I just figured this out, but my print_hex function prints al twice.

Only interface and shortcuts are from GNU Nano. Source code is mine.

I spent a few days refactoring the very early boot parts of my kernel, such as GDT, paging, log initialization, and so on. I vastly simplified it, did a lot of it at compile time as data rather than code, and moved the few parts that must be done at runtime to boot.S, thus fully eliminating the early environment from the C++ code. I delayed the creation of the kernel log and console a bit, and initialized paging and physical frame allocation before it. The only error that can occur is an out of memory condition. Now at kernel log & console creation time, paging and physical frame allocation is fully online, so I can dynamically map framebuffers and data structures.

Using this, I quickly added support for letting the bootloader (GRUB, or any multiboot bootloader) set up a framebuffer, which is used as a console immediately and also for graphical output.

This works quite well on real hardware. Here is a picture of me running my OS in graphical mode on all my personal computers.



I quite look forward to the eventual release of Sortix 1.0 “You actually run this?”.

Really good progress Sortie . Only thing, I see missing in your OS, is networking support. You should implement full networking for version 1.0. Is it available to download with real framebuffer support?.
P.S. My work machine is same as your Silver laptop.

Thanks. Don't fall into the trap of assuming “The only missing thing is X!” because it's not true. Once X is there, you'll find you really need Y, which is more fundamental than X. For instance, networking is important, but it's more important for the OS to be easily installable onto real hardware, that there's a working partitioning tool, that the harddisk drivers work, and so on. I'll prioritize to work on issues that impede being self-hosting the most. Sortix 0.9 has BGA support which is very useful in virtual machines, but there's no scheme for real hardware until now. The 1.0 release is scheduled for December.

I've implemented unix pipes to have a proper standard I/O and also added a small terminal interface:

NewOS is also the name of the os that was used as the base for Haiku. Just saying that if you dont want to get people confused you could think of another name.

@max great work, i'm touched that i have been thanked (:

It's a great honor for me if someone can make good use of something I've made & is interested in making it better, so I like to give something back for this.

Sat down and got my SDL port working again, got prboom built, played some DooM.

klange: You just motivated me again!
