Added a ClearScreen call to the graphics init.
...
This should erase everything on the screen before anything else.

Enable all serial debugging outputs in the interrupt handlers.
...
Serial should be working now, but i can never trust things to work first time.

Removed beep on boot.

That stuff hurts, man.
Also moved all the ASM port wrappers into their own file.

Seriously prioritise output.
...
Added a beep function to allow PC Speaker output.
This will require an edit to the current QEMU launchscript to get working.
2019-08-19 22:58:26 +01:00
437e10e86c
Prioritise output before all else, just so we know when the kernel actually works.
2019-08-19 22:55:28 +01:00

Fix a silly issue with the Interrupts using bits instead of bytes when reading and writing ports.
2019-08-19 22:54:08 +01:00

Add missing Reserved ISR Handler function.

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.
2019-07-24 20:24:38 +01:00
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.
:)
2019-07-24 19:47:44 +01:00
f74809718a
Slight cleanup of utils.c
...
Also added the missing memX functions needed for compilation.
Interrupts next, I do believe.
2019-07-24 15:54:14 +01:00
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.
2019-07-24 15:53:39 +01:00
f88524a9b9
Starting memory management.
2019-07-24 01:39:12 +01:00

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
cdd8b7933f
Remove inb and outb, since they have counterparts in ReadPort and WritePort.
2019-07-24 01:38:00 +01:00

More minor changes.
...
Header and graphics had some one-liners.

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

Add Graphics file.

A few TODOs here, but nothing that can't be handled.

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.

Change branding, ProjectRED -> Sync.
...
Additionally, added header comments to all files.
The next few commits will likely be structure and comment-related.
2019-07-17 02:04:04 +01:00
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.
