NAME
gamemoderun - invoke gamemode into any program
SYNOPSIS
gamemoderun PROGRAM
DESCRIPTION
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 li-
brary (gamemoded and libgamemode), and the client loaders (libgamemod-
eauto and gamemode_client.h) that allows for safe usage without worry-
ing about whether the daemon is installed or running. This design also
means that while the host library currently relies on systemd for ex-
changing 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.
USAGE
libgamemodeauto.so.0 can be pre-loaded into any program to request
gamemoded begin or end the mode, like so:
gamemoderun ./game
Or by setting the Steam launch options for a game:
gamemoderun %command%
The library can be manually preloaded if needed:
LD_PRELOAD=$LD_PRELOAD:/usr/\$LIB/libgamemodeauto.so.0 ./game
CONFIG
It is possible to set additional start commands to gamemoderun by set-
ting the environment variable:
GAMEMODERUNEXEC="command"
When this is set, gamemoderun will execute the command given by that
environment variable, and the command line passed to gamemoderun will
be passed as arguments to that command. GameMode will not be applied to
the wrapper command, just the game itself.
