Web[PATCH v4 06/22] iommu/vt-d: add definitions for PFSID Jacob Pan Thu, 22 Mar 2024 20:10:44 -0700 When SRIOV VF device IOTLB is invalidated, we need to provide the PF source ID such that IOMMU hardware can gauge the depth of invalidation queue which is shared among VFs. In computing, an input–output memory management unit (IOMMU) is a memory management unit (MMU) connecting a direct-memory-access–capable (DMA-capable) I/O bus to the main memory. Like a traditional MMU, which translates CPU-visible virtual addresses to physical addresses, the … Meer weergeven The advantages of having an IOMMU, compared to direct physical addressing of the memory (DMA), include : • Large regions of memory can be allocated without the need to be contiguous … Meer weergeven The disadvantages of having an IOMMU, compared to direct physical addressing of the memory, include: • Some degradation of performance from translation … Meer weergeven • AMD has published a specification for IOMMU technology, called AMD-Vi. • IBM offered Extended Control Program Support: Virtual Storage Extended (ECPS:VSE) mode on its 43xx line; channel programs used virtual addresses.
