you need to debug a module that is loaded manually), then the timing doesn't really matter. In my case, I needed to break at something during boot, so after some deciseconds, I ran the gdb command.

On another terminal, from inside the Linux kernel tree, supposing you want to start debugging from start_kernel: gdb \įor kernel modules see: How to debug Linux kernel modules with QEMU?įor Ubuntu 14.04, GDB 7.7.1, hbreak was needed, break software breakpoints were ignored.

Qemu-system-x86_64 -kernel arch/x86/boot/bzImage \ Then on the Linux kernel: git checkout v4.15 To get started from scratch quickly I've made a minimal fully automated QEMU + Buildroot example at: Major steps are covered below.įirst get a root filesystem. Step-by-step procedure tested on Ubuntu 16.10 host So my question is: What should I do to run the kernel on Qemu, attach my debugger to it and thus, get them work together to make my life easier with kernel development. I know that I have to use remote debugging on the port 1234 (default port used by Qemu), using the vmlinux as the symbol table file for debugging. Which launch the kernel in "stopped" stateģ) Thus I have to use gdb, I try the following command: gdb. config)Ģ) Once the compilation is over I run Qemu using: qemu-system-x86_64 -s -S /dev/zero -kernel /arch/x86/boot/bzImage So what I did so far was:ġ) To compile the kernel with: make defconfig (then setting the CONFIG_DEBUG_INFO=y in the. I'm using eclipse as an IDE to develop on the kernel but I wanted first to get it work under QEMU/gdb. So what I did was to follow this tutorial.

I'm actually reading Robert Love's book but unfortunately it doesn't help the reader on how to install proper tools to run or debug the kernel. I'm new to kernel development and I would like to know how to run/debug the linux kernel using QEMU and gdb.
