GameMode is a daemon/lib combo for Linux that allows games to request a set of optimisations be
temporarily applied to the host OS.
The design has a clear cut abstraction between the host daemon and library (gamemoded and libgamemode),
and the client loaders (libgamemodeauto and gamemode_client.h) that allows for safe usage without
worrying about whether the daemon is installed or running. This design also means that while the host
library currently relies on systemd for exchanging messages with the daemon, it's entirely possible to
implement other internals that still work with the same clients.
GameMode was designed primarily as a stop-gap solution to problems with the Intel and AMD CPU powersave
or ondemand governors, but is intended to be expanded beyond just CPU governor states, as there are a
wealth of automation tasks one might want to apply.
