What to test

We'd like to check power management tuning available for Fedora-12.

If you come to this page after the test day is completed, your testing is still valuable. You can check whether you save some energy after applying tuning.

Who's available

The following cast of characters will be available testing, workarounds, bug fixes, general discussion ...

Prerequisite

Stop (medium size).png
Disk space
Please make sure you have enough space on your disk. You will need kernel-debuginfo package whis is about 250MB large!
Note.png
Live systems
We prefer testing on installed system. It is almost impossible to test on LiveCD because of required disk space. If you decide to test on LiveUSB, please, add a note into results table about this (into HW column).
  • Rawhide (development version of Fedora) with graphical environment
  • SELinux disabled
  • Internet connection
  • The special-purpose Testday RPM package (i686, x86_64 ppc ppc64) which includes necessary dependencies and provides all testing scripts.
    • Download and install with: yum --nogpgcheck --enablerepo=rawhide-debuginfo localinstall testday-pm-0.5-1.fc12.YOURARCH.rpm
  • Kernel debugging info:
    • Use debuginfo-install kernel or install it manually. (In case of manual installation, you have to enable debug repository in /etc/yum.repos.d/fedora-rawhide.repo.)
    • Versions of kernel and kernel-debuginfo must be the same. Please check it with:
      • uname -r
      • rpm -q kernel-debuginfo
  • Upload your hardware to Smolt according to these instructions.

Running the tests

Update your machine

It will be needed rawhide machine. Howto install or update Rawhide.

Tests

The test cases are split into test groups. Some of the tests are a bit time-consuming. Please perform as many tests as possible. If you aren't able to run them all, please remember that the tests in each table are sorted by importance in descending order.

You don't have to download any special scripts for each test. Our Testday package provides following commands:

  • testday-run-testname (performing tests)
  • testday-pack-results (packing results of all tests in .tag.gz file)

There is a note about permission in the description of each test. Most of the tests can be performed as a normal user. Only a few need superuser permissions. Please follow this information.

X Window System

These tests should be performed on all systems in X11 environment.

Testcase Description ETA
personal Typical use of computer (do whatever you are doing usually). CPU states and frequencies. 10 minutes
scomes Ticks, syscall count, read/written bytes when performing some specific tasks. 1 minute

Single mode

These tests should be performed in single mode.

Refraining reboots
We recommend reading the description of both tests and performing these in sequence - to refrain more reboots.
Testcase Description ETA
tuned CPU states and frequencies when tuning daemon enabled 7 minutes
basic Stress situations (BZIP2 compression, disk copying, vsftpd test) 2 minutes

Laptops

Following tests are intended only for laptops. If you don't have a laptop, don't perform these tests because they are based on capacity of a battery.

Important.png
Battery
Please charge your battery before performing any test.
Testcase Description ETA
bltk Power consumption during three simulated workloads (idle, OpenOffice, reader). 15 minutes
tunedprofiles Tuned profiles effect on power consumption. 5-20 minutes

Results

  • Send your Smolt profile if you haven't done it already (see Prerequsite).
  • Create compressed file with results by running: testday-pack-results
  • Upload created file to this wiki.
  • Add your results into the table bellow.

File uploading
The testday-pack-results will create file /tmp/testday-091022-your-public-smolt-profile-uuid.tar.gz. This name should be unique. But pay attention when uploading it - do not overwrite somebody else's file!
