[frozen lantern]

why?

[pulsar prawn]

i hate gdt

dont mess that up

[frozen lantern]

you have wayy too many entries

[pulsar prawn]

found that from a random repo

[frozen lantern]

BRUH

[pulsar prawn]

(My gdt pfed on ahci)

the only solution

even it has too much or too little enties

[frozen lantern]

well, you have to set the entries correctly

[pulsar prawn]

(i dont wanna clear the junk up)

even thouch im tryna be a big O developer

[frozen lantern]

also, why cli here?

[pulsar prawn]

after 4 months of fighting gpt with ahci

[pulsar prawn]

for some reason, mr limine decided to enable interrupts earlt

[frozen lantern]

wtf

[pulsar prawn]

thats why remap_pic pf

[frozen lantern]

also, pls tell me you're not using sse in kernel

[pulsar prawn]

or rebooted randomly

[pulsar prawn]

im using it

[frozen lantern]

oh god

[pulsar prawn]

my pc doesnt have avx tech sorry

[frozen lantern]

you shouldn't use sse / avx / floating in kernel...

[pulsar prawn]

printf needs it

[frozen lantern]

no

it doesn't

[pulsar prawn]

yea

[frozen lantern]

nope

[pulsar prawn]

• i want float

[frozen lantern]

you can "simulate" floats

[pulsar prawn]

see: https://github.com/mpaland/printf

[frozen lantern]

yeah, you can disable sse

or well floats

[pulsar prawn]

but now, i need them(at this stage)

[frozen lantern]

why?

[pulsar prawn]

idk, one thime,i enabled it + disabled sse. Then out of nowhere

it pfed at a random address

like

0x00000

[frozen lantern]

yeah, well, maybe go check that problem...

enabling sse is prob the worst choice

[pulsar prawn]

why?

i wanna know

[frozen lantern]

it can cause a lot of problems

if not handled properly

[pulsar prawn]

can it cause my fat32 driver not resolve paths properly unless cd into tht directory

[frozen lantern]

well, threads can use sse

also @pulsar prawn why?

why an array

[pulsar prawn]

fs is not stable yet

[frozen lantern]

wdym

what does fs have to do with this?

a linked list would prob work better here

so you are not limited and are not wasting space

[pulsar prawn]

Oh linked

list

thank you very much

ill note it

completely forgot about it lol

[frozen lantern]

i have an implementation in my os if you want

[pulsar prawn]

ok

ill see

[frozen lantern]

https://github.com/Diamantino-Op/HorizonOS/blob/main/src/libs/hos-base/src/LinkedList.hpp

[pulsar prawn]

Why microsoft(also, i cannot use linux cuz my dad cannot use his favourite spreadsheet, Excel, he hates Excel on the website, but,he likes the local version)

[frozen lantern]

dual boot

• windows vm just in case

[pulsar prawn]

(He knows whats dual boot)

also

vm...

ill think of that

[frozen lantern]

try WinBoat

[pulsar prawn]

ok

[frozen lantern]

also @pulsar prawn you are doing sse wrong in your kernel

it won't work like this

you are not doing fxsave / xsave, fxstor / xstor

[pulsar prawn]

Tasks:

1. Fix sse
2. Add Data Structures like Linked Lists, Priority queue

[frozen lantern]

so in this case you cannot use sse or well, floating point in general in threads

and i would suggest you add lapic / hpet

lapic for scheduling

and hpet for sleep

[pulsar prawn]

i just cannot bear the interrupts so

id rather a/c pull rqsts

[frozen lantern]

huh?

[pulsar prawn]

i think lapic and hpet calls interrupts

[frozen lantern]

yes

[pulsar prawn]

is just purely my skill issue

also

[frozen lantern]

bruh

using pit is so bad

[pulsar prawn]

itll be hell in the future

[frozen lantern]

yes

especially bc PIT is very low resolution and not good at all

[pulsar prawn]

this is why im beggin for pr

[nova dome]

you shouldn't be using sse in the kernel unless you 1. have a really good reason for it or 2. you allow it in kernel tasks that fxsave/fxstor on entry

[pulsar prawn]

1. Really bad reason

printf

• i want float so baad

[nova dome]

you should have almost 0 reasons to use floats in the kernel at all

[pulsar prawn]

future program

[nova dome]

unless they are in tasks

[pulsar prawn]

also

[nova dome]

that should be in userspace

not in kernel mode

[pulsar prawn]

i wanna fix fat32

[nova dome]

huge difference

[pulsar prawn]

and lapic

and pit and timer systems first

[pulsar prawn]

float Q_sqrt(float number) {
    long i;
    float x2, y;
    const float threehalfs = 1.5F;

    x2 = number * 0.5F;
    y  = number;

    i  = *(long *)&y;
    i  = 0x5f3759df - (i >> 1);
    y  = *(float *)&i;

    y  = y * (threehalfs - (x2 * y * y));
    y = y * (threehalfs - (x2 * y * y)); // 2nd iteration
    y = y * (threehalfs - (x2 * y * y)); // 3rd iteration

    return number * y;  
}```

I think why i need it now

[wicked palm]

Why do you need sqrt

[nova dome]

again there are few places where floats are useful in kernel mode

[pulsar prawn]

idc,but its cool

also

note that userbase+multitasking is just a stunt to test my paging system

nothing else 😄

[pulsar prawn]

also, nwe kernel panic screen:

[pulsar prawn]

me be like when i enable sse

[true flower]

you dont need it man

[pulsar prawn]

well, another side on telegram tells me i need it

whom should i choose!

[true flower]

the server that specializes in fricking os development, maybe???

[pulsar prawn]

there is also an server where douglas is there

in telegram

for osdever

[true flower]

who tf is douglas

https://tenor.com/view/tenna-mr-tenna-ant-tenna-glooby-deltarune-gif-2362686432571745081

[pulsar prawn]

his malloc impl

is W

(im planning to use it after kernel is stable with a kalashinkov)

[true flower]

do you have a pmm and vmm yet?

or at least the pmm

[pulsar prawn]

pmm(k_malloc)+vmm(malloc)

fat32 who works with ata + ahci

who has lfn support

who is boss at directory cding

but struggles to create files in a directory unless cded into it

[true flower]

not

[pulsar prawn]

but struggles to read files from a dir unless cded into it

[true flower]

neither of them are mallocs

[pulsar prawn]

then how theck i impl ahci

did osdever.net tricked me again

but

it works

[true flower]

all tutorials are evil

[pulsar prawn]

(verified with hexdump)

[true flower]

theyre heresy to the osdev gods

[pulsar prawn]

mintsuki sir why did u have to rename everything

[pulsar prawn]

just like limine docs

but ngl

GNU GRUB is L

limine is W

W

[true flower]

limine docs arent a tutorial

[pulsar prawn]

that what i understood

[true flower]

90% chance you use gcc

[pulsar prawn]

yes

but

grub is L

W limine

[true flower]

90% chance you use grub on your pc

[pulsar prawn]

nein

i use limine(r)

in windows

[frozen lantern]

still need to fix sse in threads

[pulsar prawn]

theads are just a knockoff simulation

to ragequit test my paging system

[pulsar prawn]

bro,u changed ur name so quickly

bruh

GNU = donke is not unix

only useful product is gcc and linux

[nova dome]

ah yes the widely known gnu product linux

also ignoring all of gnu core utils

and binutils ig

[pulsar prawn]

banutins

monkeutils

2 hours compiler compiling

[nova dome]

that doesn't make them not useful? they were the default on linux for years

and they still are the default for most distros

[pulsar prawn]

r u an idiot?

i was an idiot

to compile my compiler for osdev

after listening to osdev wiki

but

mintsuki limine

template said hell nah

lets use the builtin cc

[true flower]

https://tenor.com/view/wobble-pensive-emoji-pensive-ish-wobblepensive-gif-26167268

dudeWhat

[nova dome]

yeah you can do that as long as you are on the same platform you are compiling for

(or just download clang and use it's targets <3)

[true flower]

or just download gcc for your os from some package manager idk

arch aur

mac homebrew

idk

[pulsar prawn]

i like mintsui

anyways

windows just randomly updated himself from win 10 to win 11

why??

[true flower]

because its microsoft

[pulsar prawn]

microsoftware nonsense be like

[signal yew]

my eyes spotted a kernel shell 😭

[pulsar prawn]

yea yea

i luv shell

[signal yew]

We don't like kernel shells in this server, put it in userspace instead :D

[pulsar prawn]

ugh

[pulsar prawn]

yes thats what imma do

[true flower]

lazy people moment

[pulsar prawn]

shut up @true flower

Formal talk only

[nova dome]

"why hate kernelspace" > tradition

yeah sure

I prefer my browser to not crash my whole system if it crashes

I also like it not being able to access everything on my system

including all of the hardware

[pulsar prawn]

well

i just learned

why u hate kernelspace

and im migrating to userspace amerika

[nova dome]

I don't hate kernelspace

it's just not the right place for user programs

hence the name userspace

[pulsar prawn]

y

also

which libc

i need proof that it's lightweight

[nova dome]

prob mlibc

[pulsar prawn]

and pipable

[pulsar prawn]

musl

more like mussolini

💀💀

[nova dome]

what?

[pulsar prawn]

anyways

stupid joke

[nova dome]

formal talk only btw

[pulsar prawn]

ok

also

im a proud 4+4 gib = 8 gib ram owner

imma limit doorsos to 32kib for editin

[tulip garnet]

what

[pulsar prawn]

ANNOUNCEMENT FROM DOORSOS COMMUNITY

Since DoorsOS' 50% ownership has gone to Corex Corporation in Germany. The developer is working to go to highlevel and userspace as soon as possible. Thus, choosing an proper libc is required, also,it is required to be lightweight. Please discuss and give me the best answer.

[tulip garnet]

I cant tell whether this is satire, trolling, ragebaiting, or you are 11

[pulsar prawn]

im 13

[tulip garnet]

I think ill pick option E. all of the above

bruh

i aint ragebating

its my brain in chill+formal mode

[tulip garnet]

presumptious of you to claim you have braincells

[pulsar prawn]

WAIT, u OWN NIXOS

[tulip garnet]

no?

nobody does?

[pulsar prawn]

and Elysum os

?

[tulip garnet]

no

not and

[pulsar prawn]

hi

[ionic raptor]

Heyyy! 👋

[pulsar prawn]

hey

[pulsar prawn]

hi

hallo

@simple wolf discuss here

[simple wolf]

all I am saying is that uacpi shutdown in barebones is impossible

[pulsar prawn]

its possible

[simple wolf]

no not really

[pulsar prawn]

yes

[simple wolf]

I know how uacpi work

[pulsar prawn]

not really

u need to

get the

facp values

and

[simple wolf]

you need to evaluate

pts

and _S5

with AML

[pulsar prawn]

run the "<<"thingy

well

limine does it

[simple wolf]

or you could try to write bullshit data to that port and hope it works

[pulsar prawn]

yea,that it how i did honestly

but using the data

from facp

/poll is HPET worth a ty

[simple wolf]

the FACP table only contains the ports to write to

[pulsar prawn]

yes

[simple wolf]

not the values you need to write

[pulsar prawn]

i need the ports thats it

[simple wolf]

and most hardware needs evaluation of the _PTS object for everything to shutdown properly

[pulsar prawn]

well

ill switch to aml

after that damn multitasking works

[simple wolf]

and writing BS data on a port is a really bad idea on any real hardware too

as you cant just guess what values you need to write

[pulsar prawn]

true

but for now

qemu only

(LOOKS LIKE QEMU COPY-PASTED BOCHS THINGS I SEE FROM THE LOGS 🤣 )

[pulsar prawn]

hi
