[gentoo-user] Listing kernel modules
Afternoon all, Is there a straightforward way of listing kernel modules that exist but haven't been loaded? I'm sure I have quite a number that I don't need, and I'd like to remove them from the kernel config. -- Regards, Peter.

This will do I guess:
# lsmod | awk '{print $1}' > inserted
# find /lib/modules/$(uname -r) -name '*.ko' -printf '%f\n' | sed
's/\.ko$//' > present
# cat inserted present | sort -u

Wait, no, replace the last line with:
# cat inserted present | sort | uniq -u

I'm sure I have quite a number that I don't need, and I'd like to remove them from the kernel config. How about just grepping for them under /lib/modules/version? In my case it would be *.ko.xz. Note that won't tell you about anything built in to the kernal you might want to remove. Otherwise, it's just a slow slog through make xconfig or make menuconfig. I suppose you could also grep through the kernel's .config file (or /proc/sys/config.gz) for "=m". In both cases, you probably still need to search to figure out where in the configuration that gets set.

Very good - thanks. Now I have a 183-line list of module names to go through.
:( And of course, the module names differ from the corresponding config
options.
Still, it does give me some useful pointers to bunches of modules I specified
to find out which one I needed.
