linux-toradex.git/drivers/media, branch tegra-9.12.13 Linux kernel for Apalis and Colibri modules tegra_uvc:graceful exit when usb camera is unplugged 2010-05-07T23:41:58+00:00 Sachin Nikam snikam@nvidia.com 2010-05-05T06:15:54+00:00 17369eee42bba5c1aaaf3a2e9dc79ea55d543e5d Bug 657105 Problem:When the USB Camera is unplugged while preview VIDIOC_DQBUF ioctl hangs in uvc_queue_waiton() as it waits on interrupt which will never come, as USB Camera is unplugged. Solution:Using wait_event_interruptible_timeout() instead of wait_event_interruptible() in function uvc_queue_waiton() with timeout value 250 mSec so as to gracefully exit. With this change VIDIOC_DQBUF ioctl returns error, USB Camera driver handles this error to gracefully exit.

Bug 657105

Problem:When the USB Camera is unplugged while preview
VIDIOC_DQBUF ioctl hangs in uvc_queue_waiton()
as it waits on interrupt which will never come,
as USB Camera is unplugged.

Solution:Using wait_event_interruptible_timeout() instead
of wait_event_interruptible() in function uvc_queue_waiton()
with timeout value 250 mSec so as to gracefully exit.

With this change VIDIOC_DQBUF ioctl returns error,
USB Camera driver handles this error to gracefully exit.
