Kernel modules#
Some drivers of the Linux kernel are not loaded automatically, but come as so called
kernel modules.
SimpleCore™ brings all the necessary tools to work with kernel modules.
Kernel modules currently in use#
To check the kernel modules currently used run
$ lsmod

Information about a kernel module#
To get more information on a specific kernel module run
$ modinfo <path to kernel module>
# or
$ modinfo <kernel module filename>
e.g.
$ modinfo /lib/modules/5.10.35/kernel/net/sched/act_gact.ko
filename: /lib/modules/5.10.35/kernel/net/sched/act_gact.ko

Load a kernel module#
To load a kernel module run
$ modprobe <path to kernel module>
# or
$ modprobe <kernel module filename>
e.g.
$ modprobe /lib/modules/5.10.35/kernel/net/sched/act_gact.ko
# or
$ modprobe act_gact
Unload a kernel module#
To unload a running kernel module run
$ rmmod <kernel module filename>
Exit the top session
the kernel module filename can be extracted from Kernel modules currently in use
