Debugging Linux Kernel in Deep - Part 1

Debugging Linux Kernel in Deep - Part 1

A traditional debugger allows you to inspect the system state once the system is halted

i.e., after an error has been detected, but doesn’t reveal the events leading to the error.

To understand why an event took place, the relevant context has to be restored. This requires tracing

Tracing is the process of collecting information on the activity in a working system

With tracing, program execution is recorded during run-time, allowing for later analysis of the trace

Tracing provides developers with information useful for debugging.

In this course, we will be learning ftrace, which is the official tracer of Linux Kernel in deep

What can we do using ftrace?
