LONGRUN(4)

💖 LONGRUN(4) 💖

ok so bestie, this one lives in the i386 Kernel Interfaces Manual and it's literally all about making your lil Transmeta Crusoe chip chill tf out. it's giving power-saving main character energy, no cap. 🧚✨

🌸 NAME 🌸

longrun — Transmeta(TM) Crusoe(TM) LongRun(TM) support 🦋

✨ SYNOPSIS ✨

okay so LongRun support is literally a whole collection of power saving modes for the Transmeta Crusoe chips, and it's similar in scope to Intel's SpeedStep. iykyk. 💅

the following sysctl(8) MIBs control the different CPU modes:

• hw.crusoe.longrun — type: integer, changeable: yes. this is the LongRun mode, and here are ur options:
  • 0: minimum frequency mode 🐌
  • 1: power-saving mode 🔋
  • 2: performance mode 🔥
  • 3: maximum frequency mode 👑
• hw.crusoe.frequency — type: integer, changeable: no. this is the current frequency (MHz). 📊
• hw.crusoe.voltage — type: integer, changeable: no. this is the current voltage (mV). ⚡
• hw.crusoe.percentage — type: integer, changeable: no. this is the processing performance (%). 🌈

🎀 EXAMPLES 🎀

print the current status, bestie:

% sysctl hw.crusoe

to set LongRun mode to performance oriented variable frequency mode (which means, yes, less power savings — she's hungry now 🔥):

# sysctl hw.crusoe.longrun=2

💜 HISTORY 💜

the Transmeta(TM) Crusoe(TM) LongRun(TM) support first appeared in FreeBSD 4.4. periodt. 💫
