PDF Download: Linux Kernel Internals - A Hands-On Approach to Linux Kernel Architecture and Debuggin

Electronic versions of these documents allow you to quickly get to the information you need and print only the pages you want. The Intel 64 and IA-32 architectures software developer's manuals are now available for download via one combined volume, a four volume set or a ten volume set. All content is identical in each set; see details below.

At present, downloadable PDFs of all volumes are at version 078. The downloadable PDF of the Intel 64 and IA-32 architectures optimization reference manual is at version 045. Additional related specifications, application notes, and white papers are also available for download.

WSL 2 is a major overhaul of the underlying architecture and uses virtualization technology and a Linux kernel to enable new features. The primary goals of this update are to increase file system performance and add full system call compatibility.

Just like any other typical operating system, Linux has all of these components: kernel, shells and GUIs, system utilities, and an application program. What makes Linux advantageous over other operating system is that every aspect comes with additional features and all codes for these are downloadable for free.

Linux kernel development for embedded devices tends to be divided according to the processor architecture in question. For example, Russell King leads a group of developers actively developing Linux for ARM-based devices (via the website ). ARM developers base their work on the original Linux kernel and develop specific patches for ARM. These source code patches allow for new hardware support and fix existing bugs affecting the ARM architecture in the upstream kernel. From time to time, these patches are included in the various kernels through an automated process.The Linux 2.4 kernel is undoubtedly no longer relevant to new embedded projects, as it has long since been superseded by the latest version 2.6. While the 2.6 series kernel is best known for its enhancements for large servers, it also adds a rich set of configuration options for resource-constrained embedded devices.

The basic architecture of the Linux kernel (Figure 1 and Figure 2) has remained unchanged despite the various versions. It is based on a two-level distinction: Kernel Space and User Space. The programs reside in User Space, while the Kernel resides in the Kernel Space. The Kernel can be divided into three sub-levels: system call (read, write), kernel code that does not depend on the architecture and code that depends on the architecture of the system (Board Support Package, BSP). Its architecture can be divided into the following subsystems:

NVMe architecture works out of the box in every major operating system, including all mainstream Linux distributions. Please check on specific feature support with the distros, e.g. Red Hat Enterprise Linux, Ubuntu. NVMe technology has been supported since kernel 3.3, and at the time had been backported to 2.6. Intel released some history of the Linux NVMe drivers stack in 2015 here:

Some distributions make the sources readily available. For example, in openSUSE, you just have to download thekernel-source package. With CentOS, it is a little more difficult, but doable. You can also visit the Linux Kernel Archive and download the kernel matching your own, although some sourcesmay be different from the ones used on your system, since some vendors make their own custom changes.

If you don't have a Makefile, you can invoke gcc manually using all sorts offlags. You will need kernel headers that match the architecture and the kernel version that was used to createthe kernel where the crash occurred, otherwise your freshly compiled objects will be completely different fromthe ones you may wish to analyze, including functions and offsets.

As a long term solution, you could also create symbolic links under /usr/src/linux from the would-be badarchitecture to the right one. This is not strictly related to the analysis of kernel crashes, but if and whenyou compile kernel sources, you may encounter this issue.

If you have time and space, you may want to download and install a debug kernel for your kernel release. Notfor everyday use, of course, but it could come handy when you're analyzing kernel crashes. While it is big andbloated, it may offer additional, useful information that can't be derived from standard kernels. Plus, theobjects with debug symbols might be there, so you won't need to recompile them, just dump them and examine thecode.

NetHunter Lite can be installed on all Android devices that are rooted and have a custom recovery.The full NetHunter experience requires a devices specific kernel that has been purpose built for Kali NetHunter.The NetHunter GitLab repository contains over 164 kernels for over 65 devices. Kali Linux publishes over 25 images for the most popular devices on the NetHunter download page.The following live reports are generated automatically by GitLab CI:

This file must be copied to the /boot directory and renamed in the process. Provided the name is prefixed with vmlinuz-, you may name the kernel as you wish. In the examples below, the installed and compiled A.B.C kernel has been copied over and renamed to vmlinuz-linuxAB:

If your /boot is on a filesystem which supports symlinks (i.e. not FAT32), copy System.map to /boot, appending your kernel's name to the destination file. Then create a symlink from /boot/System.map to point to /boot/System.map-linuxAB:

Linux distribution is an operating system that is made up of a collection of software based on Linux kernel or you can say distribution contains the Linux kernel and supporting libraries and software. And you can get Linux based operating system by downloading one of the Linux distributions and these distributions are available for different types of devices like embedded devices, personal computers, etc. Around 600 + Linux Distributions are available and some of the popular Linux distributions are: 2ff7e9595c
