How to setup kernel debugger in RHEL 6.0
Hi, I face up a terrible problem that is for me setting up kdb or any other kernel debugger.
Little background:
I am writing linux kernel driver in C and ASM on host (real) machine that is Linux RHEL 6.0.
I run (I mean debug using printk's) that driver on virtual machine: QEMU, RHEL 6.0 (v 2.6.32-71.el6.x86_64).
I need to watch and modify registers, stack, and memory (because of ASM code).
I found some tutorials, but no one is good for me, because everytime I cannot do some steps.
I have never compiled kernel and generally speaking I am linux beginner
.
Could you help me with some steps?
___
for example this tutorial:
Inside the Linux kernel debugger
I successfully downloaded, unzpied two files (kdb-v4.4-2.6.33-common-1, kdb-v4.4-2.6.33-x86-1).
Unfortunately I even do not have folder /usr/src/linux ^_^.
