I am evaluating the rteval test to see whether it is a useful tool for us.

In the current form, it is not packaged, and depends upon a library which is not packaged.
These instructions only work for Natty and later.

In order to install and run it on Ubuntu (Oneiric), these are the steps:

 1. Install the required packages:
    * sudo apt-get install python-ethtool python-libxslt1 python-dmidecode rt-tests python-dev git

 2. Install python-schedutils from source:
    * wget http://people.canonical.com/~sconklin/rteval/python-schedutils-0.3.tar.bz2
    * tar jxvf python-schedutils-0.3.tar.bz2
    * cd python-schedutils-0.3
    * sudo python setup.py install
    * cd ..

 3. Fetch and install rteval:
    * git clone git://github.com/sconklin/rteval.git
    * cd rteval/loadsource
    * wget http://www.kernel.org/pub/linux/kernel/v3.0/linux-3.1.1.tar.bz2
    * cd ..
    * sudo make install

 4. Run rteval from terminal for generic kernel (for 6 minutes duration):
    * sudo python /usr/local/lib/python2.7/dist-packages/rteval/rteval.py -d360.0 > rteval-$USER-generic-normal.txt
    * this dumps the test results into a text file in your /home directory

 5. Run rteval from console (to check if cgroups affects test) for generic kernel (for 6 minutes duration):
    * clt-alt-F1 (to get to console)
    * log in
    * sudo python /usr/local/lib/python2.7/dist-packages/rteval/rteval.py -d360.0 > rteval-$USER-generic-console.txt
    * this dumps the test results into a text file in your /home directory

 6. Install -lowlatency kernel
    * install abogani's ppa from termainal
      * sudo add-apt-respository ppa:abogani/lowlatency
      * sudo apt-get update
      * sudo apt-get install linux-lowlatency

 7. Reboot

 8. Run rteval from terminal for lowlatency kernel (for 6 minutes duration):
    * sudo python /usr/local/lib/python2.7/dist-packages/rteval/rteval.py -d360.0 > rteval-$USER-lowlatency-normal.txt
    * this dumps the test results into a text file in your /home directory

 9. Run rteval from console (to check if cgroups affects test) for lowlatency kernel (for 6 minutes duration):
    * clt-alt-F1 (to get to console)
    * log in
    * sudo python /usr/local/lib/python2.7/dist-packages/rteval/rteval.py -d360.0 > rteval-$USER-lowlatency-console.txt
    * this dumps the test results into a text file in your /home directory

== Which low latency kernel are we testing? ==

The -lowlatecny kernel is available on kernel.ubuntu.com/git (that is
http://kernel.ubuntu.com/git?p=abogani/ubuntu-precise-lowlatency.git;a=summary).

The -lowlatency kernel uses a different configuration:

And a little patch to force kernel to put IRQ handlers in threads:
