Debugging the linux kernels using gdb

The majority of day to day kernel debugging is done by adding print statements to code by using the famous printk function. Using printk it as it is relatively simple and effective and cheap technique to use. There are many other linux based techniques that take the debugging and profiling approach to a higher level. On this page we will discuss using the gnu debugger to do kernel debugging. Overall starting using gdb to do kernel debugging is relatively easy


and work most of the time. One reason for using these ancient techniques this can probably be found in the roots of the Linux kernel (i386) and the tools available to debug those.On the Embedded side we are better served with hardware assisted tools to debug software.
