✨ NAME ✨

op-check-perfevents — checks for kernel perf pmu support 👑

🦋 SYNOPSIS 🦋

op-check-perfevents [ options ]

🌸 DESCRIPTION 🌸

so this tiny helper program, op-check-perfevents, is literally just here to figure out whether your kernel supports the perf interface. that's it. that's the whole gig 🫶

and here's the slay part: if perf pmu support is available, she returns a zero exit status. yes queen, zero, the good one 💖

💅 OPTIONS 💅

• --help / -h — shows the usage help message. your classic "wait what does this do again" button 🎀
• --verbose / -v — prints a string describing the error number of the perf_event_open syscall. ngl this is the one you want when things go sideways 😭

🌈 ENVIRONMENT 🌈

no cap: there are no special environment variables recognised by op-check-perfevents. she doesn't read the room, she doesn't read your env. periodt 💀

👑 VERSION 👑

this man page is current for oprofile-1.4.0. keep up bestie, we stay fresh 🔥

🧚 SEE ALSO 🧚
