The first attempt to get symbolic event name support into perf was sent in 2010, that's FIVE years ago [1]. And what complicated feature are we asking for? The ability to map a human readable name to a hex code, it has the complexity of a first year programming assignment. Variations have been submitted by IBM [1], by Facebook [2], now by Intel, and Google have just given up and carry the libpfm4 patch in their perf tool [3]. Can we please just get this merged. If you *then* want to add support for perf auto-updating that's fine, but don't conflate the two. cheers [1]: https://lkml.org/lkml/2010/3/11/146 [2]: http://article.gmane.org/gmane.comp.linux.perfmon2.devel/2912 [3]: https://github.com/David-Levinthal/gooda/blob/master/gooda-analyzer/perf-patches/linux-v3.17/0001-perf-tools-add-support-for-libpfm4.patch _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
