[RFCv3 PATCH 01/10] videobuf2-core.h: improve documentation

From: Hans Verkuil Document that drivers can access/modify the buffer contents in buf_prepare and buf_finish. That was not clearly stated before. Signed-off-by: Hans Verkuil --- include/media/videobuf2-core.h | 32 +--- 1 file changed, 17 insertions(+), 15 deletions

[RFCv3 PATCH 00/10] vb2: improve dma-sg, expbuf

Changes since v2: - Dropped buf_prepare/finish_for_cpu: buf_prepare/finish are already suitable for CPU access (but see discussion on dmabuf imports below) - Moved dma_map_sg to buf_init as suggested by Laurent and others. This made it possible to drop the whole 'new_cookies' handling that I h

[RFCv3 PATCH 08/10] vb2: replace 'write' by 'dma_dir'

From: Hans Verkuil The 'write' argument is very ambiguous. I first assumed that if it is 1, then we're doing video output but instead it meant the reverse. Since it is used to setup the dma_dir value anyway it is now replaced by the correct dma_dir value which is unambiguous. Signed-off-by: Han

[RFCv3 PATCH 04/10] vb2-dma-sg: move dma_(un)map_sg here

From: Hans Verkuil This moves dma_(un)map_sg to the get_userptr/put_userptr and alloc/put memops of videobuf2-dma-sg.c and adds dma_sync_sg_for_device/cpu to the prepare/finish memops. Now that vb2-dma-sg will sync the buffers for you in the prepare/finish memops we can drop that from the driver

[RFCv3 PATCH 02/10] vb2-dma-contig: sync mem for cpu after mapping

From: Hans Verkuil The driver might touch the data after mapping in buf_prepare, so make sure it is synced for cpu. Signed-off-by: Hans Verkuil --- drivers/media/v4l2-core/videobuf2-dma-contig.c | 6 ++ 1 file changed, 6 insertions(+) diff --git a/drivers/media/v4l2-core/videobuf2-dma-con

[RFCv3 PATCH 07/10] vb2-vmalloc: add get_dmabuf support

From: Hans Verkuil Add support for DMABUF exporting to the vb2-vmalloc implementation. All memory models now have support for both importing and exporting of DMABUFs. Signed-off-by: Hans Verkuil --- drivers/media/v4l2-core/videobuf2-vmalloc.c | 174 1 file changed

[RFCv3 PATCH 03/10] vb2-dma-sg: add allocation context to dma-sg

[PATCH 00/12] dmaengine: remove users of device_control

The recent discussion [1] on the API have resulted in moving away from device_control ioctl method to proper channel APIs. There are still few users on the device_control which should use the wrappers existing rather than access device_control. This will aid us in deprecating and removing device_co
