So, trying to use it: $ perf config $ It does nothing, it should either list the configuration values, I think probably showing just what is in the ~/.perfconfig files, i.e. things the user explicitely changed, or show an usage message, like all the other tools, for instance: $ perf stat Usage: perf stat [<options>] [<command>] -a, --all-cpus system-wide collection from all CPUs -A, --no-aggr disable CPU count aggregation -B, --big-num print large numbers with thousands' separators -C, --cpu <cpu> list of cpus to monitor in system-wide <SNIP> 'perf evlist' alternatively does, like perf list, show what a default action: $ perf evlist cycles:pp $ And: $ perf list | head -5 branch-instructions OR branches [Hardware event] branch-misses [Hardware event] bus-cycles [Hardware event] cache-misses [Hardware event] cache-references [Hardware event] $ While 'perf config' does nothing :-\ I suggest you do just like 'perf evlist' and 'perf list'. - Arnaldo -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
