Title:
gamemode throttles (AMD?) CPUs on exit (powersave governor)
Status in gamemode package in Ubuntu:
Fix Released
Bug description:
* Impact
The CPU governor is forced to 'powersave' when gamemode exists
* Test case
$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
-> get the value
$ /usr/libexec/gamemode-simulate-game gedit
-> close gedit
$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
-> the value should be the same as in the first step
* Regression potential
it's only a config change about the governer selection so it should have
other impact
----------------------------------------
Release: Ubuntu Groovy Gorilla (development branch), but should be the same
in 20.04
Package version: 1.5.1-0ubuntu3
What happens: The not-commented-out line "defaultgov=powersave" in
/etc/gamemode.ini causes gamemode to switch to the powersave governor
on exit rather than reverting to whatever governor was in use when
gamemode kicked in. For AMD CPUs at least powersave is not an
appropriate setting -- the CPU will run slow regardless of demand.
It's nice for when you want some peace and quiet, not so nice for
doing work (or for playing games you haven't configured to use
gamemode).
What I expect to happen: Surely the sane, expected, and user-
respecting behaviour here would be to return the system to the state
it was in pre-gamemode?
