See http://www.infradead.org/rpr.html Sender: linux-kernel-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Hi Robin and Joerg, I think we are finally ready for the generic dma-iommu series. I have various DMA API changes pending, and Tom has patches ready to convert the AMD and Intel iommu drivers over to it. I'd love to have this in a stable branch shared between the dma-mapping and iommu trees the day after rc2 is released. I volunteer to create the branch, but I'm fine with it living in the iommu tree as well. A git tree is also available at: git://git.infradead.org/users/hch/misc.git dma-iommu-ops.6 Gitweb: http://git.infradead.org/users/hch/misc.git/shortlog/refs/heads/dma-iommu-ops.6 Changes since v5: - rebased to latest linus tree and dropped a patch now merged - remove the now pointless __dma_iommu_mmap function - restore a cleanup from Robin that would have caused a conflict in last merge winow, but is fine now Changes since v4: - rebased to 5.2-rc1 Changes since v3: - fold the separate patch to refactor mmap bounds checking - don't warn on not finding a vm_area - improve a commit log - refactor __dma_iommu_free a little differently - remove a minor MSI map cleanup to avoid a conflict with the "Split iommu_dma_map_msi_msg" series Changes since v2: - address various review comments and include patches from Robin Changes since v1: - only include other headers in dma-iommu.h if CONFIG_DMA_IOMMU is enabled - keep using a scatterlist in iommu_dma_alloc - split out mmap/sgtable fixes and move them early in the series - updated a few commit logs _______________________________________________ iommu mailing list iommu@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/iommu
