I haven't checked in detail (we are certainly doing things differently in the non-DRM driver), but the registers seem to match and the GPU is able to render after that. I admit I have not looked much further for now. The only register that does not exist on GK20A is 0x260, but when accessing it Nouveau will be able to continue unharmed after a memory fault. -- 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/
