/* A simple program to test the communication between the matrox meteor
* driver and an user application in the continous sync capture mode.
*
* First the driver clears the mask and decrements the counter like it
* would in a normal application. Then it purpose does not handle these
* responsibilities to simulate an application falling behind. I use
* the HUP signal to work as if the some of the buffers were removed
* (the second couter is used to cleared the correct bits.
*
* build kernel with at least:
*
* options "METEOR_ALLOC_PAGES=301"
*
