Bananymous	0cb53efa01	Kernel: 64 bit MMU now properly identity maps kernel	2023-05-05 14:19:28 +03:00
Bananymous	f139fc2229	Kernel: namespace and function renames ... MMU moved to namespace kernel Kernel::Memory::Heap moved to just Kernel MMU::map_{page,range} renamed to identity_map_{page,range} Add MMU::get_page_flags	2023-04-28 14:48:38 +03:00
Bananymous	3aa0eeb4a3	Kernel: Add barebones per process virtual addresses ... We now assign every (userspace) process its own MMU which we load in scheduler. This allows every process to have separate virtual address space. This is very hackish implementations but it works for now	2023-04-20 00:45:41 +03:00
Bananymous	b3eeb6412f	Kernel: Add some bareboness functionality to map virtual addresses	2023-04-19 23:51:36 +03:00
Bananymous	d38470c8e2	Kernel: Rename MMU::{un,}allocate... to MMU::{un,}map ... This is more appropriate name for the behaviour :D	2023-04-19 21:50:30 +03:00
Bananymous	2de64b592d	Kernel: Kmalloc now has its memory statically allocated ... We don't use the memory map given by bootloader since this automatically maps the memory to a available space.	2023-04-18 10:18:15 +03:00
Bananymous	9c0f3dd996	Kernel: Move kmalloc and MMU to Memory directory	2023-04-18 10:18:15 +03:00
Bananymous	06db890d49	Kernel: Add ubsan ... My brain has been melting since I'm getting very random bugs. I hope I can debug them better with ubsan :)	2023-03-06 23:38:05 +02:00
Bananymous	9756de02ef	Kernel: MMU now takes flags when allocating pages	2023-03-01 21:21:56 +02:00
Bananymous	9b8de5025a	All: rename every function from UpperCamelCase to snake_case ... This was a mess since I didn't know which to use but now I decided to go with snake_case :)	2023-02-01 21:05:44 +02:00
Bananymous	1687028ed5	Kernel: Add constructor and destructor to MMU	2023-01-30 18:54:04 +02:00
Bananymous	35d2e27292	Kernel: Improve MMU ... We don't have to invalidate page in AllocatePage() if we don't make any changes. We also should not assert on deallocating non-present pages, just return early :)	2023-01-26 02:57:14 +02:00
Bananymous	b315fdc27f	Kernel: Finally managed to get 64-bit working ... I had weird problems with interrupts but everything should work now	2023-01-25 19:19:28 +02:00
