Description

This test case tests the basic functionality of tuned tool. This tool can statically and dynamically tune your system according to selected profile.

Setup

  1. Check that you have Package-x-generic-16.pngtuned package version 2 or newer installed:
    $ rpm -q tuned
    There must be installed tuned version 2 or newer (but not 1) and tuned-utils subpackage.
    • If not install it:
    # yum install tuned tuned-utils

How to test

  1. Start tuned (via systemd):
    # systemctl start tuned.service
  2. List all available profiles:
    # tuned-adm list
  3. Try to switch between profiles, e.g. for powersave profile:
    # tuned-adm profile powersave
  4. Check if the profile was really set by:
    # tuned-adm active
  5. Try several other profiles.
  6. Try to generate tuned profile from powertop's suggestions:
    # powertop2tuned test-profile
    In this generated profile all powertop's tunings are initially disabled, you can selectively enable them by editing /etc/tuned/test-profile/script.sh.
  7. Try to switch to generated profile:
    # tuned-adm profile test-profile
  8. Switch back to balanced profile:
    # tuned-adm profile balanced
  9. Remove generated profile:
    # rm -rf /etc/tuned/test-profile
  10. When done switch tuned completely off by:
    # systemctl stop tuned.service
  11. Check if the tuned process is not left running by:
    # pgrep -l tuned

Expected Results

  1. No errors while switching / generating profiles.
  2. No left tuned process when switched off (ksmtuned not counted).
