Hi, > - imo we should fix this by using the io_mapping stuff, that avoids > the overhead of repeated pat checks for map/unmap. 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@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
