## Conclusion
Now we have a working frame allocator. It is a bit rudimentary and cannot free frames, but it also is very fast since it reuses the Multiboot memory map and does not need any costly initialization. A future post will build upon this allocator and add a stack-like data structure for freed frames.
## What's next? ## What's next?
The next post will be about paging again. We will use the frame allocator to create a safe module that allows us to switch page tables and map pages. Then we will use this module and the information from the Elf-sections tag to remap the kernel correctly. The next post will be about paging again.
