In a currently running mt9m111 thread we're discussing ways to activate one of camera's (sensor's) test patterns. A module parameter has been proposed, earlier this has been done by just using the infamous VIDIOC_DBG_S_REGISTER. But then it occurred to me, that there has been previously such a discussion and it has been proposed to assign alternative inputs to various test patterns. So, you just issue a VIDIOC_S_INPUT to switch between the actual video input and one of test patterns. Can anyone else remember such a discussion or maybe just knows examples of such drivers? A couple of grep attempts haven't revealed anything. Is this a good idea?
