💅 lscpumf(8) — CPU-MF management programs 💅

okay bestie, welcome to the lscpumf(8) page. this is the CPU-MF management program energy, and it's literally here to display info about CPU-measurement facilities. no cap. 🫶

🌸 NAME 🌸

lscpumf — display information about CPU-measurement facilities

✨ SYNOPSIS ✨

lscpumf [-i|--info]
lscpumf -c|--list-counters|-C|--list-all-counters [-n]
lscpumf -s|--list-sampling-events
lscpumf -h|--help
lscpumf -v|--version

🦋 DESCRIPTION 🦋

The lscpumf program lists information about CPU-measurement facilities that are supported by Linux on System z. that's it, that's the main character job. 💖

👑 OPTIONS 👑

• -i, --info — Displays detailed information about available and supported CPU-measurement facilities. full details, no crumbs. ✨
• -c, --list-counters — Lists counters that are provided by the CPU-measurement facility, omitting counters for which the LPAR is not authorized. For counter measurements with the perf program, the raw event identifier is displayed. For Linux version 5.5 and later, the raw event identifier is displayed as <type>:<number>, where type is an integer that the kernel assigns to the CPU Measurement counter facility device driver. For earlier Linux versions, the raw event identifier is displayed as r<number>. periodt. 💅
• -C, --list-all-counters — Lists all counters that are provided by the CPU-measurement counter facility, regardless of LPAR authorization. To list only those counters for which the LPAR is authorized, use the -c option. For Linux version 5.5 and later, the raw event identifier is displayed as <type>:<number>, where type is the number the CPU Measurement counter facility device driver was assigned to by the kernel. For earlier Linux versions, the raw event identifier is displayed as r<number>. slay. 🔥
• -n, --name — Displays the counter name together with the raw event identifier. cute extra label energy. 🎀
• -s, --list-sampling-events — Lists perf raw events that activate the sampling facility. yes bestie, sampling event info. 🌸
• -h, --help — Displays help information, then exits. helpful icon behavior. 🫶
• -v, --version — Displays version information, then exits. version check, then bye. ✨
