Ananicy-cpp-rules for CachyOS

This is a ananicy-cpp-rules collection for ananicy-cpp maintained by the CachyOS team.

Ananicy-cpp & ananicy-cpp-rules

• ananicy-cpp - daemon that automatically adjusts the nice levels of processes.
• ananicy-cpp-rules - list of rules used to assign specific nice values to specific processes.

The nice value determines the priority of a process, with higher values indicating lower priority and making the process "nicer" to other processes. By default, on Linux workstations, the nice value is set to 0.

How to contribute

You can add your favorite games, apps, and more. Any help would be greatly appreciated!
For example, let's say you want to add a game.

1. Go to 00-default
2. Go to games
3. Create a new file with the same name as your game, for example, gamename.rules

Examples of rules

The first example is simple. In the second example, it is different because some games generate multiple processes. In such cases, you need to add all the processes related to the game.

1. Example rule for Just Cause 2

# https://store.steampowered.com/app/8190/Just_Cause_2/
{ "name": "JustCause2.exe", "type": "Game" }

2. Example rules for The Outer Worlds

# The Outer Worlds https://store.steampowered.com/app/578650
{ "name": "Indiana-Win64-Shipping.exe", "type": "Game"}
{ "name": "TheOuterWorlds.exe", "type": "Game"}

3. Example rules for Portal 2 which is Linux native game

# https://store.steampowered.com/app/620/Portal_2/
{ "name": "portal2_linux", "type": "Game" }

How to find out proper process name?

Here is a list of tools

CLI

• htop
• btop

GUI

• System Monitor KDE Plasma or GNOME

GameMode + ananicy-cpp = bad idea

GameMode and ananicy-cpp both adjust the nice levels of processes. However, combining both tools is not recommended, and we strongly advise against doing so.

ananicy-rules's Issues

Feature Request: Please add rule for scx (sched-ext)

The scx programs are part of the sched-ext kernel scheduling program. Because of sched-ext schedulers are running in user space environmemt, so it's nessary to set a higher priority.

The scx programs are come with scx_xxx (xxx is the schedulers name, like scx_bpfland)

For now CachyOS have these schedulers by default: scx_bpfland scx_lavd scx_nest scx_rlfifo scx_rusty scx_userland scx_central scx_layered scx_qmap scx_rustland scx_simple

[Feature request] Add license for this project

Now this repo doesn't contain a license. Could you please add the license info?

Why is htop / btop is BG_CPUIO?

Those are highly interactive tools, and setting them such a low priority makes them nigh unusable under heavy CPU load.

This is especially ironic, considering they are the tools you would use to renice some CPU-hungry processes if it doesn't happen automatically already.

Feature Request: Please add microsoft-edge browser rules

Porting some of rules from original project

Since https://github.com/nefelim4ag/Ananicy/blob/master/ananicy.d/ is archived, would you be open to moving some of rules form there to your project? I'm thinking about only rules which do alter nice/ionice levels, and without creating new mappings (meaning: reusing your existing mappings from 00-types.types. I could tackle this in a few category based PRs.

Feature Request: Please add rule for obs-studio.

Obs-studio is a screen recorder used for streaming also.
As, it is recorder so low latency and high priority should be given.

Process name: obs
