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.

Prioritise output before all else, just so we know when the kernel actually works.
2019-08-19 22:55:28 +01:00
24aad1e4a5
Fix a silly issue with the Interrupts using bits instead of bytes when reading and writing ports.

Gitignore weirdness.

Update README for new build.
...
NOTE: for every new successful build, start incrementing the SYNC_VERSION constants in kernel.h :D
2019-07-24 21:53:01 +01:00
f9dcdf5cc9
Update compiler script.
...
It all works now.

Now that all the files we need are available..
...
Added the c_files.txt file required by the sneklang compiler script.
2019-07-24 20:25:21 +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
78dcb1a707
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.
:)
2019-07-24 19:47:44 +01:00

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.
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
633f6b925e
Add bitmap font.

Half home-brand, adapted from font8x8 from the public domain.

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.

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

Fix some oversights in the header.
2019-07-23 19:27:47 +01:00

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

Additionally, added header comments to all files.
