gamemode binary package in Ubuntu Mantic ppc64el

 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 use 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.
 .
 This package is a metapackage including everything that is necessary to run
 gamemode-enabled games or to enable it by hand for applications. It includes
 a program called '/usr/games/gamemoderun', which can invoke gamemode into any
 application. It also includes '/usr/games/gamemode-simulate-game', which
 invokes gamemode, sleeps for 10 seconds and then exits. This allows you to
 test whether gamemode is working properly on your system, it will return
 gamemode's error message if something went wrong, otherwise it will exit with
 a 0 status.
