It will report a v4l2_event to userspace during Thanks for the explanation. I read through imx.rst, but it was not clear for me how to actually configure/enable it via v4l2 controls. Could you please provide an example on how I can configure/enable FIM? Also, would you have an example on how to achieve the following behavior explained at imx.rst? "If the FIM detects a bad frame interval, the ipuX_csiY subdev will send the event V4L2_EVENT_IMX_FRAME_INTERVAL_ERROR. Userland can register with the FIM event notification on the ipuX_csiY subdev device node. Userland can issue a streaming restart when this event is received to correct the rolling/split image." Thanks
