After decades of hard work from the Realtime Linux developers, it is finally up for merging, fully and officially, into the mainline tree. With the forthcoming release of the 6.12 kernel we can finally say Linux is officially a Realtime OS. Perhaps the next Linux-based space vehicle can use it, who knows. At the Open […]
A few weeks ago I sent a spelling fix to the Linux kernel, mainly just to try out the patch submission workflow but also because I get mildly annoyed by spelling errors until I have the overwhelming urge to just send a patch. Here’s the cliffnotes of the process. Do your edits in the kernel […]
This is a random collection of things I want to note down about Linux kernel compilation, so that I don’t forget them. One is how to compile a kernel and output to a different directory than the kernel source path. If you Google this, most answers tell you to do something like this (in this […]
When writing an operating system, after you get past the tedium of the arbitrary rituals you need to initialize your hardware, you get to the fun part – designing the abstractions that your kernel will use. One of the things we need to think about is processes and threads. In operating systems textbooks, there are […]
30 years ago today, Linus Torvalds sent out the now-famous email announcing that he was building a free operating system. 30 years later, Linux has taken over the world, from tiny embedded systems to supercomputers and even runs in space, on Mars, and wherever else you can find a computer. I first used Linux in […]
I’m writing several small operating systems for fun (as you do), and to test and debug them I use the QEMU virtual machine. I’m writing this down to collect the bits and pieces of information I need in one place, and so that I can look it up again if I forget, and hopefully will […]
