Thread: which .ko file?

  1. which .ko file?


    Hi,

    How do I determine the .ko file used for a certain kernel module in a
    running kernel? For example, on my dell laptop I see
    $ lsmod | grep 3945
    ipw3945 230952 1
    ieee80211 65161 1 ipw3945

    $ modinfo ipw3945
    modinfo: could not open /lib/modules/2.6.18-92.1.1.el5/extra/ipw3945.ko: No
    such file or directory

    $ locate ipw3945.ko
    /lib/modules/2.6.18-52.el5/weak-updates/ipw3945.ko
    /lib/modules/2.6.18-52.el5/weak-updates/ipw3945/ipw3945.ko
    /lib/modules/2.6.18-8.1.4.el5/extra/ipw3945/ipw3945.ko
    /lib/modules/2.6.18-92.1.1.el5/weak-updates/ipw3945/ipw3945.ko
    /lib/modules/2.6.18-92.1.10.el5/weak-updates/ipw3945.ko
    /lib/modules/2.6.18-92.1.10.el5/weak-updates/ipw3945/ipw3945.ko

    $ uname -a
    Linux mylaptop 2.6.18-92.1.1.el5 #1 SMP Thu May 22 09:01:47 EDT 2008 x86_64
    x86_64 x86_64 GNU/Linux

    How do I find out which ipw3945.ko file was actually loaded into the kernel?
    thanks!

    I think it's
    /lib/modules/2.6.18-92.1.1.el5/weak-updates/ipw3945/ipw3945.ko, which
    matches your kernel version, right? You could remove it to another
    directory instead
    of current used /lib/modules/2.6.18-92.1.1.el5/, then try "lsmod | grep
    3495". If you
    still could see it, then my guess is wrong. Otherwise, I'm correct.

    thanks for the quick reply. You are right. I did what you suggested, and
    rebooted the computer, now 'lsmod | grep 3945' is not showing anything.
