Currently various cache flush helpers are scattered around. This consolidates them by putting them in the existing iommu_flush structure. /* struct iommu_flush - Intel IOMMU cache invalidation ops * * @cc_inv: invalidate context cache * @iotlb_inv: Invalidate IOTLB and paging structure caches when software * has changed second-level tables. * @p_iotlb_inv: Invalidate IOTLB and paging structure caches when software * has changed first-level tables. * @pc_inv: invalidate pasid cache * @dev_tlb_inv: invalidate cached mappings used by requests-without-PASID * from the Device-TLB on a endpoint device. * @p_dev_tlb_inv: invalidate cached mappings used by requests-with-PASID * from the Device-TLB on an endpoint device */ struct iommu_flush { void (*cc_inv)(struct intel_iommu *iommu, u16 did, u16 sid, u8 fm, u64 type); void (*iotlb_inv)(struct intel_iommu *iommu, u16 did, u64 addr, unsigned int size_order, u64 type); void (*p_iotlb_inv)(struct intel_iommu *iommu, u16 did, u32 pasid, u64 addr, unsigned long npages, bool ih); void (*pc_inv)(struct intel_iommu *iommu, u16 did, u32 pasid, u64 granu); void (*dev_tlb_inv)(struct intel_iommu *iommu, u16 sid, u16 pfsid, u16 qdep, u64 addr, unsigned int mask); void (*p_dev_tlb_inv)(struct intel_iommu *iommu, u16 sid, u16 pfsid, u32 pasid, u16 qdep, u64 addr, unsigned long npages); }; The name of each cache flush ops is defined according to the spec section 6.5 so that people are easy to look up them in the spec.
