drm/exynos: consider DMA_NONE flag to dmabuf import 2013-01-25T05:38:44+00:00 Inki Dae inki.dae@samsung.com 2013-01-11T04:46:58+00:00 b8b5c139ba75cde517b3e5eb6e3e760c0824b238 This patch considers DMA_NONE flag for other drivers not using dma mapping framework with iommu such as 3d gpu driver or others. For example, there might be 3d gpu driver that has its own iommu hw unit and iommu table mapping mechnism. So in this case, the dmabuf buffer imported into this driver needs just only sg table to map the buffer with its own iommu table itself. So this patch makes dma_buf_map_attachment ignore dma_map_sg call and just return sg table containing pages if dma_data_direction is DMA_NONE.
