Hey!

I have recently started working on a 64bit kernel written in only D (and a little bit of assembly where it is really needed).
I finally got it to boot today in 64bit mode. All it currently do is just print some text and numbers to the screen.

It uses Adam D. Ruppes minimal D runtime, with some small modifications.

I have a precompiled ISO here, if anyone wants to try it: https://github.com/Vild/PowerNex/releases/tag/v0.0.0-ALPHA

The project is fully opensource and located at https://github.com/Vild/PowerNex
I livestream the development of this almost everyday at https://livecoding.tv/Wild/

Hopefully someone will find this interesting.
All feedback is appreciated.

//Dan

So whats the plan?
- 32bit support
- ARM support

What else?

Well, from the README I'd say the goal is a complete x86-64 OS

This project looks great and it's not easy writing a x86-64 bootloader even with GRUB and a reference to work from, Nice work!

Nice!

https://github.com/Vild/PowerNex/blob/master/kernel/src/io/textmode.d#L64 not should be "cast(slot[w*h] *)" ?

Well don't have a fixed plan on what I want to implement.
I might do 32bit, I have not decided yet, but I think I will skip it.

I will not add ARM support because this would require alot more research.
Maybe in the future when PowerNex is in a more feature complete state.

The long term goal is that userspace programs should be able to use phobos.

Ahh neato.
Will you being going down the path of libc/posix compat layer or straight up D all the way?

I want to go D all the way.
But if I have to get a libc, I will try and implement one in D.
