The 3D pipeline has to be emptied before you can enter 2D immediate mode. My solution is to leave the coprocessor always running and convert everything to use the DMA based commands. - 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/
