The Flopperating System (tfos) - x86 32 bit Hobby OS

[bold grove]

i had alotof bloat in my old scheduler

[bold grove]

smp is done

well

the code writing is done

time to test

[bold grove]

IT WORKS

SMP WORKS

I RAN FUNCTIONS FROM EACH CPU

AHEJNEIDENNDDKEN

CUM

EVERYWHERE

SORRY FOR TMI

[warm pasture]

poggggg!!!!

[warm pasture]

now do gsbase-based percpu data

[bold grove]

That’s what I’m doing

[warm pasture]

daang

[bold grove]

It’ll be on the repo soon

I shoved my entire apic shit into my interrupts file

[bold grove]

I have a cpu control block for each cpu and I’m using gs for that

So my get_cpu_control_block just accesses gs

[warm pasture]

its pretty cool that u get shit done pretty fast
ive been doing memory setup for months 🙏

[warm pasture]

cool shit

[bold grove]

Redbull + boredom

[bold grove]

What have you been setting up

It took me literally months to do my mem subsystem so don’t feel bad

I got rid of bloat in my vmm today

[warm pasture]

I have both yet I dont do shit
im dumdum ✨

[bold grove]

My mem subsystem is still like

Not great

Man I haven’t updated the repo in a fat min

5 days ago

I need to lock in

[warm pasture]

okay well thia actually made me feel better lmao
I got pmm hacked up
slabs + magazines for heap are mostly done
and working on vmem and the higher level interface fir memory objects etc (still mostly wip)
aside from that everything else is just code snippets scattered all over the place 😭

[bold grove]

Yeah vmem is fucked

[warm pasture]

rip
I push all commits once theyre out cuz I gotta collect all them gh activity squares

[bold grove]

I have an issue with wanting perfection

I want a perfect x86 kernel

[warm pasture]

tbh its more like the way im doing them is mostly even more fucked 😭 😭

[warm pasture]

nah i cant dream of that here

but like ur kernel is actually super cool

with floppa as a mascot being the cherry on top

[eager badge]

i feel your pain. wanting a perfect system has held me back so much

i did linux from scratch with no internet link at all. does that count? 😅 it was easier back then -- 2001

[bold grove]

Like I’m wasting time perfecting things

[eager badge]

yeah

[bold grove]

I fucking hate court hearings

I’ve been sitting in a fucking room for 2 hours and they’re not even close to me

Fuck my LIFE

[gray cairn]

insane, was i crazy to implement a 821 line MLFQ 😭 PerCPU

[cobalt nebula]

my CFS is 600loc, and its just for calculating a number

the process creation itself is another 1000 loc

not to mention other scheduling classes

[gray cairn]

same, threads and my processes take almost 1000loc EACH

[azure rapids]

that's kinda crazy

threads, processes and my whole scheduler doesn't even TOUCH 1000loc

including arch deps

[cobalt nebula]

more doesnt mean better though

[bold grove]

That’s just the core functionality tho

Now that I’m adding shit it’s back to 1000

And my process stuff is 1k

[paper cloak]

i have a semi-good ULE clone in around ~900 lines

[ivory blade]

grahpical terminal

[static tartan]

we had fah
now we have grah 😔

[hasty anchor]

Same

[violet anchor]

what's wrong with that lol

[radiant grove]

idk

[violet anchor]

apart from they should probably be static inline

[violet anchor]

not a grahpical treminal?

[radiant grove]

grahpical

[violet anchor]

greppical terminal - you gotta use the command line tools to read wtf is going off lol

[radiant grove]

https://tenor.com/view/rocket-greenscreen-gif-5649293510147604779

boom

[bold grove]

So apparently I have diabetes

I’ve been having these episodes of just crashing and passing out anywhere and I went to the doctor they did some tests and figured out I have type 2 diabetes

[bold grove]

Smp is tested and working

I can load the Flopperating on 8 cores

[azure rapids]

nice!

[radiant grove]

holy crap lois

[bold grove]

Okay so

Kernel name - Flopperate or Flopperating
Os name - the Flopperating System

[eager badge]

kernel name floop

[ivory blade]

floppernel

[eager badge]

sound subsystem: floppera. flopera. whichever

[violet anchor]

flernel

[gray cairn]

floppwire
floppplumber

[violet anchor]

fwub fwub fwub

[warm pasture]

floppinit
flosh
flopkg

[static tartan]

flosh?

[warm pasture]

[eager badge]

dying laughing at "flosh" 🤣

floppplumber reminds me of plan 9's plumber, which is one thing of plan 9's i would immitate. it isn't anything to do with sound, it's essentially the file association handler, but it's programmable and can take arbitrary strings such as man page references

[bold grove]

Seems like the name “Flopperate” is winning

[radiant grove]

call it Ядро Операционной Системой "Floppa"™

kernelo operationnio systemio floppio for spanish users 👍

[bold grove]

Језгро оперативног система “Floppa”™

[radiant grove]

call it that lololol

[bold grove]

Hey guys

I was planning on releasing the smp version but I’m just having a rough night

I’ll try to get it out this week

Good night fellas

[blissful grove]

night man, rest well 💤

[final wyvern]

have a good DREAM

[bold grove]

Been taking a little break.

Will update you guys soon. Have a good night

[bold grove]

The smp update completely fucked my entire code base so I’ve lost motivation

[bold grove]

I might make a new OS

[azure rapids]

maybe this time make it for x86_64 :P

rip smp tho

implementing smp as soon as you can make everything less hell

[bold grove]

that’s the idea

[bold grove]

I’ll just use the limine mp request

[azure rapids]

that also works

[azure rapids]

it's really easy (ty mint)

[bold grove]

Okay sounds good

I’ll actually port a stdlib this time

I think imma name it the Advanced Flopperating System

And nake the kernel name Flopperate

[radiant grove]

powerpc64

[warm pasture]

sadge

perhaps roll it back and give it more thought
then try it again

just dropping the floppa is so 💔

end of an era fr
but perhaps 64bit is worth the sacrifice

[radiant grove]

dont worry the floppa is gonna be resurrected after 3 days

[azure rapids]

floppa was killed but in 3 days it came back 🔥

[warm pasture]

floppa came back from the dead and we are all witnesses of it

[bold grove]

NVM FLOPPAOS WILL CONTINUE

I GOT MOTIVATION

well fuck

gpf

[bold grove]

Still getting gpf

Something is wrong in my trampoline

Well I get gpf after setting gs base

I need better logging for this gpf handler

I have yet to implement a stack trace

[bold grove]

@radiant grove

[radiant grove]

THIS IS REAL

A MOMENT IN HISTORY

[radiant grove]

also it mightve been 3 hours and not days

[radiant grove]

operating system

[azure rapids]

gpfs are cancer and whoever decied "yeah let's just shove 20 classes of exception in 1" should suffer

accessing a non cannon address is not a "protection fault"

[radiant grove]

if an error reason has "general" in it you need to reconsider

[azure rapids]

not even the error code is fucking helpful

only for segment based gpfs

if the error code is 0 you cannot figure out why without decoding the instruction that faulted

which is stupid

like for page faults you can figure out what it tried to access and how and where

with gpfs you get "here fuck you figure it out"

[radiant grove]

page faults arent even fatal

you just map the friggin page

[azure rapids]

exactly

gpfs fatal aren't in ring 3

and in ring 0 it's just fuck you

good luck

might as well panic because what else can you do

[radiant grove]

cpus like powerpc also have them im pretty sure theyre the only "real" exception they have

[violet anchor]

recover?

[azure rapids]

from a gpf???

how

1. you don't know way

[violet anchor]

they're per ap

[azure rapids]

in ring3 it's like oh it's prob a bad insturction

[radiant grove]

restart cpu duh

[azure rapids]

ahhhhh

yeah

[violet anchor]

you can reinit the ap

[azure rapids]

sure

[radiant grove]

[azure rapids]

or you can fix the code

🤔

[violet anchor]

fix it? that's crazy talk

[radiant grove]

GPF handler routine:

• report error
• display funny error message
• ask for press enter
• if enter pressed, download windows 11 home
• install it
• patch out all bypasses for microsoft account

[azure rapids]

😭

[violet anchor]

tbh I rarely see gpf in my os

it generates a whole different class of ring 0 handleable catchable errors

because interpreter

[bold grove]

I ended up fixing the issue

I was jumping to lalaland in my _start routine

[azure rapids]

oof

yeah that will do it

[bold grove]

Same

This is the first time I’ve gotten one actually

[gray cairn]

why the exception so simple

[ivory blade]

[ LOG ] you died

[violet anchor]

https://tenor.com/view/you-died-gif-9059314985743771972

[paper cloak]

There's like 3 different cases

[azure rapids]

that's 3 too many

[crimson plover]

well thats not true

32 causes

actually

at least according to intel

[azure rapids]

aren't most of these pmode only

but yeah still

[crimson plover]

we are in the thread of a pmode kernel

so idk kinda figured thats whats being discussed

[azure rapids]

oh right

[paper cloak]

most of those you wont actually encounter

in a long mode kernel

[azure rapids]

but floppa is pmode only

lmode doesn't deserve such greatness

[crimson plover]

lol

[bold grove]

lmao based

floppa is based for only touchng pmode

this post was made by the pmode gang

[bold grove]

man thank god for limine... at least my next kernel wont need a whole ass trampoline

making ap startup without limine is so involved

[bold grove]

I need me one of these 😣

[eager badge]

i'm tired enough that my brain can't digest that

[bold grove]

thats why you have the converter to digest the milk for you

[eager badge]

oh to it's milk to hdmi? that could be, um, something...

lolol

[radiant grove]

VGA-to-carrying handle adapter

screws on connectors are powerful

[bold grove]

long ahh function

[eager badge]

that doesn't look too bad. the length is broken up by all the little code blocks

[radiant grove]

does this mean

i just downloaded the entirety of nineteen eighty four you cant stop me

[bold grove]

I’m gonna use macros to make this cleaner

Because it’s pretty clunky

Pagemap copying is always a trip

Oh also guys guess what

I’m working on a 64 bit kernel behind the scenes

[bold grove]

Based

Complicated ahh routine

[radiant grove]

i need to grab a perfectly functioning slab of code and make that into a message bubble

antimeme

[bold grove]

Dw my copy pagemap is tested

Also my nuke pagemap

Oh also @radiant grove I fixed my mmio

[bold grove]

Amazing book btw

One of the best books ever written

Along with Lolita and Moby Dick

And crime and punishment

And “how the steel was forged”

So good

And “beyond good and evil” by Friedrich Neitzsche

There’s some good Bosnian books too

[paper cloak]

You should CoW

[bold grove]

Too complicated for my dumbass

[paper cloak]

its actually simpler

[bold grove]

Yeah but then I have to make my page fault handler deal with it and I’m just not tryna do that rn

I’ve got other priorities

But at some point I’ll impl CoW

I had an old vmm rendition with CoW

[bold grove]

I need to make my logging thread safe

I might be getting a new car here soon

[bold grove]

well fuck

[bold grove]

well
my cpu fails to go idle now
i made a mini aml parser
and now everythnig is fucked up

and now my allocator isnt working

but im sure thats because none of my ap's even started

[radiant grove]

floppa os ACPI incident

[bold grove]

7 million dead

[gray cairn]

relatable when i do:

#define LOG<insert_filename>C_PError

[static tartan]

now we do nothing

[bold grove]

I need to change the font tonight

I’m getting sick of this one

[bold grove]

I’m gonna do something more retro

Fits the vibe of the os

[radiant grove]

powerpc

mips

oh wait

the font

i want to change my font too

i should do something similar to the mac monaco font

[bold grove]

@rigid root i actually made a decent aml parser

not the memcmp bullshit

[rigid root]

damn

can u show it

[bold grove]

yes holup

[bold grove]

https://paste.ofcode.org/333ABTMKd47aZKUptkkkY34

[rigid root]

yeah i guess it is a "parser"

but its still as fragile as the s5 memcmp method

simply because you're parsing executable code

while also ignoring _PTS etc

[bold grove]

Ok thank u for the feedback

Any tips as to make it safer

[rigid root]

well u cant without actually you know, doing the full thing

like execute the code, build a namespace, initialize it, then evaluate _S5, then evaluate _SST and _PTS, then write the registers with the _S5 values

[bold grove]

okay thank u

will work on it

[rigid root]

yeah sure

feel free to ask questions

[bold grove]

:) thank you

[rigid root]

notice how i said evaluate here, that means all of those can be either a plain object, or a method that u execute and grab the return value of

and aml is designed around that assumption

because there's not a MethodInvokeOp

Theres just named references and u decide whether to execute or just grab the raw value

[bold grove]

ok

imma make a namespace tree

[rigid root]

yeah u can just use linked lists with 3 pointers

parent, peer, child

[bold grove]

yeah like this?

typedef struct acpi_ns_node {
    uint32_t name;
    uint8_t* aml_start;
    uint32_t aml_len;
    struct acpi_ns_node* parent;
    struct acpi_ns_node* children;
    struct acpi_ns_node* next;
} acpi_ns_node_t;

[rigid root]

almost

typedef struct acpi_method {
    uint8_t* aml_start;
    uint32_t aml_len;
    uint8_t sync_level;
    bool should_lock;
};

typedef struct acpi_object {
    union {
        struct acpi_int int;
        struct acpi_method method;
        struct acpi_buffer string, buffer;
        // a whole bunch of other stuff
    };

    acpi_object_type type;
};

typedef struct acpi_ns_node {
    uint32_t name;
    struct acpi_object* obj;
    struct acpi_ns_node* parent;
    struct acpi_ns_node* children;
    struct acpi_ns_node* next;
} acpi_ns_node_t;

[bold grove]

ok for sure

[bold grove]

ok so smp fucked up everything

so im getting rid of it

[bold grove]

I have so many bugs with smp im just not willing to work out

[bold grove]

Like my stupid page frame allocation doesn’t work for some fuckass reason

My merge() method just nukes everything

[bold grove]

Anyways

I’ve created the name space tree

I’m not parsing executable code anymore

[bold grove]

shit man

i kinda recieved some devastating news so

i might not work on the os today

someone i used to be very close with passed away

[bold grove]

i completely forgor about this comment 💀

[bold grove]

I placed a random void shitfuck() in my repo @radiant grove

Anyone who finds it gets a cookie

When I push to main today

[radiant grove]

k

make it integral for system operation

[bold grove]

Everything works again

[bold grove]

Bro I just tried to smoke a black and mild

Like those cheap cigars from the gas station

I genuinely almost threw up

https://tenor.com/view/shannon-sharpe-black-mild-turn-gif-3099690656329693077

[radiant grove]

lol dont smoke

[bold grove]

No I love lung cancer

[bold grove]

first person to find this wins a cookie

[ivory blade]

is it this repo? https://github.com/amar454/The-Flopperating-System

[ivory blade]

not in repo btw

i searched for 9 hrs

[torpid viper]

it's not in repo

look at commit

9 days ago

he didn't push

[bold grove]

Not yet

[bold grove]

I’m getting eaten alive by my math homework help me @high hawk 😭😭

Linear algebra is hard as fuck bro

I don’t want the answer but I’m just dying

Let $$A \in \mathbb{R}^{n \times n}$$ be a real matrix such that:
1. $$A^3 = A$$
2. $$A \neq 0$$ and $$A \neq I$$
3. $$A$$ is not assumed to be symmetric or diagonalizable

⸻

(a)
Prove that every eigenvalue $$\lambda$$ of $$A$$ satisfies
$$
\lambda \in {-1, 0, 1}
$$

⸻

(b)
Show that
$$
\mathbb{R}^n = \ker(A) \oplus \ker(A - I) \oplus \ker(A + I)
$$
if and only if $$A$$ is diagonalizable.

⸻

(c)
Assume that $$A$$ is diagonalizable. Prove that there exist projection matrices
$$
P_0,; P_1,; P_{-1}
$$
such that
$$
A = P_1 - P_{-1}
$$
with
$$
P_0 + P_1 + P_{-1} = I
$$
and
$$
P_i P_j = 0 \quad \text{for } i \neq j
$$

⸻

(d)
Suppose instead that $$A$$ is not diagonalizable. Prove that at least one Jordan block corresponding to eigenvalue $$-1$$, $$0$$, or $$1$$ has size greater than $$1$$, and explain which eigenvalues can have defective blocks and why.

⸻

(e) (Bonus)
Classify all real matrices $$A$$ satisfying
$$
A^3 = A
$$
up to similarity.

[radiant grove]

what

math is scary

uhhh x=2(0.8)^y

[high hawk]

I mean, it might help to look up the classification of finite-dimensional matrices up to similarity.
Namely characteristic vs minimal polynomial (see Carley-Hanilton theorem), generalized eigenvectors, algebraic vs geometric multiplicity, Jordan normal form, etc ...

[bold grove]

Thank u

[bold grove]

Kinda been taking a break

[blissful grove]

understandable man - hope to see you back at it soon.

[bold grove]

so i was convinced my whole repo was fucked

the clangd lsp was broken

thankfully zed has a button to restart the lsp

and now everything works

im adding allocation classes to my vmm

i added the classes

[bold grove]

Yeah I’ve been at a bit of a standstill progress wise

[bold grove]

okay ive fixed lots of issues

things seem to be better

i was having issues creating init process thread

figured out why

i was calling my early allocator for some fuckass reason

and after init_stage_early() it gets destroyed

keyboard works!!!

[bold grove]

dude

i just found such a nice font

[radiant grove]

literally vga

[bold grove]

It’s not but similar

[bold grove]

My virtual memory subsystem is extremely fast I just tested it

[bold grove]

my early allocator is borked

might just remove it

because i use regular kmalloc for my acpi

[bold grove]

i added configs for the init

[warm pasture]

crazy

[warm pasture]

why's that a problem tho 🤔

[warm pasture]

I have 3 stages for some reason
well for no reason really
my init code is the most fucked up crap I've ever written ✨

[radiant grove]

RIP

[warm pasture]

if it works it works
I wanna know why's having the general purpose allocator serve acpi considered bad
if i understood what the floppa boss said correctly

[bold grove]

It’s not “bad” it’s just I’d rather do my acpi init in INIT_STAGE_EARLY

But now I have to do it during INIT_STAGE_MIDDLE

Typically acpi init is done earlier

[paper cloak]

How did you test it

[bold grove]

Just mapping and unmapping pages in rapid succession

I can map the whole address space in under 50ms

[paper cloak]

You can't claim something is fast unless you compare it

[bold grove]

Facts you right

Imma try to test bentobox i686 to compare because it’s the same arch

@foggy cedar

Maybe xv6 too

[foggy cedar]

i686 bentobox is kinda crap lol, that was my first ever paging code that I wrote but you should be fine as long as you don't run userspace apps

[bold grove]

Testing bentobox against mine, mine is about 1.7x faster

That’s just because I optimized the fuck out my vmm

[foggy cedar]

ah cool

[bold grove]

adding some more syscalls

[bold grove]

Added sys_waitpid and sys_getdent

[bold grove]

im working on some other stuff now

[bold grove]

Idk what else to add

I could try smp again

[ivory blade]

maybe add an userspace with apps and usermode

[bold grove]

I should do that

[ivory blade]

yeah because you maxed out your kernel you can port anything now lmao

[bold grove]

You right 😭😭

[bold grove]

I made a raycaster

[simple vault]

niceee

[radiant grove]

hes stealing the secret formula

[paper cloak]

Do you do fisheye correction

[bold grove]

No

[bold grove]

so ive added a pager

and pager requests and stuff

and also linux vmm_area

[bold grove]

What the fuck

Why did you show me this monstrosity

[rigid root]

Isn't Dharma the company from lost

[bold grove]

I think it’s some Hindu expression

[bold grove]

Flopperating system progress is kinda slow

I’ve kinda been demotivated

There’s just some issues within my kernel im not in the mood to fix

Primarily with thread creation

[bold grove]

I’m working on the kernel nowwww

Sorry I’ve been a lazy bastard

Lots of school

[gray cairn]

relatable man

[bold grove]

Yeah the more I try to work on this kernel the more I realize I’ve basically maxed it out

The only feature it lacks is smp

[paper cloak]

insane take

[bold grove]

Maxed it out in terms of my goals

Wait

I have an idea

Hardware abstraction layer

Support multiple arches

Holy shit boys

Time to lock in

[gray cairn]

https://tenor.com/view/locked-in-monkey-monkey-meme-monkey-locked-in-monkey-face-gif-940796321824170934

[warm pasture]

riscv floppa chat is this real

[foggy cedar]

I rewrote my kernel for that

[bold grove]

I decided to try smp again first

[bold grove]

Got ap startup working

Now time to see how my kernel crumbles with concurrency

So far

Paging works

Everything else idk yet

Gotta do some more testing

[bold grove]

Update: virtual memory is working

I basically lock around vmm pagers

Instead of locking within my mapping/unmapping routines

Which makes things faster I think

Maybe

[bold grove]

HI GUYS

SORRY THERE HAS BEEN NO PROGRESS

ive been working on smp

i figured out a big issue

i made my ap_startup_done an atomic integer

so now it actually works

so my ap startup is working

[azure rapids]

oof

[bold grove]

yeah

[azure rapids]

32 bit moment

[bold grove]

yes

we love ia32

[azure rapids]

ia64 amd64 is better

[bold grove]

wait if u dont mind me asking what is the difference between my code and amd64 code for ap startup

i know that my trampoline code will be diff since i dpont have to enter long mode

[azure rapids]

well nothing

the tamp obv

[bold grove]

but i think this would work for amd64

[azure rapids]

other then the 32 bit cast

they prob should be uintptr casts

[bold grove]

yeah true

[azure rapids]

oh also bsp ids might not be u8's for x2apic

[bold grove]

oh ok i see

[bold grove]

i swtiched to those

im thinkking about making my entire mem subsystem into one mm_ namespace

and having just one giant mm.c

thats how actual kernels do it

@azure rapids what do u think

[azure rapids]

uhhh

I kinda subnamespace it

like mm_phys_

[bold grove]

thats nice

[azure rapids]

then my vm shit is under the vm namespace

[bold grove]

i might do something similar

yeah i was thinking having an mm and a vm namespace

so my heap and phys can go in mm

then like

mapping routines and region creation can be in vm_

[azure rapids]

yeah

I put all my paging shit in vm_

then all of my virtual memory allocation under vmm_ (really should be vma_)

[bold grove]

yeah

my vmm is fucking massive

like

1.6k loc and im not even done

i have allocation classes and all of that jazz

pagers too

[paper cloak]

what

I didn't know actual kernels had like 30k lines of code in a single file

[bold grove]

most kernels ive seen dont have like pmm or vmm they kinda just have a big mm module that everything is under

like you wouldnt see a pmm.c or even a physical.c

[paper cloak]

yes you would

It's just not called physical.c but something like page.c

And the mm module == vmm

BSDs call it vm

[bold grove]

im assuming mm in that case means actually managing physical memory blocks and shit, not the virtualization

so like your heap, frame allocator

etc

[paper cloak]

No, mm = memory manager

And like 99% of memory management is virtual memory management

[simple vault]

true

[bold grove]

I’m running into some race conditions within my frame allocator

[simple vault]

damn you're still going

How has it been

[bold grove]

I mean good

I had to rewrite a lot of stuff

I’m kinda struggling with this dumb race

I get absolute garbage when I allocate anything after the first few pages and it always occurs on cpu2

(im only supporting 2 CPUs because thats what the pentium has)

[simple vault]

Ohh well no one liked race conditions.

None of them are so bad for me so I just ignore it.

If it ain't fatal idc

[bold grove]

Mine unfortunately is

[simple vault]

I do feel them though

[bold grove]

I think im having a breakthrough tho

I think it’s within my buddy_split()

[simple vault]

Sometimes cpu-id returns null.

Once

Or 20 in a row

[bold grove]

That’s cursed

[simple vault]

Leading to a PF

:D

Just rerun it enough times and it works though.

[simple vault]

It is.

[bold grove]

Omg I figured out the race

Fuck yeah

[simple vault]

What was it

[bold grove]

Forgetting to lock before changing global state of allocator in buddy_split()

[azure rapids]

:P

yeah that would do it

[gray cairn]

AxeialOS doeses that

Most kernels I've seen has that tbh

Auroraos has pmm.c

[torpid viper]

well in most OSes i see a pmm.c

[gray cairn]

Even Modularus'es Distro (LiquidOS/Liqix) would also separate them

[paper cloak]

Most hobby OSes != Most "real" OSes

[bold grove]

Hobby os’s usually have a pmm.c

Real kernels don’t

Like bsd

[simple vault]

what do they use?

[bold grove]

They either have an mm module or vm module (that’s what the bsd’s do)

Abstracting virtual memory and physical memory as two different things seems trivial to me because 99% of memory management is virtual memory management, like rustc said

I think im gonna do it like this

Page allocation will go within page.c , then everything else will be in mm.c

[paper cloak]

Idk why you would put it all in a single file

[thorn dust]

yeah that's too large

[paper cloak]

It's gonna be like 3k lines at least

[bold grove]

[torpid viper]

oh right

[bold grove]

I’m studying at school rn and there’s this bitch playing country music through her headphones and I can hear it

It’s so cancer

Respectfully if you listen to country get out

looking through linux source code is so tiring

so many macros and just

weird naming schemes

______fart_shit_

average function name

like wtf is this static noinline void __ref __noreturn rest_init(void)

bruh

[bold grove]

@paper cloak how do you do arch abstraction for paging

Do I just create a common page flag bitfield and convert it into the proper bits for each arch

So like a PAGE_WRITABLE_GENERIC

Maybe can you help me with this too @torpid viper

[torpid viper]

that what i do

this work very well if some arch represent flags very differently

for exemple if a arch (like x86) has a flag NO_EXEC but another could have a flag EXEC

[paper cloak]

I do the pmap-like thing

instead of the pte thing

[radiant grove]

i remembered fartalloc

[bold grove]

Ah ok

Yeah Gaia has good arch abstraction

[paper cloak]

bro is reading my shitty code 😭

mhm well reading through the code its not that bad

could be improved

[bold grove]

Haha it’s not so bad

I went and fixed a lot of my shitty code recently

[gray cairn]

Too MUCH Blue

[radiant grove]

#define macro1 macro; 
#define macro2 macro1; 
#define macro3 macro2;

[static tartan]

why

[bold grove]

Bump

I’ll lock in today

[bold grove]

Off topic but

I took a lot of political tests today

And found out im basically a communist

[high hawk]

I got the same result for 8values

and I'm definitely not a communist

[bold grove]

Yeah I think “communist” to them means “a moral human”

[bold grove]

I just seem to be a bit more extreme than you haha

[azure rapids]

libertarian socialism on this test is just "government shouldn't control our whole life and the government should provide good social programs"

I feel that's a very common take

[crimson plover]

xd

tbh I would normally answer more extreme but some of the questions were kind of dumb imo

[azure rapids]

"Quality education is a right of all people."

[crimson plover]

like one was something along the lines of "progress should be strived for at all costs" or something

[azure rapids]

who the fuck is disagreeing with that???

[crimson plover]

like I cant agree with "at all costs" for literally anything

[crimson plover]

you'd be surprised

[azure rapids]

"It is very important to maintain law and order."

:P

[crimson plover]

lots of people used to and many still think women should not be educated at all...

[crimson plover]

yeah like why is that question phrased like that, but the other one is "at all costs"

I would agree that progress is very important too

¯_(ツ)_/¯

[paper cloak]

I have literally the same results

[azure rapids]

"All people - regardless of factors like culture or sexuality - should be treated equally."

duh

[paper cloak]

Right-wingers when people have rights and are happy: 😡

[crimson plover]

lmao

[paper cloak]

I get being right wing economically

fine, you're selfish

But being right wing socially is being an idiot

[crimson plover]

even if you have no empathy it still doesnt make sense economically

you have to be selfish and dumb

[paper cloak]

Things like "I made that money I should keep all of it"

I can see where they're coming from

[crimson plover]

yes but if you cant see a functioning society is a plus for yourself too

you are dumb

[paper cloak]

yeah

[crimson plover]

like rich people will go "so many homeless people eww filth garbage get them out", and then proceed to use tax loopholes to avoid paying taxes

the irony

[paper cloak]

I think they're aware, they just don't give a shit

same thing for their environmental impact

[crimson plover]

I think a lot of them genuinely also believe in the "pull yourself up by your bootstraps" bullshit

fail to see that just because the system happened to work for them it works against others

[paper cloak]

there was a guy in school the other day that literally said "if poor people are not rich it's because they didn't work hard enough"

[crimson plover]

[paper cloak]

mf do you think Elon Musk works more than the single mother with three jobs

[crimson plover]

the sad thing is they do

they believe meritocracy is real AND that it is good

[paper cloak]

You basically have to be extremely lucky and/or depend on social safety nets to be able to be born poor and become rich

[warm pasture]

I knew someone who said exactly the same thing

[gray cairn]

In a nutshell, the world is unfair

[radiant grove]

the "physician assisted suicide" one is utter vile insanity

who would even WANT to do that you have to have NO empathy for anyone

[azure rapids]

yeah bro it should be legal for someone to go to the doctors and say "I don't wanna live anymore" and just get killed

100%

I see 0 problems with that at all

[radiant grove]

worrying thing is that canada actually did it

[azure rapids]

aside from all of the problems

[azure rapids]

yeah :(

[radiant grove]

the "churches should be taxed like everyone else" is quite reasonable

id say agree as long as every other non church religious temple is also taxed

mosques, synagogues, etc

also ima post my results for some reason

actually crap i forgot there was a better image

removed the othero ne

my thoughts of "im on the center if politics was a spectrum" are probably confirmed

[crimson plover]

its very humane

[azure rapids]

I feel like if you just answer "I don't want poor people to starve" and "I don't want the government to control every aspect of my life" you get social liberalism

[crimson plover]

like 90 year olds who are suffering in bed cant move should be able to choose to end their life

we recognize this for fucking dogs but when its humans we make them suffer

do not understand why people think its ok

[radiant grove]

i guess but like idk i still disagree

its just like

utterly questionable

idk its just that theres something horribly offputting about that that i cant just put up with it

[crimson plover]

naturally death is offputting

[static tartan]

they cant???

[crimson plover]

assisted suicide is illegal in many places

[static tartan]

but also

[torpid viper]

well if you have an non curable and extremly painful disease ?

[crimson plover]

the awesome thing is no the fuck they didnt

obviously anyone cannot just go to a doctor and tell them to kill them and they will do it

you must meet strict criteria, etc, etc, there is a process

[crimson plover]

the point is to provide legal cover for what is 99.99% of time this exact situation

[radiant grove]

oh

misinformation on the internet

ok so yeah you have to have a mental condition or something

it still sucks bad either way, its as off putting as murder of 90 year olds

[crimson plover]

this really isnt the hill I care to die on but I will say I dont understand how taking someones life against their will is the same thing as not forcing someone to live a life of suffering and pain they do not want to live

[warm pasture]

agree

[warm pasture]

also its already legal in so many places to issue a DNR which is practically the same

[radiant grove]

dont want to die on this hill either, but i still dont know

cant agree nor disagree

[paper cloak]

For a DNR you have to die first

[warm pasture]

yes but some ppl dont really think this is actually what dying is

and in principle its not that much different
both cases u are just saying "bros I give up 🙏"

[paper cloak]

Yea it is

With medically assisted suicide you die at a known date

The other one you don't know

[warm pasture]

mm fair

[thorn dust]

it's not, there is no active and deliberate hastening of death in that case

there is a subtlety to this though that obviously the relief of pain etc in someone who is dying usually involves drugs that may well hasten death. this is not euthanasia so it's legal here and probably in most countries too

if you are familiar with aquinas' doctrine of double effect it's a bit like that

(by the same token it should follow that if a pregnant woman has some illness and the treatment would have the effect of terminating her pregnancy, that is permitted by catholics because the goal is treating her illness not an abortion, even if it does cause abortion in the process. but judging by what you hear about america nowadays they probably don't have that allowance there)

[warm helm]

We’re back!!!!

I missed working on this

[hexed notch]

heeey, you're not amarat, you're his evil brother! What'd you do with amarat?!

[warm helm]

He’s long gone

[hexed notch]

[warm helm]

It is me tho 🙂

[hexed notch]

what happened with your other acc?

[warm helm]

Can’t get into it

Due to age verification

[hexed notch]

dang 🙁

[warm helm]

I sent a ticket to discord with my ID but they never let me log in again

[hexed notch]

good to see ya back!

[warm helm]

Thank you

I missed this place

[warm helm]

What’s up yall

Rn I’m working on page swapping

[hexed notch]

coolio

I've been trying to implment vmem recently

[crimson plover]

yo

[warm helm]

Don’t look at my vmm pls

[simple vault]

🙏

[warm pasture]

bro u suddenly vanished i lowk got worried about u 💀

😭

dang
really glad u r back
welcome back boss

[warm helm]

Thanks bro

[warm helm]

We back better than ever 😈🙏

[warm pasture]

all hail floppa the flopperator

[simple vault]

ohh when is age verification coming out

and when is corporate version for 300$ coming out

i was really praying for it

[warm helm]

I’m actually genuinely thinking of making a network stack so I can make floppa os a server os

Or at least have a server edition

[simple vault]

might need to upgrade to 64 bit then

[warm helm]

Oh definitely

I’m working on abstracting my vmm

So the switch will be easier

[simple vault]

sounds good

[warm helm]

Getting some more progress

Debugging some syscalls

[warm pasture]

is this the original floppa os or did u do a rewrite
cuz I remember u once talked about that o_O

[warm helm]

Original

[violet anchor]

there can be only one floppa

[warm helm]

I’m kinda stuck lmao

I’m getting fucked by this vfs bug

Whenever I mount I create some bullshit extra descriptor that fucks with everything

So when I create a mount point descriptor I somehow create 2

And one of them has garbage data

And the id of the intended descriptor is in the garbage descriptor

I have no clue how this garbage descriptor is getting created

But it happens every time

[warm helm]

So I’ve been experiencing extreme tiredness and and fainting and I just got diagnosed with diabetes 😭😭😭

[hexed notch]

dang

my brother has type 1 diabetes

[warm helm]

Type 2 but yeah

They said it’s because of my horrible diet lmao

I have an addiction to fast food and soft drinks

I drink like 4 large cokes a day

[warm helm]

My health has been better

Working on stuff rn

[crimson plover]

[warm helm]

@hexed notch why do u like c++ so much

I see no positives of it compared to a language like rust

[hexed notch]

Uhm, well I am slightly biased since it's pretty much the sole language I use but idk, I just kind of like it templates are cool, operator overloading is cool, having namespaces is nice, I like the syntax, I also think the tooling is pretty nice, rust kind of seems like a pain tooling wise

[crimson plover]

I hate the syntax

the other points are valid

but rust does all of them better imo

traits are fucking amazing

[hexed notch]

I have been meaning to learn rust at some point, but I figured I should get competent at C++ first

[crimson plover]

imo a much better paradigm than templates

[crimson plover]

probably fine

I do recommend rust

its not the only language I like

I just happen to hate C++

[hexed notch]

Well I'll use C++ til the end of time, someone has to give it some love :3

[crimson plover]

xD

[warm helm]

I’m having some issues with page swapping

I think I’m gonna abandon it for now

[crimson plover]

zamn

[west scarab]

Rust gets in your way too much sometimes

[crimson plover]

idk I kinda disagree

I agree it certainly make things more difficult at times

but I have yet to run into a scenario where it makes things more difficult for no good reason

[warm helm]

Just to be clear

None of my OS is vibe coded

I had a vibe coded printf for a while but I removed it

🙂

Just felt the need to say that bc now there’s “vibe coded” and “no ai” threads

I haven’t committed to the os in a while

I really need to here soon

[rigid root]

yes!

we're waiting for a kde port

[violet anchor]

if you reviewed it, it isnt vibe coded

[warm helm]

Trve…

[timber terrace]

this reminds me of face raiders on the 3ds

[warm helm]

I miss that shit

When they would like taunt you and stuff

[hexed notch]

OH YEAH! I remember that game!

[timber terrace]

so do I 💔

[warm helm]

I think a kernel rewrite is due

[crimson plover]

YIPPIEE

[warm helm]

I think imma use a simple free list for the pmm

But I’m gonna not abstract it with the pmm namespace

I’m just gonna make my page allocator page.c

And the virtual stuff under vm_

[warm helm]

Bro today is the 3 year anniversary of when I got malaria

That shit was fucking ASS

literally the worst days of my life

It was when I was in Nigeria

For a humanitarian trip

It ruined the whole trip

[warm helm]

Hey guys

Sorry I’ve been in and out of mental hospital

Bipolar is a helluva illness

But there is hope

I’m gonna start working on this again

[humble hearth]

take care fam

[warm helm]

Thank u bro u too

[humble hearth]

looking forward to follow this thread again, keep it up!

[warm helm]

Thanks bro. I have some cool ideas

I need to get past my curse which is smp

I can never get it quite right

[humble hearth]

one day it'll be just right

[crimson plover]

Yes always!

[warm helm]

There is progress being made on this I promise

My last commit was in February

I need to lock in yall

[warm helm]

Rn im working on switching back to text mode

[violet anchor]

why text mode?

[humble hearth]

VGA mode 13h ftw

[warm helm]

Bc I like the aesthetic

[violet anchor]

go for it

can't you just request the bootloader give you that mode?

only thing is that isn't portable is it

[humble hearth]

GRUB gives you text mode by default ig

[warm helm]

It does yes

[warm helm]

Nah it’s by default
