Subject: [PATCH v6 0/6] V4L2 file handles and event interface
Date: Mon, 22 Feb 2010 17:51:23 +0200 [thread overview]
Message-ID: <4B82A7FB.50505@maxwell.research.nokia.com> (raw)
Hi,
Here's the eighth version of the V4L2 file handle and event interface
patchset.
The patchset has been tested with the OMAP 3 ISP driver. Patches for
OMAP 3 ISP are not part of this patchset but are available in Gitorious
(branch is called event):
git://gitorious.org/omap3camera/mainline.git event
The patchset I'm posting now is against the v4l-dvb tree instead of
linux-omap. The omap3camera tree thus has a slightly different
version of these patches due to different baselines.
Some more comments from Hans and Laurent. What has changed:
- Improved documentation.
- V4L2_EVENT_ALL only valid in unsubscribing.
- Events are initialised in v4l2_fh_init() if
video_device->ioctl_ops->vidioc_subscribe_event is defined.
- Event ioctl handlers are called in __video_do_ioctl() iff
video_device->ioctl_ops->vidioc_subscribe_event is defined, no other
constraints.
- Blocking operation for VIDIOC_DQEVENT.
- v4l2_event_subscribe_many() is gone.
- Fixed memory leak in v4l2_event_subscribe()
Comments are welcome as always.
Cheers,
