A CPU frequency scaling daemon for Linux with no configuration.
# sudo go run *.go
If you append --debug it outputs whatever it's doing so you
can watch the magic on your terminal for a few seconds until
you get bored. It even has emojis!!!
It's very sophisticated. It checks core load. If it's low it goes down. If it's very low it goes even more down. If it's high it goes up. If it's very high, you get the deal.
Oh, and if your laptop is plugged to AC it sets the governor to
performance and doesn't do anything.
If you want to disable it temporarily while keeping it running
create /tmp/clockhead.lock.
That's it. This is the pinnacle of my Linux Power Management knowledge so if you want more features it's very likely I have no idea how to implement them.
The repo has a PKGBUILD script, so Arch Linux users are able
to run $ makepkg -si. The others can run $ go build *.go,
install clockhead (the binary) on /usr/bin and copying
clockhead.service to your favourite systemd directory, e.g.
/usr/lib/systemd/system/. Once you've done that you can run
$ systemctl enable clockhead
$ systemctl start clockhead # to start it
$ journalctl -f --unit clockhead # to monitor it
