Could you elaborate on what is upcoming here? Also, on a semi-related note, are there limitations on how many pages can be left mapped by the iommu? Some of the page pool work involves leaving the pages mapped instead of constantly mapping/unmapping them. On a heavily loaded box with iommu enabled, it seems that quite often there is contention on the iova_lock. Are there known issues in this area? -- Jonathan _______________________________________________ iommu mailing list iommu@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/iommu
