Revision as of 19:19, 23 October 2009
| DATE | WHEN | WHERE |
| 2009-10-22 | From 12:00 to 21:00 UTC (8am -> 5pm EDT) | #fedora-test-day (webirc) |
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 ...
- Development - Phil Knirsch, Marcela Maslanova (marcela on irc), Petr Lautrbach, Jiri Skala (skalnik on irc)
- Quality Assurance - Jan Scotka

Disk space
Please make sure you have enough space on your disk. You will need
Please make sure you have enough space on your disk. You will need
kernel-debuginfo package whis is about 250MB large!
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).
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).
- An installed Rawhide (development version of Fedora) with graphical environment. Alternatively, you may install Fedora 12 Beta and update your system.
- SELinux isn't needed, users don't have to enable it.
- Internet connection
- The special-purpose Test Day RPM package which includes necessary dependencies and provides all testing scripts.
- Download the package for your architecture: (i686, x86_64, ppc, ppc64)
- Download the package public key and import into RPM:
su -c "rpm --import testday-20091022.asc" - Lastly, install the package using:
yum --enablerepo=rawhide-debuginfo localinstall testday-pm-0.6-1.fc12.YOURARCH.rpm
- Kernel debugging info:
- Install the required package:
debuginfo-install kernel - Alternatively, you can install the debuginfo kernel using
yum:yum --enablerepo=rawhide-debuginfo install kernel-debuginfo - NOTE - be sure that the kernel-debuginfo version matches your kernel version. You can confirm by running the command
rpm -q kernel-debuginfo-$(uname -r)
- Install the required package:
- 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. 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.
Battery
Please charge your battery before performing any test.
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 |
| alpm | A simple test to determine effect of SATA link power management settings on power consumption. | 10 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 below.
File uploading
The
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!| User | Smolt Profile | Results file | ALPM result | Comments & problems |
