Day 24 of building a Unix from scratch

It's official

There we go

Why do these blasted serial ports never generate interrupts

Built out a small system for packaging ports in .tar.gz files and dumping them in /dist, plus a small script to automate their installation -- so I can ship some optional package sets.

First one is "devel", which includes make and tcc.

I needed a break from Real Work, so I'm speedrunning writing a Unix-ish operating system

Day 3

The hacking shall continue until we are self hosting

Further day 3 progress

mood

End of day 3

It can read files from the Linux install on my laptop :D

Day 4

End of day 4: ext4 works but needs to be integrated into the filesystem abstraction (which also needs to be fleshed out)

Maybe VFS tomorrow?

Starting to get lwext4 rigged into the Bunnix filesystem abstraction

Work progresses on integrating ext4 with the Bunnix filesystem API

This screenshot brought to you by fs::* rather than lwext4::*

Did anyone else think inodes were black magic when they first got into Unix

What's probably next is fleshing out the VFS a bit, then getting to userspace and implementing a few syscalls

I have a (shitty) VFS

That's probably it for day 5, I have other things to do today 🙂

✓ ELF loader

Day 8: let's write a System-V loader and get to userspace

also: don't write a USB driver don't write a USB driver don't write a USB driver

Day 7, taking a break to hang out with a friend who's in town, more to come tomorrow
