Paging Address Calculator

paging-calculator is a CLI utility written in Rust that helps you find the indices that a virtual address will have on different architectures or paging implementations.

It takes a (virtual) address in hexadecimal format and shows you which index will be used for what page-table level. It can be installed with $ cargo install paging-calculator.

Valid inputs are:

• $ paging-calculator 0x1337
• $ paging-calculator 0xdead_beef (underscores are accepted)
• $ paging-calculator 0xdead_beef x86 --pae (underscores are accepted)
• $ paging-calculator 0xdead_beef x86_64

Type $ paging-calculator help to get a list of all supported options.

Trivia

I worked on a project where I need to set up page-tables on my own. I had a few problems to find out what I actually have to do and what indices are used at which level. With the help of this utility, this task becomes quite easy.
