I am modifying the uvcvideo (mainly on the uvc_video.c file) driver to print the timestamp. However, once I compile and load the driver module by
sudo modprobe uvcvideo
and run my video collection program (by Realsense SDK), the CPU usage will become very high. And the dmseg continuously shows this:
[ 400.898175] pwm-tegra-tachometer 39c0000.tachometer: Tachometer Overflow is detected
[ 566.981892] pwm-tegra-tachometer 39c0000.tachometer: Tachometer Overflow is detected
Can anyone help me? Thank you so much!
