fxprof-perf-convert

A converter from the Linux perf perf.data format into the Firefox Profiler format, specifically into the processed profile format.

Here's an example profile of Firefox. And here's a profile of the conversion process of that example. Both of these profiles were obtained by running perf record --call-graph dwarf and then converting the perf.data file.

Run

% cargo run --release -- perf.data

This creates a file called profile-conv.json.

Then open the profile in the Firefox profiler:

% profiler-symbol-server profile-conv.json   # Install with `cargo install profiler-symbol-server`
