Another idea: IIRC ttm has a move_notify callback. So we could simply keep mappings active even when the refcount goes down to zero. Then do the actual unmap either in the move_notify or in the destroy callback. cheers, Gerd _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
