What are the tools that you have used for debugging the Linux kernel?
The Kernel Debugging Tools for Linux
- Kernel debugger, kdb.
- Kernel GNU debugger, kgdb.
- GNU debugger, gdb.
- JTAG- based debuggers. Of the mentioned tools, the kdb and kgdb were introduced as patches to the kernel code. The plain debugger gdb doesn’t need the patching process with kernel code.
What is kernel-mode debugging?
A kernel-mode debugging environment typically has two computers: the host computer and the target computer. The debugger runs on the host computer, and the code being debugged runs on the target computer. The host and target are connected by a debug cable.
How does a kernel debugger work?
In the kernel-mode debugging case, the target OS is halted and enters the break-in send/receive loop, allowing the host debugger to handle the breakpoint by putting the initial byte back in the breakpoint’s code location before entering the break-in state.

How to debug a Windows kernel driver properly?
- Install Windows 10 to a virtual machine (VirtualBox);
- Turn on Test mode and set BCDEdit as local;
- Install WDK;
- Download OSR Loader;
- Copy files after a building to a VM (C:\DriverTest\TestKernelDriver2\; .cer, .inf, .pdb, .sys);
What are the features of the Linux operating system?
Linux is one of popular version of UNIX operating System. It is open source as its source code is freely available….Basic Features
- Portable − Portability means software can works on different types of hardware in same way.
- Open Source − Linux source code is freely available and it is community based development project.
What is kernel-mode in operating system?
Kernel mode, also known as system mode, is one of the central processing unit (CPU) operating modes. While processes run in kernel mode, they have unrestricted access to the hardware. The other mode is user mode, which is a non-privileged mode for user programs.
