when I type lsmod I get the output below. But I am missing all the other but the sound modules. Why are no other modules shown? I am using the latest Raspbian release (12/16/12)

root@raspberrypi:~# lsmod

  • What more modules were you expecting? lsmod only shows the currently loaded modules, not the available modules. So as long as there is no process that uses a certain module (i2c for example) it will not be loaded and thus not be shown in lsmod.

  • I am missing modules for the ethernet or graphics module for example.

  • My guess on those two modules is that they are directly compiled into the kernel being non-removable from the print anyway.

You are probably mixing lsmod with modprobe.

man lsmod:

lsmod is a trivial program which nicely formats the contents of the /proc/modules,
showing what kernel modules are currently loaded.

man modprobe:

-l --list List  all  modules  matching the given wildcard (or "*" if no wildcard is given).
