Its an unfair exchange of knowledge and time, and if they > claim they have to make a profit then its even more unfair. also, they seem to do it quite wrong way. i.e. much simpler would be to just implement regular, open driver , and implement additional crypto mechanism in chipset itself, allowing to use simple userspace program sending certified keys allowing GPU to operate. if key is not available and device/driver not paid/registered, then GPU would simply lock itself , similiar to pre-paid designs from company whose name should not be spoken aloud. also certain functionality could be ordered with same chip structure, i.e. framebuffer, unaccelerated 2d, accel 2d, 3d, etc. with user buying proper 'entry level' pre-paid code set from manufacturer. this would provide quite same functionality (profit), without impacting open-source projects like Xorg with unnessesary complications. -- -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
