nice

the colors are very eye torturing

at least for me

not bad code

wait

oh nvm

i thought its kernel shell for a second

though are you sure you wanna use mb2 ans 32 bit in 2026?

just a QoL note

you should test it on all emulator you can

bochs, vmware, qemu,

and your pc (with csm i think its possible)

ld.lld -m elf_i386 -T linker/linker.ld -o build/coffeeos.elf build/boot.o build/kernel.o build/gdt.o build/idt.o build/gfx.o build/keyboard.o build/kshell.o build/pmm.o build/interrupt.o
ld.lld: error: undefined symbol: memcpy
>>> referenced by gfx.c
>>>               build/gfx.o:(draw_braille_cell)

very nice

average clang trying to do its own thing

btw

you are using host gcc to compile!?!?

plus, make sure that the script knows about grub2-mkrescure

'like on fedora (just switched in the morning)

its grub2-mkrescue

very standard os overall

if you want it to be better

switch the bootloader, and go long mode

[low glen]

okay i will try implementing it as fast as i can

[slate heath]

Finally NO KERNEL SHELL!!! proud of you @low glen

[boreal glen]

PEAK

[low glen]

thx

[low glen]

I would love your guys input.. What do you want to see in the OS? If I can, I will prioritize to get it done fast! and probably learn something from it also

[boreal glen]

better mm

[low glen]

i switched to

which x86_64-elf-gcc
/mnt/d/toolchains/coffeeos-x86_64/bin/x86_64-elf-gcc

[boreal glen]

better

plus add support for clang using --target=x86_64-unknown-none-elf

[boreal glen]

please dont hardcode this as always

[boreal glen]

clang is superior

[low glen]

okayy

[boreal glen]

the reason why i tell you to add clang support is people wont compiler that they wont use just to test out your os

[low glen]

ohh okay

[boreal glen]

though keeping it work on both compilers is a bit of work

like my kernel is basically locked to clang

though im trying to add gcc support

though definitely not keen on it

btw you created your account today??

[low glen]

yea

i am kinda new to this

[boreal glen]

np just take your time

theres a lot to this

[low glen]

ohh i know i almost faint while looking at the OSDev Wiki

[boreal glen]

interesting build system

[low glen]

luckily i am 16 and probably will live a long life

[boreal glen]

fair

[boreal glen]

why is it repeated so much?

the flags

and compiler

[low glen]

??

[boreal glen]

assuming justfile is similar to makefile

you can reduce this

into a few lines

[low glen]

i asked claude to generate the justfile

[boreal glen]

tf

[low glen]

since i heard it is newer than make

[boreal glen]

llm are good at this

[boreal glen]

and used basically nowhere

[low glen]

yea

[boreal glen]

or very rare

[low glen]

i wanted to try it out from this : https://youtu.be/_aQ8xJ5DuHY?si=E6uYITuU7SFIpGoa

[boreal glen]

the thing is

just isnt actually a build system

its like ninja

its a command executor

[low glen]

ohh

so what should i do now?

[boreal glen]

theres no reason to switch

but refactor the thing man

[low glen]

on it

[boreal glen]

you are not updating 200 lines to add just a flag

some flags you may find usefuk for kernel compliation

https://github.com/assembler-0/AeroSync/blob/main/cmake%2Faerosync-compile.cmake

btw some needs runtime support

prob overfkill imo

[low glen]

ohh

[boreal glen]

the keyboard driver will likely overflow

try slamming the keyboard on startup and see if you can type anything in qemu

[dire girder]

what's the difference?

like checking which files need to be compiled again which don't?

[calm sapphire]

Are you sure you understand what you're writing, or is AI writing it for you

[low glen]

yea i can understand if not i ask it to explain

[low glen]

unlike this guy: https://discordapp.com/channels/440442961147199490/1471870285207568588

i ain't fully vibe coding the os

[calm sapphire]

Well, you have some well questionable comments around the OS.

[low glen]

which one

[dire girder]

wicks when the project has fucking ai comments

[low glen]

i did change it if its in the cpu folder

this is frm github

this one from vscode

[calm sapphire]

No, well this comment implies you have nooo idea what youre doin

[low glen]

it stopped working in VirtualBox

worked in qemu

[calm sapphire]

Do you even know what an ISR is?

[dire girder]

i mean it probably shouldn't work in either cases

[low glen]

Interrupts

[calm sapphire]

🙏

[calm sapphire]

and an interrupt is?

@dire girder dont give him the answer yet

[dire girder]

lmao ok

[low glen]

a signal frm the input device to the cpu to

[calm sapphire]

ehmm well, ill take that.

[dire girder]

not necessarily input device

[low glen]

tell it stop whatever it is currently doing and do something else

[calm sapphire]

and why doesn't the keyboard work?

when you don't handle the keyboard interrupt?

[low glen]

becuz i had 2 diffrent isos

i had one is windows vbox

and qemu in wsl like that

[calm sapphire]

Are you joking??

[low glen]

nope

[calm sapphire]

If you don't handle the keyboard interrupt it wont work

Noo shit

[low glen]

ofc

[calm sapphire]

why even comment about it?

[low glen]

??

[calm sapphire]

are you joking?

[low glen]

nope

idk what is even happening

why are we arguing

[calm sapphire]

Why comment about a thing that's absolutely no-shit moment. Like ohh wonder why the keyboard handler doesnt work when i remove the keyboard handler call? huh??

[low glen]

prob becuz ai did it and i had to change it

i told u i use AI

i have like lil to no experience

I AM 16

[calm sapphire]

And i am 14?

[low glen]

false

ur elder than me

so i have to repect u

*respect

[calm sapphire]

http://wiki.osdev.org/Required_Knowledge

[calm sapphire]

Do I need to send you a picture of my passport for you to believe me?

[low glen]

no

why do i need ur passport?

[calm sapphire]

For you to believe that Im 14?

[low glen]

nah actually are u 14?

[calm sapphire]

Correct, turning 15.

[low glen]

tf

how are u more skilled that me

probably more experience mb

[calm sapphire]

Well I have around 5 years of programming experience, where one of those is spent doing osdev?

[low glen]

oh great

[low glen]

i have 2 years of exp since my school kinda techs this and may dad is a software engineer

soo

[calm sapphire]

http://wiki.osdev.org/Required_Knowledge

This is not a project for you.

[low glen]

u can expect me to have only like minumum knowlege

[calm sapphire]

I programmed for around 4 years before I even thought about this project.

[low glen]

so imma leave the project and get back to it when i have more exp

cya and thanks for informing

[calm sapphire]

Well it's your project, I'm just saying that it might be a good idea to learn a bit more and make some succesfull user-space programs before you approach a OS.

[low glen]

so should i keep working or gather more info?

[dire girder]

no lowkey you could continue but (ab)using ai will keep you from understanding what happens and why things don't work

[calm sapphire]

Do you have any other significant project under your belt?

[calm sapphire]

No.

It will all come crash down.

[dire girder]

the road is long and hard but also fun and rewarding, use human produced resources

[calm sapphire]

If you haven't made any userspace project don't expect to be able to make a full blown OS:

[dire girder]

yeah c experience and low level understanding is necessary but if he has some it can work out

[calm sapphire]

Currently it doesn't look like that.

[slate heath]

damn @calm sapphire you only 15 😭, i'm 17 with 5 years of general programming experience and almost 2 years in systems programming, you are cookin'

[low glen]

imma keep going ig?

[calm sapphire]

Have you made any substantial projects before?

That's in userspace?

[low glen]

probably not

i might learn more and then try to upgrade this project

not just vibe code into this since that ruins the entire point

[calm sapphire]

Well, keep this on a chill and make some decent sized userspace project and then pick it up again.

[calm sapphire]

Sounds good.

[calm sapphire]

Yea.

[low glen]

thx for the support

[calm sapphire]

np lmk if you need any more help w anything else.

[low glen]

ur bio does say this "DNI if you vibe-code."

[calm sapphire]

Correct.

I made you come to the conclusion that vibecoding a os is not the right thing to do.

[boreal glen]

@calm sapphire did you just suspect another vibecoded project ?

[calm sapphire]

Yep and I was completely right this time, like almost every other time.

[boreal glen]

it is actually vibecoded?

gotta upgrade my ai spotter skills 😭

[calm sapphire]

Scroll up and read the conversation

[boreal glen]

lets see

kinda skipped it

[boreal glen]

lmao

[calm sapphire]

Well that was the thing that sparked my AI senses.

[calm sapphire]

.

[winter thicket]

Kernel Shells are 🔥

[boreal glen]

architecturally, hell no

[boreal glen]

but adrenaline-wise, yes absolutely

[winter thicket]

They’re fun :3

[slate heath]

Nothing is fun when your OS/Kernel isn't architecturally correct

and a Kernel Shell is a HUGE MEGA FAT no-no

[low glen]

??

[boreal glen]

man im drinkin water and see the msg

almost drown

[slate heath]

lmfao

[boreal glen]

though yes

for obvious reasons

[low glen]

ain't a kernel shell a big security risk?

[boreal glen]

not only that

it breaks the kernel - os architecture

[slate heath]

not only security wise, it's not correct and weird. also because the job of the kernel is to ONLY AND ONLY ABSTRACT HARDWARE

[boreal glen]

thats why kernel shells are also called os-in-kernel

[slate heath]

nothing else which USERSPACE can do

[low glen]

ohh

[boreal glen]

a kernel gives a massive api

[low glen]

so basically its
bootloader then kernel then userspace right?

[boreal glen]

for the os to build stuff

[slate heath]

simply yes

[boreal glen]

it should not define how the os look, feel

etc.

[low glen]

so is this the correct order : BIOS/UEFI → Bootloader → Kernel → Userspace

[boreal glen]

yeah

though its general

but thats how it is

[slate heath]

the only think you must remember when working on your kernel, "the kernel NEVER handles things which userspace can already do"

[low glen]

advancement get: KNOWLEDGE

[boreal glen]

e.g. knows how to render a font, fancy graphics

[boreal glen]

in this case, kernel only exposes the draw, ctl methods

userspace drivers use those methods to draw what you see

[low glen]

ohh

[slate heath]

obviously, kernel is only there to abstract and do stuff which is not permitted by userspace

eg. like accessing hardware DIRECTLY

[boreal glen]

yeah

but the reason why you see os-in-kernels are such common

is that

its easier

alot in fact

[slate heath]

fr

people chase easy growth more than correct growth

[low glen]

ohhh

[boreal glen]

for your os

if you want a strong plan

id say start with mm first

[low glen]

mine ain't a kernel shell right?

[boreal glen]

not kernel shell

[slate heath]

nope

[boreal glen]

if its run in userspzce

[low glen]

thank god

[boreal glen]

but you need some modifications to get it out of the os-in-kernel area

[low glen]

which are?

[boreal glen]

loadable modules is one of them

if your os uses a framebuffer,

and its know graphics

and its in your kernel

[slate heath]

#1467786251510743061 MENTIONED

[boreal glen]

and #1452605767185338378 also

[boreal glen]

this guy project is insane ngl

[slate heath]

thanks

[low glen]

both of ur guys project are great

[slate heath]

thx

[boreal glen]

overall, standard project

and pls fix the justfile

[low glen]

are u sure i am ready to get into this project Wicks did say its not for meant for me rn

[boreal glen]

wdym not meant for you? anything specific

[low glen]

for OSDev u need more experience

right?

well rn i do not have the necessary knowledge

imma continue the project well i have more exp about userspaces

[boreal glen]

i mean why not

[low glen]

yea otherwise it ruins the exp if i vibecode my way thorugh this

[calm sapphire]

Ehmm.

Did you really recommend someone to continue vibecoding a kernel.

??

[boreal glen]

what?

i thought he stopped after that?

[low glen]

guys chill i ain't continuing this project until i get more exp

[toxic scaffold]

not really, memset, cpy, … are assumedto exist

[boreal glen]

it assumed exist and it use it explictly

btw isnt that what im trying to say?

[toxic scaffold]

yes… not clang specific

[boreal glen]

it is usually clang

if you compile a freeatanding gcc

it wont likely use it

clang is different

it targets a lot or archtecture and platforms, at once

so it inherits

[toxic scaffold]

??? gcc can do the exact same thing, this is not a clang specific thing

[boreal glen]

freestanding gcc please

x86_64-unknown/none

i already tried

and it did not, in fact ask for mem* functions

[boreal glen]

thats hosted gcc

[toxic scaffold]

on opt level?

[low glen]
