Errnos are freestanding

[dull grotto]

Anyone using PascalCase needs to be studied

[gusty kestrel]

yay 1001st message here

[gusty kestrel]

guys did some changes into main, took some code edited into the main branch from the @dull grotto merge to scratch branch

https://github.com/VOXIDEVOSTRO/Modularus

i going to sleep

good nightly builds

[covert heath]

[halcyon silo]

so this is the software equivalent of what Framework laps do

[gusty kestrel]

i've been procrastinating alot, i must make the default or inbuilt modules

[gusty kestrel]

well finally made a per module error context

which holds traceback key(for the registered module) and a mapper operation

[covert heath]

very cool

also have some good news

just traded my ram for a fully custom keyboard

veri neat

[covert heath]

will the builtin one better than others' impl?

[gusty kestrel]

no, they will be temporary, soon depending on the module it would be replaced by a better one

that's only to allocate memory for loading and linking the modules

[covert heath]

so this project is very open to the community?

[gusty kestrel]

indeed, everyone can make thier modules and plug it in

[covert heath]

so basically LFS but with kernel level

[gusty kestrel]

yup

[gusty kestrel]

for that we need a insanely stable API

[covert heath]

i hope modularus supports legacy bios?

[gusty kestrel]

it should ig, doesn't limine support bios?

well we could have grub too honestly

our compile time preboot options exist...

[covert heath]

it sure does, its just the fact that you didnt add explicit support for bios with AxeialOS

[covert heath]

i think it is possible to use both protocol

within an image

[gusty kestrel]

well i didn't have a preboot in mind for the AxeialOS ofc

[covert heath]

all you gotta do is handle mb2 in legacy mode, and switch to 64 bit

[gusty kestrel]

should be simple enough, maybe a compile time option

[covert heath]

with UEFI mb2 and bios/uefi limine, you can just detect the bootloader then init correspondingly

[covert heath]

what about dynamically?

[gusty kestrel]

also i have some problems related to the API standardization and API itself for modularus

[gusty kestrel]

ISO Hybrid?

[covert heath]

no the kernel itself

not the iso

this is just a kernel isnt it?

[gusty kestrel]

for a dynamic preboot?

[covert heath]

yeah?

[gusty kestrel]

that would need a way to abstract all protocols

tho i still do it partially in modularus

i.e BOOT_REQUEST

[gusty kestrel]

also ithink currently our API is too rigid

because of the static ops

it "assumes" a module of the certain type its gonna serve must have

any ideas how can we make it flexible? @covert heath

personally i think our API at current is too rigid and static

do you think that too?

[covert heath]

havent read the code too much

but the question is

what made you think so?

[gusty kestrel]

the operations

we define a static ops table for each thing (every part of the kernel)

and wrap under a proper callable function middle layer

like i just think what a module of each type must have in common

[gusty kestrel]

well you can read the headers and tell

another crazy idea i had was going to an anology (EVERYTHING IS A FILE) to a whole new level

[covert heath]

yeah

it is, not too flexible

while it is large

[gusty kestrel]

and thought i should port and rework the VFS in AxeialOS and port to the modularus core and MAKE each kernel abstractions in a pseudo FS 😭

[covert heath]

expandability might become an issue

[gusty kestrel]

yeah because kernel defines everything, the one to use it and declare is the modules

[covert heath]

still validating my mm to bochs

[gusty kestrel]

crazy idea isn't it

[covert heath]

wait, each?

[gusty kestrel]

but yeah that would make it INSANELY MEGA COMPLICATED

[gusty kestrel]

i mean for each abstraction layer

[covert heath]

i dont think its INSANELY MEGA

its just sysfs++

[gusty kestrel]

well does that make it doable?

[covert heath]

like its just very very exposed

[gusty kestrel]

and actually fix the the API rigidness problem?

[gusty kestrel]

we can have tons of security over that

which would make it a unix-like VFS ++

so do you think this would solve the API rigidness problem?

[covert heath]

moving the abstraction into VFS pulls unwanted dependenciesd

not a bad idea though

but add overheads,

[gusty kestrel]

obviously that's memory

VFS needs a kernel heap

but abstraction is in the VFS

that's circular

[covert heath]

yeah...

[gusty kestrel]

unless we have a unreplacable memory manager

[covert heath]

that somewhat violates the philosophy if youre strict

[gusty kestrel]

which woulld just BREAK the modularus goal

[covert heath]

or we could cheat

[gusty kestrel]

yup, violates the philosophy of being 100% replacable

[covert heath]

making Modularus' foundation kit

which is the same as builtin

but not builtin

and it simply needs the kit to simply work

[gusty kestrel]

also i may have an idea around that circular problem

[covert heath]

what is it then

[gusty kestrel]

making a simple MEMORY manager ONLY FOR the VFS, but the main memory manager resides in VFS abstraction

[covert heath]

isnt that breaking the goal?

[gusty kestrel]

the catch is that memory manager IS ALSO replacable

so we would have TWO memory manager abstractions

[covert heath]

and to that module must be special

[gusty kestrel]

one with OPS

[covert heath]

since it cannot use the kernel VFS

which is another kernel module type to handle

[gusty kestrel]

and one with the VFS abstraction

[gusty kestrel]

they can be called defaults

they already have the name

so do you think this thing works?

[covert heath]

maybe

[gusty kestrel]

also on the plus side this would allow us to move the MODULE management system also to the VFS

so we can move 98% if the stuff to VFS (sysfs++)

the other 2% being the bootstraps defaults like the bootstrap temp MM and the bootstrap loaders and linkers which would also use the same temp bootstrap MM

wait we can also use COM

Component Object Model

[gusty kestrel]

So refactoring and completeing the VFS

and also stole the VFS from AxeialOS

its too reliable

and will completely complete it into a complete VFS

4000LoC VFS to a 8000LoC one

Also went to static inbuilt heap for the VFS ONLY, which is only 64MiB

which is way more then enough for my VFS to abstract every single module lmao

[covert heath]

jesus

[gusty kestrel]

https://tenor.com/view/krnl-roblox-exploit-exploit-robux-kernel-gif-19597348

[gusty kestrel]

literally me after clobbering RCK and R11 when doing sysret

[gusty kestrel]

also what about logging?

memory fd?

[gusty kestrel]

yeah, AxeialOS vfs wasn't complete, and was quite partial

like user, group, modes, flags and permission support were stubbed out

[gusty kestrel]

I have this idea

[gusty kestrel]

shitty logo from gimp

i'm trying it for the first time btw

😭

[gusty kestrel]

@wooden linden rate this shit

[wooden linden]

Ngl bad

NOT BAD

AUTO CORREXT

WHAT THE FUCK

[gusty kestrel]

lmfao

[wooden linden]

I’m so sorry

[gusty kestrel]

first try in GIMP

[wooden linden]

💀

[gusty kestrel]

because i'm on arch ofc

[wooden linden]

I wonder if a logo like this may go hard

https://en.wikipedia.org/wiki/Menger_sponge

[gusty kestrel]

teh reason the logo is file icon with blocks is because Modularus would use abstraction for modules as EVERYTHING IS A FILE

[wooden linden]

You could even render it inside modularus live on boot (inside userspace)

[wooden linden]

Maybe better for the bin bricks version / the distro

[gusty kestrel]

VFS is the backbone of this shi

also GIMP isn't that hard, i like it

i've seen videos

also followed no tutorial as its for NOOBS

[halcyon silo]

lie

[wooden linden]

Dawg 😭

[gusty kestrel]

what you'd expect from a trying GIMP for the first time 😭

[wooden linden]

• I’m on an iPhone and the autocorrect is known to be fucking dookie shit I hate it

[halcyon silo]

@gusty kestrel @gusty kestrel dont

DONT

USE FIGMA

FIGMA > GIMPY

GIMP looks like an airplane cockpit ngl

• ITS ONLINE + ITS FREE FOR THIS PURPOSE

attack on titanic

[wooden linden]

I could also design somthing in aseprite w/ pixel art or somthing

[halcyon silo]

use blockbench @gusty kestrel

[halcyon silo]

for smth like this

[pastel bronze]

its not free.

[halcyon silo]

it generates blocky 3d art, easily

[halcyon silo]

it is

only heavy stuff are paid

i myself did in figma

[wooden linden]

Or blender

[halcyon silo]

https://github.com/Z-Proj/ZenOS

[halcyon silo]

blender is too powered for what u need, only blocky stuff

[wooden linden]

I hate block bench because it’s good for Minecraft stuff but my friend constantly asks for help because thier flatpak image stinks and they don’t want to use the web version

[halcyon silo]

Modularus = Lego kernel

[wooden linden]

Blender is certainly not “too” powerful. It’s exactly what you want especially if you want to render it nicely

[halcyon silo]

i agree, but just to make a simple logo, u gotta learn a lot

i got as far as a fully detailed apples in a black bowl with knife

then quit

[wooden linden]

Blender is not that complicated. It’s a very good example of open source software done well

[halcyon silo]

thats a point i agree, but

yeah, the learning curve

depends on the person

[halcyon silo]

this could hv been done in ms-paint, the og one tbh

[wooden linden]

That’s with most 3d software to be honest. And for a cube you just need to use some array modifiers and Boolean modifies etc

And it will probably be faster to render due to using them

[halcyon silo]

procedural generation mods or smth, help too ig

[halcyon silo]

Eevee > Cycles

[wooden linden]

You don’t need to shit on the logo

It’s really not that bad

[halcyon silo]

ik but i dont think gimp was needed for that

[wooden linden]

Cycles is a very good renderer and it should be used. Eeevee can not reproduce all of the proper lighting effects

[wooden linden]

I think this is getting off topic anyways lmfao

[halcyon silo]

ye

[dull grotto]

Just write svg code smh

[dull grotto]

Or use Latex with random packages

[halcyon silo]

then ig u can use this as inspiration

how do i clear my recent reactions, theyre shit

[dull grotto]

Try using reactions that aren't shit

Take a look at my Logo

(I'm bad at drawing or designing stuff)

[halcyon silo]

"Tobacco leads to cancer, heart attacks, lung disorders, and other deadly diseases"

"Mutual funds is subject to market risk. Read all terms and conditions carefully before investing"

This is what lowkey hits me when im high in ADHD

[halcyon silo]

damn this needs rating 8/10

modular and simplicity

[dull grotto]

Ikr?

[halcyon silo]

the choice of material art and a perfect color palette is astonishing

the simple and creatively constructed text glyphs say it all

[gusty kestrel]

GIMP is nice, blender is too much for my potato HP book to handle

[covert heath]

dayum

[gusty kestrel]

what about my logo?

[covert heath]

which one?

i saw a few designs

[gusty kestrel]

This

[covert heath]

that is quite similar to my REGS_RETURN_VAL

[covert heath]

this for some reason reminds me of code blocks

[covert heath]

the font could be different

[gusty kestrel]

lol was reworking on the VFS

[gusty kestrel]

i thought so

[covert heath]

maybe i should make my own logo

[gusty kestrel]

AeroSync

[covert heath]

yeah

[gusty kestrel]

i see

[covert heath]

Linux is tux

[gusty kestrel]

Mascot?

[covert heath]

but BSD, UNIX, MACH, and XNU is itself a logo

[covert heath]

idk

deciding between a mascot and a logo

[gusty kestrel]

BSD has a demon

which is a Mascot

UNIX is a logo

[covert heath]

i think thats freebsd

[gusty kestrel]

yea

Logo is nicer

[covert heath]

it is

the current github page logo is its current logo

https://github.com/assembler-0/AeroSync

[gusty kestrel]

mascot is a way to create an identity of something with character, animal or fictional being

[gusty kestrel]

ngl thats not bad AT ALL

its clean

[covert heath]

definitely not taken from pinterest

[covert heath]

i think so

[gusty kestrel]

lmao

well still thinking about Modularus logo

[covert heath]

just change the font ig

[gusty kestrel]

also the next push will be a complete re write

to VFS

and removing the rigid abstraction headers

[covert heath]

i have no motivation to write aerosync rn

[gusty kestrel]

lol why?

[covert heath]

*not in a giving up way

[gusty kestrel]

stuck on something?

relatable feeling

[covert heath]

just that lunar new year is comming (just 1 more day of school)

and i simply dont want to do anything lmfao

and just eat, sleep, cycle

also waiting for my stuff to arrive

[covert heath]

kinda

[gusty kestrel]

after coming back home, directly i have last year of my school

[covert heath]

execve is not execve-ing

[gusty kestrel]

the ultimate final exams

[gusty kestrel]

same for AxeialOS

[covert heath]

after the holiday i have a 2nd mid-semester exam

[gusty kestrel]

all the best for that, well last year of school feels like i'm gonna escape this shit for once and for all

the school eats lot of my time in the day

barely can do something that i actually like

[covert heath]

so relatable here

[gusty kestrel]

i love to sit on my corner desk, make something out of scrap, do something new or most of the time code, read docs and other peoples code

[dull grotto]

Sounds like my college

I spend most of my time researching, and scrolling reddit

I should be studying for my mid-sem but I'm building my website instead 💀

[gusty kestrel]

same dude, i have my final semester of school and i'm reworking my VFS for Modularus

[covert heath]

here doing kernel work in the same situation

[gusty kestrel]

7 days ? 6 stars? noice

[gusty kestrel]

finally reworked the VFS

Pushed the changes! https://github.com/VOXIDEVOSTRO/Modularus

Also lets talk about abstraction

because here we are taking EVERYTHING IS A FILE to an extreme level

SO i have two abstraction strategy

one is having a single psuedo fs like sysfs but insane (sysfs++)

and is per part fs

like schdfs

threadfs

processfs

loaderfs

idtfs

gdtfs

etc etc

i think i should make a poll

[gusty kestrel]

@covert heath i'm going with the sysfs approach btw lmao

everything IS A FILE

Also pushed the code you can review

[covert heath]

how much

[gusty kestrel]

EVERYTHING

[covert heath]

even more than plan9? (plan9 is more everything is a file than unix)

[covert heath]

sure

[gusty kestrel]

yeah the entire kernel is just that like scheduler runs from file too

idt/gdt/tss/ist will be also set from files

system calls will also be set, registered and called from files

fucking everything from file

also we need a way for kernel logging

without AGAIN breaking modularity

and also one thing is i'm using a statically allocated HEAP

bump allocator

for VFS nodes and stuff

[covert heath]

jesus

[gusty kestrel]

64MB

nodes dont need alot of memory iirc

few bytes

[gusty kestrel]

first we need a sysfs layer as usual also i think it would be mounted as a "/"

because before a initramfs we need basic stuff

so sysfs would be the mount and the main disk filesystem root will be mounted elsewhere like /mnt/drive1

/mnt/drive2

etc

tho it would be still handled by the modules anyway

Back to VFS and making the core of the abstraction. now my question really is. FUCKING HOW

how can i know everything is working?

because i need the sysfs++ to be present first

but to log anything in the first place i need a bootstrap loader AND linker

[covert heath]

bro is using sysfs++

[gusty kestrel]

that's what i'm gonna name it

[covert heath]

the ++ is just there to denote my intentions about a more deeply integrated pseudo fs

[covert heath]

copyrighed

whatever though

[gusty kestrel]

its copyrighted?

[covert heath]

idk

but i think of the name first didnt i?

[gusty kestrel]

lemme check

no it isn't

duh

[covert heath]

10 minutes

[gusty kestrel]

source: ||trust me bro||

[covert heath]

no i mean not the copy right stuff

[gusty kestrel]

what

[covert heath]

just the name itself

[gusty kestrel]

almost 10 stars 🥹

lets surpass AxeialOS

with 8 stars lmao

[covert heath]

bruh

mine dont even get pass 5

so sad

@gusty kestrel how do you parse the dmline?

can i use yours? mine is unstable

[gusty kestrel]

what?

[gusty kestrel]

also sure if you are fine with porting mess

[covert heath]

cmdline*

[gusty kestrel]

oh i see, sure you can use from the AxeialOS kernel

[covert heath]

is it working?

plus

licensing

[gusty kestrel]

MIT

you are fine

[gusty kestrel]

yes it works

[covert heath]

k thx, will have a look

can it do key:vaule?

plus, where the hell is it?

[gusty kestrel]

for processes right? like /proc and stuff?

[covert heath]

no?

the cmdline parser?

[gusty kestrel]

i don't have a shell yet?

or a terminal in axeialOS

[covert heath]

COMMAND LINE

AT BOOT TIME

dude

not a shell

[gusty kestrel]

OH YOU MEAN CONSOLE

[covert heath]

??

no

[gusty kestrel]

Thats what my EarlyBootConsole is

[covert heath]

dude its this

[covert heath]

cmdline, NOT console

Linux cmdline

wait

aka boot args

[gusty kestrel]

BE MORE explicit on what you mean lmfao

[covert heath]

whar?

we all call it cmdline

the kernel cmdline

there is no 'shell' in linux

[gusty kestrel]

AxeialOS doesn't use a command line

[covert heath]

ITS NOT COMMAND LINE

its just cmdline

and that derives from Linux ()

or whatever UNIX

[gusty kestrel]

okay cmdline

[covert heath]

ok so where is it?

[gusty kestrel]

AxeialOS doen't use one

[covert heath]

☠️

how

so its compile time config only?_

[gusty kestrel]

whythe fuck do i need extra arg 😭

[gusty kestrel]

YEAH

AXEKCONF

for now AxeialOS uses Compile time options

[covert heath]

nokaslr initrd= nomigrations sysctl

bruh i literally just realized some of my pills for my cold needs to be taken 30 mins before meal

and i have taken it after meal since day one ☠️

[gusty kestrel]

bruh what

[covert heath]

i probably not gonna die any time soon tho

[gusty kestrel]

obviously

[covert heath]

goddamn it linux 275 loc cmdline parser is more functional than my 500 loc flopware

[gusty kestrel]

thinking about sysfs++

[gusty kestrel]

lmfao, should i use cmdline parser for Modularus too?

liek for debugging, tooling and etc

[covert heath]

its not should or shouldnt

its standard

[gusty kestrel]

would make it dynamic

[covert heath]

whar?

you mean seperated parser?

[gusty kestrel]

yea maybe

[covert heath]

i mean why not

with cmdline you c an do lots of thing

[gusty kestrel]

because any way loggers would be external modules or temporary builtins

[covert heath]

like configure the kernel OTF

on -the-fly

[gusty kestrel]

my Modularus is gonna be modular and dynamic SO i guess its worth it

well what about sysfs++

[covert heath]

its standard though

[covert heath]

ngl its just any other pseudofs

so its a rebranded of the same thing

unless you made it special

[gusty kestrel]

well it must have some extra stuff to handle all the dynamic and nested interfaces of the modules

like must be interactive

like devfs

you can write and read to it

to change states, configure, run, call and query

[gusty kestrel]

LESSSS GOO finally we surpassed AxeialOS

so gonna go and make the sysfs++

would the ops: read, write, open, close and ioctl be fine? for sysfs++?

i do think so, well its just like any other ordinary devfs but without block and char devices

Also wondering should sysfs++ be a seperate module?

external or builtin but disposable?

Tho we need a memory manager for the linker

well as external or builtin as usual

this is complicated

yea we should make builtins for memory manager, and linker ONLY, sysfs++ logic would be embeded as core

because sysfs++ would be mounted as "/"

as we wont have a early boot image (initrd) which also depends on the vendor who is gonna make the kernel distro

[gusty kestrel]

made a dirty heap static abstraction https://github.com/VOXIDEVOSTRO/Modularus

partially made the sysfs++ header

dirty heap is just basic temporary heap layer

and made the first builtin

which is just a statically alllocated 64MB pool with a bump allocator

GAWD, core is getting big asf really fast

PascalCase my beloved

[dull grotto]

Super cursed

[gusty kestrel]

lmfao

[high umbra]

might do this myself

[gusty kestrel]

Nice

[gusty kestrel]

dayum, registering the sysfs++ or mounting it causing a fault

but i dont have any IDT and GDT builtins

well why there would be builtins

we just triplefault as its cant be handled

[gusty kestrel]

less gooo 10 stars

[gusty kestrel]

but to make the gdt, idt and the linker i need sysfs++

also the fact i dont have any logging

the screen is just as blank as my Untitled1 file in vscode

i may have to manually troubleshoot by commenting stuff to know where exactly it faults

like the main creation? or the mounting or an entry creation

[covert heath]

tf

fr

[gusty kestrel]

have to manually troubleshoot

manual tracing

[covert heath]

bruh

[gusty kestrel]

kernel loggers would also be a seperate module 😭

what would you expect from this project

[covert heath]

yeah

fair point

[gusty kestrel]

also its insane that its SO possible

[covert heath]

i mean exokernel are a thing

[gusty kestrel]

Thats a different concept

[covert heath]

ik

[gusty kestrel]

it mean pushing everything to userspace

[covert heath]

but it shares the fact that the kernel is nothing

[covert heath]

so it doesnt need the compatibility to fit with users impl?

[gusty kestrel]

this kernel is dynamically monolithic sortof

[gusty kestrel]

yea maybe

[covert heath]

what even is that

[covert heath]

what?

[gusty kestrel]

not a real kernel architecture btw

simply:
Modularus is:
Monolithic: No
Microkernel: No
ExoKernel: No

it doesnt fit in any

[covert heath]

its a bit of everything

you got the lightness of exokernel, plugins of microkernel, and rigid of monolithic (supposedly)

[gusty kestrel]

speed of a monolithic

[covert heath]

*i mean modules

[covert heath]

depends

not sure with that much of abstraction

[gusty kestrel]

all modules would be "linked" to kernel dynamically

[covert heath]

thats what a module loader supposed to do

[gusty kestrel]

*Linker

also modularus is weird as i said

its a weird yet a possible idea

to implement and research

[covert heath]

again are you planing to do just a PoC or more than a PoC

[gusty kestrel]

more then a PoC ofc

its gonna be a complete kernel

kernel distro?

[covert heath]

idk

either a kernel or a full os

[gusty kestrel]

a full OS to ofc

[covert heath]

very nice

[gusty kestrel]

and both, complete kernel and in future a OS distro

[covert heath]

im actually already planning a distro

for AeroSync

for its 9th release

[gusty kestrel]

Same after it compeletes

[covert heath]

vastly depends on the dev

[gusty kestrel]

i have the sanity, time and energy to do that

probably...

[covert heath]

then its more likely

[gusty kestrel]

sysfs++ IS WORKING LESS GOO! fixed the fault

FIRST THINGS FIRST I'M GONNA MAKE another inbuilt and also loader BUT BEFORE THAT i would make a builtin FOR some basic printing FIRST

because GOD lack of logs are annoying

i will only do UART for now

pushed the sysfs++ changes! https://github.com/VOXIDEVOSTRO/Modularus

[gusty kestrel]

lets get to working

i must fix the sysfs++

cuz... it doesn't work? for some reason it is giving me ENOSYS

meaning no operations

in the VfsOpen

[covert heath]

whar?

ENOSYS is no impl ready

[gusty kestrel]

i have temporarily used it as no operation error

because i'm still considering to make my own set* of errnos

set*

[covert heath]

dued

that would absolutely be horrible

if one expect UNIX errno

[gusty kestrel]

really?, i did think of that

and thought of using a complete set of UNIX Errnos

[covert heath]

all you need is return codes

so copy userspace errno.h and defer the deadly errno local var

anyways, added clang CFI to my kernel

[gusty kestrel]

nice

[covert heath]

just another layer of reinforcement

[gusty kestrel]

Yea, also you have the complete set of UNIX errnos?

i can use

wait you PR has it

[covert heath]

yeah

not sure if its complete

i think linux version is in asm-generic

[gusty kestrel]

even linux ones would also be fine

[covert heath]

its this

https://github.com/torvalds/linux/blob/master/include/uapi/asm-generic/errno-base.h

the base

maybe this is https://github.com/torvalds/linux/blob/master/include/uapi/asm-generic/errno.h

btw just out of curiosity @gusty kestrel

can you test my kernel? (if you have time)

[gusty kestrel]

Absolutely

[gusty kestrel]

how can i run it?

[covert heath]

unpack and move?

to esp

or you can have the iso

[covert heath]

i prefer using this since its lighter

[gusty kestrel]

thanks for the iso

[covert heath]

and skips ISO hassle entirely

(for some reason, i have trust issues with isos)

you can choose the verbose or non verbose

[gusty kestrel]

NOICE it worked

[covert heath]

qemu?

[gusty kestrel]

yea

[covert heath]

ig thanks

[gusty kestrel]

its cool

[covert heath]

real hw would be better since i wouldnt want to waste your time'

btw bios from 2014

[gusty kestrel]

i dont have a flash drive or any external drive lying around to boot here

on my laptop

[covert heath]

i see

np

[gusty kestrel]

well its cool asf

[covert heath]

thanks

hows modularus then?

[gusty kestrel]

fixing the sysfs++ problems

[covert heath]

what problem?

[gusty kestrel]

because for some reason all vfs operation return no operations error even tho the sysfs++ is mounted and registered

without any errors

[covert heath]

lmao

[gusty kestrel]

VFS would only return such errors when the following filesystem doesn't have itself registered

also because i dont have any logging, thanks to errnos and can easily trace errors

[covert heath]

no logging and seeing errors conflicts

using a remote debugger?

[gusty kestrel]

no, adding conditionals during the sequence (if(Probe4Error(anything))) or != GeneralOK and making it intentionally cause an exception like if -ENOSYS do a ud2, if a EINVAL do a division fault, if a ENOMEM do a pagefault

[covert heath]

bruh

[gusty kestrel]

then i can check the qemu logs what exception caused it

[gusty kestrel]

lmfao, thats HOW OGs debug

[covert heath]

1990 ogs

[gusty kestrel]

indeed, tho its quite effective

[covert heath]

i think so

anyways, gonna push

[gusty kestrel]

and also way faster to do

imo

[gusty kestrel]

@covert heath FIRST MESSAGE FROM MODULARUS

[covert heath]

serial?

[gusty kestrel]

yes

[gusty kestrel]

Also fixed sysfs!

[covert heath]

cool

idk what to do now

[gusty kestrel]

I pushed: https://github.com/VOXIDEVOSTRO/Modularus

sysfs++ stuff

and finally the stuff

[covert heath]

cool

just doing mm stuff once agin

[gusty kestrel]

😭 why

[covert heath]

idk what to do

[gusty kestrel]

ig read modularus code as its interesting \j

[covert heath]

i was about to say PascalCase is-

[gusty kestrel]

did alot of stuff

[gusty kestrel]

I can't break that habit 😭

[pastel bronze]

incredibly readable, easy to understand and practical

[gusty kestrel]

Yes, ig for some people its an eyesore because they are used to seeing camelCase or snake_case

[covert heath]

in another world

[pastel bronze]

in another world your nick is Assembler

[covert heath]

+1 fell for ragebait

[gusty kestrel]

LMFAO

[covert heath]

anyways

[gusty kestrel]

well what should i do next?

make a builtin linker?

[pastel bronze]

make a fucking idt

[gusty kestrel]

that would be a external module

[pastel bronze]

oh wrong person

wait you dont have idt?

[gusty kestrel]

No?

[pastel bronze]

not wrong person then lmao

[gusty kestrel]

this kernel is only pure VFS and a pseudo fs mounted as ROOT

with few builtins

heap and a UART

Thats all it is 😭

[pastel bronze]

i give you my speedrunning osdev energy

[gusty kestrel]

Sure as I've been lacking a consistent focus, Its fragmented

[gusty kestrel]

imma make builtins for the linker and loader too

[covert heath]

yeah

[gusty kestrel]

loader would just use boot request

[covert heath]

moreover do you expect other to build modules for everything

or you will add a set of default modules?

[gusty kestrel]

Yes

[covert heath]

like the default kernel will come with

[gusty kestrel]

I may have simple modules atleast for testing

[covert heath]

nothing?

[gusty kestrel]

exactly

only few builtins

like which is the static pool, heap, loader and linker

thats basically it

[covert heath]

damn

[gusty kestrel]

then later on you can create externals for them and use them instead of the builtins

[gusty kestrel]

crazy project right?

[covert heath]

completely different from aerosync

[gusty kestrel]

obviously

[covert heath]

with aerosync im aiming full modularity for drivers

only

but not with the internals

[gusty kestrel]

Modularus aims FOR EVERYTHING

that's the goal, and i can see its working very well

modularity at its peak

[tired maple]

based

[gusty kestrel]

ig make builtins for loader and linker today???

[gusty kestrel]

@covert heath you think i should change modularus license? saw the conversation from #1471870285207568588

[covert heath]

what are you planning?

[covert heath]

current is MIT right?

[gusty kestrel]

Yes

[covert heath]

yeah, should change

for sth like this

[gusty kestrel]

added the loader btw

https://github.com/VOXIDEVOSTRO/Modularus

also star the repo dyum 🥀 , only 3 stars is broke asf

and a 10 star thread lmfao

[covert heath]

i have 5 ...

[gusty kestrel]

sad

what IDE do you use @covert heath ?

primarily?

[covert heath]

CLion

but prob gotta reinstall

[gusty kestrel]

Cool

[covert heath]

used it for like 3 months and its stack overflowing

[gusty kestrel]

VSCODE is unstable asf

[covert heath]

crashed 2 times

[gusty kestrel]

vscode crashes too

[covert heath]

i was scared about ram usage but not too bad-ish

thats also why i sold the ram

though the on-disk usage is insane

afaik

16G

*after you install alot of extension and doesnt clean cache

[gusty kestrel]

imagine if vscode happens todo a memory leak when we are on 80 % usage of ram

swap would be working overtime

[covert heath]

mine barely touches swap

max 100M

even though i gave it 16g for some reason

clion was such nice DE

*IDE

[gusty kestrel]

try lazy VIM

[covert heath]

ik

[gusty kestrel]

very lightweight

[covert heath]

already

but i cant seem to wrap my head around it

[gusty kestrel]

you need to be TUI expert to run that shit 😭

[covert heath]

yeah

think it pairs exceptionally with tmux

[gusty kestrel]

which i oddly have

[covert heath]

the point is i dont member everything

and it needs too much configuring (to get single-click experience)

that an ide offers

ig im just a really lazy person

[gusty kestrel]

also i got the habbit of vscode from my school btw

[dull grotto]

https://tenor.com/view/why-persian-room-cat-guardian-but-why-trendizisst-anyaboz-gif-2156104475561014590

[covert heath]

i make 500% profit

[gusty kestrel]

for a better and THOCKY keyboard ofc

[covert heath]

and also creamy

[dull grotto]

Good enough

[covert heath]

the old one was double clicking like hell

actually

triple clicking

[gusty kestrel]

are scissor keyboards bad?

which i use

[covert heath]

idk

[gusty kestrel]

both laptop and my PC

[covert heath]

i personally somewhat enjoy them

[dull grotto]

The only guy who thanked Clankers for RAM-a-acopalyse

[gusty kestrel]

lot of people say they are "less durable"

[gusty kestrel]

business?

[covert heath]

maybe they fly off?

the keycaps

and yeah, if you are not careful

they are ofc somewhat fragile

[gusty kestrel]

i dont think so, my laptop is 6 years old, and still has everything intact

[covert heath]

typing habits also

[gusty kestrel]

my PC's keyboard which is scissor is also been around for 3 years

[gusty kestrel]

i type crazy fast

[covert heath]

mine not so fast

best i can do is 80wpm

[gusty kestrel]

same, around ~60 to ~80 avg

also thats when it pure words

[covert heath]

yeah

[gusty kestrel]

no numbers and no punctuation

[covert heath]

but i think its a bit biased

since most typing test are just strings

[gusty kestrel]

indeed

[covert heath]

and our like is programming

and guess that

they no include !@#$%^&*()_+-=<>,.?/:;"'{[]}|\

~`

[gusty kestrel]

i have a horrible habbit of typing semi colon

like once i did that in pyython

like alot

[covert heath]

RELATABLE

[gusty kestrel]

and kept wondering why was the interpreter screaming lmao

[covert heath]

peak python moment

[gusty kestrel]

lmafao

[covert heath]

python is great language though ngl

at least for scripting

[gusty kestrel]

i'd agree

tho i don't like indent oriented langs

[covert heath]

its unatural

to not be able to type how you like

and your style gets defined by the interpreter

[gusty kestrel]

i'm very used to braces

[covert heath]

very

[gusty kestrel]

i dont use use indented control flow in C too

even tho C supports it

[covert heath]

so literally ```c
if ()
foo();

[gusty kestrel]

tho still if i was made to choose ANY other programming lang except C, it would be python ngl

[covert heath]

also just discovered sth interesting

kthread_create() is extremely quick

but kthread_run() takes 5s for 512 task

[gusty kestrel]

Aerosync?

[covert heath]

yeah

[covert heath]

which is a nightmare

[gusty kestrel]

what does the run do?

enqueue?

[covert heath]

void __no_cfi wake_up_new_task(struct task_struct *p) {
  struct rq *rq;
  int cpu = p->cpu;

  if (p->sched_class->select_task_rq) {
    cpu = p->sched_class->select_task_rq(p, cpu, WF_FORK);
  }
  set_task_cpu(p, cpu);
  rq = per_cpu_ptr(runqueues, cpu);
  irq_flags_t flags = spinlock_lock_irqsave(&rq->lock);

  p->state = TASK_RUNNING;
  activate_task(rq, p, ENQUEUE_WAKEUP);

  if (p->sched_class->check_preempt_curr) {
    p->sched_class->check_preempt_curr(rq, p, WF_FORK);
  }

  spinlock_unlock_irqrestore(&rq->lock, flags);
}

so yeah

its likely the scheduler fault

[gusty kestrel]

WHY SPINLOCK? 💀

[covert heath]

its not a global lock

[gusty kestrel]

Still...

[gusty kestrel]

i suggest commenting those lock and unlock statments and re test

also use atomics here NOT spinlocks

because you are only changing few states

[dull grotto]

Depends on activate_task() implementation

[covert heath]

sched/fair.c modify the entire rbtree

locklessly (mostly)

[gusty kestrel]

you are still wraping it under the lock

by the run function

also did you try without locking?

[covert heath]

its basically the same

[covert heath]

ok my kernel is kinda cooked

and i dont know for sure which commit

so i may have to defer and roll back the release

the vtd module is crashing

on android qemu things are worse

[gusty kestrel]

porting the AxeialOS print formatter and loggers

[gusty kestrel]

IT SPEAKS, IT FUCKING SPEAKS

Also 11 stars noice

Modularus: A Self-Bootstrapping Kernel.

Thats better

[gusty kestrel]

fire

we got modules loading !!!

Insane

[gusty kestrel]

Pushed!: https://github.com/VOXIDEVOSTRO/Modularus

[covert heath]

12 stars is insane

[gusty kestrel]

indeed

[covert heath]

anyways

switched to fedora

[gusty kestrel]

arch to fedora?

not bad

[covert heath]

KDE to GNOME is the point

lets talk in the vc

[gusty kestrel]

Putting the final piece of the Modularus core, THE BUILTIN LINKER

which means NEXT we would have a our core completed !

[covert heath]

that is insane

[gusty kestrel]

indeed

[jade narwhal]

nows 13 :3

[gusty kestrel]

surpassed Aurora OS :3

[jade narwhal]

modularus having more stars than axeial is insan

[gusty kestrel]

AxeialOS has 8

[jade narwhal]

yea
modularus has more than axeial
insan

[gusty kestrel]

Uniqueness of the project ig

[jade narwhal]

does modularus have a discord server

[gusty kestrel]

No? the axe_in_the_leg

is the only one

i've made a poll there

[jade narwhal]

oh right

[gusty kestrel]

insane, i've been building Modularus for almost the entire span of my vacation 😭

[shy pulsar]

i have made like 10 LoC worth of changes to my kernel in this year 😂✌️

[jade narwhal]

axeial ded

[viscid locust]

Lol

[gusty kestrel]

That's some serious dedication \s

also i think Modularus is a KLS (Kernel from scratch). do you think so

[gusty kestrel]

but i don't think so that's the case because KLS doesn't describe what it does, like you are making your first kernel and what you doing and making is technically a KLS

[viscid locust]

What defines a kernel-from-scratch?

[gusty kestrel]

making it from scratch, obviously

coding yourself

[viscid locust]

Well then every non-ai kernel is a KLS.

[gusty kestrel]

exactly.

[viscid locust]

So what was your question then?

[gusty kestrel]

I thought naming Modularus->KLS would be a great idea until i realized that means completely different thing and not relevant to the purpose of the project

[tired maple]

🫡

4 stars

[gusty kestrel]

thanks

[tired maple]

np

how did you achieve 13 stars on this thread??? 🤲

[gusty kestrel]

idk, i guess the activity? and the project itself?

[dull grotto]

https://youtube.com/watch?v=7s664NsLeFM

[gusty kestrel]

because this post is active

[tired maple]

yeah, fair enough, the project is nice tho

[gusty kestrel]

ts can't be more real

[gusty kestrel]

thank you

[gusty kestrel]

HOLY

@wooden linden, Binbricks are alive

[wooden linden]

yooo

[gusty kestrel]

insane

ALSO THE CORE IS MINIMAL ASF

only a VFS, Sysfs++ as root, builtins for loader (uses bootloader request), linker and a static pool!

[wooden linden]

do you plan on an i686 port?

[gusty kestrel]

THATS IT

[gusty kestrel]

maybe? tho that would need some arch porting

as currently i'm working with x86_64 at default

[wooden linden]

im working on a MB2 pre kernel thing that will give a much nice interface and map the kernel in the higher half and stuff

• public domain & i wana make sure it works for others things too

[gusty kestrel]

Multiboot2???

well not bad

[wooden linden]

yes

[gusty kestrel]

i've used it, and ITS PAINFUL

[wooden linden]

it dosnt do alot. so im making a thing for it to be less painful

[gusty kestrel]

very cool

[gusty kestrel]

btw PUSHEDTHE CHANGES: https://github.com/VOXIDEVOSTRO/Modularus

oh my god my excitement is crazy

[jade narwhal]

it's just your code editor freezing it's february

[gusty kestrel]

Spiced up the kernel config header btw
https://github.com/VOXIDEVOSTRO/Modularus

very nice

also more options on BuiltIns

[gusty kestrel]

Added more options to the run script
https://github.com/VOXIDEVOSTRO/Modularus

[gusty kestrel]

finally the linker node

[gusty kestrel]

ALSO fixed the loader

Builtin one

because i forgot to make accept name of the module and actully load the module we want

THIS IS SO FIRE

and this everything would happen from a VFS is crazy

[gusty kestrel]

nah i'm gonna stick with a COMPLETE fork copy of a linux errnos

I think it works

[covert heath]

a linux errnos

[covert heath]

great idea btw

use it too

[gusty kestrel]

cool

also gonna make a distro out of this core

gonna be peak

[covert heath]

i hope this is the last time i see this message

[viscid locust]

nice

[viscid locust]

lolol

[gusty kestrel]

nah, the core is gonna be constantly be updated, optimized and few tiny changes

will be made

[covert heath]

ok

i thought you gonna abandon this one

lmao

[gusty kestrel]

hell nah, Also AxeialOS is also not ded, will be rewritten but with the modularus kernel

[covert heath]

cool

[gusty kestrel]

also the fact this is a 16 day old kernel 😭

it's insane

well obviously because the CORE is under ~8KLoC

and barealy has features on its own

[viscid locust]

Well you copied quite a bit

[covert heath]

nah

[gusty kestrel]

[covert heath]

not as much as mine

[gusty kestrel]

yes the entire VFS from the AxeialOS

[viscid locust]

Not gonna talk about AuroraOS.

dont even mention it

[viscid locust]

how much do you have

[covert heath]

total 74kloc raw c

iirc

[viscid locust]

Damn you got more than me

[covert heath]

and 25k is uacpi

[viscid locust]

I only got like 30k

[gusty kestrel]

and the fact VFS is like ~5KLoC HERE 😭

[viscid locust]

Dont include dependencies.

[covert heath]

and A LOT FROM LINUX

[gusty kestrel]

same for AxeialOS

[viscid locust]

The line estimate should be your code.

[covert heath]

yeah i should strip it a bit

[viscid locust]

with or without dependencies.

[gusty kestrel]

Only the Kernel ./Kernel

[covert heath]

shouldnt be a lot

[gusty kestrel]

Pure C code

[covert heath]

just a kernel tho

[viscid locust]

how much do u reccon-

[viscid locust]

same

[covert heath]

yours and mine is day andnight in terms of features

especially userspace

[viscid locust]

huh?

[covert heath]

what

[viscid locust]

i only got like bash

if even that

[covert heath]

mine dont even have working userspace

[viscid locust]

how many lines without deps

[viscid locust]

ohh

[covert heath]

wait me a min

[covert heath]

i focus on working kernel first

i mean kernel space

[viscid locust]

well what do you really need tbh

vfs

memory

some basic io shit

some sort of basic ahh round robin scheduler

[gusty kestrel]

Same, for AxeialOS i focused on kernel completion

[viscid locust]

nice

how is Modularus going btw

[gusty kestrel]

Modularus only has a VFS, a interactive Pseudo filesystem as root and few builtins THATS IT

you should

you can still do it

[covert heath]

and it takes like 10 minutes to find it

[wooden linden]

you can still do it on mobile

huh ok ig

[covert heath]

on screen kbd

[gusty kestrel]

Ig, i think 100% yes, i must make one

[covert heath]

so its a bit harder

or anything similar

[viscid locust]
