Meow :3

started as a joke because I wanted to get back to osdev but it's my 4th kernel and the best one at the moment, I thought "what if I keep a nice file and code structure" so there It is, I'm actually studying every wiki article instead of copying and pasting code and it gives me satisfaction. Early stage tho.
I don't even have a term emulator (who needs it when I have serial)
There's libm (lib meow) instead of libc (it's just libc).
I have "@details: " for most of the functions.
I have a RNG that uses rdtsc as seed
logger, paging (took 2 days), gdt, serial and I'm doing idt rn.

[shut drift]

cool

[hidden salmon]

it is the standard "x86_64 + monolithic + limine" kernel tho so nothing too special

[radiant arrow]

why x86_64? i require aarch64

[hidden salmon]

I mean the file arch/arch.h is:

#ifdef __x86_64
#include <arch/x86_64/arch/arch.h>
#endif

so feel free to add your aarch64 implementation

you reminded me that I have to put a different init for each cpu arch

[radiant arrow]

idt

[hidden salmon]

I want to make an init system btw :3

How complex of one

[hidden salmon]

I never wrote an init system so idk

[clear turtle]

My os's one is pretty simple, it just sets up the starting env variables, runs /etc/rc which mounts things such as /dev and then either runs x and fvwm or just drops to a shell in the system console

Itd be interesting to see someone do something more complex

[hidden salmon]

I was thinking to read sinit source and make it simpler

maybe .service files

or something easier than .service

just:

exec = /bin/xx
description = "Service 00"

once you have a RW filesystem everything is possible

very clean looking kernel

[hidden salmon]

idt, initrd, working on apic

meow now supports new cpu architectures (i386 and aarch64). What I mean with "support" is that now you can build the kernel by using the env variable ARCH that can be x86_64 | aarch64 | i386 but the i386 version and the aarch64 are very basic and support just kernel boot, so feel free contribute to the project

[hidden salmon]

I'm having some problems with interrupts (I nono wanna) so I might take a little break or focus on more of the kernel

[hidden salmon]

oh and new PMM + Heap management, now it's cool and I can free allocations

• the PMM it's now using the entire memory instead of a specified number of bytes
