I recently discovered that `perf` itself can spit out flamegraphs. My workflow has been: $ perf record -g -F 99 ./my-program
$ perf script report flamegraph
You can also run `perf script -F +pid > out.perf` and then open `out.perf` in Firefox's built-in profile viewer (which is super neat) https://profiler.firefox.com |
