A key part of kernel operation is communication with hardware devices inside and outside of the physical computer. However, it isn't practical for an OS to interact with every possible device in existence. Instead, kernels rely on the ability of device drivers, which add kernel support to spe...
A Kernel is the core component of any Linux based operating system. It represents the core aspect of the Linux distributions for Desktop computers and servers. It has a monolithic architecture, and the operating system operates entirely in the kernel space. The monolithic kernel not only encircles...
While they all have the Linux kernel in common, various Linux distributions build their own operating systems on top of the basic open-source foundation. Linux distributions, referred to as “distros,” boast a range of backgrounds and features. Ubuntu is the world’s most popular free OS and...
The Linux kernel is a free, open-source kernel that forms a critical interface between the hardware and software layers in a computer's OS.
The /proc/vmcore file is thus one of the most common sources for kernel core dumps. The data is represented in ELF (Executable and Linkable Format), which we will discuss a bit more later on. However, if you were to go searching on your Linux machine for a /proc/vmcore file, you pr...
What Is a Linux Kernel? The Linux kernel is central to the Linux computer operating system. The kernel is the core interface between a computer's hardware and its processes, making sure there is available memory for Linux applications to run, optimizing processors, and navigating system requiremen...
1) Linux Kernel Lockdown The principal feature addition on Linux kernel 5.4 is the kernel lockdown mode which aims to enhance Linux kernel security by separating the userland and kernel code. The kernel lockdown limits the root (UID 0) account access to kernel features that enable arbitrary co...

What is embedded Linux? We’re now in a better position to look at the opening question, “What is embedded Linux?” There are three levels at which we can attempt an answer: The system The kernel (i.e., the core of the OS) The distro The system Intuitively, an embedded Linux syste...
What is the Linux Kernel? In OS architectures, thekernelis the core interface between a machine’s hardware and its software. The kernel’s operation is invisible and not directly accessible to the end-user. Instead, most desktop users are familiar with applications within theuser spaceof an ...
