PERF2GV(1)

✨ NAME ✨

perf2gv — bestie, this one converts perf data into a Call Graph 💅

---

🌸 SYNOPSIS & DESCRIPTION 🌸

Okay so the vibe is: you run it like this 🫶

perf2gv < PERF_OUTPUT > CALL_GRAPH.gv

perf2gv is a simple script — like, genuinely simple, not doing anything extra — and what it does is generate a call graph from the perf data you collected on Intel machines using the Last Branch Register (LBR) hardware. No cap, that's the whole job ✨

So you'd collect it like this:

perf record -e branches:u -j any_call executable_under_test

Iconic. Here's an actual example if you wanna see it in the wild 🦋

perf record -e branches:u -j any_call example_prog
perf report --no-demangle | perf2gv > example_prog.gv

💀 Heads up bestie: perf2gv reads from standard input and writes to standard output, so keep those < and > redirects exactly where they are or the whole thing just vibes into your terminal instead.
