What is the difference between kernel drivers and kernel modules?

A kernel module is a bit of compiled code that can be inserted into the kernel at run-time, such as with insmod or modprobe . A driver may be built statically into the kernel file on disk. ³ A driver may also be built as a kernel module so that it can be dynamically loaded later. (And then maybe unloaded.)

What does modprobe do in Linux?

modprobe is a Linux program originally written by Rusty Russell and used to add a loadable kernel module to the Linux kernel or to remove a loadable kernel module from the kernel. It is commonly used indirectly: udev relies upon modprobe to load drivers for automatically detected hardware.

What does lsmod do in Linux?

lsmod command is used to display the status of modules in the Linux kernel. It results in a list of loaded modules. lsmod is a trivial program which nicely formats the contents of the /proc/modules , showing what kernel modules are currently loaded.

What do you mean by kernel module?

Which kernel modules are loaded?

Module Commands

• depmod – handle dependency descriptions for loadable kernel modules.
• insmod – install loadable kernel module.
• lsmod – list loaded modules.
• modinfo – display information about a kernel module.
• modprobe – high level handling of loadable modules.
• rmmod – unload loadable modules.
