Commands for reading, loading and unloading drivers on BeagleBone Black?

I am using a BeagleBone Black with Xenomai and RTnet on top. As some real-time programs are not working it could be that the installed drivers on my BeagleBone Black are still the standard drivers and not the real-time drivers.

As I did not find anything on internet (only how to install drivers for Windows when using BeagleBone Black) I would like to ask you if anybody knows a command for BeagleBone Black to read, load and unload installed drivers on BBB?

I have found the commands for read, load and unload driver/modules. See the following output of the command window: the commands are lsmod for reading, insmod for loading and rmmod for unloading.

# lsmod
Module                  Size  Used by    Tainted: G
rtipv4                 18699  0
rtpacket                4179  0
rt_ticpsw              26115  0
rt_davinci_mdio         4570  0
rt_smsc                 2165  0
rtnet                  28479  3 rtipv4,rtpacket,rt_ticpsw
omap_rng                4174  0
