I am new with CentOs, and more familiar with small linux kernel Sdk. I would like to ask if it is possible to kernel debug ( and kernel module debug in particular) CentOs kernel module, and how ? I am using I7 Intel architrecture.
You can install the kernel-debug package with the same version of the kernel that you are debugging, it’ll contain a vmlinux built the same as the non-debug version, just with the debugging symbols included.
Thanks for this value information! As to the steps after prepearing vmlinux for debug: I also find the following important link: https://github.com/AltraMayor/XIA-for-Linux/wiki/Debugging-the-Linux-kernel But it seems that the kernel debugging metod described there is quite complex (qeuires virtualbox , nfs shared folder). I just wander if this is the method which is recommended & used for kernel module debugging.
Are you interested in debugging a kernel crash core? or use some of the kernel trace/probes to examine a running kernel?
I am intereseted in debugging a new kernel module which I will write (v4l pci express module)
