q3k 949180a993 Re-enabled C++ support, it seems to be working. 2013-02-03 15:53:33 +01:00
q3k 0f0380a0e3 Bigger initial heap, remove debug from kmain(). 2013-02-03 15:52:18 +01:00
q3k ffff4729ae Heap fixed. w00t. 2013-02-03 15:42:40 +01:00
q3k 87907c0f75 Paging now works, heap still borked. 2013-02-03 14:38:48 +01:00
q3k c93a20ad03 Replaced the crappy miniVMM with a kernel scratch thing. 
it starts at 0xFFFFFFFF00000000, it's mean, it's unmanaged, but you can make a heap on it later. But it broke everything, so I need to fix that.

One step closer to saner memoy management, I guess.

q3k b5ecbd1a07 Revamped the physical frame manager. 
It now uses bitmaps, but is limited to one of them, so 128M of RAM.
I'll have to fix this someday, but right now it failing gracefully and reminding me that my shit's broken should be enough.
 2012-10-30 15:37:51 +01:00
q3k 11e6c2a34d Basic idea about virtual memory... Now we need a physical memory 
manager beforehand.

q3k 0fbd91d599 APIC timer calibration. 
Kind of. With the PIT. So 90's.
 2012-10-29 18:59:09 +01:00
q3k 54a5e96722 More work on APIC. 2012-10-29 14:57:48 +01:00
q3k 05b3631004 LAPIC access via macros instead of structures. 
Because I couldn't discover a way to make gcc access these structures in a sane, 32-bit wide way.
 2012-10-29 11:08:58 +01:00

q3k 848d5ebb63 QEMU without kvm. 2012-10-23 21:20:03 +02:00
q3k 99912f2083 C++! 2012-10-01 15:03:10 +02:00
q3k cd811bda04 Lua is now running. 
The interpreter is working perfectly, albeit missing some
useful libraries.
 2012-09-24 15:17:26 +02:00
q3k 57601cac2c Fixed Lua interpreter crap. 
My memcmp() implementation was non standards compliant. Fuck.
 2012-09-24 14:33:04 +02:00
q3k 58682720e1 Implemented setjmp() and longjmp() 
And they worked on the first try...
 2012-09-24 14:22:38 +02:00
q3k 5ecc85f8ec More progress on Lua. 
It runs, but fails. Setting up setjmp() and longjmp() to do
actual debugging;
 2012-09-24 13:43:32 +02:00
q3k d8aab40557 glue code for lauxlib written 
I ended up writing all the file and stirng functions required
for making lauxlib compile.
 2012-09-21 12:45:46 +02:00
q3k 8d01b60ba2 Makefile modified to build Lua. 
But it isn't being used just yet...
 2012-08-23 16:11:41 +02:00
q3k 58a49b7ffb Including stubs for Lua to use. 
Because I forgot them.
 2012-08-23 15:44:36 +02:00
q3k 4161c5950b Lua now compiles. 
But it still won't link against the kernel, as it's missing
a lot of ANSI C functions. Time to find some BSD/MIT libc
implementations...
 2012-08-23 15:42:57 +02:00
q3k 94339f53f6 I'm a silly moose. 2012-08-23 14:04:48 +02:00
q3k 5c922d933e Lua support in the process of being added. 
Lua still doesn't compile, but I'm in the process of adding some
stubs (some really silly ones), in order to at least get it to
build properly.
 2012-08-23 13:58:23 +02:00
q3k b7f0c48873 Intermediate register for LIDT so that it compiles with the new memory model. 2012-07-21 00:41:03 +02:00
q3k b19b999489 GCC. Your debug segments. Out. Now. 2012-07-21 00:40:26 +02:00
