Description of problem:
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. run in 1minutetip environment (no graphic card present or unsupported graphic card)
2. looks like: tuned-adm profile balanced triggers this ERROR/WARNING
2019-07-17 08:20:15,713 ERROR tuned.utils.commands: Error when reading file '/sys/class/drm/card0/device/power_method': '[Errno 2] No such file or directory: u'/sys/class/drm/card0/device/power_method''
2019-07-17 08:20:15,713 WARNING tuned.plugins.plugin_video: radeon_powersave is not supported on 'card0'
Maybe warning or just ignore non presence of gpu?
Agreed that we should not log the error.
I'm not sure yet about the warning - it might make sense to omit it if no GPU is found, however in a sense, it's still unsupported tuning, so a warning is appropriate. I think I'd rather keep the warning, we should not hide stuff like that from the user. The user can always modify the profile if a certain tuning doesn't make sense for their system. However we could print a better warning message such as "no GPU found".
