I'm using Linux 3.5 and an application which builds the pipeline and grabs an image like the "media-ctl" and the "yavta" tools. I configured the pipeline to: sensor->ccdc->memory When I call ioctl with DQBUF the calling functions are: isp_video_dqbuf -> omap3isp_video_queue_dqbuf -> isp_video_buffer_wait -> wait_event_interruptible The last function waits until the state of the buffer will be reseted somehow. Can someone tell my which function sets the state of the buffer? Am I missing an interrupt? Best Regards, Tom
