Hi all, this series adds the new noncontiguous DMA allocation API requested by various media driver maintainers.
Changes since v2: - rebased to Linux 5.12-rc1 - dropped one already merged patch - pass an attrs argument to dma_alloc_noncontigous - clarify the dma_vmap_noncontiguous documentation a bit - fix double assignments in uvcvideo Changes since v1: - document that flush_kernel_vmap_range and invalidate_kernel_vmap_range must be called once an allocation is mapped into KVA - add dma-debug support - remove the separate dma_handle argument, and instead create fully formed DMA mapped scatterlists - use a directional allocation in uvcvideo - call invalidate_kernel_vmap_range from uvcvideo _______________________________________________ iommu mailing list iommu@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/iommu
