FWIW I've been playing around with it a bit. It seems useful both for scaling problems and likely for performance regression tracking too. Some minor issues I ran into (but no show stoppers): - The error messages for bad -c expressions could be better - I found the requirement for no space after -c unintuitive. - It would be nice to have support for doing the bucketizing per line instead of per function. With a large function and/or inlining it's sometimes hard to identify the actual problem Acme recently added this for perf report. I agree it would be good to merge. -Andi -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
