Why Linux Kernel is written in C-language but not in C++ ? #TheLinuxChannel #kernelprogramming
Although the current Linux Kernel source-code contain certain parts of the code written in assembly code (actually native CPU assembly instructions) and recently certain parts of code written in Rust…
Systems Programming – Kernel Crash vs User-space Process Crash
A crash in User-space process (say something like segmentation fault) happens just in process virtual memory address space vs a crash in Kernel space (such as Linux Kernel which is…
Linux Kernel Tasklets – Big-Picture vs User-Space Threads (pthreads)
Linux Kernel Tasklets and Work queues are somewhat similar to user-space process threads in terms of the functionality and of course not in terms of its operation or its internal…
Kernel customization via make menuconfig – Linux Kernel Compilation (or a Kernel Build)
Here is a detailed YouTube video on Linux Kernel custom compilation and customization via make menuconfig interface
Smart NIC Cards
NIC Cards (Network Interface Cards) traditionally contain controller chip which takes care of the core aspects, such as packet reception, buffering (till they are read by OS device drivers), etc.…
What is a Linux Kernel Module – a Big Picture
Learning Linux Kernel Programming is always fascinating and yet challenging. So generally you may tend to learn Kernel Module programming, since such a module can be dynamically plugged into running…
Layer-2 (L2) Multicast Frame Deep Analysis
When you learn networking and network software programming, you learn various aspects of networking. Along with datacom concepts such as network switches, routers and so on. As you learn Ethernet…

Linux Kernel Programming – File Operations or FOPs – struct file_operations
Whenever you do Linux Kernel programming, you must've noticed file operations are defined with respect to certain data-structures. Its quite common you may find these in Linux Device Drivers and…
