learn vga colors with the microkerneln't

[wild glen]

i ported my stupid pmm debug table to my terminal emulator

i need to allocate some memory for it so i can get more than 80x25

its 80x25 by default idk why it's vga and it should fit on most screens

if it doesnt then destroy computer

[wild glen]

pmm lore

i am not good with words at all

[wild glen]

ok so uh

i got a really funky asf triple fault

i am not dealing with this shit so im gonna make my list have like 16000 entries and refuse to elaborate

ok once i merge free entries i am done with this shit

messed around with color palette

ok i need to get a better color choice

this shit is literally the mac terminal 😭

questionable

[gloomy musk]

https://coolors.co/

[wild glen]

holdup this is fire

[gloomy musk]

yeah it's quite neat!

[wild glen]

beige terminal

might look good

i wanted beige because that's how (more mac :s) the open firmware screen looked on my ibook

though uhhh it's supposed to be white

rip screen

[gloomy musk]

I mean hey it might

[wild glen]

old apple laptops' screens are literally fading out into yellow

if you look at colorful images this is unnoticed but if its like white then it will look yellow

[wild glen]

true

[wild glen]

palette

indigo :0

[gloomy musk]

oooh, that looks really nice!

[wild glen]

didnt use the palette generator though

idk how to add more colors to it

yeah idk im keeping this it looks nice

anyways so im almost done with the pmm then i can turn on paging

then i need to figure out how to use something thats like 3 gb far into the memory

[wild glen]

the startup terminal was originally on the top left but i think this is kinda really dum dum

so i centered it

i can make the black border some other color but it's still centered

no more border

[gloomy musk]

nice 😎

[wild glen]

banger terminal

it should just take up the entire screen but this is really only for boot

[fluid moon]

macos terminal is pretty cool

[wild glen]

true

[wild glen]

yo guys

im done with the pmm

no seriously i finished it somehow

[gloomy musk]

let's goooo!

[wild glen]

paging and vmm time!111111111!!!!!!!!!

(round 3 )

[gloomy musk]

🎉

[wild glen]

ok its on github

[wild glen]

my thing triple faults

it survives for like 10 seconds then dies

now it froze up and doesnt triple fault?

what the fuck is going on

it just sits there menacingly

maybe the framebuffer is hidden somewhere in the world's ass and i have to add it to the page directory?

it literally doesn't output anything it isnt dead

it's just silent

it's the framebuffer i swear

because if i mark all tables as present it doesnt crash

(idk what absolute dumbass marks all page directory entries as present but still)

[gloomy musk]

hmm

[wild glen]

idk it drew some weird lines at the top of the screen

before dying

[gloomy musk]

sounds like improperly mapped framebuffer and/or IVT mayhaps

[wild glen]

ivt??

[gloomy musk]

Interrupt Vector Table

IDT basically

[wild glen]

that's real mode tho iirc

yeah i think it's a framebuffer thing i need its' address

[gloomy musk]

maybe I'm getting my terms mixed up lol

[wild glen]

all good

i thought the framebuffer is in the first 4 mb but i guess not

theas fucking gnoo multibto 2nd

[gloomy musk]

You can just get the framebuffer's address and start mapping there

[wild glen]

yeah ik

ima print the address on the screen first i wanna know where it is

0x3000000 (50331648)

50 mb

i dont think that's the first 4 mb

[gloomy musk]

XD

[wild glen]

i think i already know how to map it

ok yeah ima just map it

i need to update my pmm slightly so it wont allocate 3 gb's in 😭

mildly funky piece of shit

[wild glen]

i can map tables now

[hushed briar]

FloppaOS kernel init face ahh

[wild glen]

i do not see anything wrong with whatever the fuck this is

[hushed briar]

It’s just my kernel init

I just found it funny because of the :meme I put after GDT

[wild glen]

init_gdt()

[wild glen]

AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA

[hushed briar]

ITS FINALLY OK

BRO DIDNIT

DID IT

[gloomy musk]

LET'S GOOOOOOO!

[wild glen]

redemption arc

i can finally do somethi- vmm jumpscare

[fluid moon]

you’re gonna love heap

[hushed briar]

Heap was a banger

Slab allocator 🗣️ 🗣️

[gloomy musk]

Slab is quite fun to implement :3

[hushed briar]

It’s a banger

Free lists of different object sizes 🗣️🗣️🗣️

Everything is a fucking free list at the end of the day

[wild glen]

are they vmm stuffs?

[gloomy musk]

nah, heap allocator (kmalloc basically)

you use it for variable sized objects

[wild glen]

how do i make one and what does it do

[hushed briar]

This font is so clean

[hushed briar]

So basically

[wild glen]

thx its totally not stolen

[hushed briar]

Imagine you were to do a 64 byte allocation

[wild glen]

yes

[hushed briar]

With a page allocator

You would waste

A whole page

For one allocation

[wild glen]

true

[hushed briar]

To mitigate this issue

Which is called fragmentation

You create a list of smaller sized objects

So for example

Make a list of 32 byte blocks, 64, 128. 256

So let’s say you request a 100 byte block

[wild glen]

mk

[hushed briar]

It will give you the block of the closest size

Which in my slab allocator would be 128

Make sense?

[wild glen]

uhhh confused

[wild glen]

are these pages or just "blocks"

[hushed briar]

Well a page is bigger than these blocks

They’re typically called objects

[wild glen]

oh

[gloomy musk]

read this :3 https://people.eecs.berkeley.edu/~kubitron/cs194-24/hand-outs/bonwick_slab.pdf

[hushed briar]

You will split a “page”

[wild glen]

wait i think i figured it out

[hushed briar]

Into blocks of these did

Size

So for example

A slab with a size of 64

[wild glen]

you split a page in halves and then you can allocate a page partially

[hushed briar]

Would divide a whole page

Into blocks of 64

[hushed briar]

Kinda

You create many slabs of different object types

So you have them on standby

[wild glen]

k

[hushed briar]

Rather than requireing a new page allocation each time

[wild glen]

mk

what if something requests more than a page

than just like one page

[hushed briar]

Fall back to pmm

[gloomy musk]

I actually made a diagram but it's way too big XD

[wild glen]

make more pages

make another stack

[hushed briar]

If alloc_size < page size { pmm alloc (size) }

That’s pseudo code

For how you would fall back to pmm

I should at least finish the brackets lol

[wild glen]

lmao

[hushed briar]

Now in my os, I don’t fall back to the pmm

If a heap allocation goes over page size

I created a special allocator for that

Which is just a fee list

Free list

Like this

[wild glen]

i mean i alr have a freelist so i can just somewhat add onto it

or not

ok no wait

[hushed briar]

Yeah

You can

[wild glen]

yeah fair

[hushed briar]

Just take it from your preexisting free list

The only reason I do the free list within my heap is because I don’t want it to be tied to my pmm

For some reasons

[wild glen]

is slab also a part of a pmm or is it something else

[hushed briar]

Mainly subsystem separation

No

A pmm just shits out physical pages

That’s all it does

[wild glen]

yes

[hushed briar]

And frees them

So a slab doesn’t do that

[wild glen]

ok slab is just a fancier pmm that doesnt shit out pages but shits portions of pages?

or smth like that

i think my stupid take murdered the chat

[gloomy musk]

I mean..... yeah pretty accurate

[wild glen]

quite fancy

ima make it so the regular pages get identity mapped first for paging and shit first tho

because inaccessible memory would be really funny but im boring so i dont want to do that

[fluid moon]

make sure to implement address spaces

you’re gonna need it

[hushed briar]

No. Single address space operating systems are peak

[wild glen]

each process gets an address space?

[fluid moon]

yes, child processes clones parent addr space though, while the kernel has its own reserved one

[hushed briar]

Yes

Yeah and for forking the child inherent the parents addr space

fork() is a fucking mindfuck

[fluid moon]

fuck I have to implement fork
I might just have the address space shared between processes instead of implement COW

[wild glen]

wtf is fork()

[hushed briar]

Working on it right now

[hushed briar]

Create an instance of the parents process

[gloomy musk]

no, implement spawn instead

[hushed briar]

Oh GOD

[fluid moon]

I do have sys_spawn

[hushed briar]

don’t do that to him

[gloomy musk]

okie fine XD

[gloomy musk]

ah, coolio!

[hushed briar]

Because it’ll just teach him that he’s better to spawn threads

When it’s not

It’s always better to fork if you can

Not threads processes mb

[fluid moon]

ofc it is

you want the parent to have control over children

[hushed briar]

Yeah

[wild glen]

wdym an instance just duplicate it?

[hushed briar]

Spawning is only for some stuff

[hushed briar]

Yes

But with the parents address space inherited by the child

[gloomy musk]

I presume we're talking in terms of a UNIX-like and not just in general spawning is bad

[wild glen]

wdym by that
the child uses the copy of a parent's address space?

[hushed briar]

No. It uses the address space of the parent

[wild glen]

oh

[hushed briar]

It’s still better to fork

[gloomy musk]

Basically the child uses the same address space of the parent

[wild glen]

then why not just use the parent's address space am i skipping some tier 5932 knowledge here

[gloomy musk]

What's wrong with spawn (kind of curious now)

[fluid moon]

my sys_spawn just creates an asynchronous task independent from the spawner with no inherited trait

which is pretty bad

and used for spawning tasks from the kernel but the user COULD call it, it just shouldn’t and should opt for fork

[fluid moon]

the fact that more resources are allocated for a process that should end when its parents is killed/exists

[gloomy musk]

I should append that by "and not just in general spawning is bad" I mean the process creation mechanism not necessarily POSIX's implementation

[gloomy musk]

ah

[fluid moon]

bash
|> cat

where cat should be dependent from the bash process and die in case of the parent execution end

so you use fork, don’t quote me on any of that though, I’m not the unix expert so I’m not sure if this is the real reason

[gloomy musk]

well, imma do spawn anyhow 🙃

[fluid moon]

if your spawn can link a child to its parent then spawn it is :)

[gloomy musk]

works just fine for Windows, evidently

[fluid moon]

spawn is only bad in you consider it in a unix environment where fork creates a child from its parent and spawn makes an independent task

[lethal summit]

why are we spreading misinformation

it doesn't use the same address space

[gloomy musk]

okie ye in a UNIX environment I could very well see spawn being not so good lol

[fluid moon]

it’s COW

irrc

[gloomy musk]

isn't that fork()'s whole thing?

[lethal summit]

yes but they aren't "the same address space" which is why making variables in the parent won't be seen by the child after fork

implementation wise sure

but that statement makes it sound like they share the same memory and thus parent variables made after fork would be visible by child

[fluid moon]

isn’t it a cloned address space with mappings on access?

I’m genuinely asking

[lethal summit]

yes it starts as a cloned address space but this doesn't mean that it "uses the address space of the parent" throughout the entire life of the child because the child cannot see modifications (such as new variables) created in the parent in the fork

that statement (above) makes it sound like forking allows such things

[fluid moon]

I agree

[lethal summit]

the proper way to phrase it is that the parent address space is cloned at the time of fork, but whenever a parent modifies a page belonging to itself, a copy of the page at the time of the fork is mapped to the child to replace the previous parent page so the child doesn't see parent modifications after fork

[fluid moon]

I’ll end up crazy implementing COW

alternatives?

[lethal summit]

memcpy

[gloomy musk]

that's what I was going to say, but I got distracted by the whole spawn talk lol

[fluid moon]

btw my non unix os is becoming unix-like

I’ve fallen in the osdev pipeline

[gloomy musk]

🥀

[hushed briar]

It inherents the parents address space. Therefore it’s the same. Sure, they don’t share it, but it is a copy of the address space

But yeah my language was unclear

[lethal summit]

💥

[lethal summit]

it also technically doesn't need to "inherit its address space" if you don't do CoW and just memcpy everything over

[fluid moon]

honestly the fact that the unix model is so documented makes it so easy to follow, and seems a more robust implementation than reinventing the wheel

[lethal summit]

🤪

[hushed briar]

that’s cancer 😭

Reminds me of the memcmp acpi meme

[gloomy musk]

true tho

[lethal summit]

we should all use memset to verify that every memory address is zeroed at boot

except for kernel code

[fluid moon]

I’m gonna drop a cringe fact about my kernel lib

[lethal summit]

5 minute boot process with 4 minutes and 59 seconds of memset

satisfying

[lethal summit]

kernel libs when they meet kernel cons

[hushed briar]

My cringe fact is the entire thing

assert.h is a banger tho

[fluid moon]

I can instantiate vectors from C strings and the raw array in that case is a rodata const char*, so every time I delete the object I check if the array address is in the kernel heap region before using ‘delete[] arr ’

[lethal summit]

make custom assert for maximum aura (just kidding I did this because my macOS build was failing because GCC couldn't find assert.h)

(no idea how that happens because it finds everything else just fine)

do asian operating systems call it chopstick instead of fork

[fluid moon]

which I think makes everything slightly slower

[fluid moon]

chopstick()

[lethal summit]

in the true spirit of C++

[lethal summit]

no but it would be 筷子()

[fluid moon]

oh god I have so many syscalls to implement

[lethal summit]

have fun 🤑🤑🤑🤑

[fluid moon]

fork, execve, waitpid

open, read, write

and I don’t even have all primitives to implement them

I still have to write FDs, tables for processes and COW

[wild glen]

1.) i want something that isnt unix!
2.) ok maybe a little bit of unix inspired stuff
3.) ima just make a terminal framebuffer its simpler
4.) ok im gonna make similar system calls to unix
5.) ykw what if i put every syscall on int 80h
6.) ah fuck it lemme make a unix compatible vfs just for shits and giggles

40 steps later

46.) shit i made a unix

[fluid moon]

so real

[wild glen]

i might be at step 3

[fluid moon]

the unix-like vfs saves lives

I’m at step 6 already

[wild glen]

(problem is im considering putting syscalls at 80h

i have fallen to the unix)

[wild glen]

nice

[gloomy musk]

I'm at step 3 probably, don't think I'm going any further tho XD

[wild glen]

https://tenor.com/view/lie-detector-lier-trending-gif-6708574292361340617

[fluid moon]

BUT I don’t want to port gnu or bsd core utils

[wild glen]

ykw i surrender

ts unix now

[fluid moon]

I’ll write my own

[wild glen]

[gloomy musk]

another one bites the dust 🥀

[fluid moon]

my progress report thread went from (not UNIX) to (maybe UNIX)

[wild glen]

i noticed

[wild glen]

saddening

its still a microkernel so im still stuck in hell

if you want to follow a better os go to AssertOS managarm or something

[hushed briar]

That’s what I plan on doing

[wild glen]

i wanna make my own but ill still port them for shits and giggles

[gloomy musk]

I won't cause I wanna keep my sanity somewhat intact

[lethal summit]

will there be oneium and twoium

[wild glen]

wahr

[lethal summit]

null is zero

[wild glen]

oh

didnt get it at first

[wild glen]

no

[wild glen]

wait how do i do page table and page directory stuff without it dying

like i mapped the framebuffer but still im not sure

wait nvm i might have an idea

In 32 bit you would typically do an recursive mapping

Thankfully I have a diagram of this

im not gonna ask why in the fuck its ascii but oh

[wild glen]

so put a pointer to itself at the last page dir?

[hushed briar]

:) yes

[wild glen]

what for tho? (why)

[hushed briar]

It’s in my code

[hushed briar]

Rtm:)

Read the manual

I won’t be rude to you about it lol

Intel sdm

Banger read

[wild glen]

holy shit

i read an osdev wiki article rn tho

i got the point

its always at 0xFFFFF000

[hushed briar]

Yeah

[wild glen]

tmrw ima go figure out the paging management thingies

the recursive mapping and/or whatever other bs exists

slab(?)

[wild glen]

i'm door
john door the ceo of door

ok im somewhat confused about vmm like do processes just have their own specific areas that only they can access

like their own pagedir or smth???

are addresses just remapped? (system ones made inaccessible)

total mindfuck plz help

wait think time

so say a program is loaded at 10 mb
but it thinks its at 5
so 10 mb is mapped to 5
uhhhh is malloc still at 10?

is that pos fully isolated from other programs as well?

like it cant overwrite them

if a program switch happens a remap thing is done

maybe

how is it supposed to be done

trying to read a bunch of address space stuff rn

It is possible to provide each executable with its own address space, so that memory always starts at 0x0000 0000.

nice (source: wiki)

wait

[wild glen]

holy fuck this is cool

[gloomy musk]

System Pages are marked as Supervisor pages (so ye, inaccessible, but still mapped)

[wild glen]

true

reasonable diagram (TM)

this entire thing is an absolute brainfuck

or is it

no nvm its not really

peak osdev

[wild glen]

i figured the address shitamabobs out during the 30 seconds before math period was over

dumb question during an isr interrupt does the system leave user mode

until i finish doing shit with it

[gloomy musk]

pretty sure ye

[wild glen]

ok cool

i needed to ask this or id go insane

i assume thats the only thing that happens and none of the vmm stuff is restored

if the pagedir was modified for a task for example

[gloomy musk]

wdym by "none of the vmm stuff is restored"?

[wild glen]

if the stuff on the page directory was modified for a program like idk address space stuff

shit i dont have any more time this has to stay a mystery now :'(

afk

ima ping u when i come back

[wild glen]

@gloomy musk so what i meant is that say for each progress the pagetable/pagedir is modified slightly
i dont think it will modify itself back to the state the kernel uses it unless i explicitly program to make it do so

no shit moment but yeab

yeah

[gloomy musk]

okie, you usually use different pagetable for each process, and the kernel should be mapped into said pagetable already.

so you wouldn't be switching back to the one you were using on startup

at least I don't think

don't quote me on any of this

[wild glen]

dw that gave me a brainfart anyway i dont think i can do it if i tried

(jk i somewhat get the point

no excuses

he's mentally insane

indeed

why do i associate that emoji with "gdt init ... ok"

[fluid moon]

gdt init… are you OK?

[wild glen]

no

oh god he's crashing out on discord now

[fluid moon]

just download it already

[wild glen]

fine

anyways ima program my vmm

probably

map pages without triple fault

[fluid moon]

remember about address spaces

[fluid moon]

yes, those

[wild glen]

seems quite simple
(this exact moment i am gonna get quadruple fucked by the universe)

[fluid moon]

kinda

https://gitlab.com/utcq/meowix/-/blob/main/kernel/memory/vmm.cc?ref_type=heads

[wild glen]

cc??

[fluid moon]

c++

[wild glen]

oh

[fluid moon]

i prefer it over .cpp

[wild glen]

i thought the file format for that was cpp but mk

[fluid moon]

I was thinking why don’t you port the kernel progress to 64bit

I mean 32bit is really ancient and everything you’ve written until now is compatible with 64bit

[wild glen]

hmmmm

idk

maybe compatibility

tbf anything older than a core 2 duo is absolutely useless at all

and also idt and gdt?

honestly idfk if i should switch to long mode

like actually

can some random ass dude shill me limine for no reason

[grave wadi]

u should use limine

[wild glen]

y

[grave wadi]

that was a threat btw

u SHOULD use limine

[wild glen]

ok

using limine now

[grave wadi]

bet

[wild glen]

wait do i have to rewrite the gdt and idt code

do they have differences

(ik the gdt does)

[grave wadi]

were they written for 32 bits?

if yes then yeah

[wild glen]

yes

[grave wadi]

aint much different tho

[wild glen]

https://tenor.com/view/crying-emoji-dies-gif-21956120

[wild glen]

slightly modify it?

vmm is probably way different

[grave wadi]

yeah you'd need to change the idtr structure, the descriptor structure and the way you push things to the stack when calling the handler

[grave wadi]

I mean it has more levels

[wild glen]

oh god

[grave wadi]

but if u understand 32 bits paging it should be pretty easy to understand 64 bits

[wild glen]

reasonable

shit i have to make an x64 cross compiler

[gloomy musk]

Why? Aren't you 32-bit, did I miss something?

[wild glen]

i got threatened to use limine

to not be generic this is a unixn't

ik big stupid but if it doesnt work im just gonna revert to mb2

[gloomy musk]

Oh okay

[wild glen]

" o k "

64 bit unix like kernel on li-

[gloomy musk]

No wait I'm still confused, are you on a 32-bit machine or something, I thought you only needed a cross-compiler when you aren't targeting your machine's arch

[wild glen]

im on a 64 bit machine

for some reason a cross compiler is necessary for shits and giggles

i can just use regular gcc for cross compiling 32 bit compiling but still

[gloomy musk]

Ah okie

[wild glen]

(also regular gcc has different results)

(some stuff works only on a cross compiler)

[gloomy musk]

Use clang

[wild glen]

W h y

[gloomy musk]

Because I said so, and I'm objectively right

[wild glen]

i expected you to say "that was a threat btw\nUSE clang "

are there any differences between gee cee cee and clang

syntax

in syntax

[gloomy musk]

Uh, i don't think so, maybe ask someone smarter than me lol

I don't like typing on my phone XD

[wild glen]

me neither

it makes me want to commit pain

also i just realized limine protocol advantage

you can set whatever boot resolution you wish

[wild glen]

my pee cee crashed

https://tenor.com/view/crying-emoji-dies-gif-21956120

even qemu updated

The concept isn’t so bad

The implementation is hard if you wanna do it well

[wild glen]

[hushed briar]

Bro hasn’t your whole kernel up until now been ia32?

[wild glen]

yes :/

idrk if i should even do it its not pushed to github yet

ykw im gonna add onto it by adding limine support instead of just rewriting it whole

later probably as well

i wanna rename nullium to something ngl

maybe something like deep blue (the ibm chess super computer) except not even copyright issues its just somewhat generic?

[wild glen]

32 powerpc's

32 powerpc's yet it still cant run google chrome

[hushed briar]

I had the idea of the name deep purpose once

[wild glen]

well mine doesnt exactly have a purpose

so i can just make it blue as fuck

[hushed briar]

I like the idea of the name Blue infinity or something like that

[wild glen]

maybe idk

[hushed briar]

I’ve been kinda wanting to name a kernel soemthing infinity for a long time

[wild glen]

i named mine popkernel which is a ridiculously stupid name but it works

guys i deletbed by ps2 driver

no moar pee s 2

https://tenor.com/view/reverse-evaporate-condense-emoji-cry-gif-15922557730544177202

time to not bullshit about "bruh the drivers are in userspace"

why did that separate

WHY DID THAT SEPARATE DISCORD BRUHHHHHHHHHHH

they ruined the funny now im sounding like "phase 2 edgy roblox kid bossfight"

anyways uh

doorknob

no more ps/2 driver thats gonna go into the user space now tldr

when that will appear

sometime

(never?)

[wild glen]

what 2 do if lower mapped kernel (someone will murder me for this)

it was always lower mapped anyways

will this affect porting software tho

i def have to recompile it thats a no brainer but in any other way

the linker file would need like an offset thing of 512 mb if i give 512 to kernel

[wild glen]

video game idea
your only weapon is a cannonball launcher and maybe a throwable bomb

but you can do insane ass combos with both of them

throw a bomb at the cannonball to do a big boom boom

[wild glen]

uhh more vmm wheb i get home

i hate phone keyboards

how are people using phones without going insane its miserable without a proper keyboard

the only good-ish phone keyboard i used was the windows phone/win10m keyboard

rip winphone

it died before it couldve been enshittified

[hushed briar]

Just don’t

[hushed briar]

It will make it impossible most likely

[wild glen]

dangit

[wild glen]

how do i map it in there tho

do i have to set it up in the entry file?

[hushed briar]

Just don’t

[wild glen]

don't what

lower half kernel?
no
how to do higher half kernel?
no

wait

ok nvm i realized

the "just don't" still doesnt make any sense but i think i figured out how

[hushed briar]

I was saying don’t map in lower half

[wild glen]

oh

i mean it was already mapped in the lower half

[hushed briar]

Wait sorry

I thought you meant

Map your kernel in

Physical low memory

I was like wtf

[wild glen]

i mean the kernel is in physical low memory

by higher half i meant virtual high memory

[wild glen]

nvm

i in fact do not know how to map it in the higher half

[wild glen]

guys

github has wikis

yooooooooooooooooo

[gloomy musk]

you're just now finding this out?

[wild glen]

yes sadly

https://tenor.com/view/patrick-patrick-star-patrick-bottle-gif-6605208024845857705

this is literally me

i swear

i can put the documentation on there tho

when the time comes

[wild glen]

can everything be as easy as writing a hello world os

actually no

can i not be a fucking 400% dumbass distracted by everything

LITERALLY everything

multitasking is a war crime

it's absolutely necessary but i feel like it ruined me

[hushed briar]

Just work on one subsystem at a time

[wild glen]

no i mean like i get distracted by like the internet

[hushed briar]

All of do brotha

[gloomy musk]

Unplug your router

very relatable tho

[hushed briar]

If it makes you feel better, my friend was so down bad he bailed a random girl he thought was hot in jail and ended up getting with her. Talk about a gamble

[wild glen]

What

how the fuck do you bail a random dude person out of jail

[hushed briar]

You look at mugshots

All jails have a record of their inmates online

[wild glen]

no no i know

how do you just get them OUT of it

[hushed briar]

Go to the jail

Pay their bond

Boom

[wild glen]

oh

how much money did that guy pay

[hushed briar]

Yeah he was down atrocious

[hushed briar]

Like 4k 💀

[wild glen]

what happened to him afterwards

[hushed briar]

They’re still together

[wild glen]

thousands of dollars for some random imprisoned bitch is beyond normalities

[wild glen]

[hushed briar]

I’m just a bit afraid he might get murdered in his sleep

I mean she’s cute sure

Like pretty cute but

Not 4k and potential death pretty

[wild glen]

he had priorities

questionable ones but priorities

[hushed briar]

Nah he’s a gooner

Really bad

Like

Neck beard

All the shit

[wild glen]

oh god

reddit user?

no but srs i feel like if he's all that crap then i feel like the girl is with him because bro paid 4000 fucking dollars

[gloomy musk]

wooot

[wild glen]

a indeed

[hushed briar]

I mean he did lock in and she kinda made him have a glow up

He went from a 4/10

To like a 7/10

[wild glen]

nice

[hushed briar]

They’re actually surprisingly good together but I always make fun of him because that is Down badddd

[wild glen]

that aint worth 4000 dollars tho thats just worth a motivation

[wild glen]

oof

[hushed briar]

She didn’t commit like murder. She was in there for tax evasion

[wild glen]

for how long are they together

[hushed briar]

Not the worst crime in the world lmao

[wild glen]

based

[hushed briar]

Almost a year now

About as long as me and my current girlfriend have been

[wild glen]

cool

absolute ass opinion but for some reason loving people romantically is boring asf

[gloomy musk]

huh 😆

[wild glen]

idk man

how are you this desperate for some random ass human being

how could anyone be this desperate deadass

[gloomy musk]

true tho XD

[wild glen]

maybe i havent found anyone i like yet but still though

the disappointment i have for some people is insane

[hushed briar]

Whattt

I am so desperate for my girlfriend bro

We literally almost died together

We went to a party and we got laced

With some really bad drug

Like bro she is my ride or die

[hushed briar]

How else am I supposed to love someone

I love that girl more than life itself

[gloomy musk]

now see, this is why I don't go to parties (I say but the real reason is I'm homeschooled and don't get invited to any parties lol)

[hushed briar]

In the guy on the right

She’s the girl next to me

[wild glen]

welcome random ass image to the nullium thread 🔥

(joke)

[hushed briar]

My bad lol

[wild glen]

nah its fine

to whoever's gonna be scrolling up 50 years later

that aint me im too lonely /hj

[wild glen]

nice tho

[gloomy musk]

coolio :3

[hushed briar]

You are not old enough lmao

You’re 15 iirc

[gloomy musk]

I'm not anyhow ye lol

16

[hushed briar]

Yeah

I started going to parties at that age unfortunately

[gloomy musk]

🥀

[hushed briar]

I partied alone at the age of 13 tho

Stole my parents liquor 🤣

Good times

[wild glen]

birthday parties

drink apple juice say it's "beer"

makes you look cool

+5000 style stat

i have noise cancelling headphones now they solved my fear of lightning bolts and shit

[wild glen]

[hushed briar]

Actually scratch that

I snuck into a college party at 15

With My “friend”

[wild glen]

college party

[hushed briar]

Yeah

[wild glen]

with your friend

[hushed briar]

Fucked my life up xD

Not my friend anymore

He tried to get me to do much harder shit

[wild glen]

oh

[hushed briar]

Fuck all that

[wild glen]

drugs evil

dont smoke kids

[gloomy musk]

I'd rather use my shinobi sneaking skills for something else lol

[wild glen]

https://tenor.com/view/stop-it-get-some-help-gif-15058124

[hushed briar]

Oh definitely smoke (if you do already but don’t start if you haven’t) but don’t do drugs

[wild glen]

iphone 49 pro max

[hushed briar]

Weed made me quit everything

[wild glen]

sad

addictions are brutal

[hushed briar]

Yeah I unfortunately have an extremely addictive personality

Yeah I’ve been to rehab 4 times

[wild glen]

[hushed briar]

Damn that sounds worse saying it than thinking it

I went once when I was 16, twice when I was 17, and once while I was 18

I’m sober off all drugs but weed tho :)

Have been for months

I’m almost a month sober from alcohol

First time since I was 15

[wild glen]

i remember hearing college parties are deranged as shit

not just deranged like absolutely uber fucked

microwave popcorn banger

its supposed to be shit because microwave but its a banger

[hushed briar]

Yeah… they are

There was one time I was at one

And they found out I was lying about my age

And they said I had to drink a whole ass 12 pack of beers to stay

And unfortunately I did

[wild glen]

12 beers

i cant even drink a single pepsi can sometimes

jesus christ

[hushed briar]

Pepsi is gas

[wild glen]

true

heard that coca cola was invented before refrigeration and pepsi was invented after so warm coke tastes the same as cold pepsi

or smth

idk i want to test that

[hushed briar]

Coca Cola contained cocaine at the beginning

[wild glen]

i do know

[gloomy musk]

wait fr?

[hushed briar]

Yes

[wild glen]

they put fucking radium in toothpaste back then

coca cola having drugs is probably the most chill thing

[hushed briar]

People took this medication called Radithor

Which had radium

And some guys JAW FELL OFF

[wild glen]

guy drank it and his jaw fell off?

[hushed briar]

FROM IT

YES

[wild glen]

guessed it

famous story

[gloomy musk]

bloody hell

[wild glen]

nullium and floppaos thread all being gatherings for random bullshit is certainly a thing of all time

[wild glen]

yes indeed

i think the girl who discovered radium died from radiation poisoning or smth

marie curie

[hushed briar]

Yessirrrr

[wild glen]

literally anything else is a normal progress thread while these two have a randomized schedule of being #lounge-2 and #osdev-misc-2 (was an actual channel somehow???)

ima check out the progress threads maybe people make something that sucks less ass

ok im back

my project total doodoo farts compared to these absolute gods im now evil

[hushed briar]

My project doodoo farts compared to the gods too

[wild glen]

they got qemu on their os's

[gloomy musk]

mine as well lol

[wild glen]

i wanna run qemu tho ngl

would be worth it

[hushed briar]

You just need to implement the syscalls it requires

[gloomy musk]

to this. I don't have QEMU in my OS 🤣

[hushed briar]

Idk how many syscalls it requires

If you wanna do something like KVM, good luck

[gloomy musk]

KVM sounds painful

[hushed briar]

Not even remotely reachable for the majority of hobby OS’s

[wild glen]

kernel vm's?

oh hell no

[hushed briar]

KVM is a Linux thing but yes it means kernel virtual machine

It runs the kernel as a hypervisor

Or to function as a hypervisor

[wild glen]

why are sgi workstations so cool
idk i remembered the indigo line when i made that color palette for my terminal

[wild glen]

nice

[wild glen]

progress report (finally ffs):

• added two functions
• map physical address to virtual address
• do the same but in bulk (you can remap an entire page table for example)

mmmmm

vm&m's

[wild glen]

reworking the second function

reworked function for easier use for me

second one

mapping physical addr is fine

mapping a shit ton of them wasnt

until now

[hushed briar]

NICE BRO

LETS GOOO

NULLIUM PILLED

[wild glen]

what does pilled mean

[wild glen]

average linux user vs chad nullium user

[wild glen]

does anyone else tho not want their os to get mainstream famous

like linux

bcs the script kiddies would come in, say they're cool because they can put fucking poopOS on a usb and run it on a computer

(they cant actually install the os because they cant navigate the hard drive partitioner)

like actually

theyll also not know literally anything about osdev and will crash out that you cant run fortnite

or any windows apps

"why cant i run google chrome" ;-;

telling them what porting is theyll just go "well just build it for your os its easy"

[balmy stump]

an os we make will never get maisntream famous unless its one of the few that has like tens of contributors

[wild glen]

chromium WAS ported to a few project but still

[wild glen]

fair

[balmy stump]

and even then mainstream would be pushing it

[wild glen]

[wild glen]

nullium is being delayed several thousand years i have to do a spanish coloring assignment 😭

[wild glen]

nullium is getting delayed 100 years instead because i did the assignment

i need an excuse to never release version 1.0

[wild glen]

new somewhat bright-ish purple palette

if the color is literal cancer plz tell me i think its fine

discord for some reason makes the image more saturated?

[gloomy musk]

looks fine to me 👍

[wild glen]

mk

two vmm's

[gloomy musk]

the more the merrier

[wild glen]

i need a slab allocator or something like that now

darker colors look like ass

brighter colors slightly modified

idk what to do with magenta

it looks way too saturated

customizable color palettes are a necessity probably

what if some dude just wants his plain old boring ass VGA

(though id be offended because i took an unnecessary 20 minutes to make these stupid fucking color palettes)

(i wanted one though so whatever)

i like them

or something

anyways the purple does sadly indeed look like cancer

so ima tone it down

i think the vmm init is ok

anyways rate color palette ima do something somewhat useful

[hushed briar]

Idk if it’s cancer it’s just kinda

Different

[wild glen]

the purple part is now much more noticeable tho

it was always purple but it was this specific shade where you can barely see it

for some reason discord fucked up the colors

its bright on it

on qemu its way less saturated

i should test my thing on real hardware ngl

[wild glen]

yo any serial terminal people here
how do i use it with gdb im stupid

oh

nvm i have to implement a stub or something

[wild glen]

guys i feel funny so ima run nullium on real hardware

there is nothing to run but shush im bored

its ✨ scientific ✨

my testing laptop :P

also the reason im still in protected mode

it looks too cool to just abandon

$75 thinkpad my beloved

anyways since now this laptop is basically the main one if im testing on real hw

i should setup a PXE server for it ngl

giddity init ok

[gloomy musk]

ayyy! 🎉

[wild glen]

im pretty sure grub / limine (no other bootloaders exist ever) have a tag for setting a custom framebuffer screen resolution on boot

like for mb2

and i demand to know where in the fuck are the instructions for limine

i found out how to do it for grub but how do i do the same for limine

https://codeberg.org/Limine/Limine/src/branch/v9.x/CONFIG.md

ahem

y not in readme.md this locate in readme.md need to be

hyperlink from readme.md to config.md be locate must now

:C

resolution - The resolution to be used should the executable request a graphical framebuffer. This setting takes the form of <width>x<height>x<bpp> and overrides any resolution requested by the executable. If the resolution is not available, Limine will pick another one automatically. Omitting <bpp> will default to 32.

it is time to try this goober

the tag works

all hail funny purple L bootloader

gnu website dead

Many modern operating system kernels, such as Mach and the microkernel in VSTa, do not by themselves contain enough mechanism to get the system fully operational: they require the presence of additional software modules at boot time in order to access devices, mount file systems, etc.

GNU mb2 spec

popkernel as a microkernel isnt dead lets goooo

if limine boot protocol doesnt have modules then i can claim superiority over the unix likes

[wild glen]

boot args

[wild glen]

syntax idea for the shell that will later exist

parameters start with . or : if its a long ver of a parameter
like verbose mode would be like .v but if its multiple letters itll be :verbose
if a thing is a parameter itll just accept parameters in parentheses or smth :flags(verbose,debug) (maybe square brackets?)

idk why they dont start with -- and - like normal os's 😭

ideas (TM)

also what if i move to codeberg

[rocky elbow]

I don't know, I don't see any difference between codeberg and github except for the interface

[wild glen]

idk github is like microsoft managed and ai feeds off of public code
doesnt really matter i doubt its worth the effort

[hushed briar]

I actually kinda like that

[wild glen]

thanks

idk how running programs would look like

[hushed briar]

run <program>

That’s what I’m doing

Or ex <program>

[wild glen]

smth like nano would be ./nano, nano, or PROG(./nano) or smth

[hushed briar]

The parenthesis are ehhhh

[wild glen]

idk how commands would look like

[hushed briar]

It’s not intuitive

[wild glen]

nano(text.txt)??? idfk

[wild glen]

fair

i got the flags ok enough but what would the commands look like idk

smth like cd /evilAssFolder/ would be the simplest

[hushed briar]

Yeah

That’s how mine will be

[wild glen]

idk about having like cd(/evilAssFolder/)

[hushed briar]

That isn’t shell like tho

[wild glen]

true ig

[hushed briar]

I mean it’s your thing but just from the way I see it

I think I’ll execute programs with

Either run, ex, or load

[wild glen]

cd:/evilAssFolder/

[hushed briar]

Oh god

That is just cursed

[wild glen]

lemme grab some shit from my make file and see how it would look best in my stupid fart syntax

gcc -c ./popkrnl/boot/stage1/stage1.c -o ../popkrnl/kernel/stage1.o

removed all the variable stuffs

[hushed briar]

Yeah

That’s nice

More shell like

[wild glen]

in theory itd just look like this gcc .c ./popkrnl/boot/stage1/stage1.c .o ../popkrnl/kernel/stage1.o

[wild glen]

no thats the linux command

[wild glen]

what to do with smth like this

itd think its a flag or smth

[hushed briar]

I like it

[wild glen]

put them in quotes idfk? gcc .c "./popkrnl/boot/stage1/stage1.c" .o "../popkrnl/kernel/stage1.o"

[wild glen]

fair

[wild glen]

wait

[hushed briar]

The quotes are a bit much

In my opinion

[wild glen]

if a thing is a parameter itll just accept parameters in parentheses or smth :flags(verbose,debug)

gcc .c(./popkrnl/boot/stage1/stage1.c) .o(../popkrnl/kernel/stage1.o)

damn

this looks like some c dialect

im fine with it but idk

[hushed briar]

Maybe you should use something else to suggest the pwd if you’re gonna use . for flags

[wild glen]

ok cd is just gonna be smth like cd ./johnDoor/ it's the same in dos, linux, unix, pooix, etc

[wild glen]

idk

everyone uses "."

[hushed briar]

Yeah

[wild glen]

you cant have a flag inside a flag probably

current dir could be > and upper dir can be ^ idk

or <

everyone uses . and .. so i dont really want to break the unspoken rule

have a specialized (easy to type?) folder tag maybe

cd @./potato/

add a @

[hushed briar]

I like the @

I’ve been considering something similar actually

[wild glen]

gcc .c(@./popkrnl/boot/stage1/stage1.c) .o(@../popkrnl/kernel/stage1.o)

[hushed briar]

Referring to all paths with @

[wild glen]

m

[hushed briar]

I feel like there’s just a bunch of unnecessary parenthesis

It doesn’t help readability

[wild glen]

variables can be like %VAR% or %[VAR]

[wild glen]

does it ruin it?

if not then i think it's better for the interpreter actually it's easier to read something like that

if it found like a flag then just check for a parenthesis and start looking inside there

dos had an ungodly version of this

dir /A:DRH for example

or was it dir /A:D,R,H

(also that command looks for hidden read only directories)

(theoretically)

(i cant just pull up windows 98 out of my ass)
