Now that all the files we need are available..
...
Added the c_files.txt file required by the sneklang compiler script.

Add some public-domain memory manipulation files as a stand-in for my AVX functions.
...
These are messy, but they let the kernel compile.
2019-07-24 20:24:38 +01:00

New compiler script!
...
Now with 100% more sneklang!

It's interrupt time, baby.
...
This should bring the kernel to a working state.
Don't forget that the interrupts.c file absolutely must be compiled with -mgeneral-regs-only.
All the other files absolutely must be compiled with -mavx2.
:)

Slight kernel.h cleanup.
2019-07-24 15:54:32 +01:00
f74809718a
Slight cleanup of utils.c
...
Also added the missing memX functions needed for compilation.
Interrupts next, I do believe.

e4500c27e3
Finish basic memory management.
...
This won't compile, as it's missing the xAVX functions.
I have a sort-of implementation of them, but it's brutal.
5400 lines total.
For now, they can be substituted with the x functions (remove AVX) to compile the kernel.

The print file.
...
A whopper. Lots of printing functions, most of them internal.
No this doesn't mean actual physical printing, it's printf, etc.
2019-07-24 01:39:00 +01:00

Add the bootstrap file.
...
Provides all the functions necessary to get the kernel started, and to continue working in the future.
It is to be split up in the future.
