Kvass (vibecoden't)

[ocean ore]

yall if i have to ban kvass in california or colorado i will do so lololol move out

idk these laws suck BALLS

i ean nobody cares but like

this crap is risky

honestly

we can't fight back

nobody cares enough to

you have all your conveniences already - they're not gonna enter your country, and then they enter your country

you complain a little

a little group complains a little

a little group complains a little about a big group who does a LOT

you cant persecute someone you are under control of

one button and all of your friends are as if they were dead

one button and your house is raided

ONE SINGLE BUTTON and YOU WILL DIE

people claim the politicians simply dont understand technology

oh believe me they do

they know enough that most people will be trapped under their ideology

they know that everyone is gonna bow down to their laws since they are afraid to fight back

you all activists are just as afraid - where are you outside protesting about this?

or you cant

hm

are the activists all teenagers

if they are not an adult thats the only excuse i can make up

no way

WHERE ARE ALL OF YOU WHAT ARE YOU DOING

[ocean ore]

"oh oh! they dont know what linux is! they don't know how it is organized!"

start banning every distro lest the ones they approve

ban the source code

theyre gonna approve rhel, theyre gonna approve fedora, just as long as they have their possibly orwellian age practices

all linux distros are uncensored and available! It's just that some of them are more available than others!

[ocean ore]

wait its that mentality again

"someone else will do it"

come to terms - if you accept that no one will do it then someone will do it

if the opposite, then nobody will do it

its gonns get worse anyway i feel it

cant criticize someone under their own platform

sadly i forgot to include myself too

nobody wants to bother

this is the end of the line

one more day and this is 1984

actually nvm im of the opinion that california has brain damage

wasnt there a law that requires to recognize all gun patterns for 3d printer

i hope this monstrocity stays in california (also refered to as the layer of "greed" ) and never gets out

[ocean ore]

ok so thats enough ultra krill

gregloader

[ocean ore]

bruh so open fartware sucks a bit at putting crap into virtual memory

it maps basically one less page than what i tell it to

i tell it to map "1 byte" (yes the map function is in bytes) but it actually rounds down so it allocates 0 pages

WHAT

like excuse me

[ocean ore]

paging

today i will get to learn if my understanding of fartpc paging is correct

these numbers are completely random

(they SHOULD be random, these are supposed to be id's used for hashing)

[astral pagoda]

damn

[ocean ore]

ok so when i get home im writing a bunch of page table functions (map, unmap, etc) that basically pretend to be the cpu

they search the table like the cpu does

including all the hash bullcrap

i might have a mmu_page_t struct that is used for reference for loading and unloading pages (possibly multiple of them)

uint32_t startPhys;
uint32_t startVirt;
uint32_t size; // in pages

uint8_t  allowSupervisor : 1;
uint8_t  allowUser : 1;
uint8_t  allowExecution : 1;
uint8_t  userWritable : 1;

all powerpcs have the "do not allow execution" bit

BEFORE x86 made it cool

man porting this to x86 might mean sacrificing a bit of security but whatever

[tough garden]

what the fuck was ibm smoking

[ocean ore]

hash map

[raw prairie]

wdym?

[ocean ore]

no execute disable on some cpu's

[raw prairie]

dont support thoes CPUs

[ocean ore]

i mean core 2 duo and newer would make sense to support, i guess

[ocean ore]

fair

[ocean ore]

insane port - powerpc 32 bit to x86-64

[raw prairie]

i mean all x86-64 CPUs should have it

[ocean ore]

i mean i should consider doing ppc64

[raw prairie]

unless disabled in bios

[ocean ore]

or risc-v 64 bit

[raw prairie]

do loongarch64

[ocean ore]

brah

[raw prairie]

https://tenor.com/view/social-credit-credit-social-уважение-плюс-уважение-gif-1626328442317885176

[ocean ore]

risc-v is the logical conclusion to this ngl

powerpc 64 makes the most sense after this one tho

qemu is highly drugged so im not sure about emulation accuracy

[tough socket]

excellent vaguely sinophobic reddit meme

[raw prairie]

x86-64 so you can use KVM

[tough socket]

x86 didnt make it cool it was the very last one to get it

x86 was lame!

[ocean ore]

saying intel is lame is MY thing

[tough socket]

by like years and years too

[ocean ore]

haha fico score

i remember your rant about this

i think

but anyway idk which cpu would make sense to move this ordeal to 64 bit, naturally powerpc 64 bit would work

except i dont have a powermac and i dont trust qemu to work that much fine with it

i have an ibook but thats a 32 bit so i can use qemu 32 bit fine

if it explodes on real hardware at least i HAVE real hardware

risc-v qemu is probably well done since open source architecture or whatever

so im thinking of moving this to risc-v 64 bit if im doing 64 bit

[ocean ore]

idk which one was first really

im certain all powerpc's have the stupid no execute bit

of some form

so i assume POWER machines also do

[raw prairie]

wait @tough socket i never noticed that you have IRLQs in your name

im about to have to implement them for my debugging stub to work proper

[ocean ore]

i apologize for the off topic but wikipedia is genuinely insane

i think it might have info on the apple desktop bus

[raw prairie]

x86-64 qemu is also really well done. and allows easy irl hardware

• there is WAYYY less fragmentation lol

[ocean ore]

(apple's evil PS/2 ripoff)

[ocean ore]

true ig

[raw prairie]

so if you get over the hurdles it will run on everything

[raw prairie]

they have everything

[ocean ore]

everything

[tough socket]

wow... u got the order wrong again....

ADB is from like 1984

PS/2 is from later

99% sure

[ocean ore]

ok true

[tough socket]

in any case no chance they could have known about PS/2

[ocean ore]

ADB is 1986 and ps/2 is 1987 ig

but still tho

they came out around the same time

[tough socket]

im probably the ultimate reason u know about irqls

[raw prairie]

nah that was obberow

my plan is to add IRQLs so my serial can be at IRQL15 and my debugger can set it to IRQL14 when waiting for serial to tell it things

what way i can pause the CPU properly without the cursed AF NMI crap

[ocean ore]

irql 17

[raw prairie]

Thats illegal

[ocean ore]

nobody still knows what IRQL_LESS_OR_EQUAL means

[ocean ore]

in what country ok fair

[tough socket]

why do you think he knows about them?

[ocean ore]

maybe he does

did he implement them

[tough socket]

its because ive been shilling NT features since like 2020

[raw prairie]

He added IRQLs to his kernel and to prism

[tough socket]

nobody here knew jack about it before that

[tough socket]

im saying he knows about them cuz of me

he learned it from me

[raw prairie]

Oh lmfaoooo

[tough socket]

whats prism

[raw prairie]

Well IRQLs look like the perfect solution to my problem don’t they?

[raw prairie]

Kernel project in C++ between a few other people that’s sort of in stasis rn

[ocean ore]

ah yes prism

the dead project

https://tenor.com/view/drunk-gif-14188478439184360954

[raw prairie]

It’s not dead

Fully

[ocean ore]

so much for linux compat

[ocean ore]

CEO of IRQLs

[raw prairie]

But yeah @tough socket could I ask you about IRQLs more later so you can shill them to me when I try and implement them lol

Because from the little I see

They are very kool

[ocean ore]

im gonna go utterly insane if someone tries to do a powerpc os because i did it

actually, nobody can survive the paging for some reason

you need to reach nirvana before you can

[raw prairie]

Make an open source PPC paging library

[ocean ore]

i genuinely dont know why the people ive talked to are scared of the paging

[ocean ore]

how about "no"

[ocean ore]

my sticker 👍

i thus shall actually USE the diagram

be afraid mortals the shitposts are gonna become actually useful

[raw prairie]

I actually do wonder why mode kernels don’t use IRQLs

Will kvass support IRQLs

[ocean ore]

it is time

[ocean ore]

i havent studied interrupts that much yet but i dont have them i think

im thinnking of adding support for graphics cards and audio early on for some reason tho

maybe hard drive swap, my os is kinda designed to work on like 128 mb of ram

actually thinking about that

hard drive swap is schizophrenically insane

id rather make my powermac play ultrakill instead of this

[raw prairie]

No that’s normal

But like on 128mb ram

Your kernel won’t use nearly that much

Even on x86-32 a full TTY userspace is 32mb

For Linux*

[ocean ore]

risc jumpscare

[raw prairie]

So you should be fine

[ocean ore]

idk i actually have 384 mb on my ibook

but some ibooks shipped with like 128 or 256

or worse

[raw prairie]

I mean that’s to be expected from Apple

A fucking 600 dollar laptop in 2026 with 8gb ram a worse processor than the iPhone because they stripped it down further. And it still has a USB 2 port and they placed it in a missleading spot

[ocean ore]

true

they did put normal amounts of ram tho

its not today's apple, they had braincells

[raw prairie]

[ocean ore]

i mean 256 mb of ram was FINE for their cheapest laptop probably

but anyways, behold, address

[raw prairie]

Honestly that laptop wouldn’t be bad if it was all usb 3.0 and had an option to get 16 or 24gb ram :p

Even if it bumped the price up to 700 and 800

[ocean ore]

ehhh i can live with usb-c as a macbook user

ok fine i dont use the ports for anything

[raw prairie]

No one usb c is 2.0 another is usb 3.0

And the port that you wana your your charger in

Is the 3.0 port

And 8gb ram is unacceptable

I want 24gb minimum on any laptop I get in the future

[ocean ore]

my address is now dissected by Machine(TM)

0xF1234ABC

[ocean ore]

bro what

aint that a crap ton

thats a crap ton

why you need so much

[raw prairie]

My desktop has 32gb ram :p

[ocean ore]

i have 16

[raw prairie]

24gb can be gotten with two 12gb ddr5 sticks in modern laptops

[ocean ore]

fire i guess

[ocean ore]

fair

but why do you need the dedotated wham

[raw prairie]

I play modded Minecraft and that can gobble up ran somtimes

I’ve had it OOM on my laptop with 16gb ram only having zram

[ocean ore]

zram?

also ive seen like two people say that they need gigatons of ram to play modded minecraft

cope, it works fine on my machine

[raw prairie]

zram is compressed ram for swap

[raw prairie]

INB4 needing to allocate 12gb to it and run discord in the background and a YouTube and using an iGPU

[ocean ore]

yall i just realized

this is utterly psychotic

this paging sucks balls

beyond human comprehension

[ocean ore]

hash

wait no this might be wrong

[frigid basin]

change all of them to 0x8008135

[raw prairie]

if you like XOR. why not use more XORs for your rng

[ocean ore]

[ocean ore]

i have to use xor's because CPU

[raw prairie]

Yes

But use more XORs

[ocean ore]

yis

i thought of a scary pmm idea but i think i just realized how to make a buddy allocator

or not

how do these work again

wait

hash map pmm /hugej

[muted talon]

brotato

when you will port kvass on x86

use clamboot as a bootloader

(it will be done already probably)

[ocean ore]

idk

also can someone send me a huge text wall on how buddy allocators work

please speed im interested my brain is kinda empty

[muted talon]

that was not a question

[ocean ore]

i ask and i dont receive

🔥 🔥 🔥 🔥 🔥 🔥

anyway

yall i genuinely dont understand them

send help

ykw im just gonna do my alloc idea when the time comes

its gonna be the best alloc - utter magnificence /j

[raw prairie]

Why not use a freelist

Then for devices use scatter gather DMA

Iirc NT does this

[ocean ore]

aint those like fragmented to death ~~even though ive already written one with an algorithm to solve the fragment issues ~~

[raw prairie]

Yeah but if you don’t need contiguous memory

Your fine

[ocean ore]

whats that

[raw prairie]

That’s the point of paging

So you can have fragmented physical memory

But contiguous virtual

[ocean ore]

long slabs of memory??

or whut

[raw prairie]

Like two pages that meet up

[ocean ore]

[raw prairie]

Like 0x0000 and 0x1000 and 0x2000

That’s contagious

Contiguous

[ocean ore]

if two pages meet up theyre being merged

im willing to dig through the entire freelist every time i alloc MUAHAHAHAHAHABAHAHAHAHAB

still faster than a bitmap

[raw prairie]

You don’t need contiguous pages that’s the point

That’s why a freelist is fine ;p

[ocean ore]

whatever

fine ima freelist

i need my paging implementation first

im afraid im doing it wrong because ppc is insanity

[raw prairie]

https://tenor.com/view/family-guy-whip-angry-dad-gif-15082707

Power pc paging be like

[raw prairie]

You either go insane or the computer does

[ocean ore]

nah i went insane already

i walked so i could run

[raw prairie]

Crazy?

https://tenor.com/view/crazy-rubber-room-gif-10524477174166992043

[ocean ore]

crazy?

i was crazy once

they locked me in a room

a rubber room

a rubber room with hash maps

and hash maps

they make me crazy

[muted talon]

✋

[ocean ore]

[tough socket]

The point of a page free list is that you don't merge them

It's just a list of page frames

That you can pop and push items from

[ocean ore]

true

honestly sure with the freelist crap but like i still want to know how buddy allocators actually work

ive heard several explanations

i understood none

[tough socket]

Have you looked at ancient XNU releases for hints on how to do PPC paging

Amit Singh's book Mac OS X Internals is from like 2004 and describes how they use paging on PPC

[ocean ore]

nah im just reading the manual

[ocean ore]

cool

[ocean ore]

its tolerable

explains a bunch of crap

[tough socket]

You definitely want to read about how a real kernel used the paging hardware

[ocean ore]

maybe idk

honestly true i guess

apple devs might have a bit more braincells

[tough socket]

I'm somewhat stunned you haven't already looked there

Getting to empathize with other kernel devs who had to figure out the same shit you are is like one of the most satisfying ways to learn things like this

[ocean ore]

true true

i did use the mac os x bootIoader for some reference of navigating open firmware's calls

til the 256 color palettes use 24 bit colors for reference

im thinking of feeding the palette rgb stuff instead of a bunch of grays like the mac people did

i need to convert 8-8-8 rgb to 3-3-2 rgb or whatever tho

i have an idea for an allocator but im worried the allocation crap might require a few gigabytes

for 128 mb

actually wait if i redo it a little i can have a reasonable pmm

[ocean ore]

"it will suck balls indeed", as stated in the DELTARUNE prophecy

[ocean ore]

basically behold, my idea in the worst format possible

big array

if i reinvented something dont crucify me

im thinking of having smaller arrays instead of one big one

space saving on old hardware

[ocean ore]

ok so im just gonna have smaller arrays instead of one big one

hopefully

69420 tiers

this is literally a slightly faster bitmap

[wet barn]

trying to figure out what this means x3

[ocean ore]

i forgot too

[ocean ore]

i got blocked by some dude

whatever

so kvass

returning to this xor crap

idk i set my address to 0xFFFFFFFF

[raw prairie]

You know what an xor is right

[ocean ore]

0 , 0 = 0
1 , 0 = 1
0 , 1 = 1
1 , 1 = 0

[raw prairie]

Good

[ocean ore]

i just realize i can invert numbers with this

put a 0xFFFFFFFF mask over it

1s are 0 and 0s are 1s

[raw prairie]

if you xor a number with its self its zero

and thats faster than a mov

[ocean ore]

what 😭

[raw prairie]

but on x86 never do xor rax, rax

because its slower

somtimes

[ocean ore]

crap86

SOMETIMES

[raw prairie]

always do xor eax, eax which still clears the upper bits

and is always faster

[ocean ore]

How

who made this 😭

https://tenor.com/view/kjkeyspammingbelike-gif-20130186

anyways i should actually work on this

so i got the table hash

and i lost the diagram

and i need to find it again

[raw prairie]

well some CPUs gave a bug
and the eax version is smaller code size

[ocean ore]

oh

[raw prairie]

because you dont need the extra byte for 64bit code

[ocean ore]

intel microcode bugs go hard

do you remember the pentium M thing

[raw prairie]

and for 32bit compat. all operations with 32bit regissters zero the upper 32 bits of it. as they are the same as 64 bit ones

just a slice of it

16 bit registers dont do thus btw iirc

[ocean ore]

i wonder how did this go through their head

oops

idk they gotta have a testing suite

why didnt the pentium M crap have a PAE test

😭

[ocean ore]

https://tenor.com/view/folk-druski-sona-instagram-instagram-meme-gif-18271404859547050805

this is diarrhea

actually no wait this is ine

fine

probably

idk its less registers to waste

idk how this works on powerpc

i think the 32 registers are gonna actually become 16 registers

or not

no i dont think they do

its 32 registers

[raw prairie]

https://stackoverflow.com/questions/33666617/what-is-the-best-way-to-set-a-register-to-zero-in-x86-assembly-xor-mov-or-and

this is a great wruteup

[ocean ore]

insanity

i guess im gonna implement a NUM_ZERO macro and it uses it instead of mov

i hope

💀

[raw prairie]

GCC properly optimizes for this btw

Do not try and outsmart the compiler

[ocean ore]

oh

[ocean ore]

fair

anyways so currently i have to implement this part of the diagram™

[raw prairie]

Just if you go and write x86-64 assembly

[ocean ore]

THE diagram™

[raw prairie]

It’s somthing to keep in mind ;3

[ocean ore]

fair

[ocean ore]

so what is this and what is this for

wait

idk waht i said

what do i move into pteg addr

it looks like the top 3 of the first 9 bits are moved at preg and the rest of the 10 bits are grabbed

MOVED AT PREG

🔥🔥🔥🔥

surreal feeling when there are no new messages at the server

[ocean ore]

i did a lazy

i played crap ton of ultrakill

but anyway so ive got the bits the diagram wants from me

[ocean ore]

top 3 bits of the first 9 bits

then what do i have to do in the ritual here

best var name btw

idk what to call it

/gen

[ocean ore]

maybe HTABpt idk

way better than thing1 at least

got PTE number

utterly deranged i say

[ocean ore]

i forgot to send paging

i got my address together

have some binary crap no one can understand

👍

i need to replace FFFF with the actual pt address

my utoa sucks balls

aaaaaaaaaaaaaa

what if i evaporate and make a new account

no traces of my existence

idek

i have too much to just yeet it out the window

im just mildly pissed at an argument that happened today

yall shouldnt care, its just annoying that if im in a good mood something will HAVE to ruin it

venting in an os progress thread, it cant get any worse

anyways so maybe i should take a break from discord

[ocean ore]

seems like the person is holding a grudge against me too

which is sad but understandable

whatever i definitely should stop lamenting about that

you cant have everybody liking you

[ocean ore]

so here's the fart basically

my goal is to uhhh

turn that to a virtual address

also why did it change to 29828

what

where should powerpc pagetables be aligned at

i just wanna make sure

IM DOING MY CRAP WRONG

RRRRRAKUJHUQWB

[ocean ore]

HTABORG is 12 bits

i have to offset it 32-12 bits to the left

that is 20 bits for the mathematically impaired

binary number that i refuse to describe where

:(

THATS NOT THE ADDRESS

im tired boss 😭

fine im gonna lock in

this feels like terminal lucidity

actually this isnt even terminal lucidity anymore i feel dead

so the PT address is 16 bit long

[ocean ore]

what in the flying gigglefart is this table, then

they smoked something

if i discover something more stupid im gonna probably be able to guess how severe of a drug that was

so basically the HTABORG address is turned to 16 bit, 3 bits are cut off, its then shifted left by idk 20???

conclusion: the substances are illegal

i need to do this with the addresses they give me

"a door leading to " a bossfight room that happened at least 15 levels ago

"are we fighting a fraud of the boss" wrong, you're fighting his simps instead

but anyway im gonna go rewrite all me paging code

MUAHAHAHAHAHAHAH

[ocean ore]

my address has to be 64 kilograms aligned

no but like idk its wrong even with 128k alignment

how do i allocate memory for these darn tables

wait

wait wait wait

oh no

oh

they have to be 64k aligned

FOOL I ALIGNED THEM 128 K STOP COMPLAINING

i concluded i have to align them by 1 mib

https://cdn.discordapp.com/attachments/1398723862857781440/1453056521696051464/image.gif

no wait its 64 k again

[tough socket]

so somewhere between 10% and 100% of the remaining systems will bow

[ocean ore]

fair

[ocean ore]

im pretty sure its 64k

however the thing is that only the first 12 bits of the address are used in the actual pte search and the other 3 bits are pulled from the hash

which sounds correct, since if these 3 bits of the hash were somehow 0, it would be the start of the table

basically this is the address of the table and my small rant printed out

i wonder

i think it has to be an address way high up in memory

el this crap

so my question is that 0x23000 isnt a full 32 bit address

so the address looks like this???

so its 1 mb

the 1 mib alignment is so stupid because i only have 128 of these

i wonder what an OS with a non euclidean GUI would look like

[ocean ore]

these requests are gonna go INSANE if i align every slab of memory i allocate by 1 mb

memory map of doom 😭

but we have the concept of bootloader reclaimable ram for a reason

[ocean ore]

lemme check the crappagram of doom

im just gonna send it here

[ocean ore]

if its not 1 mib aligned, im just gonna align it by that because why not

"memory safety guys " - rust people

wait i have a better idea

allocate from the top of the memory map

its gonna solve the problem i hope

b e t t e r

yeah it should be 1 mib aligned

what if i just keep drafting memory until its address is more than 1 mb

just in general greater than 1 mib

because this paging sucks balls or something

wait

thats 64 kilobyte aligned

[ocean ore]

64 kib isnt fine since these top 3 bits get cooked

one more 0 boys

better

1 megabyte

i print the entire 32 bit number

its good for utility

i found the UltraSPARC spec

if the mmu doesnt suck balls again i might port my crap to that

maybe SPARC V8

currently i want a ppc64, SPARC V8 and UltraSPARC (V9) port

[ocean ore]

what if i make a CPU

i like the load-store system a lot

[ocean ore]

id have to like make some sort of compiler for it

hmmmm

a wise man once said, "I know a guy."

[ocean ore]

their compiler no have switch statements

im not elaborating on who

@raw prairie oh also did you upload the instruction manual of doom and evil

i am claculate pteg

final address (at least the 0xF980 part) matches

i have to OR it with the start of the thing now

i did the same addresses as in the example to make sure i had everything done right

now it matches the diagram

i did it

i saved the world

I SURVIVED POWERCRAP PAGING

i expected to be slightly more excited

whatever(TM)

wait

the htabmask

bruh it says its explicitly shown in the figure

the process of ANDing it with something

where

wait

WAIT WAIT IWAIT IWA

NO NO NO NO NO

NO

NO NO NO NONO

AAAAAAAAAAAAA

the number of bits in the HTABMASK determines how many bits are added to the left of bit 15

I AM NOT DONE WITH THIS I AM TRAPPED

AAAAAAAAAAAAAAAAAAAAAAAAA

i did it i calculatedeth the stupid paging

ima take a break and move my elf parser so i can reuse it in my kernel later

[tough garden]

PowerShit™

[ocean ore]

PowerWASH my braincells

dudududududududdudududududuudud

whombwhombwghombhwomhb

anyways im making a cpu architecture for some reason

load/store risc and all

[tough garden]

make it 128 bit

[ocean ore]

i want to give it SANE paging that wont make me want to kill myself

[ocean ore]

violent

[whole heath]

pagemification

[tough garden]

247 bit paging

[ocean ore]

im giving it 256 registers

MUAHAHAHAHAHAHAHAH

[tough garden]

literally itanium

[ocean ore]

least psychotic itanium ripoff

i mean itanium is weird honestly

[tough garden]

give it 8.3 registers

[ocean ore]

what 😭

[tough garden]

give it .3 of a register

[ocean ore]

but why

[tough garden]

because I said so

[ocean ore]

i did another funny, the jump instruction has a register input

you jump to a location in a register

[whole heath]

That's not weird at all

[tough garden]

actually can x86 not do that

[ocean ore]

idk

[whole heath]

x86 can do that

[ocean ore]

i thought you usually jump to a memory address

[whole heath]

Literally every arch can do this

[whole heath]

BRO HAVE YOU EVEN HEARD OF FUNCTION POINTERS?

[ocean ore]

yes

[whole heath]

Those work with jump to register

[ocean ore]

caps lock abuse

fair enough

i mean my thing with the jump on register is that you have to pull the address from another memory location

you cant just move it into the register with a move instruction, the move instruction only moves from a register to another register

[whole heath]

What

Why have jump **register but not jump *register

[ocean ore]

[whole heath]

You do realize this is going to make it super hard to get support on mainstream C compilers right?

[ocean ore]

fair

fine im gonna make move move numbers in the binary into a register

idk move r0, 0xC0000000 is valid now

[whole heath]

This just sounds like you're creating an intentionally unusable and esoteric arch

[ocean ore]

nah id say its quite tolerable

currently only 22 instructions

[whole heath]

If I had to guess you don't design CPUs as a hobby whereas I do

[ocean ore]

no wait its 23, including halt

[whole heath]

And I'm telling you from what I've learned this is all sorts of bad ideas

[ocean ore]

i dont think i design OSs as a hobby either

now i do but like

[ocean ore]

fair enough

ok honestly some of this design sucks balls

half the instructions require you to use numbers in registers when they could very well just use regular numbers

actually nevermind no CPU

kernel time, again

https://tenor.com/view/500-ciggarettes-gif-11805300176740010737

[raw prairie]

500 side projects

[ocean ore]

ok so my powercrap is gonna now be actually used in the real world(TM)

if it dies, im gonna go insane

[ocean ore]

powerpc64 paging has an upgrade to be even MORE psychotic

i have to somehow put the size of the table into the storage register and then i have to decode it into a mask during translation or whatever

BUT WHY, THE MASKS ARE THE SAME

not just that, plus a bonus of the fact that i never worked on 64 bit addressing ever

its not gonna be bad, its just intimidating and im gonna go insane comparing my crap with whatever diagram

yall the diagram is even more concerning

thisi s "the diagram" in full 64 bit glory

this is utterly OUTRAGEOUS

holy crap its more vague too

The low-order 17 bits of hash value 1 are then concatenated with the high-order 40 bits of HTABORG and with seven low-order 0 bits, defining the address of the primary PTEG (0x0F05_8400_0F3F_F300).
AAAAAAAAAAA

wait

no

nvm i thought this was the intended form of the cpu as well

generational level crash out avoided

or delayed until i find out

you have the option of a page table taking 70368744177664 bytes on 64 bit tho

sure that may sound large

except its way larger than you think

THAT IS 64 TERRABYTES

"future proof architecture" indeed 💔 🥀

they should use powerpc for data centers

i feel like this is the only arch that can comprehend this much ram

ok so i did more accurate testing on my powerwasher paging

i think i dislike this crap enough to start calling "powerpc" a "powerwasher"

im thinkong of making a powerpc64 port of the bootloader as soon as i get a test kernel booted

thinkong

[ocean ore]

the paging is HEAVILY intriguing

its probably the same other than the diagrams sucking even more balls and it having another additional section of this CBT ritual

yes the diagrams have explanations

they just suck tho

[ocean ore]

ok so my goal once i boot a test kernel fine is to actually make a powerpc64 port of this bootloader

with funny paging again

i should genuinely consider doing a SPARC port of this

no idea if it would run on a real sun machine

whatever

[ocean ore]

also 68k

im usually now a RISC shill but people put the 68k in high regard

im pretty sure i cant do it on a 68k macintosh machine yet, however i think qemu has a firmware

kvass for NeXT workstations

might fit actually, ive noticed my computer choice is all fancy workstations

sparc, 64 bit powerpc

the only home one is 32 bit ppc

[tough socket]

sparc is another one with a weird mmu

[ocean ore]

ik

at least V9

[ocean ore]

i only checked a really small part of ultrasparc's manual

the mmu would be anything if i understood the manual in the first place

i figured out the powerpc one so idk how sparc v8's or ultrasparc's manuals are gonna be bad

[ocean ore]

sparc is utterly insane compressing their manuals in *.gz's

pdf.gz

a normal unix/linux machine would open it but not my android phone

[ocean ore]

you need to pay sparc international $99 to produce a SPARC processor

their blog last posted in 2020

it feels like a website from like 2013

its giving me the same vibes as the java installer for windows does

https://sparc.org/technical-documents/

US$99 for a keyboard license 😭

thats the same as the rest of the ISA

What a steal!

The SPARC ISA does not mandate that a single MMU design be used for all system implementations. Rather, designers are free to use the MMU that is most appropriate for their application — or no MMU at all, if they wish.
THATS THE BEST MMU!!!

NO MMU!!!

what does qemu implement

supports sun4m fully

its some workstation i guess

sun 4

russian (idk why its russian) wikipedia says sun 4m is intended to be a multiprocessor version

[ocean ore]

would it be reasonable to assume it uses whatever "reference MMU" is mentioned in that manual

[tough socket]

i have a 32 bit sparc workstation

and a 64 bit one

i put nextstep 3.3 on the 32 bit one

its a sparcstation 20

[ocean ore]

rich

[ocean ore]

richer

[ocean ore]

mk

[tough socket]

i found it in my dad's basement

he had taken them home from work in 1997

and forgot about them

until i found them

they still worked

[ocean ore]

have you ever put linux on it before NS

i want to check what mmu it actually uses and if i need to dig it out from the depths of the internet

[ocean ore]

menacing

[ocean ore]

im convinced it uses the like "reference MMU" or whatever

[tough socket]

u could look up linux sources

and see how it manages the mmu

on sparc

[ocean ore]

true ig

i hope there isnt a kiloton of these stupid sparc machines with like 50 various mmu's

[ocean ore]

it uses something called the "SRMMU" which after checking is that reference MMU the SPARC v8 manual mentions

[gloomy mist]

proprietary

[ocean ore]

sparc intenrnanationlf

[gloomy mist]

I had a few sparc boxes back in the day

[ocean ore]

interesting

what was the experience

[ocean ore]

also you indeed purchase the keyboard spec for US$99

idk why not the rest of the ISA

[raw prairie]

It’s a very fancy keyboard

[ocean ore]

a license to the rest of the SPARC isa also is $99

[raw prairie]

Can you believe how much work they put into that keyboard smh

[gloomy mist]

I had two of these https://www.ebay.co.uk/itm/313015989146

[raw prairie]

It’s almost harder than making an entire ISA

[ocean ore]

25000 dollar workstation, keyboard costs 29999

[gloomy mist]

and one of these.... brb finding

[ocean ore]

well this looks like a server

UltraSPARC

[ocean ore]

yeah it might actually be

the bugs manufacturers have with PS/2 are sometimes outrageous

[gloomy mist]

I had sun storedge 3300 fibrechannel

I can't find a pic of it

basically the t1s and the storedge were part of an enterprise redundant failover

free from an old workplace

[ocean ore]

maybe its called something else outside of the UK

[gloomy mist]

but I got rid, they were too expensive to maintain and at the time had no 2nd hand value

[ocean ore]

the only pictures i could find are of a weird box with a funny purple front panel

[ocean ore]

ohok

scary UNIX moment

[gloomy mist]

there's a pic

it weighed 60lbs without drives

I didn't drive at the time had to haul it to a train station

serious big iron

[ocean ore]

it looks like such

this plastic thing holding it up says too much about it

looks like its made of like steel or something

[gloomy mist]

that's not part of it, that's for taking product photo

it is solid metal casing

I cut myself sliding the top off

had to buy a ton of fibrechannel SCSI to run it, and I still couldn't configure it

I think it needed a smart card with a license on it to boot

[ocean ore]

yoooo its good paging again

[gloomy mist]

the t1s had a smart card in the front for their boot code, was weird

[ocean ore]

oof

[ocean ore]

long time no see

[ocean ore]

idk what smart cards are

Welcome to OpenBIOS v.1.0.1

Please insert a valid credit card to continue system start-up...

[gloomy mist]

look up javacard

[ocean ore]

oh

[gloomy mist]

it's like chip and pin debit cards but instead of bank details they hold openboot code and digital certs

[ocean ore]

ohok its the stupid password chips

[ocean ore]

fair enough

this feels unnecessary on one hand

but like, its quite secure otherwise

[gloomy mist]

it was called a system config card

[ocean ore]

this looks like one of those doom keys except grey

[gloomy mist]

you need the grey key

[ocean ore]

E1M1 should be renamed to "open firmware card search party"

idek what the SPARC workstation and powermac firmware is even called

qemu has "openbios", macs have "open firmware", there's also "openboot"

[gloomy mist]

sparc was openboot firmware

idk what was open about it

[tough socket]

it was an open standard which got adopted by IBM and Apple

[gloomy mist]

ah

[ocean ore]

its an IEEE standard idek

was

[barren sierra]

do you have interest in porting mintia2 to this machine someday? I would port my own OS to it if I had one

[ocean ore]

im honestly thinking of porting my os to xrstation for the funny

honestly the worst part of my idea is that i dont even own a sparc workstation, sadly

nor a ppc64 computer

im pretty sure some dude is willing to test it on ppc64 but either way

[barren sierra]

I was considering the same thing, now with monkuous' xr17032 gcc it's possible

[ocean ore]

fair

[barren sierra]

you can port to arm :)

[ocean ore]

ARM is everywhere

theres like a trillion versions of that though

theyre probably the same ISA but intended for different versions of experimental CIA supertorture railcannons

"supertorture railcannon" actually sounds scary ngl

anyway tho

currently im gonna be reading about the (i'd say) saner part of powerpc paging

and implementing, of course

there are PTEGs, they are searched after determining the hash

the hash calculation is the stupid part

[ocean ore]

PTEGs have 8 page table entries

however there is a second hash

thankfully, for my own sanity, the second hash is an xor of the first one by 0xFFFFFFFF

[ocean ore]

basically, a hash can get you two PTEGs

this exists for accounting for hash collisions,

uhhhhh

yeah

16 entries per hash

they have no funny schemes which involve searching them, they're just searched consecutively

it also mandates every PTE has the VSID

of uhhhh

idk segment register???

probably the vsid of the segment register which lead to that entry

my MMU implementation should skip all enabled entries and stop at the first disabled one

i like the motorola docs, except this is a bit evil

why cant you have normal page numbers :(

i remember that "The Diagram" is located at 373 i think

that is 7-80 something

ight found it

V = valid, H = no idea, API = EVIL crap, RPN = physical address??? R = uhhh, C = changed, WIMG = 4 bits that set protection stuff, and PP is protection combinations of some sort

from what i remember

id say a bit field will be fine for this

two, its 2 32 bit numbers

well this is better

whats an API

abbreviated what how

[ocean ore]

im gonna consider compiling sparc and ppc64 gcc and binutils

i assume powerpc64 would be powerpc64-elf-gcc

sparc is probably sparc-elf-gcc

but sparc64 is either in sparc-elf-gcc or its in like sparc64-elf-gcc or something

its in sparc-elf-gcc it seems

-mcpu=v9 is 64 bit

-mcpu=v7 is for mentally disabled people and -mcpu=v8 is 32 bit

[frigid basin]

unrelated but would u recommend osdev to a normal person

[ocean ore]

unless theyre interested in that crap and arent 10 years old then no

[ocean ore]

c++ looks really cool, im thinking of writing my kernel in it

link it with some C stuff to avoid me crashing out

im probably gonna write it like c with classes and namespaces

i like C a lot, im not gonna completely enter circus mode

what im definitely writing in C is the boot function which sets up PMMs and such so i get new operator

[ocean ore]

and also my mmu implementation is in C

its gonna be stolen from gregloader

im just gonna port it on c++ honestly

idk c++ just looks cool, ive never made anything in it tho

[ocean ore]

nevermind c++ might be dum kernel level

genuinely dont know

its pretty cool here but like

idk

i met a bunch of cool people here but honestly im not sure if i care

im thinking of simply avoiding lounge 0 like the plague, no matter how much i liked it

that place is actually brainfart inducing

also im thinking of localizing everything into russian or whatever

like the stuff i have

it sounds pointless but either way though

:/

https://klipy.com/gifs/sonic-wave-gd

anyways so bootloader has full paging implementation and such

[ocean ore]

what if i just drop all english crap and make my os be basically fully russian except the C code

powerpc OS in russian, this is truly gatekeeping of all time
