Change arm_iommu_unmap_page to check the DMA attributes for buffer coherency support instead of checking the iommu page table. This change now requires that clients correctly set the DMA_ATTR_FORCE_COHERENT or DMA_ATTR_FORCE_NON_COHERENT DMA attributes in their unmap call if they used it with their map call. This will improve the performance of the arm_iommu_unmap_page call. Change-Id: Ie96ef0a1906a8732b7b1eef7bed8aa85abee95f4 Signed-off-by: Liam Mark <lmark@codeaurora.org> |
