Add EFI headers.

Add all of the functionality to allow the kernel to boot itself.
...
This is a trimmed down version of Syncboot integrated into the kernel.
The plan is, eventually, to allow the kernel to be booted by Syncboot, but that'll take a lot of research into QEMU.
This was just quicker to do.
This isn't tested, as I still need to figure out how to compile the EFI entry point separately.
They can be linked together, however. That's why the kernel is designed around a PE32+ format.

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

6238fbf8fe
Added serial functions to the kernel header, making them global.
...
Also moved the definition of IRQ_Functions out of the header, as this is changed.

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

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

Prioritise output before all else, just so we know when the kernel actually works.

Fix a silly issue with the Interrupts using bits instead of bytes when reading and writing ports.

NOTE: for every new successful build, start incrementing the SYNC_VERSION constants in kernel.h :D

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

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.

Remove inb and outb, since they have counterparts in ReadPort and WritePort.
