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.

WebThese allow VFIO iommu code to simplify its group attachment routine, by avoiding the extra IOMMU domain allocations and attach/detach sequences of the old code. Worths mentioning the exact match for enforce_cache_coherency is removed with this series, since there's very less value in doing that since KVM won't be able to take advantage of it -- …
WebUpdate the iommu_map() API to pass in the GFP argument, and fix all call sites. Replace iommu_map_atomic(). Audit the "enterprise" iommu drivers to make sure they do the right thing. Intel and S390 ignore the GFP argument and always use GFP_ATOMIC. This is problematic for iommufd anyhow, so fix it.
