which .ko file?

which .ko file?

[peter360]

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.
