Description
User space processes can be debugged using gdb. With gdb you can
- single-step,
- stop,
- resume,
- put break-points,
- inspect memory and variables,
- look through call stack information
What if we can use gdb on running Linux Kernel.
Problem:
How can a gdb debug running kernel as it is just a user space process.
Solution:
Client/Server Architecture
User space programs can be debugged remotely using the combination of gdbserver on the target machine and gdb on the host machine/development machine.
The Linux kernel has a GDB Server implementation called KGDB. It communicates with a GDB client over network or serial port connection
In this course we will learn:
- How to setup KGDB
- Various ways of getting the target into development machine
- Setting Breakpoints
- Printing and Setting Variables
- Using a single serial port for both kgdb and console messages
- Getting the kernel messages in gdb window
- Debugging Linux Kernel Modules (In-Tree, out of tree)
- Use of GDB Scripts present in the Linux Kernel
Who this course is for:
- Kernel developers interested to learn various debugging techniques
Requirements
- Should have basic knowledge of Linux Kernel
