[RFCv3 00/17] Request API, take three

From: Alexandre Courbot
Date: Tue Feb 06 2018 - 20:48:41 EST


As discussed yesterday, here is a rebase on the media master branch. A
few minor fixes for typos have also slept in, but otherwise this is
equivalent to v2. I expect to have the buffer queueing behavior fixed in
the next version.

Alexandre Courbot (9):
media: add request API core and UAPI
media: videobuf2: add support for requests
media: vb2: add support for requests in QBUF ioctl
v4l2: add request API support
videodev2.h: add request_fd field to v4l2_ext_controls
v4l2-ctrls: support requests in EXT_CTRLS ioctls
v4l2: document the request API interface
media: vim2m: add media device
media: vim2m: add request support

Hans Verkuil (7):
videodev2.h: Add request_fd field to v4l2_buffer
v4l2-ctrls: v4l2_ctrl_add_handler: add from_other_dev
v4l2-ctrls: prepare internal structs for request API
v4l2-ctrls: add core request API
v4l2-ctrls: use ref in helper instead of ctrl
v4l2-ctrls: support g/s_ext_ctrls for requests
v4l2-ctrls: add v4l2_ctrl_request_setup

Laurent Pinchart (1):
media: Document the media request API
