What is philix?
philix is a Linux command-line tool for booting third-party operating systems on the Intel Xeon Phi accelerator. It includes a basic virtual console and very minimal driver code for the Xeon Phi that you can quickly integrate into your own kernel to get started with a Xeon Phi prototype.
Why Do I Want It?
While you can certainly boot your OS on the Xeon Phi using Intel's MPSS software stack (and sysfs), you're not going to get any useful output unless you're willing to implement Intel's SCIF protocol in your kernel. This is a non-trivial task that is not worth the development effort if you're just trying to get some quick output from your kernel.
Take a look at some of the features in philix here.
