Hi, This series adds a dma_dir field to the vb2_queue structure in order to store the DMA direction once for all in vb2_queue_init(); It also adds a new capture_dma_bidirectional flag to the vb2_queue structure allowing the hardware to read from the CAPTURE buffer. This flag is ignored for OUTPUT queues. This is used on ChromeOS by the rockchip-vpu driver. Changes since v1: - Renamed use_dma_bidirectional field as capture_dma_bidirectional - Added a VB2_DMA_DIR() macro Pawel Osciak (2): [media] vb2: Store dma_dir in vb2_queue [media] vb2: Add support for capture_dma_bidirectional queue flag drivers/media/v4l2-core/videobuf2-core.c | 12 +++--------- drivers/media/v4l2-core/videobuf2-v4l2.c | 6 ++++++ include/media/videobuf2-core.h | 6 ++++++ 3 files changed, 15 insertions(+), 9 deletions(-) -- 2.7.4 -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
