Linux Kernel Debugging - Part 1

Intro To Linux Kernel Debugging

This session will provide an overview of approaches to Linux kernel debugging as well as look in depth at a couple selected approaches.

This session will include:

1. Overview: printk, configuring kernel, kdump/crash, GDB with /proc/kcore, KGDB, debugfs, procfs, sysfs
2. Usage and examples of printk(), log levels
3. Configuring the kernel for debugging:

• kernel hacking choices (__must_check, lockups, mutex/lock checks, etc.)
• other DEBUG configuration macros

4. kdump and crash

A subsequent session will cover other kernel debugging approaches.
