KYLIN-PROCESS-MANAGER-THAWER(1)

📦 version 4.10.0.1, in ubuntu resolute, ubuntu stonking

✨ NAME ✨

kylin-process-manager-thawer — bestie, this is the lil tool that unfreezes your frozen user processes. That's it. That's the job. (原话是「解冻被冻结的用户进程的工具」💅)

It lives in section 1, aka User Commands, so you already know it's something you run yourself, not some background ghost.

🫶 SYNOPSIS 🫶

kylin-process-manager-thawer

No args. No flags. Just vibes and a thaw. ✨

💖 DESCRIPTION 💖

Okay so. kylin-process-manager-thawer is part of the Kylin OS process management suite, and its whole entire personality is taking user processes that got frozen and thawing them back to life. It does this by poking the cgroup freezer controller, flipping every user-session-related process in the system from frozen state back to normal running state.

The way it works, step by step, no gatekeeping:

  1. It checks whether the cgroup v1 freezer controller directory (/sys/fs/cgroup/freezer) even exists. Like, hello? Are you there?
  2. It walks the user-related cgroup hierarchy (the user session directories under user.slice). Strolling. Taking notes.
  3. For the user service directories that match the naming convention, it sets the state of their cached process group (app-cached.slice) to THAWED. Iconic. Slay. 🧊➡️🌊

This thing usually shows up when your system is coming back from hibernation or a low-power state, or literally any time you need to restore user process resources that got frozen earlier. It's the "wake up babe" of system tools. 💅

⚙️ OPTIONS ⚙️

  • None. Zero. Nada. This script takes no extra command-line options — when you run it, it automatically thaws all user processes. It's a "trust the process" situation fr fr. 🦋

🌈 EXAMPLES 🌈

Thaw every frozen user process on the system:

kylin-process-manager-thawer

That's the whole example. Short king. 👑

📁 FILES 📁

  • /sys/fs/cgroup/freezer — the cgroup freezer controller root directory, where all the freeze/thaw state management lives.
  • /sys/fs/cgroup/freezer/user.slice/ — the cgroup hierarchy directory for user-session-related stuff. This is where it goes looking for your sessions.
  • freezer.state — the state file inside a cgroup directory. Writing THAWED into it means "unfreeze these processes, bestie." ✨

📝 NOTES 📝

  • This script only works on systems using the cgroup v1 mechanism. v2 girlies, this is not for you, sorry. 😭
  • You need root privileges to run it, because it's editing cgroup config. No root, no thaw. Periodt.
  • It only touches the user-session-related cached process group (app-cached.slice). Nothing else gets its ice melted. 🧊
