- Updated gdt assembly
- Updated Interrupt service request handlers
- Improved virtual memory manager
- NOTE: we're dependent on identity mappings for the heap to work
Folders now are alll lower case
Started working on the implementation of the Virtual memory manager. Implemented allocate and free page funtionality for as far as I can atm.
Implemented the
Keyboard.h: remove the incorrect use of typedef
PhysicalMemoryManager.cpp:
Map the Bios region as used. This prevents us from allocation the area used by the bios
The first stage after GRUB will be Pre-Kernel. This stage will organize the
information we receive from the bootloader. (in our case that will be grub)
The second stage is for now called early_main. The program will at this
point already be running in virtual higher-half / higher-quarter address space.
The goal of the second stage is to set up the kernel in such a way that we are
ready to jump in to usermode.
The third stage is for now called kernel_main. This stage will jump us into
usermode and load the startup programs.
- Added a GRUB entry for tests
- Started writing the pre-kernel stage
- Removed knowledge of multiboot from early_main
- Edited the linkerscript to link variables in pre-kernel to
lower address space. ( from 1MB and up)
