I'm not sure what exactly you mean by gen2 and gen3 specs, but, as far as I can tell, the GPIO pin assignment is the same for both Cougar Point (Sandy Bridge) [1] and Ibex Peak (?) [2]. Although, the documentation is a bit confusing and it is difficult to tell. [1] http://intellinuxgraphics.org/documentation/SNB/IHD_OS_Vol3_Part3.pdf [2] http://intellinuxgraphics.org/IHD_OS_Vol3_Part3r2.pdf What do you mean exactly by gen2 & gen3? Can you point to docs? > -Chris > > -- > Chris Wilson, Intel Open Source Technology Centre _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
