Hmm, so maybe just make the split explicit instead of playing tricks with top_bottom? Register the lower vram half as TT_VRAM, register the upper half as TT_PRIV. That'll make sure you never have a big allocation in the middle blocking things. Or maybe add a allocation strategy flag to ttm which effectively does the same. take care, Gerd _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
