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

Kernel: Fix 32 bit MMU
2023-04-22 18:22:39 +03:00
b1c7af38d0
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

0030f035be
Kernel: Rename MMU::{un,}allocate... to MMU::{un,}map
...
This is more appropriate name for the behaviour :D

6a3b3213cf
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.

fdb4eb6042
Kernel: Move kmalloc and MMU to Memory directory
2023-04-18 10:18:15 +03:00

Kernel: Add ubsan
...
My brain has been melting since I'm getting very random bugs.
I hope I can debug them better with ubsan :)

Kernel: fix i386 MMU
2023-03-02 00:47:29 +02:00

Kernel: MMU now takes flags when allocating pages
2023-03-01 21:21:56 +02:00

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
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 :)

c0bc002ac6
Kernel: Move debug printing to its own file
...
It didn't make sense that dprint was defined in Serial.h.
We also now dump dprint to tty if there is no serial and tty is initialized

Kernel: MMU rename weird variable
2023-01-22 20:16:44 +02:00
cdd27ae3db
Kernel: rename MMU::m_page_directory_pointer_table -> m_highest_paging_stuct
...
This might not always be pdpt. In x86_64 it is pml4/pml5
2023-01-22 03:03:58 +02:00
32453daf66
Kernel: actually dont map page 0
2023-01-13 15:04:06 +02:00

Kernel: remove debug print from MMU
2023-01-13 00:04:50 +02:00

Kernel: Add debug print to MMU and fix comment
2023-01-12 13:46:02 +02:00
301ad89783
Kernel: Unallocate RSDT after we are done with it
2023-01-12 13:45:01 +02:00
