💖 RTKITCTL — the rtkitctl page, but make it cute 💖

okay bestie, you found rtkitctl, the control tool for RealtimeKit, and it lives in section 8 of the System Manager's Manual. it's giving "small command, big responsibility." let's get into it 🫶

✨ NAME ✨

rtkitctl — Realtime Policy and Watchdog daemon control 💅

🌸 SYNOPSIS 🌸

rtkitctl [options]

that's it. that's the whole vibe. no positional args, just options, queen. ✨

🦋 DESCRIPTION 🦋

so here's the tea, bestie: RealtimeKit is a D-Bus system service that changes the scheduling policy of user processes/threads to SCHED_RR (i.e. realtime scheduling mode) on request. 🔥

and why do we care? because it's intended to be used as a secure mechanism to allow realtime scheduling to be used by normal user processes. 🎀 like, regular-user energy but with realtime privileges, and it's all handled safely. slay. no cap.

⭐ OPTIONS ⭐

every single one, bestie, no skips, we don't do that here 💖

  • -h, --help — show a summary of options. the classic "what does this thing do again" move 🙈
  • --version — show version. gotta know what era of software you're living in ✨
  • --reset-known — reset real-time status of known threads. the ones the daemon already knows about, specifically 🎀
  • --reset-all — reset real-time status of all threads. everyone. the whole squad. 👑
  • --suspend — temporarily reset real-time status of known threads. like a lil nap, not a permanent goodbye 😴
  • --resume — restore real-time status of known threads that were temporarily reset by suspend. wakey wakey bestie 🦋
  • --start — start RealtimeKit if it is not running already. no double-starts here, it checks first 💅
  • -k, --exit — terminate the running RealtimeKit daemon. bye boo 💀
heads up: --suspend and --resume are a matched set, okay? resume is literally described as restoring what suspend temporarily reset. don't leave your threads suspended and then act surprised. 😭
