f79f04361a
Added a ClearScreen call to the graphics init.
...
This should erase everything on the screen before anything else.
2019-08-20 16:42:57 +01:00
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.
2019-08-20 16:42:24 +01:00
d3c8dd45c7
Enable all serial debugging outputs in the interrupt handlers.
...
Serial should be working now, but i can never trust things to work first time.
2019-08-20 16:41:50 +01:00
4af4ad89a4
Updated the kernel.c comments.
...
Minor changes, but whatever.

Added the current timer tick as a global variable.
2019-08-19 22:58:45 +01:00
2691c1e30e
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
24aad1e4a5
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
bec10bcee8
Gitignore weirdness.
2019-07-25 00:44:34 +01:00
a5ce202055
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.
\o/
2019-07-24 21:50:26 +01:00
d2d532c535
Add missing file to c_files.txt
2019-07-24 21:50:01 +01:00

...
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!
2019-07-24 20:19:49 +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
debd7ef91a
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.
2019-07-24 01:39:53 +01:00
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.
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
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
15293681ea
Add AVX memory prototypes, rename ResetDefaultScreen features to something more sensible.
2019-07-23 23:00:13 +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
c795a936ae
Fix some oversights in the header.
2019-07-23 19:27:47 +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
2bfe904014
Add main kernel header.
...
Defines all of the structs, functions and variables for the new kernel.
Currently has some issues with GCC.
