[media] vim2m: copy the other colorspace-related fields as well

2016-07-28T23:13:56Z

The xfer_func, ycbcr_enc and quantization fields should also be copied from output to capture format. Since this driver serves as example code it is important that this is handled correctly. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] vb2: replace void alloc_ctxs by struct device alloc_devs

2016-07-08T17:45:07Z

Make this a proper typed array. Drop the old allocate context code since that is no longer used. Note that the memops functions now get a struct device pointer instead of the struct device ** that was there initially (actually a void pointer to a struct containing only a struct device pointer). This code is now a lot cleaner. Signed-off-by: Hans Verkuil Reviewed-by: Laurent Pinchart Cc: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

[media] media: videobuf2: Move timestamp to vb2_buffer

2015-12-18T15:53:31Z

Move timestamp from struct vb2_v4l2_buffer to struct vb2_buffer for common use, and change its type to u64 in order to handling y2038 problem. This patch also includes all device drivers' changes related to this restructuring.

[media] vb2: drop v4l2_format argument from queue_setup

2015-12-18T15:48:19Z

The queue_setup callback has a void pointer that is just for V4L2 and is the pointer to the v4l2_format struct that was passed to VIDIOC_CREATE_BUFS. The idea was that drivers would use the information from that struct to buffers suitable for the requested format. After the vb2 split series this pointer is now a void pointer, which is ugly, and the reality is that all existing drivers will effectively just look at the sizeimage field of v4l2_format. To make this more generic the queue_setup callback is changed: the void pointer is dropped, instead if the *num_planes argument is 0, then use the current format size, if it is non-zero, then it contains the number of requested planes and the sizes array contains the requested sizes. If either is unsupported, then return -EINVAL, otherwise use the requested size(s). Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] media: videobuf2: Restructure vb2_buffer

2015-10-01T12:04:43Z

Remove v4l2 stuff - v4l2_buf, v4l2_plane - from struct vb2_buffer. Add new member variables - bytesused, length, offset, userptr, fd, data_offset - to struct vb2_plane in order to cover all information of v4l2_plane. struct vb2_plane { unsigned int bytesused; unsigned int length; union { unsigned int offset; unsigned long userptr; int fd; } m; unsigned int data_offset; } Replace v4l2_buf with new member variables - index, type, memory - which are common fields for buffer management. struct vb2_buffer { unsigned int index; unsigned int type; unsigned int memory; unsigned int num_planes; struct vb2_plane planes[VIDEO_MAX_PLANES]; }; v4l2 specific fields - flags, field, timestamp, timecode, sequence - are moved to vb2_v4l2_buffer in videobuf2-v4l2.c struct vb2_v4l2_buffer { struct vb2_buffer vb2_buf; __u32 flags; __u32 field; struct timeval timestamp; struct v4l2_timecode timecode; __u32 sequence; }; Signed-off-by: Junghak Sung Signed-off-by: Geunyoung Kim Acked-by: Seung-Woo Kim Acked-by: Inki Dae Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
