68371475d9 Marking memory management features as done. Work still needs to be done but the bare minimum for memory management is there. 2022-09-03 17:38:22 +02:00
2e59e6593e Add proper Physical memory management to this branch
to ensure it doesn't get too out of date

We can now run the FAT command to demo reading out the FAT16 filesystem,
however this will cause the need for a reboot as after this command. We are FOR NOW
not able to put in any new commands

b4cff3e667 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.
