This patch replaces ARM-specific IOMMU-based DMA-mapping implementation with generic IOMMU DMA-mapping code shared with ARM64 architecture. The side-effect of this change is a switch from bitmap-based IO address space management to tree-based code. There should be no functional changes for drivers, which rely on initialization from generic arch_setup_dna_ops() interface. Code, which used old arm_iommu_* functions must be updated to new interface. Signed-off-by: Marek Szyprowski<m.szyprowski@xxxxxxxxxxx>
IOMMU works good on drm/rockchip ARM64 platform with this patch. So Tested-by: Mark Yao <mark.yao@xxxxxxxxxxxxxx> Thanks. -- Ｍark Yao _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
