this will take ages to upload

[hybrid island]

surely you can just make a minimal image bruh

[near tartan]

i already nuked the changes

[hybrid island]

bruh

[near tartan]

bro @spark surge what did you do to flanterm

why is it shit now

:D

i should write an I226-V driver

a zinnia server on real hw + ssh would be fucking funny

[spark surge]

what are you referring to, exactly? speed, the fact that it no longer autoconverts \n to \r\n, or what?

the speed is definitely no WC

[near tartan]

yes

[spark surge]

that's intended behaviour

[grave peak]

Because it emulates a TTY

you kinda have to treat flanterm_write as a serial_write, and any driver even on linux inserts \r for that in the write callback before it goes to the wire

[modern hamlet]

That's not really the behavior I was seeing with flanterm

It always just moved to the next line AND reset the column position on \n regardless of whether \r was present or not

Has the behavior changed?

[near tartan]

yes

[rugged shard]

yes

oi

[near tartan]

i updated it and it did that all of a sudden

[near tartan]

i also do that on com1

but not on flanterm because it didn't do this before

[near tartan]

ok fixed

[near tartan]

i fixed ttys

[somber solar]

zinux

[grave peak]

Did you ssh into it?

[near tartan]

yes

from the phone

it's running on my server rn

[grave peak]

Cool

[near tartan]

so far no crashes

shit

now i need to check on the server lol

rewrite in C soon

the fuck?

[marsh holly]

Mfers in 2026 dont even rewrite their code anymore they just look at claude like this

[near tartan]

fuck my stupid chud life

my allocator so ass 💀

the problem with claude is that it's finding bugs in my trash code left and right

[somber solar]

how is that a problem?

[near tartan]

i keep using it for that

[somber solar]

just don't pay for it anymore :^)

[near tartan]

i won't

i bought it for one month

[near tartan]

i need to revisit all usages of mutex/spinmutex

there are so many stupid deadlocks in this thing

I226-V driver incoming

[near tartan]

i am in the process of rewriting the signal implementation

it was quite bad

for example SIGSEGVs couldn't be caught, it would just terminate regardless

lol

now os-test gets quite far

i also made sure nothing heap allocates in an interrupt

oh and that exposed another polling bug in epoll_pwait()

now the xfce-terminal opens without me having to move my mouse to make the window appear

since zinnia can now reliably boot on real hardware, i think it's time to try to connect to sortix irc on real hardware

[steady echo]

Amazing

[near tartan]

I226-V time

[near tartan]

i did connect to sortix irc on real hardware

usb time

[rugged shard]

technically mbps not mb/s

[modern hamlet]

What's the difference

For physical speed you can say km/h and kmph, or m/s and mps

(Although I haven't seen mps anywhere)

[somber solar]

one is in bits while the other is in bytes

[modern hamlet]

The difference is not in / vs p, the difference is in Mb vs MB

You can see that the b is lowercase in Mb/s

If he wrote MB/s, then yeah, that would be incorrect unless it actually refers to megabytes per second

It's true that Mbps is the common form of the term "megabits per second", but Mb/s is just as valid

[somber solar]

good to know

[near tartan]

Mb/s != MB/s

[rugged shard]

ahh

mb then

[near tartan]

*Mb

[somber solar]

lol

[rugged shard]

mb=my bad

lol

[lofty copper]

Multiboot

[near tartan]

multiboot=bad yes

[idle flower]

milli buckets,
Minecraft

[near tartan]

usb stuff has been started

[somber solar]

how many litres is one millibucket?

[near tartan]

1000

minecraft mods are following SI standards

[somber solar]

based

me casually getting one million litres of milk from a cow

[marble salmon]

me when i carry 27 * 64 * 7 tons of iron blocks

[lofty copper]

Me when I get them from a storage cell via a wireless terminal

[rugged shard]

Me when my turbine engine consumes 64000 liters of kerosene a second

[idle flower]

1L; one cubic meter aka one Block is 1000L = one Bucket

[median forge]

dont forget that this water is endless

[storm bobcat]

Not in gtnh

[eternal wharf]

what always perplexed me is that a bucket is 1000 mb, but then a block of a metal is 9 ingots, but an ingot is usually 144 mb of molten metal

but a bucket is a blocks worth of water

[marsh holly]

1 cell of liquid is 1 bucket UNLESS its a molten metal or plastic, then it is 144 mb

greg logic

[eternal wharf]

i mean the problem is wider than just greg

[cyan nexus]

Or tinkers

[eternal wharf]

or well, it's not really a problem

just something i've been thinking about

[vast lotus]

this actually does make sense if you take into account that density decreases with temperature

melting a block would give you more than a block worths of that material in liquid form

[eternal wharf]

i guess, but then you need to consider that different metals have different densities?

[vast lotus]

that's true

[near tartan]

omfg

my thinkpad has the trackpoint exposed via ps/2

[grave peak]

it probably uses the multiplexed ps2 protocol

where u have 2 ps2 mice

[near tartan]

wdym

[grave peak]

it basically allows up to 4 ps2 devices

[near tartan]

i only have one mouse

[grave peak]

touchpad

[near tartan]

on

no

the touchpad is i2c

[grave peak]

its both probably

[near tartan]

the touchpad doesn't work

only the trackpoint

[grave peak]

oh ok

or well

no

you dont implement multiplexed ps2

so u dont actually know if it works

[near tartan]

i will check in linux

[grave peak]

linux will use in i2c mode because thats what aml exposes likely

im just saying that in legacy ps2 mode u could see one of those exposed

[near tartan]

ig

[grave peak]

because ps2 doesnt allow 3 devs obviously

at least on one of my laptops with a trackpoint i have that setup but idk

[near tartan]

omfg it works

[grave peak]

what does?

[grave peak]

nice

and the kb is ps2?

[near tartan]

yes

LMFAO

i think i messed up the caching mode of the gop or something

I'm getting a solid 1 fps in glxgears

[near tartan]

okay that is fixed

[grave peak]

Whats the number now

[near tartan]

one sec

laptop battery died because i left it on accidentally

note for later

clang somehow creates a textrel dyntab entry on a hello world

@grave peak

xfce is not a fan of me moving the trackpoint

whenever i do it freezes glxgears

this should be running with smp too

yeah

this is so cool

i think this is a good picture to put on the readme :D

[median forge]

move closer to the screen

[near tartan]

no

i want to show that it's running on real hw

[grave peak]

Nice

[near tartan]

@fair lintel btw

i saw your msg in unmapped

(it was caching)

god damn it

@hoary cave isn't this the same place where your thing gets stuck?

is your pc amd by chance?

[hoary cave]

i have an intel pc lol

[near tartan]

bruh

[hoary cave]

but yeah looks similar

[near tartan]

hm

[hoary cave]

i dont see the rtc print

[near tartan]

might just be initgraph ordering

[hoary cave]

i only see fbcon and discover ap ones

[near tartan]

because i recompiled

[hoary cave]

but yeah

is that ur machine?

[near tartan]

it's my epyc server

[hoary cave]

good

fix it there

and then it'll work for me

👍

[near tartan]

👍

[hoary cave]

:D

[near tartan]

look at ts

[hoary cave]

cool shit

how input?

[near tartan]

ps2

[hoary cave]

wtf

[near tartan]

it's emulated

[hoary cave]

bro has working ps2

no astral curse

[near tartan]

i finally figured out what broke rust std

i was missing fields from mlibc pthread attr

[fair lintel]

the fuck

[near tartan]

so it was backtracing into undefined pointers

or well, my test program was

but it works now

so in other words

yet another abi mismatch

and i can almost use clang now as well

[near tartan]

just this problem

[marsh holly]

Funnily enough it seems to work fine on asstral now

Not that its even of as much importance anymore with usb hid

[near tartan]

But for the time being I have a small box with a screen, ESP32 and an ICE40

[marsh holly]

[hybrid island]

who knows

We'll see I guess

[marsh holly]

I have a feeling the mod of that subreddit has me deboosted or some bullshit because I complained to him once

[brisk totem]

lol

[near tartan]

reddit mod behavior

oh fuck me i need to fix the website

💀

[hybrid island]

can mods do that?

[marsh holly]

Idk

[shy turret]

Why not use r/osdev2 aswell?

I mean like it exists for a reason

If it gets content it helps

[near tartan]

reddit is a lost cause

i passed the vibe check

[somber solar]

I ruined my entire history like 2 months ago so the older commits all have that same creation date

when in reality I started the rewrite like in december of 2024

[near tartan]

@hoary cave i think i fixed the discover-ap hang

i was reading the MADT wrong

idk how this code ever worked

but basically i was reading beyond the end of the table and looping infinitely if it happens to be zeroed out

[hoary cave]

good job

[near tartan]

riveting i know

i'll make an image for you

oops

[marble salmon]

btw marvin you should also re-test Managarm master with the usb and ap fixes

[grave peak]

If only there was uacpi_for_each_subtable

[near tartan]

boring

[grave peak]

Tru

Its covered by unit tests and does bounds validation so its super boring

[near tartan]

i should have a kernel test suite for the high level aspects 🤔

maybe something like user mode zinnia would be cool

[grave peak]

Yep

[near tartan]

that sounds like a really fun idea unironically

after i get usb hid working i'll definitely try that

@grave peak did you see that one guy hating on zinnia

saying "yet another linux os"

[grave peak]

Anything that doesn't have a custom vibecoded crappy gui is Linux compatible, obviously

[hoary cave]

you can run tests in kernel too

its very easy

[near tartan]

oo

[hoary cave]

with a custom test harness

[grave peak]

Yeah you can make a ktest module for example

[near tartan]

yeah i know about the harness thingy, but i was thinking about something that would work nicely with cargo test/CI jobs

[hoary cave]

the harness does work with cargo test

that's what it plugs into, literally

gives you a slice of test functions you can run

[near tartan]

does cargo get to see which tests fail/succeed in detail?

[shy turret]

Why not have a vibe coded kernel GUI os that is also Linux compatable

[hoary cave]

no, because you are no_std

but you can show the user which tests fail and which pass

you get to implement the frontend

[near tartan]

that's harder to expose then

[hoary cave]

not really, you can just output it over serial bro

[near tartan]

yeah but i need to parse the results from there

[hoary cave]

boo hoo

[near tartan]

[hoary cave]

"i have to write code"

[near tartan]

no that's not what i'm saying

a user mode harness would be cooler

[hoary cave]

i guess, but that's so much more work lol

[near tartan]

i guess

[hoary cave]

and you can't run the tests on real hw that way

but i guess it's not really needed

usermode kernel is useful for other things than testing

[near tartan]

i don't think testing QEMU drivers makes sense in CI

more so the core, vfs and stuff like that

[magic charm]

lmao

standard response of someone who got osmogged

[grave peak]

I don't have a usermode target but for example I just copy kernel sources to the test dir, with some of them being synthetic and just test that way

So like unit tests but as a normal user app

[near tartan]

i would've conditionally declared the kernel as std if testing

then linked it against a portable binary to run the tests

since the kernel is technically speaking just a shared library with an entry point

[grave peak]

Yeah

All you need is a custom phys to virt impl and page table abstractions for userspace

[near tartan]

do i?

if I'm just testing high level code

[grave peak]

Depends on what you want to test

Like im doing a full test suite for all of my allocators for example

Which requires page_to_virt phys_to_virt and basically everything like that

[near tartan]

I'll have to see what it entails

[grave peak]

Just a custom backend that persistently converts a physical page into some malloced memory or similar etc

[storm bobcat]

Yes

Do it

You don't need dhcp for ipv6

[near tartan]

but i want to do it before that

[near tartan]

[shy turret]

Here lies zinnia
You can tell it's zinnia since we put its name on the stone

[near tartan]

i ported git

i really wish porting rustc was easier lol

the toolchain is the worst part of rust

[lofty copper]

Huh

Rustc is easy

[near tartan]

no lol

i'm not talking about a cross compiler

actually running it on the target

[shy turret]

When did git start using rust?

[near tartan]

what?

my rustc rant is unrelated to git

i wanted to compile the kernel on itself

but it's just not working

[shy turret]

oh lol

[near tartan]

i need to add my target to like 10 different crates

[shy turret]

though git was adding rust a while ago
https://lore.kernel.org/git/[email protected]/

[near tartan]

[shy turret]

Ah neat

[lofty copper]

If only Jinx supported conditional patches...

[near tartan]

why would you need that

just write your patches in a way that makes them unconditional

[lofty copper]

Because I disable different stuff for different architectures

[near tartan]

that sounds wrong

[lofty copper]

Like I don't build i8042 for RISC-V for example

Or only build grub image for x86

[near tartan]

but why would you need to patch anything there

[lofty copper]

I'm not patching anything

But it breaks when I have variables in dependencies

[near tartan]

wat

i literally don't get what you're talking about

[near tartan]

you said patches

[lofty copper]

But it's not patches literally

Idk, someone called it that

[near tartan]

im confused

[lofty copper]

Whatever command that the buildbot is calling that gets all packages doesn't resolve the environment variables

And it doesn't work

[near tartan]

it runs jinx dry-run "*"

[near tartan]

yikes

that's a bug ig

but mint isn't available rn

[near tartan]

i'll use this as my test harness, instead of booting a qemu

i invented that

[near tartan]

when did you have that idea

[storm bobcat]

pay me 3 gazillion $

[storm bobcat]

ive been doing that for a year

[near tartan]

i mean it's not entirely a novel idea

[storm bobcat]

i shilled it for a year also to infy

so maybe you were victim of my shilling unconsciously

im not sure how far along you are but https://github.com/rdmsr/zag it's all in um/ subdirectories if you wanna check how I do stuff

[near tartan]

zamn

[storm bobcat]

I can run the entire kernel under um

[near tartan]

i can't

and i don't want to

i just want a barebones CI harness

so i can have tests run without a qemu

[storm bobcat]

it has been insanely useful for me

especially in early development

[near tartan]

how does it work on linux? ptrace?

[storm bobcat]

in fact the first platform was usermode

for what?

[near tartan]

capturing syscall's

[storm bobcat]

I don't do that yet

but yes linux uses ptrace i think

or something similar

AF_PACKET is an okay interface IMO

actually wait

sdhcp works via udp

funny

[marsh holly]

dhcp is just udp and some ioctls/sysctls

[near tartan]

good point, i should implement getifaddrs

[marsh holly]

Do it like gloire's sloperated netstack and have dhcp in kernel

why would you do that

i might slop ipv6 becvause i don't understand how it works myself

but cmon

don't do that

i want to learn it, but i'll just ask where to find the info and the relevant parts

in the rfcs

i'm not reading all of it

[marsh holly]

Then thats not really sloping it

Imo

[near tartan]

it's still kind of slop because i'm using the slop engine

but less slop than gloire

i wasn't even going to touch ipv6 until that person opened an issue asking for it

like i said

[near tartan]

.

I'll look for an alternative maybe

[marsh holly]

Oh ok so you are slopping but like human slop

[near tartan]

💀

i need something that can work with the SIOCGIF stuff

[magic charm]

possibly udhcp

i think that got absorbed into busybox

[near tartan]

hm true

but that'd be the only applet I'd use lol

i already use gnu coreutils

hm

do i bite the bullet and just implement AF_PACKET

then use dhcpcd

oh wait

dhcpd is already portable kinda

[near tartan]

LFG

dhcpcd with a custom backend

looks like it works finally

[magic charm]

that was fast

[near tartan]

well the backend wasn't all that complicated tbh

[magic charm]

i forgot what the dhcpcd codebase looked like but i remember the linux backend looking like a mess

[near tartan]

i'm not using the linux backend thankfully

the patch is about 300loc

most functions i just stubbed

you just need a way to do raw packets

i do AF_PACKET

ironically my internet is 100mbps down

40 up

but my homelab is a rack of 5 machines which need to talk to each other fast

i'm moving all my games to one of them, and my pc just loads them via fiber

sure, my actual internet isn't that fast, but anything that happens inside my room is blazing fast 🚀

[rugged shard]

loading them locally from an nvme would be quite a bit faster still but with 10gbe it doesnt sound so bad

[marsh holly]

eat the rich

[rugged shard]

512gb of packages...

[eternal wharf]

mfw porn in tmpfs

[marsh holly]

Seize the means of computing

[near tartan]

well

i do store all sources, build dirs and build results

[rugged shard]

i mean its fair

yeah

[near tartan]

sure it doesn't need that much

but i had to populate all channels

[eternal wharf]

try building webkit/chromium with -j96

[near tartan]

this is actual server hardware which only takes RDIMMs

[rugged shard]

true

[near tartan]

and you get a benefit of you run all 16 memory channels

[eternal wharf]

i was ooming at -j32 with 64GB

[near tartan]

yeah this server has 96 threads

[eternal wharf]

for webkit i think it was (or qtwebengine)

[rugged shard]

i've never owned any server hardware so yeah

[near tartan]

the Epyc 7443 machine has 48 threads, but a significantly better single core perf

[rugged shard]

my "server" has a literal ryzen 5600 and 16gb of ram

[near tartan]

buy

you can get these server cpus for cheaper than you think

like ~100€

[eternal wharf]

well there's one very expensive piece nowadays

[near tartan]

they're not expensive anymore because they suck balls

it's about as good as a 9950x in MT

[rugged shard]

dedotated wam

[marsh holly]

C++ software is not included in the dataset for skewing the results

[rugged shard]

wtf

[near tartan]

the neat thing about epycs is that you get 128 pcie 4.0 lanes

[eternal wharf]

well it wouldn't be that bad if they didn't do unity builds for parts of it

[near tartan]

i have like 6 full x16 pcie slots here

okay 5

I can't count

[rugged shard]

ig the nvmes take up a bit

[near tartan]

no they have their own slot

and you have an mcio port for that

[rugged shard]

hmm yeah i did the math and realized lmao

[near tartan]

If you want to look it up, this is a Supermicro H12SSL-NT

there's some really cool I/O on this

stuff you've probably never heard of

[rugged shard]

1000eur second hand 💀

[near tartan]

and of course an ipmi kvm bmc

[near tartan]

fake

[rugged shard]

probably

[near tartan]

i paid 650€ brand new

[rugged shard]

bruh

ebay scamming ppl now ig or smth

[near tartan]

brother is looking on google

im crine

[rugged shard]

lol

nah actually the first result was this

[near tartan]

okay wait stf

wtf

I'm lucky

[rugged shard]

what in the actual fuck

[near tartan]

that's fuckign crazy

[marsh holly]

You vill own nothing and ve happy

[near tartan]

ironically

yall know about LPCAMM2

[eternal wharf]

what about it

[near tartan]

i bought 32gigs when they announced the framework 13 pro for 250€

next day sold out everywhere, last know price over 800€

[storm bobcat]

how many cores those epycs?

[near tartan]

there are legit 0 offers for lpcamm memory here

[eternal wharf]

lmao

bro bought the last 2 lpcamm2 modules

[near tartan]

all three 24c/48t

the 7402s are dual socket

[storm bobcat]

ah so like 96t total?

[near tartan]

ye

[storm bobcat]

pretty cool

run zinnia on it

[near tartan]

i did

it works perfectly fine

[storm bobcat]

no NUMA?

https://tenor.com/view/no-bitches-gif-4978511433248186121

[rugged shard]

my server used to have 16gb of... ddr3

[near tartan]

that's just copium

real men suffer slowdowns instead

[eternal wharf]

just write your programs better

[near tartan]

fr

malloc_on_cpu(0, ...

[storm bobcat]

that kinda hardware sounds fun to do tests on

[near tartan]

it is

i can load isos from the web ui

it emulates a thumb drive

[storm bobcat]

if i had server grade stuff like that I could properly benchmark concurrency stuff

[near tartan]

you can get x99 boards for really cheap

like sub 100usd

lga2011

[storm bobcat]

yeah I know

https://gist.github.com/rdmsr/9188066462ab7039b60c09b10c25a75b

run this on it

but change the code to use like 96 threads instead of 12

[storm bobcat]

problem with that xeon stuff is that it's 1. old and 2. power hungry

[near tartan]

oh yeah

my epycs are low power asf

they idle around 60W

[storm bobcat]

cool

[near tartan]

which is what they're designed for ig

threadrippers are very similar, but just don't idle as well

[storm bobcat]

threadrippers are so cool

wish i had one 😔

[near tartan]

you can get first gen ones really cheap

or second gen even

i see cpu+mobo combos for about 300€

the biggest problem you'll have is that they only take rdimms

[storm bobcat]

at that point get a ryzen 9 tho

no?

[near tartan]

wdym

[storm bobcat]

some ryzen 9s have 16 cores

the point of getting a server CPU is more cores

but ryzen 9 is a consumer CPU and has 16 cores

[near tartan]

and IO

[storm bobcat]

yeah sure

but moar cores = moar better

[near tartan]

eh

the 7443 with its 48 threads is just as fast as a 9950x in coremark

[storm bobcat]

the only reason id get server hardware is for cores

idrc about IO

[near tartan]

128 lanes are cool tho

you can plug in a lot of shit

[storm bobcat]

GPU cluster

[near tartan]

like a 40g nic, multiple gpus at full speed, nvme bifurcation cards, etc

[storm bobcat]

56 cores holy

[near tartan]

there's better ones

there's ones with 192 threads

[storm bobcat]

need

can u do -j96 on zinnia or not

[near tartan]

you mean on smp boot?

[storm bobcat]

yeah

[near tartan]

i can boot all 95 APs

i can also disable xapic mode

it's kinda funny

managarm couldn't cope with it until i fixed it

[storm bobcat]

no but like

zinnia can run make right

[near tartan]

yeah

[storm bobcat]

could you compile something with -j96 without it being dogshit slow

[near tartan]

I'd have to try

I'm going to finish usb mass storage today maybe, then i can easily create and test stuff on real hw

I'll let you know

[storm bobcat]

implement xhci in zag

[near tartan]

but even on -j1 my kernel runs gcc quite fast

[storm bobcat]

yea but my point is parallelization not speed

it might be slower at -j96 than like -j4

[near tartan]

i could imagine that my tlb shootdowns are that bad

i have never tested

i only know it runs well on -j20

on my pc

[storm bobcat]

well that's good

ig a way to measure scalability is how performance scales (who would've thought?)

[near tartan]

i should follow that paper you linked

sounds fun

[storm bobcat]

no

it sucks

or rather

my thing is better

[near tartan]

i have yet to benchmark anything, most of the time I'm glad if it runs at all

[near tartan]

i didn't want to say "I'll steal your ideas"

[storm bobcat]

managarm also does async shootdowns

you might want to steal their design too

#1485107693458030706 message

[near tartan]

uh

[storm bobcat]

that's how it works

[near tartan]

how do i say this

i already do

then my shootdowns are also async

minus asids

i guess not really then

i hacked together an impl that works quite well

but i don't understand why it works

look at the blue cable

[storm bobcat]

https://github.com/zinnia-os/zinnia/blob/main/kernel/src/memory/virt/shootdown.rs#L408

that's synchronous

[near tartan]

then nvm

[storm bobcat]

your design could still be made asynchronous though

[near tartan]

i think i didn't do it because of that munmap thing

[storm bobcat]

it's basically asynchronous but you bolted synchrony on it

[near tartan]

but if i don't need to care if shouldn't be ab Problem

[storm bobcat]

my design is roughly similar to that

IPIs are not strictly needed, you just have to do it periodically (I do it on every quiescent state)

[storm bobcat]

idk if it's better, I'd have to think about it

[near tartan]

it probably is better, because mine isn't very well thought out

[storm bobcat]

well yours is from managarm

and managarm's is from korona

and korona has a phd

vs 18 yo with no degree 💀

[near tartan]

phd code mutilated by an idiot

[near tartan]

fwiw i also don't have a degree

i am a state certified SWE tho

[storm bobcat]

here you cant be an engineer without a degree

or rather

you can't hold the title

[near tartan]

my title is "Fachinformatiker Anwendungsentwicklung"

[storm bobcat]

you could've mashed your keyboard and I wouldn't have known

[near tartan]

put it in google or let explain it

it's a Germany only thing

[marsh holly]

How have you done usb so quicktly bruh

☠️

[near tartan]

by stealing from astral bruh

i told you

[marsh holly]

Yeah but I wpuldve expected tvat to take longer

[near tartan]

i have been working on it for 2-3 weeks i think

i started before czapek started playing cs2 24/7

[marsh holly]

Yeah bro just vanished from the vcs

[near tartan]

he was in a few days ago

me implementing yet another linux api just to get kde to compile

[marsh holly]

BSD larp (uBuntu Software Distribution)

[near tartan]

fr

well, i just implemented net/bpf.h

that's about as bsd as it gets

whenever I'm working on my mlibc abi i see AF_BLUETOOTH and it makes me wonder what the bluetooth stack looks like

[marsh holly]

Why do you need that for kde bruh

[near tartan]

dhcpcd

[marsh holly]

What linux api are you implementing fir kde

[near tartan]

some kankerfd i forgor what it's called

I'm basically going through dennis' kde prs

and translating to jinx

[marsh holly]

💀

[near tartan]

what

do you want me to CBT myself by doing it from scratch

[storm bobcat]

i think the managarm one might be better for a general-purpose thing

[marsh holly]

Yes

[near tartan]

https://tenor.com/view/cbt-capybara-capivara-chill-relax-gif-21621485

[shy turret]

yes

[near tartan]

well

i proably won't port sddm tho

as i already have lightdm

[marsh holly]

port xdm

[near tartan]

the x stands for good

[shy turret]

https://tenor.com/view/family-guy-joe-joe-taken-away-gif-17520860855595872089

port SDDM

[near tartan]

naw

that will require me to do even more linux VT/elogind kanker

[marsh holly]

U already implement a bunch of linux stuff might as well do it

[near tartan]

[shy turret]

do i hear? chicken?

[rugged shard]

While at it make the default theme be the one my school computers have from the gov distro

Fuck you Android

[nocturne rampart]

to compile android /s

[near tartan]

lol

[cerulean stream]

Bro give me some RAM 😭

[near tartan]

NO

😈

[shy turret]

Don't give me the ram, il end up eating it.
Plus I have uh 32 + 16 + 16 + 16 + 16 + 8 + 8 + 2 gigabytes of anyways in my hands anyways

[cerulean stream]

I have 16 GB of laptop DDR4 memory on an adapter from AliExpress

[near tartan]

bruh

[shy turret]

In this economy?

[cerulean stream]

I used to have it on my laptop way before the RAM crisis, when I built my PC I couldn't afford to buy new RAM so I ended up taking it from my laptop

[fair lintel]

this guy

why is this an int if you only ever return 0 or -1

[near tartan]

good point

i forgor

anything else

[fair lintel]

I don't think I have much else to say

using frg::string and string_view would have been nice, but whatever

[near tartan]

i am too far rust pilled

i mean sure

[fair lintel]

I wouldn't bother rewriting it to that now tho

[near tartan]

okay

[fair lintel]

what we may want to do at some point is to provide "default" impls for this that you can switch to with some meson flag

[near tartan]

in what way?

[fair lintel]

which would be implemented in terms of e.g. netlink or BSD socket ioctls

so that you would just opt into one of those instead of having to roll this yourself

[near tartan]

yeah

[fair lintel]

getifaddrs is actually a good example of this, there's a good chance that most sysdeps use one of the two mechanisms anyway, otherwise they'd have to write it themselves

[near tartan]

should be fixed now

[marsh holly]

@near tartan if I cooked up a generenic pkill/ps/etc implementation and made it generic/use sysctl (so no /proc brain damage) would u use it

[near tartan]

yeah

[marsh holly]

cuz u can't use procps-ng cuz that needs /proc brain damage

bet

[near tartan]

uhhhhhh

(it doesn't work)

thank you to dennis for the recipes

oh bruhhh this is a DRM meme

nooooo

tfw

miscompilation

me when startplasma hard codes some systemd shit

fuck that

[coarse pumice]

Bro didnt know kde is systemd hardcoded under compile

[marsh holly]

want to port systemdslop
complains that it wants systemd

smh marvin

[modern hamlet]

How much is the power bill

And 5 whole great rigs

What the hell man

[modern hamlet]

systemd's nuts

[median forge]

dbus is not only systemd

[near tartan]

what

no like, startplasma.cpp has some systemd code in there

[median forge]

a

then

F

[marble salmon]

didn't we do this already for getifaddrs?

[near tartan]

no

this was a draft pr by me

but it wasn't merged

i think?

or are you talking about something else

[fair lintel]

I'm not sure if we merged that, and I only remember doing netlink anyway

[near tartan]

that's in the linux sysdep

iirc the getifaddrs sysdep is gated behind linux

and my patch moved it out but there were some comments left to address

[fair lintel]

ah no, we discussed that as part of https://github.com/managarm/mlibc/pull/1705

[near tartan]

not that bad tbh

they idle very low

[near tartan]

the consequences of having a job and living with your parents

[modern hamlet]

you could be saving up for a car or some shit

in fact i bet you could buy a second hand car with the price of two of those

[near tartan]

i already have a car

[modern hamlet]

makes sense

[near tartan]

used too

[modern hamlet]

that extra thousand euros per month (or more) really coming in handy, huh

[fair lintel]

I updated that PR, pls take a look

[near tartan]

👀

[fair lintel]

it's really not that bad

[near tartan]

well it doesn't seem to compile

if the linux option is disabled probably

[fair lintel]

huh

oh that's fucking annoying

[near tartan]

i need to fix my risc-v port

[rugged shard]

everyone be getting kde running now huh

[near tartan]

mlibc users stay winning

[fair lintel]

the cycle of osdev discord:
step 1: ideas are born, memes are made of Dennis suffering
step 2: managarm get shit working on mlibc
step 3: wait 5-10 business days
step 4: multiple hobby OSes now have it

[silver birch]

what is left for mlibc at this point

[near tartan]

gnome

[silver birch]

you have systemd, chromium, kde

[near tartan]

and upstream

[marsh holly]

at least I got 2 firsts

wine and minecraft

[near tartan]

[fair lintel]

managarm had some of wine working before astral tho

[near tartan]

kde isn't that bad to port if you pretend to be a bsd or linux tbh

[fair lintel]

(it was quite limited tho)

[marsh holly]

the wine managarm has is completely lobotomized

it doesn't even enable mingw

[silver birch]

if you get gta 3 and gta san andreas running in wine with hardware acceleration using the nvidia module

im instantly uninstalling linux

[storm bobcat]

firefox?

[silver birch]

firefox too?

[storm bobcat]

idk I dont think they have firefox yet

[near tartan]

yes we do

[storm bobcat]

I was answering "what's missing?"

[silver birch]

no

[silver birch]

that's a list of things

running

ah wait nvm

[near tartan]

[silver birch]

welp

[marsh holly]

thanks to

[storm bobcat]

ok so what is left then

[near tartan]

gnome

and upstreaming everything for linux

[silver birch]

year is 2032

[sick flax]

and unclankering firefox

[silver birch]

mlibc has taken over glibc

[sick flax]

but time

[silver birch]

uacpi has taken over acpica

[sick flax]

YEAR OF THE MLIBC

[storm bobcat]

has rust been ported yet?

[near tartan]

yes

[storm bobcat]

zig?

[near tartan]

no

but it's not upstream

[fair lintel]

nobody bothered with zig yet, lol
