KERNEL: Cleanup Removing quite a few unnecessary parts. 2022-09-01 15:02:04 +00:00			`#include <stdint.h>`
Added checks to be sure paging is actually enabled on the cpu. - Made a special assembly file to put CPU check function in. E.G. functions to get the state of specific registers In this case I have created a simple assembly function to get the contents of the CR0 register. With the help of the c++ preprocessor the value can then be used to check if certains bits are set. For example to check if the PG (paging) bit is set, indicating that paging is enabled for the processor. 2022-08-16 17:06:16 +00:00
KERNEL: Implementing VMM & cleaning up 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 2022-09-01 18:16:16 +00:00			`uint32_t GetEFLAGS();`

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
