Debugging kernel and modules via gdb¶ The kernel debugger kgdb, hypervisors like QEMU or JTAG-based hardware interfaces allow to debug the Linux kernel and its modules during runtime using gdb. Gdb comes with a powerful scripting interface for python. The kernel provides a collection of helper scripts that can simplify typical kernel debugging ...

Boost the Reliability of the Linux Kernel: Debugging ...

Unlike other operating systems such as Windows or macOS, Linux chooses to present details explaining the crash of the kernel rather than display a simplified, user-friendly message, such as the BSoD on Windows. A simplified crash screen has been proposed a few times, however currently none are in development.

Finding Linux Kernel Bugs with Syzkaller: Debugging the Kernel pt2

The demand for capable debuggers is always high, and being able to handle a versatile set of debuggers is mandatory if you’re looking for high-paying computer science jobs. Since Linux offers a variety of debuggers for different purposes, beginners often find it hard to choose the appropriate solutions for them.

Kernel (operating system) - Wikipedia

The Linux kernel, developed by contributors worldwide, is a free and open-source, monolithic, modular (i.e., it supports the insertion and removal at runtime of loadable kernel objects - LKM), Unix-like operating system kernel.. It is deployed on a wide variety of computing systems, such as embedded devices, mobile devices (including its use in the Android operating system), personal computers ...

Kernel debugging can be performed using either kdb or kgdb. For the sake of simplicity, in this chapter, we will only focus on kdb. The program comes with a shell-like interface, and you can use it to inspect memory, registers, process lists, kernel log, and set breakpoints.

Kernel Configuration - an overview | ScienceDirect Topics

In the previous installment of How to Survive Embedded Linux – How to Debug your Linux BSP – we worked through some issues you might face trying to get your Linux BSP to boot for the first time. This touched on some kernel debugging. In this part of the series, we’re going to take those skills a little further.

Kernel space: Finally, a kernel debugger for Linux ...

Debugging the linux kernel using gdb. The majority of day to day kernel debugging is done by adding print statements to code by using the famous printk function. This technique is well described in Kernel Debugging Tips. Using printk is a relatively simple, effective and cheap way to find problems.
