HiSilicon PTT device can only work properly with identical mappings. So add a quirk for the device to force the domain as passthrough.
