Can't make the date?
If you come to this page after the test day is completed, your testing is still valuable, and you can use the information on this page to test, file any bugs you find at Bugzilla, and add your results to the results section. If this page is more than a month old when you arrive here, please check the current schedule and see if a similar but more recent Test Day is planned or has already happened.

What to test?

Today's instalment of Fedora Test Day will focus on Power Management

Who's available

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

• Development - Jaroslav Škarvada (jskarvad)
• Quality Assurance - Jan Ščotka (jscotka)

Note: jskarvad will be available during CET business hours (UTC+1) on #fedora-test-day, #fedora-power, #fedora-devel, otherwise he will be on e-mail with non guaranteed response time.

Prerequisite for Test Day

• An updated Fedora 15 pre-release or you may get LiveCD, (special PM test day live image will be prepared later).
• Your hardware profile uploaded to Smolt according to these instructions

Typing convetions

In the following text commands that needs to be run as root are prefixed by #, e.g.:

# id

means to run id command under the root account. Commands prefixed by $ do not need to be run under the root account.

How to test?

Focus on pm-utils, powertop, tuned. Some test cases are only for laptop users and it is signalled in test case description field. If you do not have laptop just skip them. You can also skip other test cases (e.g. if you do not have enough time). In this case just leave the columns for skipped test cases blank. Please note that your report will be still valuable even if you do not finish all test cases. The procedure:

• Run test cases bellow.
• Report results to the result table.

Prepare your system

Install the PM Test Day support package that will setup your system for this test day. It will install all required dependencies, packages and utilities. It will also setup your system to use the PM Test Day repo. This repo contains temporal fixes for bugs discovered and resolved shortly before test day (these fixes will get into F15 soon).

1. Install the public key (in case you would like to verify the PM Test Day support package, otherwise you can skip this step because the public key will be installed automatically with the PM Test Day support package in the next step):

   # rpm --import http://jskarvad.fedorapeople.org/RPM-GPG-KEY-pm-test-day

2. Install the PM Test Day support package by:

   # yum install http://jskarvad.fedorapeople.org/pm-test-day-1-1.fc15.x86_64.rpm

   • This procedure will also install the public key which will be then used for verification of packages from the PM Test Day repo.

Finally make sure you have all current updates (and temporal fixes) installed by:

# yum update

Tuned perf idle	Measures energy consumption of machine in active idle with tuned throughput-performance profile.	Laptops only	15 minutes
Tuned perf load	Measures test duration / energy consumption of machine under load with tuned throughput-performance profile.	All, laptops preferred	5 - 30 minutes

Known Bugs

The following bugs are known, please do not report them again. If you update your system from the PM Test Day repo, you shouldn't encounter them

• RHBZ #684854 - It is about missing tab bar in PowerTOP 2.x.
• RHBZ #663995 - It is about SELinux AVCs during suspend / hibernate.

Test Results

If you have problems with any of the tests, report a bug to Bugzilla usually for the component pm-utils, or powertop, or tuned. If you are unsure about exactly how to file the report or what other information to include, just ask on IRC and we will help you. Once you have completed the tests, add your results to the Results table below, following the example results from the first line as a template. The first column should be your name with a link to your User page in the Wiki if you have one, and the second should be a link to the Smolt profile of the system you tested. For each test case, use the result template to enter your result, as shown in the example result line. bugreport.txt will be generated by test case pm-bugreport, instructions for uploading are included in this test case. The bugreport.txt gives us valuable information about your HW / SW configuration and debug log of your last suspend / hibernate process.
