[spare quartz]

also found a bug with string conjunction

beyond 15 chars* a GPF is thrown

[timid quartz]

lol

ur violating the general protection of your system

[spare quartz]

it's probably an issue with memcpy again

[timid quartz]

but then if you just ignore the interrupt

one simple trick OS designers don’t want you to know

[spare quartz]

yeah i tried adding a basic IVT

it didnt' work

it just threw a gpf while trying to write to 0x0

i'll just defer that to protected mode and use an IDT

[timid quartz]

Gotta be in ring zero silly

[spare quartz]

what do you think real mode is 😭

[timid quartz]

[spare quartz]

also technically since im memcpying acpi i can overwrite that data without any issues

the issue is its in the BDA or EBDA (both of which could do bad things since SMM also uses that memory)

hm,mm

im not very well versed in allocator design so

would a compacting gc > a fragmented linked list

[timid quartz]

.section .text
.globl _memcpy

# void *memcpy(void *dest, const void *src, size_t n)
_memcpy:
    pushl %ebp
    movl %esp, %ebp
    pushl %esi
    pushl %edi

    # Load the arguments
    movl 8(%ebp), %edi  # dest
    movl 12(%ebp), %esi # src
    movl 16(%ebp), %ecx # n

    # Copy the bytes
    rep movsb

    # Restore the registers and return
    popl %edi
    popl %esi
    popl %ebp
    ret

memcpy

[spare quartz]

function Copy_Bytes
      (To, From : Address;
       Length   : Integer_Address)
   return Address is
      From_Chunk : Chunk (1 .. Length) with Address => From;
      To_Chunk   : Chunk (1 .. Length) with Address => To;
   begin
      for Index in 1 .. Length loop
         To_Chunk (Index) := From_Chunk (Index);
      end loop;
      return To;
   end Copy_Bytes;

i could probably do To_Chunk (1..Length) := From_Chunk (...)

[timid quartz]

use std::arch::asm;

pub unsafe fn memcpy(dest: *mut u8, src: *const u8, n: usize) -> *mut u8 {
    let mut edi: *mut u8 = dest;
    let mut esi: *const u8 = src;
    let mut ecx: usize = n;

    asm!(
        "rep movsb",
        inout("edi") edi => _,
        in("esi") esi,
        in("ecx") ecx,
        options(nostack, preserves_flags)
    );

    dest
}

(idk if this will work, blame claude ai)

[timid quartz]

memmove

[spare quartz]

well gotta write a new function where i have to guess the signature

[timid quartz]

wdym guess the signature

does ada mangle signatures?

[spare quartz]

no but theres a possibility of it being defined by gnat over c

[timid quartz]

yall need #[no_mangle] fr

[spare quartz]

we don't mangle functions

[spare quartz]

let me try void *memmove(void *dest, const void *src, size_t n)

would probably be prefixed like __gnat_ though

[timid quartz]

why do you even have to do that

[spare quartz]

wdym

[timid quartz]

like why are you having to guess these functions

[spare quartz]

they're internal functions

[timid quartz]

ok but you're literally writing a kernel

[spare quartz]

yeah but the alternative is reading GCC source code

[timid quartz]

the alternative is write some assembly no?

[spare quartz]

💀

[timid quartz]

cause you're not linking to any libraries

[spare quartz]

i hate assembly!!!!!!!!!!!!!!!!

[timid quartz]

get ai to do it for you...

[spare quartz]

ew

[timid quartz]

or just like idk

[spare quartz]

the rtl is technically a library but im also writing that

[timid quartz]

write a function in ada that works...

[spare quartz]

hmm

i wonder if i can just define it as a compiler intrrinsic

[timid quartz]

me when I define you as a compiler intrinsic

[spare quartz]

okay memmove works

lemem go read the x86 manual real quick

[timid quartz]

oooo x86 assembly 👻

at&t syntax 👻

[spare quartz]

gcc inline asm uses at&t by default yes

can actually just use my new functions for out/in since those are inlined

hey guys..

what do you think of my revolutionary npm package

https://www.npmjs.com/package/astros-first-package

i didnt see any other package that does this

[spare quartz]

could try an optimization likw movsd and div length by 4 but

[full berry]

sooooo

[spare quartz]

might not outweigh the gains

[spare quartz]

package name looks like a virus

thread locked

okay

reading the bayachao wiki was a mistake

i'm using a stupidly low power rtansmitter for it though

im dealing with RF that can be blocked by my hair 😭

[spare quartz]

alright

i purified my entire RTS

[pastel tinsel]

crazy

[spare quartz]

everything that can be Pure is Pure, everything that can't is Preelaborate, or at least, No_Elaboration_Code_All

Pure                      : Package has no side-effects
Preelaborate              : Package will not execute code at elaboration time
No_Elaboration_Code(_All) : No package elaboration code will be generated

https://fixupx.com/samsja19/status/1883662518318727245

i can do that???

*A special case recognized by the compiler is the specification of a Storage_Size of zero for an access type. This means that no items can be allocated from the pool, and this is recognized at compile time, and all the overhead normally associated with maintaining a fixed size storage pool is eliminated. *

https://fixupx.com/mitsuhiko/status/1883909722039820604

[spare quartz]

hmm

i could probably get away without allocators by doing this

not sure how though, like casting an Address to an access?

this ada stuff is complex

[lavish dove]

llama 3.2

I have a rtx 2050 and it generates nearly instantaneously

for some reason ollama uses like 200 megabytes of ram so I keep having t oturn it off when im not using it

and it doesnt work if I use it when its not on through systemctl

[spare quartz]

holy crap it works

unironically really cool

[spare quartz]

i think this is roughly equivlent to casting a C void* pointer to x*

well okay

kinda

Address -> PC -> Ptr is more like casting an int to x*

got them into a discriminated enum

which meannnnnsss

i can make it a variant record! without any heap allocations!

memcmp

[lavish dove]

I hate debugging asm

[spare quartz]

IT WORKS

[lavish dove]

nice

[lavish dove]

rep memcmp meanwhile (its slow asf)

why tf does intel let instructions get slow

why do they make instructions that are slow

[spare quartz]

i read that with movs too

apparently they let it get really slow but then sped it up again

[lavish dove]

theres also the loop instruction

[spare quartz]

now its fast* (a CPUID bit determines if its optimized or not)

[lavish dove]

its literally just cmp rdi, x jx y and its slower than actually doing cmp rdi, x

[lavish dove]

wow

I swear intel should make a fuckin

[spare quartz]

https://stackoverflow.com/a/43845229

[lavish dove]

super x86 mode where every instruction is fast asf

though theres less instructions

[spare quartz]

okay ARM

[lavish dove]

and all the old modes are firmware emulated

fr

[spare quartz]

even though ARM and x86 are roughly equal in complexity today...

[lavish dove]

bro they should make x86 more complex and faster

[spare quartz]

they should just give us microcode programming

[lavish dove]

true

lol

computers were fast before microcode!!! raah

super x86 mode isnt made with microcode so its very very fast fr fr

[spare quartz]

yeah well now there's like 500 different chips inside a bigger chip controlling what an instruction actually is

[lavish dove]

fuck modern computers

[spare quartz]

https://en.wikipedia.org/wiki/Control_unit#Hardwired_control_unit

this looks kinda like that

[lavish dove]

yea

it is that

thats how you make cpu's fr

all the old cpu's are made like that

instead of having a miccrocode or proccessing or shit they just run the instructions no extra complexity or anything

by old I mean like <1990 old

; eax = lba
; ecx = ammount of sectors
; edi = to
; converted to int 13h so accuracy is lost idk. uses tempsector and memcopies to
; trashes everything
.loopreadlba:
  pop eax
  inc eax
  dec ecx
readlba:
  push eax
  push edi
  push ecx
.h: hlt
  jmp .h
  mov ecx, 64
  div ecx
  mov cl, dl
  mov ch, al
  mov bx, 500h ; temporary storage
  mov al, 1

  xor dh, dh
  mov dl, byte [discsave]
  mov ah, 2h
  int 13h

  pop ecx
  pop edi
  mov ebx, 500h
.loopnxt:
  mov dl, byte [ebx]
  mov byte [edi], dl
  inc ebx
  inc edi
  cmp ebx, 0x700
  jne .loopnxt

  cmp ecx, 0
  jg readlba ; loop through every sector

  ret```

fuck me

the hlt loop is for debugging

.loopnxt is a memcopy

[spare quartz]

i just realized i just made println debugging first thing in my kernel 😭

still need 2 write a serial adapter

reading this tweet from my backburner

[lavish dove]

im not gonna bother with serial

im just gonna go straight to keyboard and amd integrated modesetting

(im gonna cry trying to write a diver for amd)

[spare quartz]

if you want to be super lazy just poll ps/2

[spare quartz]

The generated function returns a Result containing the field value as a String, or a Box<dyn std::error::Error> if an error occurs.

im not a rust user but

Box<dyn std::error::Error> doesn't sound right

[lavish dove]

lol

wait how does error handing work

does it set a flag or something

[spare quartz]

in what context

rust?

[lavish dove]

rust sure

like in assembly its popular to set carry flag for a error

[spare quartz]

uhh bascially a function that can error returns a container with an enum inside of it

which can either be "good" for your actual data or "bad" for the problem

[lavish dove]

dyamn

that sounds kinda slow

[spare quartz]

i'm sure it's as fast as the C style of it

[lavish dove]

slower than setting a flag lol

yea

how tf

did my fucking

code freeze

in the fucking bios

[spare quartz]

did you overwrite a part of bios data or something

[lavish dove]

I wrote to 500h

but that should be the bottom

of free memory

[spare quartz]

yeah looks good

weird

[lavish dove]

lmao we looking at the same website

[spare quartz]

yeah

[lavish dove]

I hate debugging assembly 😭

im gonna make my own fuckin language that will happily compile to 512 bytes I swear to god

[spare quartz]

wait i gotta check my linker script

i forgot where my kernel is

oh

[lavish dove]

lmao

well thats 16 bit space

[spare quartz]

wait

iiii need to update my malloc function

it's gonna overwrite the kernel

ill just set the heap addr to 00000500

surprised 'Valid works this well without a stdlib

[timid quartz]

200mb is nothing

But duly noted

[spare quartz]

aagghh

discriminant in constraint must appear alone my behated

i don't like this but it has to be done

nice

now i gotta write it for 64 bit!!!

neat

got a full console

this marks ACPI reading complete

since this is really all i need

[spare quartz]

alright

added conole scrolling since the page scroll loses too much data

[timid quartz]

store all the lines in a file

[spare quartz]

there is no filesystem yet

[timid quartz]

breadfs

oooh call it gluten

[spare quartz]

already have a spec for that actually

[timid quartz]

cause gluten is the structure of bread

[spare quartz]

i imagine it won't be very performant though

since it relys on expansiveness

e.g. file metadata starts out using ints, but if higher precision is required, longs, long longs, big ints...

a LOT of our stuff relys on expansiveness actually

we just really like infinite precision

[lavish dove]

its alot for me 😭

[spare quartz]

this but programming

anyone feel me

hm,mm

i wanna add sound actualyl

[lavish dove]

yay

[spare quartz]

Channel 1 is unusable, and may not even exist.

[lavish dove]

bruh

my thing isnt even reading

any data

why

oh its giving me an error

nice

the error code is one

bruh

INVALID COMMAND

WHAT!?!?

it all looks perfect 😭

[timid quartz]

I downloaded ollama and ran llama3.2 w/ 3b tokens

honestly neat

fairly snappy

500mb ram

[lavish dove]

I think I got a higher one

[timid quartz]

2060 super so the util jumped to like 85% mid-response but still snappy

[lavish dove]

I wish llama was kinda better

and used opencl

it will only work if youve got a gpu with enough ram

it wont try any paging getup or shit

[timid quartz]

use uh deepseek ¯_(ツ)_/¯

[lavish dove]

and it straightup wont worko n anything that isnt cuda

[timid quartz]

https://ollama.com/library/deepseek-v3

[lavish dove]

no im talking about the tooll

not the model

llama3.2 is my favorite liek I told you 😭

[timid quartz]

ollama or llama3.2

[lavish dove]

ollama the tool

[spare quartz]

this is gonna be painful

[lavish dove]

oh dear lord

I have 2 pc's from 2012 and 2016 that have a real pc speaker

[spare quartz]

i have a pc speaker in mine rn

[timid quartz]

ah ic ic

[lavish dove]

and another one with pc speaker emulator

[spare quartz]

i bought a pack of 50 for like $3

[timid quartz]

well you could probably rawdog llama3.2 without ollama

if you wanted to use opencl

[lavish dove]

mine are inside the actual computers

no needed extra setup

[spare quartz]

ah

[lavish dove]

naw im too lazy

[timid quartz]

also deepseek-v3 is 404gb 😭

[spare quartz]

mine are just soldered to a header of 4

[timid quartz]

probably need 64gb ram minimum

for that

[lavish dove]

yeah tahts what im talking about with ram

[spare quartz]

ram or vram

[lavish dove]

you cant just get a fast ssd and have a fuck ton of ram

[timid quartz]

uhhh

probably ram

[lavish dove]

then throw cpu at the motherfucker

[timid quartz]

but probably need a lot of vram too

[lavish dove]

you haved to have enough ram to hold the entire model

[timid quartz]

ram or vram

[spare quartz]

just make an 800 gb page file

👍

[lavish dove]

yeah but ollama wont do that

:sob;

[timid quartz]

there's deepseek-v2 with 16b params

probably much lighter weight

[lavish dove]

man I want 128 gigabytes

[timid quartz]

ooh deepseek-r1 is also here

[lavish dove]

if its running on the gpu it wont work if you dont have enough vram on the gpu

[lavish dove]

and you cant switch between gpu and cpu

im gonna try deepseek

[timid quartz]

the 1.5b params is uh

1gb

[lavish dove]

allready downloading

💀

also the ollama servers are capped

[timid quartz]

wdym

ollama runs locally

[lavish dove]

the larger download the larger cap but its still a cap

[lavish dove]

to download a model

[timid quartz]

oh

wtf

[lavish dove]

look at it

download a big model

then see its suspiciously locked at a thing

like its a pretty generous cap but its a cap nonetheless

and this is all free open software they should just torrent it 💀

1.5b is kinda shit

I prompt it then it is still stuck on when I said hello 5 minutes

[timid quartz]

lol what mine is fine

[lavish dove]

😭

[timid quartz]

well ok

it responds

but

i tried asking it a logic question and it didn't do anything lol

like it said "this is out of my current capabilities"

[lavish dove]

lmao

[timid quartz]

but I asked it on the actual deepseek website

and it thought for a whole ass minute lol

could try the 7b model

[lavish dove]

wont run on my pc

I dont have enough ram

well im gonna try it and see if I was lying about the no paging thing earlier

omg my internet is slow 😭

ill see you in a few years

[spare quartz]

AHAHAHAH

IT WORKS

lemme rec

[lavish dove]

beeeep

my old computer is fuckin quiet

the emulated one is like 100 decibels

[lavish dove]

and the new one with beep is also pretty loud

[lavish dove]

now play music

[spare quartz]

i think i can

but i need to figure out how to read files first

im just gonna attach this to the printing functions

[lavish dove]

its working for me

[timid quartz]

neato

I'm gonna do the 8b based on llama

[spare quartz]

i really need to figure out how to impl IRQs without it causing a segfault

RTC is great but it only works on one vm platform and has a deadful 1000ms resoution

[lavish dove]

dam

[timid quartz]

91% util lmfao

[lavish dove]

yeah my gpu was going like

[lavish dove]

1 word half a secon

[timid quartz]

It's a little slower than llama3.2 3b but not very noticeably

[spare quartz]

does this count

[lavish dove]

yes

I love it

banger

bro has done all of this while im still working on a disc read function 😭

[spare quartz]

dw im catching up to that

[lavish dove]

well IT KEEPS GIVING ME AN ERROR

😭

im so mad at it

cuz im looking at the registers and everything looks perfect

oh nice its not erroing anymore

and its fucking stuck again 😭

what teh fuck did i do to get the error 😭

[spare quartz]

only one com channel and its already 50% of my entire low level pin enum

[lavish dove]

woah it actually wokrs the first few times yay

[lavish dove]

dyamn

[spare quartz]

end goal with this os ............... play a bayachao video

[lavish dove]

now im reverting to old versions and it doesnt work

[spare quartz]

neat

vmwares serial port is faulty but qemus isnt

[lavish dove]

WHY TEH FUCK

IS IT NOT WORKING

readlba:
  ; eax (lba) to ecx (chs) only cylinder and sector
  xor edx,edx
  mov ecx, 64
  div ecx
  mov cl, dl

  mov ebx, 0x500

  mov dl, 0x80
  mov ah, 2
  mov al, 1
  int 13h
  jz err

  ret```

and its not working like at all

even a commit from when it worked doesnt work anymore

bruh I was checking jz instead of jc

STILL ERROR

what teh fuck man

all the registers look good

its reset

[spare quartz]

yoooo

[lavish dove]

I hate this I hate this

[lavish dove]

oh this is cool

[lavish dove]

oh hey this worked

for some reason it was erroring on a specific sector

bruh

why is it a random value now

it wont read the first sector

why

and now it doesnt work but is still giving me an error?

[timid quartz]

https://mastodon.social/@AtanasE/113902412815255388

LOL

[lavish dove]

lmao

[lavish dove]

well now instead of giving an error it wont read the sector at all

[lavish dove]

the working commit doesnt work!?!??!

[pastel tinsel]

@proud creek

[spare quartz]

something..

[proud creek]

lmao

[spare quartz]

okay that wroks

[spare quartz]

wow

this whole time

RTC was causing crashes

[timid quartz]

Lol

What part

[spare quartz]

i don't know yet

i was just stepping through the serial writer cause it looked like that was the issue

but something in RTC is bugging out

[timid quartz]

gfg

[spare quartz]

bad game

[timid quartz]

obligatory “if you had written it in Rust…”

[spare quartz]

well you see

the RTC uses assembly

and no language can really be used there aside from it

[timid quartz]

hmm just…use gcc to generate assembly from Ada

Or C if you really have to

[spare quartz]

thats what im doing

im pretty sure whatever inline assembly is being used is not being contained safely

[timid quartz]

Yeah so

Write some high level language code

Generate assembly from it

Use that generated assembly instead

[spare quartz]

oh you're saying use objdump

[timid quartz]

No I’m saying gcc -S

[spare quartz]

thats way too complex

objdump --disassemble=<symbol> is easier

[timid quartz]

typical ada user preferring the more verbose answer

[spare quartz]

its not verbose if its already done for me ...

[timid quartz]

you don’t understand

[spare quartz]

isn't that how all ai works

[proud creek]

pretty mych

[timid quartz]

you: "oh my hand-written assembly memcpy is broken"
steps:

1. nano my_memcpy.c
2. create memcpy in C
3. gcc -S my_memcpy.c
4. Copy from generated assembly and paste into rts

[spare quartz]

okay but why not just

[timid quartz]

because the code you made earlier was broken

and why fully compile just to objdump

[spare quartz]

because this isn't isn't within a complete file of assembly

it's a bunch of small in/outs which are inlined

it's easier to just look at the completely disassembled function w/ the inlined code at least for me

[spare quartz]

687

i can count

x86 isnt real

NO

NO WAY ITS A MEMMOVE ISSUE

wait no i just used c

fml

okay it crashes here

the first exception is "INVALID_OPCODE" so

hmm

i think i need to tell it not to vectorize

looks like that fixed it

aha

that also fixed the 15+ byte crashes on strings!

so im NOT a bad coder

[lavish dove]

I am 😭

I literally plugged in the registers manually

and it STILL ERROR'S

like

im pretty sure its a problem with qemu now

[spare quartz]

probably is

i was gonna ask if you've tested it on other vms

cause there can be a lot of diff behaviors

[lavish dove]

yea

im gonna try it with different accelerators first because theres no fuckin way its a problem with qemu

bruh it works with qemu+kvm but not just normal qemu

[spare quartz]

thank god im no longer limited

[lavish dove]

wait were you using like xmm registers for strings somehow

[spare quartz]

yeah GCC was trying to use xmm for large (15+ bytes) string concat

[lavish dove]

dyamn

[spare quartz]

since i haven't added CPUID yet, kernel doesn't know my qemu doesn't support fp so

it goes kaboom

[lavish dove]

waa

[spare quartz]

i love segmenting

holy CRAP ada interrupts are complex

it gave up

[lavish dove]

fr

why does it haved to be

like

increments of 16

and its such a cool idea then they plaster it and throw it away in even protected mode

[spare quartz]

im such a good programmer fr

alright

i think this is good enough

changed 0x107DFE to 0x007DFE and yup

shocking

oh right

gotta clobber the flags since TEST sets ZF

[spare quartz]

nice

おきつねマンガ描きました

[timid quartz]

GJ that’s grammatically correct

[spare quartz]

:3 33 3 33 33 33 3 3

that was written by bayachao silly

[timid quartz]

o lmao

[spare quartz]

anyways GDT is still beating my ass

and ive made this strange type to cap them

https://tenor.com/view/always-sunny-frank-oh-my-god-i-get-it-gif-22328165

[timid quartz]

I must say for your sake

Bayachao didn’t write a 100% grammatically correct sentence

[spare quartz]

oh my god

[timid quartz]

It’s common to omit some particles and bayachao omitted one, which while technically not wrong isn’t completely right either

[spare quartz]

keep talking i've jusut got an idedae i need to write down

[timid quartz]

For your sake you need to know

The completely correct sentence would be
おきつねマンガ**を**描きました

The を explicitly denotes the direct object

But it’s common to omit that particle especially when speaking more casually

[spare quartz]

noted noted

[spare quartz]

sorry i just got reminded of the book you sent i have sitting in downloads i haven't read yet due to kernel stuff

i wanna try reading it on my kernel

aw crap i gotta do art stuff for modding soon

[timid quartz]

the book?

[timid quartz]

OH

lol

[spare quartz]

AAAASS

i dont have high hopes for this code

but here goes nothing

seems to have worked?

lemme add a divide by zero

uhmmm

it should've written an excception..

i guess not

GDT= 00000500 00000020

hey!!!

it worked!!!

by default it'd be
GDT= 00000000 00000000

[timid quartz]

gdt = 0x3

x3

[spare quartz]

can't do

the gdt is two values

yooo

my assembly works!!!

[timid quartz]

far

more like fard

[spare quartz]

idk what to name it

since it's ... far

no exceptions thankfully

update i forgot to actually run the code

uh oh!!!

ohh

it wants a SELECTOR

not an address

[spare quartz]

hm

so for some reason the reloading is causing a segment not present exception

but the GDT is being implemented and read fine

[timid quartz]

an @spare quartz database?

[spare quartz]

https://atpflightschool.com/become-a-pilot/airline-career/atp-certification.html

go to my school

ooowwwwwwwww

okay soooo

0 00 xxxxxxxxxxxxx ...

hmm

i should just shift it to the .... left? 3 bits?

no that didnt owrk

私あなたを殺す!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

ええ、きみ!!!!!!!!!!!!!!

[spare quartz]

mr aera when you see this

did thisssss make sense

[spare quartz]

i understand why the interrupts were failing last time now

i was in protected mode implicitly by the BIOS, which doesn't support the IVT

[proud creek]

Intermediate value theorem?!?!

[spare quartz]

idk what that is nerd

[proud creek]

Learn calculus smh

[spare quartz]

no

what has calculus ever done for me

IDT is being set...

[lavish dove]

average idt behavior

[timid quartz]

私は smh

You could also omit that entirely and leave it inferred that you will be doing the killing

[spare quartz]

LETS GOOOOOO

the interrupt handler work!!!

[spare quartz]

bad news is i cant erturn out of it cause it corrupts my stack

[spare quartz]

I GOT INTERRUPTS ACTUALLY WORKING :3

rn it goes into a trap handler which is bad but im gonna try to fix that

[timid quartz]

One interrupt handler:
print("Silly, we don’t do interrupts here!!") and exit

[spare quartz]

i wish it worked like that

these are super sensitive

printing causes the IP to totally shit itself

and by the end of the handler ... its at the bootloader

[timid quartz]

Yeah cause printing needs an IO interrupt

[timid quartz]

so just return before then silly

[spare quartz]

printing doesn't need any cpu I/O ops

[spare quartz]

doesn't work

on the INTERRUPT ISRs iret does do something ... but it throws a GPF afterwards (probably not accounting for a datum)

[timid quartz]

iret?

[timid quartz]

oh ic

[spare quartz]

default_interrupt_handler applies to ALL interrupts which is why it hlts instead of iret

[spare quartz]

no_op does the same cause i cant return not knowing whats on the stack

[timid quartz]

https://baponkar.github.io/Osdev-Notes/02_Architecture/05_InterruptHandling.html

[timid quartz]

Read the bottom of that image

[spare quartz]

ah, probably need a popw

[spare quartz]

i was using pop already, but i guess NASM didn't insert the right operand size of it

probably was inserting a popd or popb

this should be good

oh right

[timid quartz]

I think you wanna pop and then popw

[spare quartz]

wait no thats correct

[spare quartz]

INTERRUPT isrs don't push an error code so not needed

its just the vector number

[timid quartz]

well if you wanted to do it in the correct order

[spare quartz]

oh i see what you mean

[timid quartz]

It would be better to add 16 to rsp

So you can preserve eax

[spare quartz]

esp in this case but yeah

awit

ughgugh

don't need the pop

ignore me im a little stupid sometimes

check_exception old: 0xffffffff new 0xd
1: v=0d e=f9ec

gpf..

[spare quartz]

hold on

making a pr

https://github.com/baponkar/Osdev-Notes/pull/2

*Before the ret, this code is executed, to tell the PIC that it's OK to send any new or pending interrupts, because the current one is done. The PIC doesn't send any more interrupts until the cpu acknowledges the interrupt: *

okay so theres still a gpf in no_op

gonna go into gdb and check out why

BUT FIRST
makefile modfiications

[timid quartz]

🤓

[spare quartz]

it's so ugly

[timid quartz]

You mean BEAUTIFUL

[spare quartz]

❌

[timid quartz]

makefile ❤️

[spare quartz]

uhhhgh

is there a way to make qemu run

but NOT wait for it to exit

and jump into gdb

[timid quartz]

uh

qemu -g I think

https://www.qemu.org/docs/master/system/gdb.html

[spare quartz]

qemu-system-i386: -g -d: Option not supported for this target

[timid quartz]

-s or -S by bad

[spare quartz]

that just enables gdb debugging, not opens gdb

-S pauses execution

[timid quartz]

Yeah so you have to use -s

[spare quartz]

i am

[timid quartz]

And then gdb attach

[spare quartz]

okay but

makefile is pausing waiting for qemu to run

[timid quartz]

oh lmao

Put an ampersand after the qemu run

[spare quartz]

okay that worked

thank you :3

[timid quartz]

Yeah it just backgrounds the qemu process

[timid quartz]

you can get it into the foreground with fg

[spare quartz]

nice

yay it even runs the remote well

just need to make it go into layout asm too

[timid quartz]

GNU needs their own executable format called GNOME

[timid quartz]

GNU NOrmalized Multipurpose Executable

[spare quartz]

OK

note to self

REDIRECT QEMU TO A FILE

god gdb is so easy to segfault its insane

[timid quartz]

oh?

u sure it’s not just ur kernel

[spare quartz]

its gdb segfaulting so yeah i'm sure

like i can just unhook qemu, run it again, target remote and it has a 50% chance of segfaulting

making me have to do file, remote, layout, break all over again

[timid quartz]

well dont unhook qemu

ez

[spare quartz]

how else do i reload it 😭😭 its locking me filse...

[timid quartz]

u press C to continue duh

[spare quartz]

that doesn't reload the kernel dolt

kids these days ...

[timid quartz]

no but if it’s locking you out

[spare quartz]

no like

filesystem lock

[timid quartz]

oh

bad kernel

[spare quartz]

YOU'RE an l

NO

my kernel won't have fs locks 😎 itll uhmm

itll do the presidential elections everytime a handle is aquired

[timid quartz]

Hell naw your computer gonna vote for Trump

[spare quartz]

😭

there

am i a real programmer yet

[spare quartz]

what teh fuck

windwos

no

[timid quartz]

no cause you cheated with multiboot & grub

[spare quartz]

HOLD ON

IM PLAYING A BAYACHAO GAME

.... that i pirated cause i cant afford it :<

[timid quartz]

make ur own bootloader u cant afford multiboot or grub

[spare quartz]

but grub is free 🥺

[spare quartz]

ugfghuguhguuh

[spare quartz]

it uses japanese words even in the translated version!!!

oh yeah

everyone hates me in this game :<

[proud creek]

TRUE @pastel tinsel

[full berry]

@pastel tinsel (or anyone else who knows) what's the name of that one open source service to make online documentation for your projects

like for code and shit

[spare quartz]

read the docs

[full berry]

that's semi paid its not that one

[rustic vine]

vitepress

[spare quartz]

its open source

i could also recommend gnatdoc but... thats not applicable to you!

[rustic vine]

mkdocs is good too I've heard

doxygen for cpp if you want api docs

[rustic vine]

average ada tooling that isn't used by more than 2 people

[full berry]

i think this is what i was looking for

maybe

im not sure we'll see

[rustic vine]

I think vitepress looks good

if you're undecided

[spare quartz]

its good tooling!

[rustic vine]

looks similar to docusaurus (but imo better)

[spare quartz]

IT IS TIME

TO DECODE

RPGMAKER FILES!

EXPLORER CRASHED!

[proud creek]

There’s a lot of them

[spare quartz]

:33333333333

[spare quartz]

i finished it

its a nice game

https://youtu.be/gdEuJ1hAVhQ

HOLD THIS

[spare quartz]

ALRIGHT!!!!! !! !! !

its back to cod ing

and art

[proud creek]

@spare quartz a you database

[spare quartz]

aera already sent this doofus

[proud creek]

die

[spare quartz]

@proud creek here for posterity

[proud creek]

smh

[spare quartz]

im gonna post furry art

pls ignore

[spare quartz]

i am addicted :3

[rustic vine]

@spare quartz yo did you see that F-35 that crashed in Alaska

I just saw a video about that now

[spare quartz]

yeah i spoke to aera about it earlier today

[rustic vine]

up above?

[spare quartz]

in dms

[rustic vine]

oh alr

[spare quartz]

commander of the division for the fighter jet came out and said it was some in-flight malfunction

during the landing

pilot ejected safely but... idk what made it fail so weirdly

[rustic vine]

ye looked like it was just doing like in place rolls and falling

thats so weird lol

its like it wasn't flying

and just falling instead

[spare quartz]

engine was still on too

its so weird

[rustic vine]

oh really?

huh

[spare quartz]

you can hear it

[rustic vine]

oh yea

so not really any info atm I assume

[spare quartz]

https://fixupx.com/DaOfficialVigil/status/1884414311034212846

[rustic vine]

ig we'll find out sometime in the future

[rustic vine]

its just a scratch

[spare quartz]

obv not the original jet since it was probably totally obliterated but

funny image nonetheless

if it was a programming issue i blame it on C/C++

should've used SPARK

[rustic vine]

disaster

well glad everyone is ok

super interested to find out more when that comes out

[spare quartz]

not the engineers 👍

[rustic vine]

LOL

[spare quartz]

well actually one set of engineers is happy

[rustic vine]

but idk how much we'll get so

[spare quartz]

the people who made the ejection seat get to increment a counter

[rustic vine]

theres prob one set of engineers that found this bug but got ignored

[rustic vine]

oh yea, that too

[spare quartz]

https://martin-baker.com/ejection-seats/us16e/

gotta say they have pride in this work

[spare quartz]

honestly if it is a software bug

i wonder how they push these updates out

the computers they use on jets is super weird

(and relatively limited since they're shielded + from ~2006)

[rustic vine]

have they upped this number yet

[spare quartz]

their twitter account did

[rustic vine]

yea I wonder how they enforce everyone update versions

actually idek how their versioning works

or if theres versioning

[spare quartz]

https://fixupx.com/MB_EjectEject/status/1884551492679450774/photo/1

[rustic vine]

🙏

goated

[spare quartz]

honestly wish i could buy one of those seats w/o the rocket booster

looks comfy

some replicas come in at thousands though

[spare quartz]

the idea of a "Firmware update available. Update?" and "Do not power off the engines." is funny to me

they probably just flash them though

[rustic vine]

LOL

do not unplug jet from ground power until the update is complete

[timid quartz]

lmfao I watched DeepSeek get censored in real time

I turned on the thinking model and saw it mention something about Taiwan during the thinking

[spare quartz]

yeah I’ve had it do that a lot

[timid quartz]

and it was mid-response when it suddenly got censored lmao

augh deepseek ddos moment

cmonnnn

@spare quartz it's getting ddosed

[spare quartz]

local model :3c

[timid quartz]

ughhh I don't wanna turn my windows pc back on

and my macbook absolutely fucking chugs cause it has no decent gpu

[spare quartz]

Well

[timid quartz]

google gemini it is

[spare quartz]

I’m on bed…

And it’s working for me

[timid quartz]

ok but ur laptop has gpu

[spare quartz]

I have a phone idiot

My laptop is from 1998

😭

[timid quartz]

and you're running a model on your phone?

or do you have an interface b/t your phone and pc

[spare quartz]

Noooopeee

The web model is working fine!!

[timid quartz]

it's down for me

[spare quartz]

Odd?

Only like

The search feature is broke

[timid quartz]

website inf loading type deal

[spare quartz]

Yeah for me it loads fine

Occasionally it drops out mid req but

Overall it can think

[timid quartz]

it's not my college blocking it either

it's actually getting attacked lmao

[spare quartz]

Also…

Unfortunately I learned my first Japanese word on accident :<<<

[timid quartz]

either that or I have been disconnected from deepseek by the CCP

[spare quartz]

latter, you’re too weird for them…

Harry get a pass for aera

[timid quartz]

no doesn't load on my other phone

it's legit down

[spare quartz]

Ooooookay

It dropped for me too

🙏

OpenAI is really trying to make their money count

Wa…ta…shi

[timid quartz]

What is it

[spare quartz]

SIGHHH

[spare quartz]

this

rote memorization or whatever

[timid quartz]

私

[spare quartz]

I heard it so much I had to get its meaning in my head

I
