    Re: High CPU Load

    Re: High CPU Load

    I submitted a pull request with the change incorporated.

    If anyone is curious, here are the steps:

    git clone https://github.com/UDOOboard/Kernel_Unico.git
    cd Kernel_Unico
    git remote add imx6-dongle https://github.com/imx6-dongle/linux-imx.git
    git fetch imx6-dongle
    git cherry-pick b8a4b014ead3840271b00948b4970051b13e4ff2

    Then build the kernel as described in http://udoo.org/download/files/Document ... 0_2013.pdf

    root@imx6-qsdl:/lib/modules/3.0.35-gdfb7761-dirty# w
    18:45:58 up 2:15, 1 user, load average: 0.49, 0.40, 0.42
    USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT
    ubuntu pts/0 192.168.1.213 16:31 0.00s 0.38s 0.26s sshd: ubuntu

    Load average is way down and the system seems a little more responsive now too

    Re: High CPU Load

    Sure, https://dl.dropboxusercontent.com/u/863 ... -dirty.tgz

    To install it, here are the steps:

    1) tar -xzf udoo-quad-3.0.35-gdfb7761-dirty.tgz
    --- warning, creates a dir called 'udoo'
    2) cd udoo
    3) sudo cp /boot/uImage /boot/uImage-old
    4) sudo cp uImage /boot
    5) sudo cp -a lib/modules/3.0.35-gdfb7761-dirty /lib/modules
    6) shutdown -r now

    This kernel is the default udoo config. At least on my board, the sata port does not seem to show the disk ( there is one ;) ). I have not had time to debug it

    Thanks! The load is resolved... :)
    Now I need to dive into the overall slowness of the linaro :-D

    Hi Taillo

    Technically, that patch should be safe for the udoo dual.
    Would be nice if you could post any feedback on that

    cheers

    Re: High CPU Load

    As I see from the feedbacks, the patch works fine so it will be added to the next releases!

    Yes, no issues at all with this patch - many happy UDOO'ers in IRC have applied this.
