Thread: using kernel-rt

  1. #1

    Default using kernel-rt

    Hi everybody!

    Im about to buy a hp touchsmart laptop (tx2-1080la) and browsing around about compatibility with linux and stuff, I got to real time kernel in ubuntustudio (im an architect). So I'm thinking about testing it in my new laptop, but at the same time I don't want to change from opensuse since I have been an user for 5 years now and I love it. My questions: is there anyway to test realtime kernel in opensuse? and is it true it improves using graphics apps or it is just for audio apps? I use blender and yafaray a lot, so i want to know if it would improve rendering time and quality.

    That would be all, thanks in advance!

    In openSUSE 11.1, you can install the kernel-trace packages. Those are
    the realtime kernel packages.

    I don't know the answers to these questions - best thing to do would be
    to try. It shouldn't improve the quality of render (since yafray and
    other raytracing software would use the same algorithms to produce the
    end result - so the end result should be identical regardless of the
    kernel being used).

    The RT kernel is just a set of patches applied to the standard kernel.
    Thus, it can be run with any distro. There may not be a standard
    package for openSUSE - I didn't check, but you could still build your own.

    There is a git tree at
    http://git.kernel.org/?p=linux/kerne....git;a=summary.
    With it you would get the latest kernel already patched for RT.

    ok... so I installed kernel-trace... it certainly feels a bit faster...

    is there a way to measure it? what test can i do?

    (now that i know that i can install it on opensuse theres no need to change to ubuntustudio! )

    Probably the easiest measure is to render something using your tools with
    and without the realtime kernel and compare the time it takes to
    complete. :-)
