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
