We could do, or the DRM driver could provide DMA methods for the framebuffer driver to use. I mean it might be that we should always be using DMA methods in all the drivers for radeon all the time anyway ? The fb driver gets told when DRI comes and goes which means the two can choose to co-operate if they wish. - 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/
