[hazy saddle]

So like

That might be why?

I wonder if @cyan bison s computer has a ps/2 port and still hangs there

And it was differing bugs??

[cyan bison]

my laptop has real, actual ps2

[hazy saddle]

Is that the one you tested it on and it failed?

Or was it the arrow lake machine

[cyan bison]

arrow lake machine

havent tested on my laptop yet

[hazy saddle]

Could you test it on both if you have a second

Preferably atleast the arrow lake one

[cyan bison]

then id have to reboot

[hazy saddle]

Because I want to support arrowlake hardware

[hazy saddle]

[cyan bison]

and like thatd be like really like annoying

[hazy saddle]

I know they deprecated x1apic but idk if they did ps/2

macOS chips are a bit diffrenter though so maybe

[hazy saddle]

Then you wana try the buggy version and the patched one?

[cyan bison]

i can try the patched one on one of my test subjects from haswell era

[hazy saddle]

Does OBOS use ps2 on that (arrowlake) machine?

[hazy saddle]

Iirc I’ve already validated haswell

[cyan bison]

no, obos doesn't boot on the arrow lake machine

[hazy saddle]

[cyan bison]

hangs while tryna use the lapic

(x1apic)

[hazy saddle]

No x2apic driver

[cyan bison]

Steal mine

[cyan bison]

im good

[hazy saddle]

No trust me it’s really good

(It’s not that good but it’s not bad lmfao)

[cyan bison]

if it works™

[hazy saddle]

Before you sleep can you reboot and test it on arrow lake

Maybe I should make an ISO for extra prints on the fucking PS/2 code

Just to nail it done too

[cyan bison]

remind me

it's only ~20:00 rn

so im not sleeping for a few hours

[hazy saddle]

Wait I think I know why it’s fucking up maybe

Leme read the code

Errrm what the sigma

This could be hanging

Maybe

[cyan bison]

oh wow a polling loop... hanging

[hazy saddle]

[hazy saddle]

If there is zero ps/2 controler

This would uhhh

Ermmm

Causebissues

I should add a timeout thing

So it can timeout

[cyan bison]

there should've always been one

[hazy saddle]

To be fair

I stole this ps/2 init code form a friend

[cyan bison]

i think depending on the chipset, inb on non existent io ports returns 0xff

[hazy saddle]

🥀

[cyan bison]

and this friend vibecoded it?

[hazy saddle]

Yeah 🥀

The code is super basic

[cyan bison]

then why is he a friend 🥀

[hazy saddle]

So idk how to redo it without copyright or whatever issues

[hazy saddle]

She* and I feel bad 🥀

And I didn’t know at the time 🥀

[cyan bison]

(mb)

[hazy saddle]

Honestly they sent me a lot NSFW before and I’ve been meaning to distance 🥀

And they use a bitmap allocator 🥀

And didn’t wana use mine

Better one

🥀

[cyan bison]

ah yeah bitmap allocators, very NSFW

[hazy saddle]

Unprompted

Nah separate

[cyan bison]

uh

[hazy saddle]

Yeahhhhh

[cyan bison]

that's concerning

[hazy saddle]

Very

I just feel bad

And I host part of there website

So like

[cyan bison]

their*

[hazy saddle]

I just kinda stay away with a 10ft poll

[hazy saddle]

FUCK

https://tenor.com/view/minor-spelling-mistake-major-spelling-mistake-spelling-mistake-gif-25140477

Let me uhhh

Add the timeout

🥀

Il probably also change them to 50ms max

[cyan bison]

have i mentioned how much i hate xhci yet?

[hazy saddle]

🥀

[hazy saddle]

No but please do

[cyan bison]

I FUCKING HATE XHCI

I FUCKING HATE XHCI

I FUCKING HATE XHCI

(limit reached before the bot mutes me)

[hazy saddle]

I can’t hear you

Say it louder

[cyan bison]

I FUCKING HATE XHCI

[hazy saddle]

What has XHCI done this time 🥀

[cyan bison]

xhci: port reset timed out

xhci: trb completed with code 0x4

(0x4 is usb transaction error, the most vague code in the entire spec)

if only i had never made the promise that i would try xhci then my life would be a lot better

[hazy saddle]

You know what the silver lining is of this shit

[rotund furnace]

I think he said something about no liking xhci

[hazy saddle]

You can help others in the future

With this knowledge

And save others the pain

And even make a document on how to make an XHCI driver

That’s more simplified

[cyan bison]

already exists

but it costs money (i pirated it)

[hazy saddle]

And covers common mistakes

[hazy saddle]

Yeah but a cool one

[cyan bison]

((libgen is a very sketchy website, i found out))

[hazy saddle]

this should fix that lil shit big

@peak cloak

this may not work because keyboard

but it will finish most of it

[peak cloak]

ok last test lelelel

[rotund furnace]

> cat /bin/cat

[hazy saddle]

and if you want il make a special ISO to auto boot into badapple

mayb

[peak cloak]

mayb

[hazy saddle]

If the other ISO works

Il make that special one

[hazy saddle]

#!/bin/cat
this is a quine

[peak cloak]

shows the stupid serial init thing

WHY DO YOU EVEN HAVE IT ITS USELESS

[hazy saddle]

WHAT DO YOU MEAN

IT SHOULD BE DISABLED

[peak cloak]

"do you have serial port at blah blah blah"

[hazy saddle]

Did I give the wrong ISO

[peak cloak]

aint no way

[peak cloak]

Unless it reports as running under a hypervisor

Pls

Work

[hazy saddle]

https://tenor.com/view/rochester-institute-of-technology-washing-machine-dryer-gif-2639271970500434454

@peak cloak I swear to jod

If this prints the serial message

It shouldn’t

[hazy saddle]

https://tenor.com/view/man-destroys-pc-harold-slikk-new-computer-haroldslikk-escortedcomputer-gif-23496313

[peak cloak]

why u need serial so bad anyway

[hazy saddle]

I need it to boot

It shouldn’t even be enabling seriel unless it’s on a goervusor

Hypervisor

Can you send me the full logs of the latest ISOS

[peak cloak]

make boot option --enable-serial or whatever

just do that

please

[hazy saddle]

I did

I literally did that

[hazy saddle]

Look at this

Look at zis

seriel=hv

It means only enable on hypervisor

Also it’s ps2 breaking it not serial 😭 @peak cloak

[hazy saddle]

This should of fixed it

@peak cloak you got the log

I’m going to sleep

[peak cloak]

a

oops

[peak cloak]

oh

[hazy saddle]

Depending on log

Il try and patch

You gotta work with me here

[peak cloak]

give me a moment

[hazy saddle]

Or like uhh

Download me repo and fix yourself

💀

Because I’m sleepy

[peak cloak]

no i have my own crappy OS

contribute to it instead

/j

[peak cloak]

you want me to try this one?

[hazy saddle]

Did you not do that one

Already

[peak cloak]

i think i did

ok so the latest one

[hazy saddle]

This one has zero code changes

But I tried to do a fresh build

So uhhh

Also send logs

[peak cloak]

k

[hazy saddle]

And il make an extended logging version after

[peak cloak]

send logs as in

just screenshot

??

bro my mac also sleepy the screen just closes

[hazy saddle]

[peak cloak]

werks

no keyboard

[hazy saddle]

What happend with the old ISO

[hazy saddle]

Well yeah there’s no XHCI

Or EHCI

Good thing our good chum @cyan bison is here right

[peak cloak]

victim

[hazy saddle]

They are now the server XHCI person

[peak cloak]

cool

i think im now the evalynos tester person 😔

lemme do 2006 macbook actually

[hazy saddle]

No your the kvass cat

[peak cloak]

i dont think i have ever seen you do anything in kvass

anyways

behold the ultimate test

nothing that nobody complies with

macbook from 2006

[hazy saddle]

I watch the channel from time to time

[peak cloak]

fair

[peak cloak]

booting now

nothing happened

i think limine cooked itself

lol

[hazy saddle]

Was it limine

Or my kernel

[peak cloak]

limone

nothing is happening

[hazy saddle]

No limine screen?

[peak cloak]

no screen

not even black screen its just at the boot picker

[hazy saddle]

cc: mint?

[peak cloak]

WHY WOULD THEY COMPLY WITH EFI 1.0

[hazy saddle]

[peak cloak]

if you ping them over that crap it might just be a troll ping

do it

[hazy saddle]

I mean is it a troll?

[peak cloak]

idk

[hazy saddle]

It’s technically a bug with limine?

[peak cloak]

what are limine system requirements

[hazy saddle]

Limine works on BIOS

I’d presume it should work on that old of EFI

Is that UEFI

[peak cloak]

no thats just efi

[hazy saddle]

Or JUST efi

[peak cloak]

before it was uefi

[hazy saddle]

Damn

[peak cloak]

crap

no technicality

im gonna go boot from usb

somehow

theres no usb bios boot

trying again

[hazy saddle]

[peak cloak]

ngl i wish i had a powerbook

the aluminum g4 one

i can troll my parents with seemingly two identical laptops

[hazy saddle]

[peak cloak]

boot picker cd sharted itself

[hazy saddle]

Does limine not support EFI EFI?

[peak cloak]

retry

[hazy saddle]

I wonder if it was spesific if it was between EFI/UEFI

[peak cloak]

it just doesnt have a web cam and the battery slots are different design wise

hardware wise they are literally different things entirely

[peak cloak]

idk

ok so i booted the 32 bit one

[hazy saddle]

My kernel uhhh

Isn’t 32bit

[peak cloak]

whatever

i have another thing to share though

[hazy saddle]

It would fail to load

[peak cloak]

lol it death'd

[hazy saddle]

Well

It DOES SAY

It’s a bug

Right there

[peak cloak]

it say report upstream

[hazy saddle]

I mean this is your computer

And upstream is right here

[peak cloak]

nah

[hazy saddle]

So

[peak cloak]

they dont support it

[hazy saddle]

[peak cloak]

im not gonna be a total poopybutt over it

instead i will make it a selling point for kv-

[hazy saddle]

Is that Mac even 64bit

Because if not idgaf myself

[peak cloak]

it has a core 2 duo

but the EFI is 32 bit

[hazy saddle]

Is that 64 or 32bit

[hazy saddle]

Oh

[peak cloak]

because apple engineers were programming it with one hand probably

[hazy saddle]

I don’t think my ISO bundles the 32bit limine

Actually

[peak cloak]

i booted your os on a core 2 duo are you demented

[peak cloak]

no it does

[hazy saddle]

So how is it both booting and not?

[peak cloak]

🤷

you also ship the RISC V and AARCH64 efi's

[peak cloak]

nevermind they look different

they more resemble each other when opened but thats only the keyboard

[hazy saddle]

Wuh

uhhh

how many drugs u eat

[peak cloak]

my macbook eats a bunch

it said all of them exist

[hazy saddle]

@peak cloak making the special version

i may tomorrow do a cli argument to have a set of KBD inputs to preplay

and | means enter

[peak cloak]

elebab

[hazy saddle]

its badapple

reversed

because how buffer work

@peak cloak

try zis

Il probably have
kbdpreplay=+|badapple|+

Make the same as that

The pluses are the dilimeter of the sequence

and the bar means enter

But @peak cloak

This is now

Bad Apple

On Apple device

Get ready

[rotund furnace]

wait do apple devices just not have secure boot?

I just fucking wondered how I can boot your os on my laptop without disabling it

oh wait I think I have system integrity protection off

[hazy saddle]

Apple laptops are way less locked down than phones

They are just a lot more esoteric of hardware

[rotund furnace]

nah sip should block unsigned efi apps

difference is sip cannot be disabled on the mobile versions of macos (ios, ipados, watchos)

[hazy saddle]

you can disable that though

[hazy saddle]

Which is iOS?

[rotund furnace]

yeahhhh sorta

[hazy saddle]

@peak cloak how are you getting it to boot on the Mac?

Also did the special ISO work?

[cyan bison]

no thats someone else

[hollow crater]

gummi has a working xhci btw so u can take a look there

charmos ftw

[hazy saddle]

I’m planning my XHCI stuff after my x11 port

Right now I’m trying to get a shell working in userspace

And then bash

And then maybe try and get job control in bash if that wouldn’t be toooo bad

And then it’s onto x11 and maybe dbus if it’s needed and then to get xfce or some other DE

Once I have that il start on XHCI and EHCI (no USB 1.1 if you need that just use ps/2 lmfao)

And then a TCP/IP stack

And maybe a hypervisor snuck in there

I know this is alot of work to do but it’s just high level goals

[hollow crater]

each of these could take a year from me separately 😭
aside from the shell one, and bash

[hazy saddle]

X11 has an end of year goal

So it is gonna take a year

x11 is my New Year’s resolution

[hollow crater]

ig to me i would die happy if i can get to have a mlfq scheduler with smp by the end of the year

[hazy saddle]

(This does not include a DE to be clear)

[hazy saddle]

Oh SMP is after bash

Once I have bash working

I’m going to do a full code cleanup

Inspect every nut and bolt

Fix all the naming

Get it to be perfect

Then it will be time to do SMP and fuck all that up

[hollow crater]

fair
i wanna have smp before doing any userspace shit cuz im afraid i'll make fucked up decisions incompatible with it if i left it after having the base functionality

[hollow crater]

[hazy saddle]

Userspace isn’t much different than normal multitasking

[hollow crater]

mhm makes sense

[hazy saddle]

You just spawn a kernel thread and then have that jump into userspace

And then it’s exexuting

[cyan bison]

skill issue, i just start the user thread in user mode

[hazy saddle]

Make sure to allocate a diffrent CR3 thing and a big enough kernel stack because that thread stack will be doing system calls

[hollow crater]

o i meant more like
a working userspace
ie minimal syscalls and user threads etc

[hazy saddle]

Ahhh

if you just port a little bit of mlibc

It won’t be that bad

POSIX really helps you make not stupid things

Though

I don’t listen to posix and I made a cursed abomination

But it somehow still runs doom

Lmfao

[cyan bison]

my guy, toaster runs doom

[hazy saddle]

But the mlibc glue is cursed as fuck

[hollow crater]

straying away from holy posix is the reason this world has all that evil 🙏
ig i will personally go all posix
my dumdum probably wouldnt know any better so

[hazy saddle]

And I have like 7 random fucking system calls it has to use

Because I diddnt posix them

Once my VFS is proper

I will be making the stuff posix

Like to get the frame buffer

You will MMAP the file

And to get the size info and shit

You will use IOCTLs

🥀

[cyan bison]

im sry but mmaping files is vmm not vfs

[hazy saddle]

My open() call cannot even see non tarFS files

So it is VFS work

Technically

Also it still has to use some of the VFS right

So MMAP can check where to map from

Etc

And IOCTLs

[peak cloak]

apple is not bad

[hazy saddle]

No no

My bad apple

[peak cloak]

balenaetcher on a usb, restart with option key, "EFI boot"

there's 2 efi boots though i pick the first one

that first one works fine

[hazy saddle]

Nice

[peak cloak]

macbooks have full uefi

[hazy saddle]

This fancy one

Should work

[peak cloak]

they just dont have much pc compatible crap

[hazy saddle]

This should auto play the keys needed

[peak cloak]

k

also test if pc speaker is there

[hazy saddle]

[peak cloak]

also i text on discord on a newer macbook air but it doesnt have any normal usb ports so i just airdrop the iso onto the crappy mac which that has balenaetcher

[hazy saddle]

Lmfao

🙏

[peak cloak]

the balenaetcher is outdated too because mac os is the 2017 version

[hazy saddle]

Uhhh @peak cloak

Did it ever work

[peak cloak]

oh

yeah

it did

forgot to send

bad apple works but no sound

[hazy saddle]

Can you send photo

[peak cloak]

later my desk is crap rn

[hazy saddle]

Okay well @peak cloak says the patch works

So when I get home il push this

Play game games

And then get started on the VFS rework

[peak cloak]

what if i lied

no it works though

crap i forgot the photo

[hazy saddle]

I really want a photo

[peak cloak]

brb

[hazy saddle]

I’m thinking for my driver servers I may have them be mostly bundled together

And written in c++

Like all my pcie drivers will be inside pcid

ACPI in acpid

Etc

And then they can talk internally easily

And they don’t need to go outbound IPC wise much

And it makes it so I have less servers

But internally they will all be separate threads for the most part

Seperated with C++ classes

A lot of the drivers i want many instances off too

So c++ works well and userspace

And the kernel space may have a few duplicate drivers for init shit until they startup

For like swirls

Serial

But then userpaace can take over and init all serial ports properly

And have ACPI to do it right etc

For keyboards and mouse I’d probably have inputd and then do zero copy IPC with shared pages for the buffers of inputs that that server can glob

@peak cloak what’s your opinion on this

Same for @rotund furnace

[peak cloak]

idk maybe

[gentle void]

okay so

if you do want to write drivers in userspace you need to think about how to handle interrupts

because you need to forward the interrupt handlers to the user process obviously

[hazy saddle]

I was gonna have them be a waitable FD

And then the ISR system will plug into that and set the FDs to awake for the schedular

Mainly I’m trying to get what I already have nice

Because my VFS is utter shit

I need to rework my heap a bit

Get my PMM to use buddy stuff

And get actual VMM working so I can locate virtual address space adddresses

Allocate*

And then I can actually get new features like that

Just napkin planing things right now because I can’t code atm

[gentle void]

also you will need IOMMU drivers

(fun)

the second a device can DMA any physical address it's over for your system

that kind of defeats the entire purpose of putting drivers in userspace :3

[hazy saddle]

What about systems without an IOMMU

Also my main point was to seperate complexity imo

[cyan bison]

panic("no iommu");

[hazy saddle]

And security separately

I would use capabilities somewhat so no random program can do this shit

[gentle void]

tough luck then

[hazy saddle]

[gentle void]

you can't support them safely

[hazy saddle]

Then can i support them dangerously

[gentle void]

actually this is a good point

thank you for this idea

i will be stealing your idea

:3

i had kernel modules before

but userspace drivers sound cooler

[hazy saddle]

And it’s less work and still somewhat safer even lacking an IOMMU

[gentle void]

not exactly

in kernel mode the kernel can manage devices

If you let a user program map shit it will explode

[hazy saddle]

True

I mean the kernel can still manage it no

Somewhat atleast

And your gonna be trusting the drivers you make anyways similar to the kernel

And that’s only on non IOMMU devices

[peak cloak]

why

if its like a freelist then why

[hazy saddle]

Contiguous physical memory

[peak cloak]

the fart works already dont nuke it

[hazy saddle]

I need that for DMA

[peak cloak]

then allocate contiguous physical memory with your freelist

[hazy saddle]

That can fail

With a buddy allocator it’s really easy to get 2mb to 4kb pages and powers of two inbetween

[peak cloak]

how

[hazy saddle]

Fragmentation

Buddy allocators automatically defragmenter themselves

[peak cloak]

oh

defragme-

yeah no i just cant understand buddy allocators

you do whatever

like literally i cant understand how the fart works

[hazy saddle]

It’s actually really easy

[peak cloak]

tell me

[hazy saddle]

The freelist is stored in the free pages themselves

So when you XOR an address it points to the physical page

Which has the actual free list node

and then you have many ranks of free lists

And then to allocate you look through them and split as needed

And when freeing you XOR to check if you can merge blocks

And blocks are always paired

So it’s really easy

And just works

[peak cloak]

really easy they all said

[peak cloak]

where do you get the free pages

[hazy saddle]

The fuckinf memory map

You use the pages themselves to store the information

[peak cloak]

no fricking crap sherlock

oh

[hazy saddle]

So you don’t even need a boot strap allocator for your initial free list pages

[peak cloak]

wait i literally asked it

oops

[hazy saddle]

https://tenor.com/view/oh-you-lets-do-it-great-idea-nods-gif-9095233599829826537

@peak cloak does that make sense

And then you use HHDM to make it easypz

No HHDM?

Krill issue

https://tenor.com/view/shrimp-as-that-clash-royale-hee-hee-hee-haw-gif-25054781

[peak cloak]

MAKE MY OWN

[peak cloak]

honestly not really

severe brain capacity deficiency

[hazy saddle]

The pages themselves that are free yeah

You just store the node in there

For the free list

And when you do phys addr XOR block size

[peak cloak]

k

[hazy saddle]

You get the buddy if that block

And that buddy also stores the freelist node

That you need to use to operate

Like to remove it or add etc

Or to check status

[peak cloak]

ok i think i understand

or not

a sec

[hazy saddle]

And then you just store a bunch of pointers to the heads on the BSS in C

And then when starting it you fill in all of the blocks the highest they go

And because the free blocks themselves describe themselves

And then when you give it out

You just zero it out

Because the metadata isn’t needed when it’s allocated

As it’s a free list

Not a not free and free list

And you can use PFNdb too

[peak cloak]

uhhhhhh

ok i think i figured it out

its a tree

[hazy saddle]

No

[peak cloak]

F

[hazy saddle]

It’s several free lists

One for each order

Like 4kb 8kb 16kb 32kb 64kb 128kb 256kb 512kb 1mb 2mb

[peak cloak]

mk

is there like an initial freelist

[hazy saddle]

@urban mulch maybe you can explain this better

[hazy saddle]

No there is no need

[peak cloak]

oh

[hazy saddle]

Because you use the free pages themselves

As the nodes

[peak cloak]

what do these freelists have in them

per order

like ik its a dumb question but like

[hazy saddle]

Like weather it’s buddy is allocated or not

And it has pointers to the next and previous

[hazy saddle]

This may also be in the PFNdb

And if you take an allocation of 4kb

And then take it’s address

And XOR it by 0x1000

You get the buddy

Because every page has a pair

A 2mb block becomes two 1mb blocks in the 1mb free list

And you keep splitting as you go down to the proper size

And when you free you check if the other block is free so you can merge it in the PFNdb

[peak cloak]

oh

[hazy saddle]

And then you delete the other block in the 1MB page

And add it to the 2mb block

[urban mulch]

Oh god is it buddy allocators again?

I have explained this one too many times already XD

[peak cloak]

now with additional challenge (i literally dont understand anything)

[urban mulch]

Ok first things first do you know how a freelist allocator works?

@peak cloak

[peak cloak]

yes

ive made one in the past

[urban mulch]

Okay, do you know what a PFNDB is?

[peak cloak]

no

database i presume

[urban mulch]

PFNDB is Page Frame Number DataBase. It is metadata about each page of accounted physical memory.

[peak cloak]

oh

[urban mulch]

You may have heard of struct page. A PFNDB is an array of those.

[peak cloak]

fair

[peak cloak]

what are the contents of struct page

is it like whether it can be accessed in usermode and other such crap or what

[urban mulch]

For the buddy allocator, there are two main important things:

1. Whether the page is in use and if so, for what
2. The order of the block to which the page belongs.

Usually you'll also have a reference count but this is not inherent to buddy allocators and we will be supposing it is not there.

A buddy allocator is effectively an array of freelist allocators.

[cyan bison]

pretty sure it also contains stuff about CoW

[urban mulch]

Each freelist within using blocks twice as large as the one below

[peak cloak]

cows live on farms not in my allocator

[peak cloak]

fair

[urban mulch]

The "order" of such a block describes how large it is. An order 0 block is one page large. Every order up, twice as large.
A block is PAGE_SIZE << block_order bytes large and aligned physically.

And here comes the neat trick: If a freelist for a smaller order doesn't have a block available, you split a higher-order block until you get one of the desired order. Splitting a block converts it into two blocks one order smaller.

When you free a block, you use the PFNDB to determine how large it is (unless you use sized frees) and find its buddy.

The buddy of such a block is found as follows:
e.g. order 0 block 0x4000-4fff has a buddy at 0x5000-0x5fff.

buddy_page_number = page_number ^ (1 << block_order) (where page_number is physical address divided by page size)

If you free a block and see that its buddy has the same order and is also free, you coalesce the blocks.

This is simply the opposite of splitting a block. since you know the address of the buddy, you can remove it from the correct order's freelist without having to search. Then you coalesce the blocks into one larger block, updating the PFNDB entry of every page in the block to reflect the new situation.

Repease coalescing checks until you can no longer coalesce, then add the result to the appropriate freelist.

[peak cloak]

a sec

[peak cloak]

where do you allocate these freelists

the start of the block or something?

[urban mulch]

The list heads are allocated statically. So you decide an arbitrary maximum order. I chose my maximum to be all the way up at 64, though no block will ever be this large in reality.

[peak cloak]

fair enough

[urban mulch]

You do of course need memory to store the PFNDB too. Choose some arbitrary location in the immediately usable memory as the bootloader reports. This overhead is acceptable.

[peak cloak]

ight

[hazy saddle]

i have the first memory region have some base metadata and pointers to the other metadata tables, the first region ofc has its own,

then thoes tables store the size of it etc and also has an array for the PFBdb and its trivial to goto master table > sub table > PFBDB entry with a few checks

its easy enough to implement and uses the memory in a region its self for it

[peak cloak]

cinema

i have to implement a pmm soon im almost done with exiting my stupid bootloader creation

helped a lot ig

(i have 1% of the idea of whats going on instead of 0.5% )

[hazy saddle]

make a ppc port of limine

[peak cloak]

you psychotic?

no

[hazy saddle]

yes why do you ask

[peak cloak]

mintsuki should do it im not porting limine

i dont want ai slop on MY architecture

(as in its easy to make a limine os)

(not in that limine is slop its not its fire)

(MAUHAHAHAHAHAHAHA)

honestly the documentation is utter poo

good

i should probably use limone when i port to the bunch of crap i have planned

[peak cloak]

claiming the entirety of powerpc for yourself is absolutely vile behavior ngl

[gentle void]

https://tenor.com/view/osamason-mj-michael-jordan-michael-jordan-gif-14320364864328848677

[peak cloak]

powerpc is 32 bit anyways

i dont know anything about 64 bit powerpc yet

i dont want any imac g5 abuse though

[hazy saddle]

https://git.evalyngoemer.com/user/sign_up
I got this properly working so people can make pull requests and shit properly on my server

I hope it works

Email is a fucking bitch

[peak cloak]

oh no

what have you done

[hazy saddle]

And it’s public

[peak cloak]

the robits

[hazy saddle]

I’m taking over codeberg

[peak cloak]

the chat gipities

[peak cloak]

host kvass

[hazy saddle]

Make an account and push it

Be my guest

[peak cloak]

i thought this was for you only

[hazy saddle]

This is a public service

[hazy saddle]

Not anymore

[peak cloak]

make pull requests for os

[peak cloak]

fair

[hazy saddle]

You can also have your own repos

I’m just doing a public service since I have the gear

Always good to have extra mirrors and shit

[peak cloak]

swear on your soul that you wont pull up my password and find where i live and post it on the dark web

[hazy saddle]

And to have a git server that’s not corpo owners

And one that actually preforms well

Unlike codeberg

[peak cloak]

random stranger on the internet vs small german company

[hazy saddle]

Hey

I’m no random stranger

[peak cloak]

unrandom unstranger

whenever mintsuki chooses to host limine on your server thats when codeberg will decide to go boom boom

[hazy saddle]

[peak cloak]

i only know of them because of limine

also apparently codeberg is a non profit

[peak cloak]

random stranger on the internet vs small german nonprofit

[hazy saddle]

Yeah they are

But they are never online

[peak cloak]

true

apparently codeberg's about page links to several other git hosting websites

sourcehut and other crap

im probably just gonna make a mirror on your crap and host kvass on codeberg probably

[hazy saddle]

Why not host on mine

And mirror to codeberg

[peak cloak]

what if you reconsider tomorrow or smth

[hazy saddle]

I won’t

Im literally planning on hardware upgrades just for this

For my birthday I’m gonna get two 8tb hard drives

[gentle void]

ddos

[peak cloak]

3 gb of hard drive storage instead of 2

[hazy saddle]

Ddos who

Me?

Ehhh ddos me I don’t care

[peak cloak]

parental figures

[hazy saddle]

You mean my grandparents

I mean like

[peak cloak]

what happened to your parents

[hazy saddle]

I don’t think anyone is gonna ddos this anyways

It’s a dinky ass git server

Not some massive as target

[peak cloak]

put ddos prevention crap too

[hazy saddle]

https://tenor.com/view/snapcube-eggman-gif-23877695

[hazy saddle]

Do I look like I’m made of money

[peak cloak]

make your own ddos prevention crap

[hazy saddle]

Do I look like I’m made of pure solid diamond

But yeah kvass always has a home my git server

[peak cloak]

no youre made of french baguette

[hazy saddle]

Oh also secret

[peak cloak]

[hazy saddle]

@rotund furnace Already has been beta testing this

[peak cloak]

WHAT OS

[hazy saddle]

Shhhhh

[peak cloak]

https://tenor.com/view/dramatic-indian-drama-character-introduction-dramatic-indian-drama-character-gif-21515381

[hazy saddle]

But yeah @peak cloak

Why not fucking have kvass there

Don’t you want to support honest workers

Who cares about non profits

[peak cloak]

im willing to host kvass on literally any obscure git hoster that exists

github is literally unholy to me

[hazy saddle]

https://tenor.com/view/austin-powers-dr-evil-mike-myers-come-join-us-come-here-gif-4627161

That’s an evil gif

But I’m not actuslt evil

You know me

[peak cloak]

you're the evil bad apple person

i do know you

probably

[hazy saddle]

What if I made it good apple and made it green

[peak cloak]

maybe

anyways im not gonna say where i actually host kvass but im gonna mirror it to codeberg and your evil website

[hazy saddle]

you will see

YOU WILL ALL SEE

its not evil

[peak cloak]

ok fine

im gonna invest early

whenever i opensource it though

bitcoin became worth like 3 bazillion mario coins

[hazy saddle]

just slap MIT

call it a day

oh btw @peak cloak

[peak cloak]

WJHAT

[hazy saddle]

its auto all rights reserved

so like feel free to pushit

[peak cloak]

wdym pushit

ok honestly lemme just enter the kernel like a sane person and then im gonna open sauce it

ok i return

[hazy saddle]

@peak cloak this should be enough CYA right

[peak cloak]

deeta integirty

cant even typo a typo

[hazy saddle]

there is no typo

[peak cloak]

[hazy saddle]

O

[peak cloak]

keep it

make the word italic and refuse to talk about it MUAHAHAHAHAHAHAH

[hazy saddle]

Sorry

Already fixed

[peak cloak]

crap my suggestion failed

anyways

[hazy saddle]

You should check your DMs

[peak cloak]

why did you send me a picture of a mcdonalds in australia

[hazy saddle]

[severe marlin]

Was it engadine maccas (we had a prime minister claim to have not shit himself there)

[peak cloak]

i lied

MUAHAHAHAHAHAHAHAHAH

also WHAT

[severe marlin]

there's a clip of him telling the news that "I did not shit myself at an engadine maccas in 1997"

[hazy saddle]

(He shit himself)

[severe marlin]

I can neither confirm nor deny that

[hazy saddle]

I am confirming it

[hazy saddle]

Thinking about my tmpFS how how ls works

How the fuck does LS work

As in the system calls / mlibc sysdeps

For tmpfs I’d probably store an inode that’s a directory that points to data blocks that have data

And then my data blocks would be a bunch of pages from the PMM for a file and will be contiguous if possible

But il have a seperate linked list to store those said pages

So for now it will be bad

But later it can grab 2mb blocks at a time

And then string those together

And then that will use the normal heapy heap

And il probably do an uhh slab of many orders

But il store free data right before the pointer I give

So a 512 byte order is more 528

But ehhh

Worth it imo

[hazy saddle]

This seem reasonable?

And then I could do a hashmap for file names to “inodes” or whatever

Not sure exactly where to store the inode numbers or how to index them or whatever shit

String into hashmap = inode

And that’s a regular array that’s resizable or some shit

[urban mulch]

You should strongly consider personally gate-keeping who gets to register.

You don't want some internet rando asshat to join and upload 5TiB of illegal content

[hazy saddle]

Should I add manual approval after signing up?

[urban mulch]

Fore sure

I know I wouldn't want to risk letting internet randos access an effectively unmoderated service I host

[hazy saddle]

What’s the config thing for that again?

Or I can go look on that thing but the document is fucking ass

[hazy saddle]

but I would be moderating jt atleast the bare minimum

Why can’t I have both

Make random people need an email before me approving them

Okay I can make them default restricted

“DEFAULT_USER_IS_RESTRICTED: false: Give new users restricted permissions by default.”

I cant find any info on what the fuck that means though

[hazy saddle]

It literally locks down the account more than users with no account

@urban mulch what exactly do you propose I should do here

[urban mulch]

Just do MANUAL_CONFIRM then

[soft snow]

what is this lol

[hazy saddle]

Guess I can’t be fancy with email stuff

[hazy saddle]

Forgejo

[hazy saddle]

I guess it’s still
Good for password resets

[soft snow]

You're hosting your own version of forgejo?

[hazy saddle]

Why not

I thought I could open it up but they seem to have stupid config options

[hazy saddle]

Wait big brain idea @soft snow

For my tmpfs

Il just use ext2

https://tenor.com/view/gif-gif-9403556598434283568

And then il have a generic rambd

Which will be allocated with like 32mb of ram or some shit

Or based on the initramfs

Then that gets unloaded into the ext2

Which is ontop of ram block device

And it’s all 4kb blocks because paging or some shit

And then that same ext2 driver

Will work on everything else I may or may not need

And then I have a really solid filesystem

[hazy saddle]

welp time to do reading

[soft snow]

huh what is this dude on

[hazy saddle]

what

[soft snow]

Never heard anything like it

[hazy saddle]

i mean its smart no?

and the rambd can use a radix tree similar to paging tables

[cyan bison]

not exactly the most conventional initrd formatt

[hazy saddle]

but it sure should work

and it kills two birds with one stone

and its readable and writeable

it also means i cant horrible fuck up designing a tmpfs

because https://www.nongnu.org/ext2-doc/ext2.pdf

[hazy saddle]

is there anything wrong with this though?

Plus it means I could technically put any filesystem ontop of the other driver? So you could allocate tmpfs devices easy and then treat them exactly like a disk in userspace too

[cyan bison]

idk it's just not an fs that you can easily generate

[hazy saddle]

I mean it’s also not horribly hard

And I need to be able to have ext2 drivers anyways later

[hazy saddle]

Wouldn’t it not be make the super block and other starting structures and then read the tar file and then create the files and folders as needed?

[hazy saddle]

makin a file to hold all macros

will replace them elsewhere as needed

[urban mulch]

This is a bad idea imo

It will break your separation of concerns

[hazy saddle]

for tiny little macros?

my utils folder is the junk drawer of the kernel

[urban mulch]

You'll end up with a single file concerned with too many things not related to each other.

[urban mulch]

You can already see it is wrong because you have both alignment helpers and logging in one file

[hazy saddle]

maybe i can have utils/macros/logging and utils/macros/alignment

[urban mulch]

no, just put the macros in the header files that define the relevant things

So log macros in your log header files

[hazy saddle]

i dont have one

i could put the log ones in my stdio file

[urban mulch]

💀

[hazy saddle]

this is for misc macros lmao

and id be movin them properly later

when needed

[hazy saddle]

bug patched

and confirmed workin

let me validate and push this

this has the seriel + ps/2 + tsc patches

shit i need to update the readme

waow i fixed it

it properly says you need clang

[rotund furnace]

Nix fixes this btw

[hazy saddle]

shut up

should i fucking bundle a nix package config file

[rotund furnace]

Yes

Because nix is better

[hazy saddle]

talk cheap send patches?

[rotund furnace]

I don’t use nix enough to write coherent configs :/

[hazy saddle]

i never said they had to be good

[rotund furnace]

Ah then

[hazy saddle]

it just has to spin up compile GCC and the kernel and spit out an iso

so people who wana use the kernel can do it easily

and get like reproducable iso hashes

[rotund furnace]

download stuff = yes
Build kernel = very good
Run = very good
Lag = none
Build time = short
Bugs = no

There is config

[hazy saddle]

thank you for patches

can you also make my kernel = better than linux

pls

[hazy saddle]

@rotund furnace Can you also put the parameter
popularity = > windows
Pls

Thank you for patches

Really backs up the talk

[hazy saddle]

I’m getting side tracked

I’m making proper implementations of shit

Because that hex to u64 function is dumb and stupid

Making ones that are like

Properly C compliant mostly sorta not really

But like still better

[hazy saddle]

@rotund furnace the VMM rb tree stuff should work on any memory map right not just the one right

wana make sure im not high

where each CR3 has its own rbtree for its mappings for user processes

and my kernel ones all use the main one thatl just manager the upper part

[rotund furnace]

hm?

[hazy saddle]

like every process should have the VMM instace stuff

[rotund furnace]

yeah

I do that

[hazy saddle]

and that also tracks allocations in general too? which makes freeing better

right?

[rotund furnace]

each address space has a vmm which has the rb tree root

[hazy saddle]

yes yes
