OP2CALLTREE(1)

📦 version 26.08.1, in debian bookworm, debian trixie, ubuntu jammy, ubuntu noble, ubuntu questing, ubuntu resolute, ubuntu stonking

NAME ✨

okay bestie, say hi to op2calltree — she converts OProfile profiling data into KCachegrind calltree format. that's it, that's the job. 💅

SYNOPSIS 🎀

op2calltree

no flags, no drama, no arguments. she just is. 💖

DESCRIPTION 🦋

so here's the tea ☕ — op2calltree reads the profiling data that OProfile v0.8 spits out and converts it into calltree format so that KCachegrind can actually read it and be the main character.

the OProfile data has to come in on standard input, and you should get it by running:

opreport -gdf

like, that's the pipeline. no cap.

once she's got it, this converter writes out a separate calltree data file for each application, and each one lands in a file of the form oprof.out.<app>. so if you've got multiple apps in there, congrats, you're getting multiple files. periodt. 🌸

also she's not a solo act — this utility is part of the KDE Software Development Kit. 💜

bestie reminder: feed her stdin or she's literally just vibing with nothing to do. 🫶

October 15, 2004 — yeah she's been serving since 2004 and she still ate. that's the KCachegrind / op2calltree energy, iykyk. bye bestie, go profile something 💖✨🦋
