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.
The following screenshot summarizes its functionality:
MSRV
The MSRV is 1.70.0 stable.
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, things are a little clearer to me now.
