stanix OS

[feral surge]

which mean i should probably add multithreading at thecsame time

[wintry crag]

ic

[feral surge]

uhhhh

i have so much issues with locks

should i disable interrupt on mutex ?

[lapis ocean]

On spinlocks you disable preemption and maybe interrupts depending on when the lock will be taken

[feral surge]

mmm.. and what if i use mutex everywhere

the only place where i use spinlock is in the mutex itself

[lapis ocean]

Blocking mutexes you dont need to disable interrupts

[feral surge]

mmm.. so maybee i shouldn't use mutex for things like the proc state

cause an irq can happend

and the trigger premption

and then the premption itself try to acquire lock

[lapis ocean]

Which would block and the other thread would run

Are your mutexes a spinlock or something

[feral surge]

no my mutex are blocking mutex

wait

but blocking use mutex

what i have done

[feral surge]

okay let do like everyone else

spinlock disable irq

also this make me feel like i should use spinlock for proc state

[feral surge]

seem like the new scheduler don't work

but it's getting close

there is just a race condition somewhere

[feral surge]

i think the problem is unblock_proc being not safe

cause it don't disable interrupt

[feral surge]

first boot with new scheduler

tomorow i can start working on multithreading

[feral surge]

made some progress on multi threading

i can in theory create new thread now

but waitpid don't work anymore

and the thread system don't do cleanup

tomorow i need sleep queue and separate kill_proc from kill_thread

and then i can get some basic pthread and even SMP safe waitpid

[feral surge]

okay

sleep_queue is hella hard

😭 cause i need to be able to sleep on multiples queues

[feral surge]

i hate SMP and multithreading

[wintry crag]

me too bro, me too

[feral surge]

HOW DO I SLEEP ON MULTIPLES QUEUES 😭

[wintry crag]

join me on the single global queue side 😔

[feral surge]

uh you don't understand

i mean sleep queue

[wintry crag]

ah

[feral surge]

so like wait you waitpid you a process grouo you can sleep on the queue of each process

[wintry crag]

yea ok ic

[feral surge]

stanix boot now

with kernel multithreading

next is providing some userspace interface

with clone syscall

and also make waitpid kill and stuff accept tid

and task cleanup ofc

this is gonna be hard

also some stuff are not multithread safz

[feral surge]

tomorow i'll be back

[feral surge]

kinda working multithreading

[hearty shale]

stanix is back!!

[feral surge]

yes !

now i need to finish cleanup

and do pthread_join

and see what mesa need to run

i think pthread_kill shoud be easy since i already have signal

[feral surge]

sleep and signals don't work anymore actually

multithreading introduce a lot of shit

😔

also i need to do thread cleanup when main thread die

so much to do

[feral surge]

STANIX IS BACK

new scheduler now has signal support

tomorow i'll try fixing pthread_join

[bronze zenith]

welcome back

[ruby thunder]

Welcome back

[feral surge]

finnaly fixedd

this work using pthread_join

next is mutexes

[feral surge]

shutdown command + refactoring done today

[feral surge]

compiling and running a program on stanix :

my getopt is kind of fucked

[feral surge]

its fixed

and i have d_type on dirent now

[feral surge]

i think i'm going to make a new proper bus system

[feral surge]

umount done

[feral surge]

utf8 work

[feral surge]

automount work now

i might want to do actual part cleanup when i unmount it

soon i will start sockets

to get a GUI later on

[feral surge]

i started doing unix socket and well its harder than i tought

i really need a lot of refactoring to fit my new philosophyes also 😭

[feral surge]

doom saves are faster thanks to the new caching in my libc

and well progress on socket stack + unix socket

socket stack is praticly finished

unix socket are well pretty hard

[feral surge]

socket syscall moslty done

just missing socket opt and getname shit

oh anf shutdown

and well unix socket are veru buggy

i can'g bind a fucking address 😭

[feral surge]

so uh

socket stack is 100% operational

outside some minors function with no impl it work

but unix socket is still buggy

i can bind and listen

but connect and accept get stuck

[feral surge]

send/sendto recv/recvfrom wrapprr

that all

unix socket still fucked

[feral surge]

cleanup of unix socket work

and did some changes to the tmpfs that now nativly support socket

[feral surge]

devices are now normal inode

and not hacky mount point

so i can chmod/chown them

[feral surge]

working unix socket

[feral surge]

a bit of refactoring + working on something cool

[feral surge]

i think i might got a pretty good bus system

[feral surge]

vfs going trought a rewrite

this is so hard

so much things to rewrite

[feral surge]

i got the core kernel to compile

but the devices don't work perfecly

next is open flags + finshing devices +bringing back /proc /sys and pty

[feral surge]

mmm... now the kern should boot until userspace now

[feral surge]

i got the OS to boot

and even go in userspace and launch a shell but pty are kind of broken

[feral surge]

dev restart today

[feral surge]

new vfs work !

[feral surge]

stanix is one year old today

[ruby thunder]

Wowsie! Happy birthday stanix.

[feral surge]

thx

[feral surge]

no dev for this week

[feral surge]

the entire terminal emulator has been rewritten

[feral surge]

so now the terminal emulator run nyancat without any problem

i still need to bring back utf8 support

[feral surge]

top tier gui

[feral surge]

trying to do modesetting

[feral surge]

i now have a pretty complete info command

[feral surge]

i got framebuffer abtsraction that it

[ruby thunder]

What do you mean with that?

[feral surge]

i have an abstraction layer over framebuffer

i do not use limine struct anymore

and instead i just do generic framebuffer operations

[ruby thunder]

aha.

[ruby thunder]

this question is prob stupid but why?

[feral surge]

this will later allow me to add another framebuffer implementation using TRM (my DRM-like video api)

[ruby thunder]

Nice!

[feral surge]

the partitions system is back

[feral surge]

i started doing a new shell

[feral surge]

look at this beautiful AST

i need subshell $( ) and redirections to work

[feral surge]

got cursor to work

[feral surge]

okay tash2 is ready

it has all standard loops (for while and until) if else elif stament, pipes, process group (with { ; }) subshell with ( ) bracket expansion, quote, break/continue, ...

so it's more than the old one

and can replace it

[feral surge]

the new shell is operational

[ruby thunder]

Does stanix run on multiple arches?

[feral surge]

no

aarch64 and i386 are really just stub sadly 😭

[ruby thunder]

lol

[feral surge]

some day maybee

[ruby thunder]

Hopefully someday.

[feral surge]

but at least now i have a really powerfull homemade shell

[ruby thunder]

cool

[feral surge]

probably one the most powerfull out there
not a lot of people make shell

[ruby thunder]

im still battling scheduling issues caused by reworking my whole os lol

[feral surge]

scheduling 😔

[ruby thunder]

most ppl (including me) will just port bash lol

[feral surge]

yeah writing a parser for shell is pretty hard

the syntax is so shit even yacc cannot generate a complete parser and lexer for it 💀

[feral surge]

i'm on my 5th shell btw

[feral surge]

gl, i hope you don't run into too many race conditions

[ruby thunder]

💀

[ruby thunder]

ehh rn it triple faults as soon as i jump into a thread lol

[feral surge]

yeah it's so fucked

[feral surge]

oh wow

[ruby thunder]

i like how this didnt happen before the rewrite and the rewrite didnt even touch sched and proc code

[ruby thunder]

5th, are you mad????

[feral surge]

each time it gey better and better

let me give you a list of some features

quote support
if/else/elif statements
for/while/until loops
pipes
&& and || support
subshell with ( )
command groups with { xxx ; }
tilde expansion
variables (assignements, temporary environement variables and expansion)
redirections (only on commands

i also have continue/break and other stuff

also

on some script i'm faster than bash since i do not have all the non posix stuff bash has (like array)

[ruby thunder]

nicee

would only wish to be close to be able to do smth like that

[feral surge]

now all features of tash work on stanix

[ruby thunder]

Niceee.

[feral surge]

today i just did some refactoring

not much improvemenr

tomorow maybee mmap tmpfs files + mutex and lock in vfs

[feral surge]

i got mutex to work and some very primitive locking in vfs

tomorow is probably vector impl in kernel + page cache

[feral surge]

i actually need need more stuff to do a page cache

so going to do CoW tomorow

[feral surge]

no dev tomorow

and after tomorow too

[feral surge]

pmm refc count kind of work

and i got new mmu to work

so i can start to work on CoW

[feral surge]

i got CoW to work

next is seg spliting

a bit of refactoring on arch abstraction

and ofc page cache

the main reason i do all of this

[feral surge]

i'm fixing race condtions and doing rwlock

i need that for locking segs

[feral surge]

the new scheduler is hella broken

[feral surge]

scheduler fixed

• new sync primitives

• a bunch of race conditions fixeds

[feral surge]

no regression now

it's time for rwlock and page cache !

[feral surge]

rwlock done

i'm making a page cache

[feral surge]

making progress on the page cache

[feral surge]

the goal is to get an async capable page cache

and then get an async api in vfs

but this probably require to be able to register callback in sleep_queue_t

[feral surge]

most of the page cache api is done

[feral surge]

progress on page cache and new tmpfs

i have some peoblem where it reread places

[feral surge]

the page cache work and i can mmap files

[ruby thunder]

ooo mmaping files has been on my radar for a while now! Well done, was it hard implementing?

[feral surge]

not that hard actually

the hard part is the page cache

once you have CoW and page cache you really just mmap the cache

but i'm actually still missing two thing
cache evict
and mark cache as dirty on unmap/msync

[feral surge]

i now map anonymous mapping as copy on write

[feral surge]

/proc is back

and with new stuff

[feral surge]

i fixed the double unmap bug

and now multithread work

[ruby thunder]

cool

[feral surge]

now i'm trying to do futexes so i can add pthread_mutex and get -pthread option on gcc

[ruby thunder]

multithreading has been a hassle for me tbh.

[ruby thunder]

yea... I should also do futexes tbh.

since mlibc depends on them.

[feral surge]

oh right mlibc

i just wrote my own libc, way more pain

[ruby thunder]

yea

[feral surge]

but hey, it "work"

[ruby thunder]

well im having whatever abnomation this is:

[feral surge]

assertLibC

[feral surge]

i think it try to set gs/fs

[ruby thunder]

same

might have to try and endure whatever pain archctl will give me

need to have it to run bash ig

[feral surge]

it's pretty simple actually

just a few wmsr and ofc saving it on task switching

[ruby thunder]

it was actually quite simple

already had quite a big part of the logic

[feral surge]

that is the new todo list

for the kernel

• evict page
• slab allocator
• inode/dentry cache
• flush page cache
• better blocking system interuptible/uninteruptible, sleeping on multiples queue and time out (with block_until/block_timeout)
• make fat use new page cache

[feral surge]

the slab allocator work !

[feral surge]

trying to make a dcache

[feral surge]

dcache work

and now for cwd i can just store a vfs_dentry_t

which allow me to get an inode for it

but also get back the path needed to open it

here the getcwd impl is just a wrapper around vfs_dentry_path

[feral surge]

i'm changing a lot of vfs operations

[feral surge]

the dcache now work

and i've started a new sysfs

[feral surge]

one binary for all commands !

[feral surge]

the vfs is becomming a 1000 lines file 💀

might have to make it multiples files

[feral surge]

fat with dcache

i brough back automount

now i can do some refactoring on fat and do writing

[uncut kernel]

what disk driver you have

[feral surge]

for the moment just ATA 😭

[feral surge]

i'm trying to add lfn support

tf why is it so hard

i might straigh jump to ext2

[feral surge]

doing some refactoring

then i can continue on more basic stuff (permission checking, safe user copy, and fix some race condition)

[ruby thunder]

race conditions everyones favorite

[feral surge]

i've got permission checking in vfs

and now user can only get info on their own processes

[feral surge]

fwrite was broken

i fixed it

now tcc work !

[feral surge]

after too days of work i got the new dynamic linker to compile and gcc to compile with shared library support

so now i have libc.so and libm.so

next step is trying to see if it work and add interpreter support to the kernel's elf loader

so i don't have to /usr/lib/ld-tlibc.so myprogram each time

[ruby thunder]

Ohh you didn't have that before??

Or well everything is so easy with mlibc

[feral surge]

i don't use mlibc

i use a homemade libc

[ruby thunder]

that's what I mean

I'm spoiled

[feral surge]

nop, static linking was enought

but now i want it

it will be easier to load opengl this way

[ruby thunder]

True

You should maybe port sdl2?

[feral surge]

yeah i'm also trying to port sdl3

but for mesa and sdl3 the big problem is the same

i'm missing a lot of pthread stuff

[feral surge]

my dynamic linker has some relocs 😭

trying to eleminate as much as i can

[limpid gust]

:(

[feral surge]

i've removed 3 out of 10

once i remove them all i get dynamic linking !

wich will reduce memory usage

since if two process use the same library i can just mmap the library to map the page cache

[limpid gust]

letsgooo

[feral surge]

i removed all relocs from the dynamic linker

and got pretty far

sadly it has a weird bug where it try to write it's own stack

[limpid gust]

RIP

also is that bash?

[ruby thunder]

tash

https://github.com/tayoky/tash

[limpid gust]

oh

https://cdn.discordapp.com/attachments/1132341895717208116/1475556674600435773/61d.gif

fair enough

[feral surge]

it's tash, a homemade posix shell

[limpid gust]

how easy is it to port

[feral surge]

pretty simple really

[limpid gust]

c library?

[feral surge]

you need basic stuff (open/write/...) termios and basic libc stuff

[feral surge]

ofc

[limpid gust]

termios

[feral surge]

it's meant for unix like OSes

[limpid gust]

fair

mine might be literally anti unix like

might have to write my own shell idk

or port a stdc and use bash or smth

[feral surge]

well my goal is to be able to run the configure script of stanix and gcc on stanix itself (for self hosting)

so i need a unix like shell

[feral surge]

some stuff can probably be stubed but this is what it need : abort chdir close closedir dup2 environ execvp exit fcntl fflush fork fprintf fputc fputs free getchar getcwd getenv geteuid getpgid getpid getwchar ioctl isatty localtime_r malloc memcmp memcpy open opendir pipe printf putchar putenv puts putwchar read readdir realloc setpgid signal snprintf sprintf stat stderr stdin stdout strcat strchr strcmp strcpy strdup strerror strlen strncmp strndup strrchr strsignal strtol tcgetattr tcsetattr tcsetpgrp time ungetc vfprintf waitpid

for exemple opendir is needed only for globing/auto completion

or signal/strsignal is needed only for job control

[lone jay]

yo is that bash

[limpid gust]

[feral surge]

it's tash, my homemade posix shell

[feral surge]

^

[feral surge]

finaly got dynamic linking to work

but i have some issues with environ

[uncut kernel]

are you doing own libc

[feral surge]

yes

but since it want to use a copy reloc with environ it's annoying

[feral surge]

mmm... made some progress

but global variable from libc (stderr, environ, ...) still not work

[feral surge]

fixed !

dynamic linking work

[feral surge]

btw

my new text editor

tvi

a vi clone

[crystal kestrel]

looks good, when syntax highlighting?

[limpid gust]

syntax highlighting is comically complex ngl

idek

you either hard code it or you write like a parser for insane syntax files

[feral surge]

i will load modules using my new dlopen ! :D

[limpid gust]

or that

[feral surge]

here it is

[crystal kestrel]

nice

[feral surge]

i have a few small issues

since dynamic linking tcc does not work anymore

and strdup is broken in my GUI WTF

[feral surge]

i got tcc to work with dynamic linking

and mesa to compile a bit further

[feral surge]

trying to get auxv

dynamic linking sometimes crash now 😭

[feral surge]

fixed

nod it's time to fil auxv with interesting stuff

[feral surge]

ls running with dynamic linking

[dawn meadow]

Cool

Is this your own libc?

[feral surge]

yes

my own libc

my own utils

my own shell

[uncut kernel]

make own x11

[dawn meadow]

Cool

[feral surge]

i will

[feral surge]

i got + - = and ? on parameter expansion on shell

[feral surge]

i'm getting pretty close to quake2

[ruby thunder]

Looks fire

[feral surge]

i'm starting to make a GUI

here a window with the terminal running in it

no input, window moving or resizing yet

[uncut kernel]

why not to just port xorg

[feral surge]

i want to make my own window manager and api :D

my final goal is to make everything by myself

[uncut kernel]

then do x11 protocol

to launch some cool stuff in future

[feral surge]

well i don't really want to port any x11 app

ane i can just port SDL and glfw to get the few things that i want

[feral surge]

i'm making layout files

[feral surge]

now i have layout files !

azerty for exemple is ```# use qwerty as base
include qwerty

0x02 & 1
0x03 é 2 ~
0x04 " 3 #

[feral surge]

now i'm working a GUI

[left gyro]

good luck !

[ruby thunder]

from scratch as usual?

[feral surge]

yes

[feral surge]

it look ugly and is pretty slow but it work

[ruby thunder]

Ugly???

That looks good

[feral surge]

oh thanks

[feral surge]

doom work in windowsed mode

[ruby thunder]

what is ur gui library built upon?

[feral surge]

it's made from scratch

and for the moment is not used in stanix

[ruby thunder]

so its not based on ex SDL2

[feral surge]

no

it's inspired by GTK and css that all

[feral surge]

i can close windows now

and i fonally got the gui lib to work on x11

now i have to make it work on stanix

[left gyro]

gg

[crystal kestrel]

You may need to upgrade your version of Doom to v1.9

[feral surge]

i'm working on a GUI lib

[crystal kestrel]

X cursor

[feral surge]

here a grid widget with buttons widgets inside

[feral surge]

not enougth place to install a window manager

[feral surge]

i need hexpand on grid

[feral surge]

i'm getting close to a working calcualtor

[feral surge]

better widget that expand

[feral surge]

i'm trying tl rewrite poll

got a few stabity issue with the new poll

[lone jay]

is the window manager also opensource?

or wel

where is the window mangaer

[feral surge]

yes

everything is open source here

[feral surge]

new poll finally work

only timeout is missing

and we should be good to go on something else

like finishing tgui

[feral surge]

trying to do rounded rects

[ruby thunder]

Hey, is the source code of your VM in any repo, need some inspo for my own VM.

[feral surge]

you mean WM ?

[ruby thunder]

Ohh shit my phone autocorrected it.

[feral surge]

i mean i made a very small 8086 emulator but it's not really a complete VM

[feral surge]

it's in the main stanix repo

curently going trough a small rewrite to let clients draw their own titlebar

[feral surge]

i got it to work next is making the thing faster and getting a logo for stanix

[feral surge]

okay much better

[feral surge]

improving gui lib with fancy things

like menus

[ruby thunder]

Fancy

[feral surge]

lspci is back

[dawn meadow]

does it handle multiple pcie roots?

[feral surge]

it's just a userspace programm

it does not direcly interact with hardware

and well the kernel's pci driver does not even handle pcie

[dawn meadow]

ah

[feral surge]

i just have a /sys/bus/pci where pci addresses are exposed

[dawn meadow]

are u also doing linux abi?

[feral surge]

no

[feral surge]

making progress on UI

[ruby thunder]

Cool!

[feral surge]

thx

i need to bring back doom to new ui

since decorations are now client side

i also fixed the close button so now it's the same size

[ruby thunder]

How optimized is it btw

And do you plan to make an xorg compatability layer, or just port SDL, GLFW etc

[feral surge]

without logging it work great

but it could be optimised more i think

[feral surge]

i'll just port glfw and SDL

[ruby thunder]

it can always be more optimized

[uncut kernel]

🔥

[feral surge]

working on taskbar :

[feral surge]

the popover system is close to complete

[feral surge]

popover menus work

[uncut kernel]

make these things smaller

[feral surge]

the icons ?

[uncut kernel]

this bar

its high

[feral surge]

the bar has the minimum height with padding and size of icons

to make thz bar smaller i'd need smaller icons

[feral surge]

i got a scrolled window widget

and now i can scroll anything !

for exemple here i can scroll text horizontally

[feral surge]

i got a working dynamic list view

[feral surge]

working on start menu

but i'll have to stop for 3 days

i'm going on vacation

[feral surge]

getting closer to compiling doom on stanix

[ruby thunder]

You got gcc ported?

[feral surge]

no i'm using tcc + binutils

and make ofc

and tash, my own shell

[ruby thunder]

ohh

cool

[feral surge]

i think the seg fault actually comes from tcc

since i picked a non offical releasz

[ruby thunder]

Ohhh

[ruby thunder]

why 😭

[feral surge]

so i'm going to port another version and see

[feral surge]

the last official release was in 2017

[ruby thunder]

ohh

how hard is it porting normal gcc

wonder

well for you it might be quite hard

as you make everything by yourself

[feral surge]

apparently not that hard

i might try

the only issue is that compiling gcc takes so long

so i didn't do it for a long time

but now i have dynamic linking so i should be able to modify and libc and retry without recompiling gcc

so i might try tomorow

[uncut kernel]

its not hard

[feral surge]

i think you just need a decent libc

[ruby thunder]

might try

im bored anyways

ohh astral has a port that i can steal

well then its not hard at all lol

[ruby thunder]

fair, how is tlibc going btw

[feral surge]

pretty good

i have enought for most stuff i want to port

at this point the biggest issue is bugs in kernel

and GUI lib

not even the libc

i have reach around 400 funcs implemented in tlibc

[feral surge]

doom, but compiled from with in stanix

[ruby thunder]

Cool!

I'm porting gcc right now so ima try and do it too

shouldnt be that hard right

Is make a pita to port or is it easy?

[feral surge]

make is extremly easy to port

you only need to be carefull for envp

the actual signature of main is not int main(int argc, char **argv);
it's int main(int argc, char **argv, char **envp)

[ruby thunder]

Just got binutils working so now i just gotta do gcc

And then im fine

[feral surge]

gl

[ruby thunder]

Thanks

[feral surge]

for some reason libgmp does not want to compile for stanix

[ruby thunder]

I have had a hell with all of these lol

send me the error if ya need help

im stuck at gcc being stupid rn

[feral surge]

this is it

GMP does not even declare it'own funcs flr some reason

[ruby thunder]

huh

sounds like something wrong at configure

gmp messes with many internal macros

[feral surge]

idk . I just did ./configure with a few options

https://github.com/tayoky/ports/blob/main/ports/gmp/gmp.sh

[feral surge]

basicly the same except i didn't use --with-sysroot

[uncut kernel]

grep -r __gmpz_inp_str_nowhite

and find what it requires

maybe you didnt implemented something in your libc and configure doesnt like it

[feral surge]

what it require ?

[feral surge]

oh

yea well GMP has quite a lot of macros that it checks your LIBC with, if something isnt implemented it might lead to errors like this

[uncut kernel]

idk usually they are #ifdef with macros like HAVE_somelibcfunc

[feral surge]

but GMP should not need that much

it's just a library for large number right ?

[uncut kernel]

do you want to compile libgmp in stanix or for cross compiler on your host ?

[feral surge]

i'm cross compiling it from linux to stanix

[feral surge]

i'm on my phone rn but i can try that

[feral surge]

wait a minute im I supposed tl run configure in another dir than the sourve dir ?

[ruby thunder]

yea i do that

[feral surge]

might be that

[ruby thunder]

out of tree build works better for me atleast

[feral surge]

even if i sad bananymous not doing it so it should't be the problem

let me configure on my phone and see for the grep -r

[feral surge]

i found the declaration is wrapped into something like this

but it is wrapped inside _GMP_H_HAVE_FILE

what the hell is that

[uncut kernel]

now

look to configure config.log or configure src and find how it detects it

[feral surge]

but i searched i don't find definition of these kind lf contants in config log

oh it's defined in gmp.h

it check if _STDIO_H or FILE is defined

[uncut kernel]

you have FILE right ?

[feral surge]

yeah but not as a macro

[uncut kernel]

do you define _STDIO_H then

in your stdio.h

[feral surge]

no i define STDIO_H

that the issue !

thanks

[feral surge]

so i cross compiled gmp mpfr and mpc

and now i'm trying gcc

[ruby thunder]

Let me know how it goes

[feral surge]

well i had to enable libstdc++ on my cross compiler

and now when i compile it it complain about a missing libgcc_eh.h

idk why

[feral surge]

now i'm onto compiling libstdc++

that so fucking hard

i'm missing toons of math funcs

and for some reason it complains about my types

[velvet sail]

which one

clang?

[feral surge]

the one shiped with gcc

[velvet sail]

ah, well if you are using mlibc you have to add a few symlinks + disable localization

[feral surge]

i'm using my own libc

[velvet sail]

ah

gl then

lol

[feral surge]

thanks 😭

i'm missing mblen

should be easy

it's just mbtowc

[uncut kernel]

its really depends on libc

[feral surge]

yeah my libc kind of suffer rn 😭

setbuf done

step after step we are getting closer

[feral surge]

i got libstdc++ to compile but linking with it is fucked

it does not find symbols with libgcc

[feral surge]

Trying to get libgcc_eh and libgcc_s to work

[feral surge]

I hate libgcc so much

[lone jay]

use clang?

https://github.com/SeeleOS/toolchain

[feral surge]

I don't want to port llvm 😭

[lone jay]

uh

i mean

using clang to cross compile

and im pretty sure gcc is harder then llvm

since i had a lot more problem porting gcc then porting llvm

[feral surge]

I want to use the same for both cross compiling and porting

[feral surge]

Oh what

[lone jay]

idk it might just be im using clang all along

[feral surge]

getting further on running cpp programs :

[feral surge]

i finnally got it (with a few hacks) :

for some reason when i pipe the cpp hello world in a file the newline work :

probably a termios issue

[feral surge]

I'm redoing a lot of vfs and process management

To fix race conditons and memory leaks

At some point i'll need some to evict the page cache too

[feral surge]

The vmm is now free of race conditions i belive

But now waitpid seem to be kind of broken

[feral surge]

i got an xarray impl

and now i use it for proc/task list

[feral surge]

Xarray_foreach implemented

So now i can fully switch to xarray for proc list

I'm also trying to use it for the devices list but it's kind of broken

[feral surge]

fixed

[feral surge]

Unix sockets are fixed and now the GUI work again

[feral surge]

Doing random libm funcs now

Trying to get quake

[uncut kernel]

do you have doomgeneric

[feral surge]

Yes

And quake2 kind of work

Like the menu and thebdemo work

But when i launch a game everything appear at 0 0 0

[feral surge]

quake2 on stanix :

[crystal kestrel]

hell yea

[feral surge]

I inverted red and blue channel

[crystal kestrel]

[feral surge]

fixed

[crystal kestrel]

now that's better

[uncut kernel]

blue looked better tbh

[feral surge]

I now have issues with running stanix on kvm

I need APIC qupport

[feral surge]

I've fixed various vfs issues

[feral surge]

Irq abstractin done

Next is ACPI and APIC !

[feral surge]

I can find ACPI tables now

[ruby thunder]

congrats and well done

[feral surge]

Thanks

But the hard part is APIC

[feral surge]

Now i find local apic and IOAPIC using MADT

But i need a better mmio system first

[feral surge]

APIC now work :

[feral surge]

After some fix to ps2 stanix can boot again on virtual box

But sadly the initrd take years to unpack

Slow tmpfs_write i belive

[feral surge]

long name support on stanix :

[feral surge]

I had a big paging issue that made booting much slower than it should

Much faster now

I'm doing a lot of refactoring and fixing race conditions

Maybee page evict soon

[feral surge]

I fixed so much race conditions in the page cache

Now i only have a few left

And i have a few lru lists of pages in page cache

So i will be able to do evict later on

[feral surge]

The -pthread option finnaly work on gcc!

And now it link with libgcc_s

So i should be able to link with cpp programs

[feral surge]

newline with libstdc+= work now ! :

[feral surge]

Trying to get a shared library so OSMESA can link

[feral surge]

I need to actually implement tons of stubs now

[feral surge]

I need to recompile gcc

😭

[feral surge]

Still working on OSMesa

And improved the UI lib

[feral surge]

mesa work finnaly :

[uncut kernel]

congrats

is this softpipe

[dawn meadow]

hardpipe

[feral surge]

Yes

It somehow work with my custom libc

[dawn meadow]

Are you doing fully custom Userspace?

[feral surge]

Yes

[dawn meadow]

cool

[feral surge]

i changed colors a bit

[feral surge]

Trying to get a sdl port

[feral surge]

no progress on sdl port

it just complain i didn't add a display 😭

[uncut kernel]

when gtk3 port

it shouldn't require too much from libc too iirc

[feral surge]

I would have to write my own gdk backend

[feral surge]

i added server side borders :

[feral surge]

sdl !

[ruby thunder]

cool

[feral surge]

Thx, next step is input and opengl support for sdl

And i'll be able to port raylib i think

[ruby thunder]

Raylib huh.

[feral surge]

Yes

To port a few games made

[ruby thunder]

Which games are u trying to run?

[feral surge]

Games made by friends

For exemple @wintry crag made a small minecraft clone with it

[feral surge]

I got sdl2-compat to work and did a bit of refactoring for my wm library and added support for more stuff to sdl port

[feral surge]

Getting a sdl12-compat port

[feral surge]

a nes emulator on stanix :

[feral surge]

sdl input work now and i have a libarchive port

[feral surge]

quake2 running on the gui :

[feral surge]

Trying to get ffmpeg to work

But i seem to have IO issues

[uncut kernel]

when ffmpreg

[feral surge]

I don't really know

It complain about not finding thr movv atom

Let me show

On my host this video work

So it's really weird

[feral surge]

So uh iproving libc

That all

[feral surge]

I'm going to port my libc to linux

It will be a lot easier to debug

Cause rn i don't know where the ffmpeg issue come from

[feral surge]

Ffprobe work now

[feral surge]

ffmpeg work !
