I can't seem to figure that out. If we can determine that, then we can find the proper place for it in the kernel. Rui, what does this hardware do? What is the interface between the hardware and userspace that this driver is creating? thanks, greg k-h _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
