Question

Mention the ways to debug the kernel code.

Answer 1

We can debug a kernel code simply with the command printks. Else we can also use KDB and kernel probes. Other methods are:

• UML (User Mode Linux) – It is the best method for debugging but it does not support device drivers.
• KGDB (Kernel GNU Debugger)
• kdump tools which are used to dump kernel cores.
