OPHELP(1)

💅 OPHELP(1) — the ophelp girlies' era 💅

okay so real talk, bestie: this is the man page for ophelp, straight out of the General Commands Manual, section 1. she's a command-line girlie from the 4th Berkeley Distribution and she's here to spill literally everything about your performance counter options. no gatekeeping, periodt. 🎀

---

✨ NAME ✨

ophelp — like, she lists OProfile events. that's the whole vibe. 💖

🌸 SYNOPSIS 🌸

ophelp [ options ] [event name]

🦋 DESCRIPTION 🦋

so default behaviour? ophelp just lists the available performance counter options. that's it. that's the girl. ✨

but ngl, the fun part: if you hand her a symbolic event name, she'll return the hardware value for it. like:

ophelp DATA_MEM_REFS

and boom, hardware value, delivered. slay. 💅

🔥 OPTIONS 🔥

• --cpu-type, -c — shows you the events for the numerical CPU type you give it. numbers only, iykyk. 👑
• --get-cpu-type, -r — flips it around and shows you the symbolic CPU name. name reveal moment. ✨
• --get-default-event, -d — shows the default event for the CPU type you specified. the main character event, fr fr. 🌟
• --check-events, -e [events] — checks the given space-separated event descriptions for validity. and if they're valid? she'll show you which pmu counter each event would be assigned to. a whole vibe check for your events. ✅
• --callgraph [callgraph_depth] — uses the callgraph depth to compute the higher minimum sampling intervals for the events. math but make it cute. 🧮
• --unit-mask, -u [event] — shows the default unit mask for the given event. 🎀
• --extra-mask, -E [event] — shows the extra unit mask for the given event. bonus content, bestie. 💜
• --xml, -X — lists events in XML format. for when your parser wants a snack. 🍓
• --help, -?, --usage — shows the help message. the classic. 🫶
• --version, -v — shows the version. 💀

🌈 ENVIRONMENT 🌈

ngl she's low maintenance: no special environment variables are recognised by ophelp. nothing. not a single one. she doesn't want them. 🙈

🧚 FILES 🧚

• $prefix/share/oprofile/ — the event description files that OProfile uses. that's where the lore lives. 📚
