Stupid Operating System
SOS is a simple, tiny toy OS implemented in Rust.
I'm writing this mostly for fun, to learn more about OS design and kernel hacking, so don't expect anything new or exciting out of this project.
Inspiration, and a reasonable amount of code, taken from @phil-opp's great series of blog posts on the subject, Charlie Somerville's rustboot, and Samy Pessé's How to Make an Operating System.
- POSIX compliance is not a goal (though it would be cool)
- Hybrid/loosely microkernel (i.e., move code to user space when convenient/practical)
- Possibly provide the Rust stdlib at the OS level.
- JVM-style memory allocation?
- Possibly experiment with a Plan 9-esque networking stack eventually?
building & running
I've included a simple
Makefile to automate building and running SOS. This README lists most of the important make targets, but there's also a
$ make help command, which will print a list of all available targets.
setting up your build environment
In order to build SOS, you'll need to properly configure your build environment. Since this process is fairly complex, I've provided some automatic installation shell scripts to make it a bit more painless.
$ make envwill install and configure build dependencies
If you don't trust the scripts, or if you're curious to know what they're doing, you can also follow the manual install instructions in
building & running the OS
$ make kernelcompiles & links the kernel binary
$ make isomakes the kernel and builds a bootable ISO image
$ make runcompiles the kernel, makes the ISO, and boots QEMU from the ISO
