说明
powertop2tuned turns the recommendations produced by PowerTOP into a runnable TuneD profile, bridging the two tools so that the savings PowerTOP discovers can be applied permanently and rolled back like any other TuneD profile. The utility runs PowerTOP under the hood (or reads an existing HTML report supplied with -i), parses each "Tunable" entry, and emits a profile directory containing a tuned.conf file plus a helper shell script. By default the resulting profile inherits from the currently-active TuneD profile so that base optimisations are preserved; --new-profile creates a stand-alone profile and --merge-profile lets you pick a different parent. For safety, every PowerTOP recommendation is initially commented out in the generated profile. The administrator is expected to review and uncomment only the lines that are appropriate for the target hardware. The --enable flag opts in to enabling all of them, except for ones that the script considers unsafe. The generated profile is activated like any other TuneD profile with tuned-adm profile _profile_name_.
参数
- -i _FILE_, --input _FILE_
- Use _FILE_ as PowerTOP HTML report instead of generating a new one.
- -o _DIR_, --output _DIR_
- Write the generated profile to _DIR_ (default: TuneD's user profile directory).
- -n, --new-profile
- Create a brand-new profile rather than merging with the active TuneD profile.
- -m _PROFILE_, --merge-profile _PROFILE_
- Merge with the named _PROFILE_ instead of the currently active one.
- -f, --force
- Overwrite the output directory if it already exists.
- -e, --enable
- Enable every tuning that PowerTOP suggests. Tunings considered harmful (like USB_AUTOSUSPEND) remain disabled.
- -h, --help
- Show usage and exit.
