TUTORIALS 》 Linux Kernel Tasklets | Big-Picture | vs User-Space 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 architecture. You can schedule Tasklet(s) for a registered function to run later. So typically the Interrupt top half (of the interrupt handler) performs a small amount of critical work (not to be confused with critical section), and then schedules such as a tasklet to execute later at the bottom half.

Not just that, when we say Kernel Module, its a vaguely defined term. The term "Module" (as we know) is nothing but a collection of APIs, bunch of variables and associated data-structures. Which may or may not be a plugable kernel module.

So here is my detailed multi-episode Youtube video series on Linux Kernel Tasklets, a big picture and a quick demo of my sample code (a Linux Kernel module) comprising tasklet.

I also conduct sessions/classes on Systems and Network software programming and architecture. If you are interested, click HERE for more details.

What is purpose of Kernel Development - Example SMOAD Networks SDWAN Orchestrator Firewall Kernel Engine ↗
Monday' 18-Jul-2022
Often aspiring students may have this question, that what is the purpose of Linux Kernel Development. Since Linux Kernel is very mature and it has almost everything one would need. Usually, we need custom kernel development in the case of any new driver development for new upcoming hardware. And this happens on and on. But at times we may also come across few features/modules/components which are already provided by the Linux Kernel which are not adequate or atleast not the way we exactly intended to use. So, this is the real-world example, sometimes no matter what Linux Kernel provides as a part of stock Kernel/OS features, sometimes we have to write our own custom kernel stack or module(s) which can specifically cater our exact needs.

Roadmap - How to become Systems Software Developer ↗
Friday' 13-May-2022
When you are at the beginning of your career or a student, and aspire to become a software developer, one of the avenues to choose is to become a hard-core Systems Software Developer. However it is easier said than done, since there are many aspects to it as you explore further. As a part of systems developer, you can get into core kernel space developer, kernel device drivers developer, embedded developer and get into things like board bring-up, porting, etc, or can become a user-space systems programmer, and so on. So here is my detailed multi-episode Youtube video series on Roadmap - How to become Systems Software Developer.

Linux Kernel /sysfs Interface ↗
Saturday' 14-May-2022
/sysfs is one of the most popular kernel to user-space interface which you can leverage to add an interface to your Kernel code such as Kernel modules, Kernel Device Drivers, etc. Although personally I prefer /proc interface than other alternatives such as /sysfs, ioctl() and so on for my personal Kernel modules/stack. So here is my detailed multi-episode Youtube video series on /sysfs Interface.

Linux Kernel Data-Structures ↗
Saturday' 13-Mar-2021
Here is a quick reference of important Linux Kernel Data Structures of various assorted Kernel Subsystems such as: Process, Memory Management, Networking, File System, Device Drives, IPC and so on. So when you write custom Kernel code, it is often you may need to populate a new instance of one of these data-structures or just access the existing ones. Hence it is very important to know some of these and get familiarized with. You can bookmark this page, so that you can use this as a quick reference when you write your own custom Linux Kernel Modules.
