NostaluxOS

[split hare]

This is my first operating-system project

[split hare]

did some changes to the start screen

added some commadns

trying to add a filesystem to the OS

[split hare]

system fault

triple fault

[split hare]

lots of bugs

file system implemented

The NostaluxOS architecture is designed for retro-minimalism running on modern 64-bit

1. Core Architecture
   64-Bit Long Mode: This core creates a dedicated 64-bit environment (entry.asm, stage2.asm), utilizing Paging and the Global Descriptor Table (GDT)
   Custom Two-Stage Bootloader: A handcrafted assembly bootloader (MBR -> Stage 2) that manually loads the kernel payload from disk sectors, enables A20, and transitions CPU modes.
   Ring 0 :The kernel currently operates entirely in Ring 0 (Supervisor Mode), granting it absolute control over all hardware resources.

2. Shell and Visuals
   Retro-Console Shell:An interactive command-line interface (shell.c) capable of parsing user inputs and executing system binaries.
   VGA Text Mode Engine: 80x25 character display with 16 foreground/background colors.
   Dynamic Theming: The color and palette commands allow runtime modification of the visual environment.
   ASCII Aesthetics: Includes a rendering engine for the "Nostalux" banner and grid background upon boot (background.c).

3. Storage
   In-Memory Volatile FS: A lightweight, RAM-resident filesystem (fs.c).
   File Manipulation: Supports creating (touch), reading (cat), writing (write), appending (append), and deleting (rm) files.
   WARNING: this storage is non-persistent. Rebooting purges the datastream.

4. System Utilities
   Command History: The system tracks the last 16 commands entered, accessible via the history command or Up/Down arrow keys (keyboard.c).
   System Profiler: The sysinfo command reports detected memory usage and architecture details.
   Kernel Logging: A circular debug buffer (syslog.c) accessible via the logs command, tracking system events and boot milestones.

For how long have you been working on this?

and is it opensource?

[warped canyon]

cool, btw will be there an uefi bootloader

[split hare]

its been like a week or 2 but i was using codex

i stopped using it

now im just using the web editor on github

and it is on github

its open source

[warped canyon]

give a link

[worn schooner]

Yeah, give us the link

[split hare]

https://github.com/ProXgram/RetroOS

@warped canyon @worn schooner im changing from polling to interrupt

[split hare]

@worn schooner donme

done

[worn schooner]

cool

[split hare]

what should i add next

[worn schooner]

ACPI?

if you don't have it yet

[split hare]

i want to work more on ram and filesystem

[worn schooner]

oh get the filesystem done first, i mean that's what i would do

Do you have the basic systems like time?

[split hare]

no

@worn schooner send link

[worn schooner]

link of?

[split hare]

The implementation is located in kernel/shell.c CMOS chip using I/O ports 0x70 and 0x71 to read the BCD values for seconds, minutes, hours, day, month, and year

@worn schooner OS

[worn schooner]

my own OS?

@split hare

[split hare]

yes

[worn schooner]

https://github.com/ShaderHex/ShadeOS #1433902427740049610

the OS is very unorganized and very basic

[split hare]

nice

what does it currently do

[worn schooner]

sooo it has a game, a single snake game

but after making the OS 64-bit it bugged out so it's to be fixed after PIT

it has a small shell with few commands

kernel panic screen

just the basic ones to be honest

[split hare]

@worn schooner i will checjk

you ahve a monolithic kernel loaded via the Limine bootloader

@worn schooner 1. Remove the infinite tick-printing loop so the shell can start
2. Mask IRQ1 on the PIC. This prevents the keyboard from firing interrupts allowing your shell.c polling logic to read keys safely without crashing the CPU

#include "core/software/shell.h"
#include "core/PIT.h"
#include "core/idt.h"
#include "drivers/panic.h"
#include "drivers/hwinfo.h"
#include <limine.h>

void delay(int count) {
    for (volatile int i = 0; i < count; i++);
}

void kmain() {
    init_framebuffer();

    if (memmap_request.response == NULL) {
        print_string("Memmap not available!\n", 0xFFFFFFFF);
        kpanic("NO MEMMAP");
    }

    print_memmap();
    print_string("\n", 0xFFFFFFFF);
    print_memory_info_detailed();
    print_memory_info();
    //pit_init(1000);    

    print_string("ShadeOS x86_64 Pre-release!\n", 0xFFFFFFFF);

    
    pic_remap();
    idt_init();
    pit_init(1000);
    asm volatile("sti");
    uint64_t time = 0;
    char buf[64];
    while (true) {
        uint64_t t = get_ticks();
        int_to_string(t, buf);
        print_string(buf, 0xFFFFFFFF);
        print_string("\n", 0xFFFFFFFF);
        delay(5000000);
    }

    shell_loop();

    for (;;) {
        asm("hlt");
    }
}

this is your kernel.c

#include "core/software/shell.h"
#include "core/PIT.h"
#include "core/idt.h"
#include "drivers/panic.h"
#include "drivers/hwinfo.h"
#include <limine.h>

void delay(int count) {
    for (volatile int i = 0; i < count; i++);
}

void kmain() {
    init_framebuffer();

    if (memmap_request.response == NULL) {
        print_string("Memmap not available!\n", 0xFFFFFFFF);
        kpanic("NO MEMMAP");
    }

    print_memmap();
    print_string("\n", 0xFFFFFFFF);
    print_memory_info_detailed();
    print_memory_info(); 

    print_string("ShadeOS x86_64 Pre-release!\n", 0xFFFFFFFF);

    pic_remap();
    idt_init();
    pit_init(1000);
    
    // Mask IRQ1 (Keyboard) to prevent crash on keypress.
    // Since shell.c uses polling, we don't want the CPU to jump 
    // to an interrupt handler (which doesn't exist yet) when a key is pressed.
    port_byte_out(0x21, port_byte_in(0x21) | 0x02);

    asm volatile("sti");

    // --- REMOVED BLOCKING LOOP HERE ---
    // The old loop prevented shell_loop() from ever running.
    
    shell_loop();

    for (;;) {
        asm("hlt");
    }
}

[worn schooner]

👍

I'll do that tomorrow

[split hare]

begun work on gui

[worn schooner]

Cool

[split hare]

@worn schooner did u fix

[worn schooner]

I started rewriting the whole interrupt and apparently i just finished writing IDT and working on PIC then IRQ

[split hare]

nice

[worn schooner]

#1433902427740049610

[exotic panther]

nice, did you share source code yet

[worn schooner]

^^

[split hare]

yep

currently trying to get gui to work

I moved from polling to interrupt

and implemented ata

[split hare]

my next plan is to have a working gui

[wet knot]

Cool, I'm pretty sure kernelspace shouldn't handle gui at all though.

So it might be better to reach userspace before starting with gui

[split hare]

yeah i should switch to ring 3 instead of ring 0

[wet knot]

You should implement a scheduler

[split hare]

imma implement kmalloc first

[wet knot]

😭 what ru doin you can't even think about gui when you haven't even got kmalloc

[split hare]

yeah i need to switch from static allocations 😭

to dynamic

[sour pivot]

bruh

[split hare]

im going to be redo gui.demo.c to use linked lists and kmalloc instead of static array

[sour pivot]

kernel guis????

BRUH

[split hare]

@sour pivot im going to switch to ring 3 first

for userspace gui

instead of ring 0

[sour pivot]

yeah, then you need malloc too

[split hare]

my gui is in kernel mode lol

but its really basic

[exotic panther]

...windows called

windows has a kernel based windowing system

[sour pivot]

bruh

[split hare]

@sour pivot @wet knot

implemented kmalloc

and a scheduler

[worn schooner]

In fact windows allows some apps to run on kernel space

Which is a big problem but its just for the sake of backward compatibility

[sour pivot]

anticheats

[exotic panther]

signed drivers, you mean

only signed drivers can run in kernel space, these anticheats just bundle a signed driver with an ioctl like interface

[worn schooner]

Are you sure about that? Well maybe i heard a wrong news, ive also heard that the gui runs on kernel space

[uncut timber]

wrong

[worn schooner]

I see 👀, how about the gui?

[uncut timber]

win32k.sys does run in kernel mode
but originally it was in user mode and was moved into kernel mode for performance reasons

and most people agree that was a mistake

[worn schooner]

Yeah since it can take down the whole OS

[exotic panther]

without this, we likely never would have had proper gaming on the NT line of OSes

cant really do DirectX without it

anyone else remember gaming on NT 4 and even 2000? with its "you need 2x as much ram, and there will be a massive reduction in performance"

[uncut timber]

I mean, didn't those two already have win32k.sys?

[split hare]

nostaluxOS is now ring 3 for the graphical

but there some bugs i need to fix

[wet knot]

Quick progress. One day from kernel to userspace is crazy.

[split hare]

I am building the next temple

this temple will have networking

[wet knot]

What are you on about?

[split hare]

Im continuing the temple

[wet knot]

TempleOS

`?

[split hare]

@wet knot yes

holyC v2.0 will replace C

Desecrating the Altar is the first sstep

[exotic panther]

lol

isnt this kinda like peeing on a dead mans grave

[split hare]

I have gui fully functional

working in ring 3

[wet knot]

Show us an SS

[worn schooner]

Yes, let's see

[split hare]

@wet knot @worn schooner

whats ur time

[split hare]

im further upgrading the gui

[wet knot]

whhhaat

in one day?

How is that even possible?

Well wow, it has been a while since I've seen an whole AI generated OS.

Damn

It's sad seeing though, so much opportunities to learn, so much knowledge all gone.

[worn schooner]

Timezone?

[worn schooner]

Maybe he used the same code from his recent OS?

This was so fast, for me implementing the interrupters alone took me 2-3 days

[wet knot]

Check his repository.

It is overly commented, it has comments like "Fixed {issue} by doing {overly detailed explanation}". Everything with extreme SPAG and the files are 1k lines each. All without any proper structure inside a single folder.

I'm not judging him for using AI, just that for me I feel like it's so much knowledge lost and for me this project is not worth looking at.

[worn schooner]

gui_demo.c consist of syscalls? Interesting...

[wet knot]

Using if else for showing apps.

[worn schooner]

Oh my

I spotted a function that's specifically for handling browser's click

System calls as well

This all in gui_demo.c

[wet knot]

yea well AI has some quite interesting tweaks.

[worn schooner]

When i first tried to make an os I had to search "how to make windows" and yes english is not my first language. There were no Ai so learning such a thing was much harder (it was pre covid)

[wet knot]

There's a difference between learning how to make an OS and just asking AI to "make an os" and makes it do it for you.

[worn schooner]

True, but AI could really be a useful tool if you use it right

[sour pivot]

only if you already know the topic

or if you wanna search inside a big doc

[wet knot]

So you're implying that saying "make me an OS" is how you use it right?

[worn schooner]

No!

[sour pivot]

it could theorically work

just idk what it would spit out

[worn schooner]

I mean asking Ai about some specific part let's say you want to implement PIT, you dont ask it "make me a PIT for my OS" you ask it to describe it and then later when you check the osdev PIT page, its going to be easier for you to understand

[wet knot]

This.

[worn schooner]

AI is not capable of making an OS

[wet knot]

This is what it would spit out.

[sour pivot]

it is

[wet knot]

This OS is completely AI made.

[sour pivot]

the agentic mode should be able to somewhat do it

with a bit of help

[worn schooner]

I have tried making a simple Minecraft 2d game with pygame as a challenge a year ago and it didnt go well

[sour pivot]

i made it do my elf loader bc i felt too lazy to write

and from what i can see, it should be correct

and integrated correctly with my os

[wet knot]

Lol it seems like its capable enough.

Like this OS is completely AI generated.

[worn schooner]

I have tried making an OS before with gpt 3, and it ended up bad

[sour pivot]

bruh what

[worn schooner]

Well seems like it haha

[sour pivot]

use GH copilot + sonnet 4.5

[wet knot]

@split hare what AI did you use for this OS?

[worn schooner]

Im in third world country, most of the AI's doesnt work here

[sour pivot]

USA?

[worn schooner]

Just chatgpt, deepseek and Gemini and from what I can tell deepseek performs better still not that good

[worn schooner]

USA isn't a third world country

[sour pivot]

i remember some ppl said it became one

[worn schooner]

Anyways my point is you can use AI to describe how some part of something works just not "make something"

[sour pivot]

it can make something from scratch

[worn schooner]

Well I guess he's a good prompt writer haha

[sour pivot]

tho you have to describe it VERY well, and help sometimes

[worn schooner]

Yeah but I dont suggest that

[sour pivot]

and use agents to write code

[worn schooner]

Oh yes, you need to know about that something otherwise letting AI do everything blindly will cost you a lot of time

[sour pivot]

yep

[cosmic needle]

This is misleading. It can't "create". It can however regurgitate the contents of really bad internet tutorials, like half incorrectly, and then generate you a readme with a bunch of emojis on a bulleted list talking about how blazing fast and modern it is

That's what happens to people who try to AI generate an OS

[sour pivot]

depends what AI you use

some AIs are now being trained on actual production code

basically some devs are getting hired to create some real production code to train AIs on

[cosmic needle]

They've been doing that for years lol

[worn schooner]

Pretty sure at least 30% of black ops 7 is written with AI. Since it didn't bother them to put AI generated banners

[cosmic needle]

They are completely useless still if you want to do anything delicate and sophisticated, except for maybe as an supplement to your editor for doing tedious repetitive code editing tasks

I would never ever trust them with program generation

Even if I could I still wouldn't because I actually enjoy things and am not a society-polluting bloodsucking productivity demon lizard person with no soul

[sour pivot]

(and big corps said the AIs will replace devs)

[cosmic needle]

The big corps are evil

and have trillions invested in AI

so yeah they'd say that

[sour pivot]

and then the "AI Devs" nuke amazon and microsoft

[worn schooner]

I don't think it's as satisfying as getting something to work by yourself

[cosmic needle]

It also makes you stupid

[worn schooner]

Oh gosh windows break for every 5-6 updates here. For some reason it decides to remove the VMD driver

[cosmic needle]

The future the AI bros are salivating over involves the average IQ (including theirs) dropping by 20 points globally

[worn schooner]

Don't you all think that's because an AI generated code? I mean clearly they don't purposely do it for every update in a while

[split hare]

Okay okay this os is purely ai generated

But im just finding out how far an ai can go

With building such a project

[cosmic needle]

LLMs literally won't even get us to that level of dystopia though they're a plateaued dead end and the biggest bubble ever is gonna pop when it becomes common knowledge that they invested trillions to make a code editing tool that randomly makes mistakes and doesn't do what you tell it, about 5% better

And that it's not getting any better from here with current knowledge

[worn schooner]

I'm curious, what kind of AI do you use?

[split hare]

Are u impressed

Of what the ai did

[worn schooner]

Kind of

[cosmic needle]

No

Lol

It's very trivial

They've been able to do this for like 2 years already with no improvement

We've seen a million AI generated projects almost identical to this

[worn schooner]

My gpt is oddly dumb. It makes mistake on basic maths calculations

Plus AI's wasn't allowed in my country until 2024

[split hare]

absolutely not

ai built this from scratch\

it did not need any help

It did it without needing to do ANY work

it was purely ai generated

the dynamic memory, gdt, gui, ring 3, everything

it is just ai

i didnt even review the changes

[wet knot]

One prob though

[split hare]

@wet knot everything it was hitting it

[wet knot]

You dont know what it does

and its shitty code

which dosent work

it simulates everything

no ipc

no real userspace impl

so you think it works

but really its just a big if else statement

[split hare]

i literally didnt check the code

its not a serious project

[wet knot]

.

[wet knot]

ik

im amazed how far it has come

but fr this project is trash, both you and me can say so

[split hare]

that was the goal of it

to see how far it can go

but yes it is trash

its not even a real filesystem

But at least it was able to make a nice bootable gui

its really impressive

because years ago ai would not even be able to boot it

damn its really trash

its not even real ring 3 😭

[sour pivot]

loool

[split hare]

its running on one single kmain

[sour pivot]

so it's just a kernel gui

[split hare]

it didnt even properly implement a scheduler and ipc

thats crazy

yeah its just a kernel gui with thousands of lines of code

@wet knot the ai was hallucinating bruh

[worn schooner]

Ai choose the simplest path

[wet knot]

Yes

Thats what im saying

[split hare]

it literally said it was ring 3 😭

[worn schooner]

I have also made an OS that runs apps with if statement (back in 2023)

[worn schooner]

It used cosmos haha

[split hare]

LOL

UI would have slapped in 2005

[worn schooner]

Haha

Oops sorry for the ping

[exotic panther]

I also have used AI sometimes.
to make docs. to help with drivers and collating reference manuals

and even tried to get it to make programs in retro rocket basic (it sucks at this)

and, to identify bugs

don't let it fix them, but it seemed good at finding them

I don't use any agentic bullcrap or any integrated coding ones. just ChatGPT plus.

[worn schooner]

I use it when the error is too long and unreadable so it points it out for me

[split hare]

I am no longer going to change the code

this project is officially closed

im going to be starting a real non-ai generated project

https://github.com/ProXgram/NostaluxOS/

should i just make a new thread?

[sour pivot]

yes

[split hare]

im just gonna overwrite the intro
