Hello,
I am currently improving my paging code. I was curious as to how I should access the tables themselves, since the cpu can only use physical address for these tables. I have been accessing them via physical addresses, as the first 4MB are identity mapped. Thank you for your help.

Map the pages you want to access in your page table. Then you can access them using virtual addresses.

You might want to look into recursive paging.

This article: https://os.phil-opp.com/paging-implementation/ discusses the problem, and various solutions. I favour the "Map the Complete Physical Memory" approach.

Thank you for your help. I have decided to use recursive paging and it works quite well for me.
