This post shows how to implement paging support in our kernel. It first explores different techniques to make the physical page table frames accessible to the kernel and discusses their drawbacks. It then implements an address translation function and a function to create a new mapping.

## Another Paging Post?
If you follow this blog, you have probably seen the [_Advanced Paging_](/advanced-paging) post that we published at the end of January. After receiving some [negative feedback] about the use of recursive page tables in that post, I decided to rewrite that post using a [different approach] for accessing the page table frames.
