Agreed. -g could map to fine tuning of callchain parameters like it does right now and we can use -G as a shortcut for inverted callchain keeping the default settings. > Plus it would be nice to allow a .perfconfig flag for people to > configure their desired default reporting parameters. Yeah. It would be also nice to have a "caller" sorting mode: perf report -G -s caller This can be useful to get the entire tree of calls for each callers. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
