Hello, I don't know whether the way to restart m2m device after suspend is right or not. To go to suspend state, I think m2m device should stop the job even if there are remained jobs in ready queue. After suspend, driver should restart remained jobs in resume function without ioctl command like: VIDIOC_QBUF.
According the m2m framework, device_run should be called to restart. And the device_run is called by v4l2_m2m_try_run called by v4l2_m2m_try_schedule and v4l2_m2m_job_finish. And v4l2_m2m_try_schedule is only for m2m framework. So in my opinion, if driver didn't call the v4l2_m2m_job_finish in suspend function, the resume function can start from v4l2_m2m_job_finish to restart the remained jobs. Is it right the way or is there anything recommended way ?
