It'll require ~20GB of space by itself, so if your tmpfs is in RAM, make sure you have enough free, and it's definitely not recommended to use this on a <32GB RAM machine.
Reportedly, multiple games (mostly Unity based, but not only?) are seeing much higher CPU usage at lower tickrates resulting in degraded performance when CPU bound.
300 Hz and less are the worst offenders, but 500 and 750 Hz are also affected to some extent. CacULE is seemingly less efficient than everything else and needs 2000 Hz to keep up in those scenarios.
OS (kernel, CONFIG_HZ) Min Average Max
Arch Linux (linux, 300 Hz) 81% 91% 96%
Arch Linux (linux-zen, 1000 Hz) 21% 25% 42%
Fedora Linux (linux (Default), 1000 Hz) 20% 25% 53%
1000 Hz isn't an issue on modern systems, but older or very weak CPUs (like Atoms) which aren't used for gaming might want to use lower values. Since our main target audience is gamers, it only makes sense to change the defaults here.
* prepare: auto-fetch latest versions + harmonize kernel version var
- Latest version is fetched from git: this prepares the road to
moving to git cloning and fetching
- Introduce the $_kver variable that follows a three digit
convention (e.g. '600', '519', '504') to enable comparing
simply between kernel versions

* All distros: use git to fetch/update kernel sources
- Force git cloning `linux-tkg` so the patches and config
files are automatically checksummed
- Arch: remove all the sha256sums and source files and automatically
populate them on script run.
- Move git cloning/fetching script to 'prepare' script file

keys in _kver_subver_map are hash-ordered, which is not the
natural ordering

Making `make` prompt wasn't working on my Gentoo for a
reason I don't understand anymore. The configs are unset
by the script. So it always goes for generic by default.
Maybe they need to be entirely deleted from the .config
file.

The last one is kinda broken, and the two others don't really have their place in here.
Also enable zfsfix by default and make it a legacy option we can move out of the main options.

Using a kernelconfig.new with a LOCALVERSION set makes the script

They are not needed for DKMS
and that was the only point to why they were there to begin with
