Basic block allocation for physical memory allocation. - 1 block = 4096 bytes : because this will make page fault handling possibly somewhat easier - 1 byte in the bitmap = 8 blocks of physical memory unsure if the allocation is perfect ... guess i'll find out some day if this is actually correct. The bitmap needs 16kb to keep track of 2gb of physical memory. Seems a decent percentage to me. 2022-02-26 19:44:16 +00:00			`extern "C"`

More work on interrupt handling, Started timer interrupt implementation, PIC remapped hopefully successfull 2021-05-16 14:53:14 +00:00
Adding a skeleton for the memory management code Moved the PMM away from being object orientated as it is just plain annoying renamed src folder to source Set timeout to 5 seconds in the grub config 2022-08-21 19:18:53 +00:00			`#include "Memory/PhysicalMemoryManager.h"`

Clean up of debugging logs and new commands. As this project grows it becomes important to keep things properly organised. In this commit I've put some effort into making the kernel.cpp file more consise and thus improve its readability. Certain parts of the code have gotten their own definition file where before it was only a header file. - Moving the Supervisor Terminal into its own definition file. - Subtracting debugging messages with preprocessor ifdef's - Time and Date is now not just a header but has its own proper definition file - Banner is displayed when booting up - Terminal has a couple new commands Commmand Description =================\|\|\|\|\|=================================================== DATE (was TIME) Displays the curren time, date and ticks VERSION Displays system version information MEMORY Displays memory information 2021-12-29 15:15:18 +00:00			`#include "time.h"`

Divided the kernel into seperate distinct phases 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.

Page faults and protetion faults will now hang with a helpful message to explain what is going on. I removed previously set barriers from the code to load the kernel further. 2022-08-18 22:44:52 +00:00			`#define CHECK_FLAG(flag, bit) ( flag & (1 << bit ))`
