5ed922bd20 Update serial functions for new WritePort system. 2019-07-24 21:49:35 +01:00
5760ed1dde Add some public-domain memory manipulation files as a stand-in for my AVX functions.
These are messy, but they let the kernel compile.

f92114539c 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.

:)

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.

f88524a9b9 Starting memory management. 2019-07-24 01:39:12 +01:00
874e7e9a05 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.

cdd8b7933f Remove inb and outb, since they have counterparts in ReadPort and WritePort. 2019-07-24 01:38:00 +01:00
f524eee6ff More minor changes.
Header and graphics had some one-liners.
2019-07-24 01:37:39 +01:00
80154dbb51 Update main kernel file and Utils for the new functions.
Can't use term_x any more.
2019-07-23 23:01:12 +01:00
d14da0af89 Add Graphics file.
A few TODOs here, but nothing that can't be handled.
2019-07-23 22:59:33 +01:00
67cbaad539 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.
2019-07-23 20:32:24 +01:00
c9bd659f5c Add bootstrap source.
Made to manage holdover from Syncboot, but is half-finished because of
an issue with the prior mentioned header file.
2019-07-22 22:34:02 +01:00
04e70ab274 Commenting improvements
Even more preparing for UEFI.
2019-07-22 22:32:35 +01:00
93729c40b5 Change branding, ProjectRED -> Sync.
Additionally, added header comments to all files.
The next few commits will likely be structure and comment-related.

4edd4b7cc8 Major refactor. Major improvements.
All ISR/IRQ stuff moved into its own header and source.

Comments added on all major parts.

Some optimisations in important functions.

All ASM removed for ISR and IRQ, instead using new GCC directives.
2019-06-27 19:57:54 +01:00
022884e20d Fixes and improvements.
Including a new, rewritten and restructured boot.s file, plus automagical Protected Mode.

31d2e10b69 Implement a GDT, IDT with ISR and IRQ
Basically, added error handling, interrupts and basic hardware communication is now possible. Yay.

e4fcbb20b4 Implement Serial Console messaging.
Intended to be used for debugging, but it's useful.

Next up is a Serial Console
