* [media] v4l: Add metadata buffer type and formatLaurent Pinchart2017-04-151-0/+1
| | | | | | | | | | | | | | | The metadata buffer type is used to transfer metadata between userspace and kernelspace through a V4L2 buffers queue. It comes with a new metadata capture capability and format description.

* [media] media: videobuf2: Move timestamp to vb2_bufferJunghak Sung2015-12-181-2/+2
| | | | | | | | | | | | | | 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] media: videobuf2: Prepare to divide videobuf2Junghak Sung2015-10-201-22/+6
| | | | | | | | | | | | | | | | | Prepare to divide videobuf2 - Separate vb2 trace events from v4l2 trace event. - Make wrapper functions that will move to v4l2-side. - Make vb2_core_* functions that will remain in core-side. - Add a callback function table for buffer operation which makes vb2-core to be able to invoke a v4l2-side functions. - Rename internal functions as vb2_*.

* [media] media: videobuf2: Restructure vb2_bufferJunghak Sung2015-10-011-17/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 { <snip> 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 { <snip> unsigned int index; unsigned int type; unsigned int memory; unsigned int num_planes; struct vb2_plane planes[VIDEO_MAX_PLANES]; <snip> }; 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 <jh1009.sung@samsung.com> Signed-off-by: Geunyoung Kim <nenggun.kim@samsung.com> Acked-by: Seung-Woo Kim <sw0312.kim@samsung.com> Acked-by: Inki Dae <inki.dae@samsung.com> Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
* [media] videobuf2: add trace eventsPhilipp Zabel2015-07-171-0/+97
| | | | | | | | | | | | | | | | Add videobuf2 specific vb2_qbuf and vb2_dqbuf trace events that mirror the v4l2_qbuf and v4l2_dqbuf trace events, only they include additional information about queue fill state and are emitted right before the buffer is enqueued in the driver or userspace is woken up. This allows to make sense of the timeline of trace events in combination with others that might be triggered by __enqueue_in_driver. Also two new trace events vb2_buf_queue and vb2_buf_done are added, allowing to trace the handover between videobuf2 framework and driver.

| | | | | | | | | | | | Trace events with exactly the same parameters and trace output, such as v4l2_qbuf and v4l2_dqbuf, are supposed to use the DECLARE_EVENT_CLASS and DEFINE_EVENT macros instead of duplicated TRACE_EVENT macro calls.

* v4l: Export enums used by tracepoints to user spaceSteven Rostedt (Red Hat)2015-04-081-25/+50
| | | | | | | | | | | | | | | | | | Enums used by tracepoints for __print_symbolic() are shown in the tracepoint format files with just their names and not their values. This makes it difficult for user space tools to know how to convert the binary data into their string representations. By adding the use of TRACE_DEFINE_ENUM(), the enum names will be mapped to their values and shown in the tracing file system to let tools convert the data as necessary.
