FrostixOS

[bright ingot]

Soooo... My new project cuz i hate asm and i dont want continue FaslinkOS development.
Current features:

• Simple video drivers (vga text, vbe)
• Simple libraries for terminal and C
• cool font = )
• interrupts, gdt
• very cool makefile
• 2 stars on github
  github: https://github.com/Kross1de/frostixos

Two stars on GitHub? Nice OS feature 🙂

[jagged jay]

lmfao

[bright ingot]

this is most important

[sick adder]

Nice!

[bright ingot]

i integrated printf

from this https://github.com/mpaland/printf

[bright ingot]

more and more progress

[bright ingot]

fixed pmm and logger written and serial driver too

[latent niche]

Nice bro!!! Looking good

[bright ingot]

ty

last day of summer...

[latent niche]

Dang bro my school don’t start for another MONTH 💀

[bright ingot]

lucky

[karmic mango]

lucky mf

[bright ingot]

1 september

[latent niche]

Very sad ((

[bright ingot]

im home

[bright ingot]

fixed the serial printf bug and also

idk i do mirror messages like

check screenshot idk how to say it english

so i will work on vmm & paging

[bright ingot]

soo

my vbe driver is broken

and when i tested my os on real hardware

i just get a black screen

i think this will the biggest problem

[latent niche]

It shouldn’t be

Output isn’t that important

[bright ingot]

so idk

i will switch to limine

cuz im dumb

[bright ingot]

smth like this

now i need rewrite a makefiles and do a new file structure

[bright ingot]

I'll just rewrite vbe I don't like limine template

[bright ingot]

Sorry for not working on the system but I have little time now I hope to publish something soon

[bright ingot]

1 commit after 10 days

but so

my os working on real hardware now

and new vbe written

[bright ingot]

i get cpuid work

and also almost 4k lines

[bright ingot]

I just now remembered that I have screen.c

it need to be rewritten

[bright ingot]

ansi is working

[bright ingot]

this font is better?

i found the best

[bright ingot]

trying to printing time

but it's hard

[bright ingot]

tf with git

i cant push

[bright ingot]

guys i need testers for some reason it doesn't detect my flash drive and I don't know why so i cant test frostix and real hw

If you can pls respond

[karmic mango]

what doesn't detect your flash drive

are you using ventoy

[bright ingot]

i using balena etcher for writing to usb

no

[bright ingot]

back to work

[terse tinsel]

Rufus works too. if its MBR

[bright ingot]

rufus only for windows

[terse tinsel]

You on linux?

[bright ingot]

ye

[terse tinsel]

Is you OS MBR?

or EFI?

[bright ingot]

mbr i think

[terse tinsel]

Does ecther even support MBR?

[bright ingot]

yes

[terse tinsel]

You can try to do this manually too. like burning the ISO (if ISO) on to the flash drive like using the dd command

[bright ingot]

no i don't have an sdc in /dev either

well, I mean

when I insert a USB into my computer the sdc doesn't appear

so i cant use dd

YOOO WAIT

I GET IT WORKS

bruh

so some tests on real hw now

[terse tinsel]

does it boot?

[bright ingot]

wait

i will test now

[bright ingot]

yes it booting

:^)

[terse tinsel]

Noice

[bright ingot]

but i need optimize rtc time printing

it's very laggy

[terse tinsel]

Real hardware timings.

[bright ingot]

acpi is hard ((

[bright ingot]

o oh that's bad

[karmic mango]

you're doing ACPI mode?

[bright ingot]

yes

[bright ingot]

okay...

[bright ingot]

40 commits in 2 months...

bruh it's insane

[bright ingot]

ehhh

on qemu i finding rsdt with 4 tables

but on real pc i finding xsdt with 18 tables

[spring rivet]

this is normal

there isn't a set number of tables

you might want to look at uacpi

[bright ingot]

ehhh

ok

sheesh

why there codebase bigger than my whole os bruh

there's 1 file bigger than my whole os

[karmic mango]

AML is complex

[spring rivet]

same uacpi is about half the size of the entire rest of my os, and mine isn't trivial

but it's worth it

[boreal jewel]

it's not safe to enable ACPI mode if you dont handle general purpose events

[bright ingot]

i parsed madt

[bright ingot]

last day of vacation(

so i will have less time for development

[bright ingot]

works but ?broken?

[bright ingot]

guys what's better cpio or tar

[spring rivet]

for what problem?

[bright ingot]

I want to make an initrd in the future

[bright ingot]

implementing slab allocator rn

[latent niche]

niceeee

that was a fun thing to implement for me

if u need help you can ask me or refer to mine

i can also speak russisan so

[bright ingot]

cool

[bright ingot]

my flash drive is suck

and my scrolling too

on real hw i get 1 line per 10 seconds

it's very very slow

im dumb

[bright ingot]

400 lines in vbe🔥

[terse tinsel]

cool

[bright ingot]

guys i need new flash drive

mine broke

[bright ingot]

after 3 days i finished my very nice commit

[bright ingot]

file format not works nice lol

[bright ingot]

new kernel panic design🔥

also i simplified very much stuff and added comments and formatted my files

so my goal is vma

and improved mm

[bright ingot]

E820 memory map parsing, initrd placeholder

i took a little break

omaga

biggest commit in the history lol

[bright ingot]

lool

I didn't even expect that getting initrd would be so easy

[bright ingot]

new kernel panic design (again

[spring rivet]

how useful is the info, except cr3

[bright ingot]

idk

[spring rivet]

generally a stack trace is more useful

[bright ingot]

not tested

stack trace?

[spring rivet]

cr3 shows the faulting address

yes, stack trace, like a traceback

[bright ingot]

oh

окак

ok

[spring rivet]

like that

so you can see where it was and what functions were on its stack when it crashed

[bright ingot]

ty

[spring rivet]

yw

[latent niche]

How do you implement this

[spring rivet]

compile the code with stack frames and then walk the stack like a linked list

frame-pointers is what it's called iirc

src/debugger.c in retro rocket

[latent niche]

Ah okay

[latent niche]

I’ll go take a look

I’ve implemented one in Linux userspace but

I didn’t know if it was more involved for kernel space

[spring rivet]

you also need a symbol list to map address to name,.use nm -D | sort -n >symbols

that's the bit that stumps people because they assume they gotta have debug symbols and parse DWARF

[latent niche]

I already compile with debug symbols for addr2line

[bright ingot]

my VPN stopped working and now I only have 360 ​​minutes a day because the creators of uVPN and SandVPN are fucking idiots

[rocky knot]

symbol list where btw

[rocky knot]

Proton or Cloudflare vpns?

[spring rivet]

nm kernelbinary | sort -n > kernel.sym

then load the kernel.sym as a limine module

[rocky knot]

oh

that's cool

thx

[karmic mango]

or use the limine executable request and parse the elf symbols directly

[spring rivet]

yeah, I find having an external symbol file more useful

I compress mine

[karmic mango]

fair but i prefer not having extra files :p

[bright ingot]

no i used free uVPN but it's now broken and i using sandvpn now

but

if i using free version i have 360 minute per day

[bright ingot]

initrd done

using tar

[fast gull]

Damnn

Would be useful for me0

[spring rivet]

just realised you dont need the -D

-D is for dynamic syms, most kernels dont have them

[fast gull]

Is kernelbinary must be .elf or can be .iso?

[spring rivet]

elf only

nm extracts symbols

[rocky knot]

iso is a zip basically

that contains the elf

[spring rivet]

iso isn't a zip

it's a filesystem image

but I get what you're trying to convey

[rocky knot]

it can be converted to a zip

and explored the same

so it is some kind of zip

[spring rivet]

no it's not

a zip is compressed, an iso is not

its just files in a container

like tar

[fast gull]

Thanks

[wary aspen]

@bright ingot i always come back...

HE ADDED INITRD ????

wait no i have to see this shit.

this is to op

[hybrid phoenix]

oh god, stop pinging them so much

[wary aspen]

ok ? i am friend whit him its alr.

sorry tho

[bright ingot]

yea if you need to ping me do it 1 time NOT FUCKING 7 TIMES

[bright ingot]

idk why

but discord now working without vpn

Roskomnadzor decided to unblock Discord in Russia???

[tired crater]

No way

[sick adder]

Surprised.

[bright ingot]

i will comeback soon... maybe...

[bright ingot]

i think i can start work again

[bright ingot]

dumbass fucking bitch

he said like

if youtuber dont scam subscribers and he doing video for kids

he just a cringe

bro wtf

[bright ingot]

linux delete /boot /home and other directories nice

also i switch back to window

s

[fast gull]

You can safely delete /home I think..hmm, idk, maybe? Just use /root as your primary user?

[bright ingot]

i dont think

[spring rivet]

you can have home directories wherever you want

im pretty sure freebsd has them at /usr/home, or did

and the www-data linux user has its home at /var/www

[bright ingot]

that's good but
