Kine: Kine Is Not an Emulator

K is a toy kernel used as a kernel project at EPITA (Sources). This kernel can run userland programs/videogames called roms. Those roms are statically linked i386 ELFs, but K has its own syscall interface, and its own memory layout, both not compatible with Linux. In order to be able to run those roms in Linux, one solution is to use a custom loader (like wine, but way simpler). This project is this loader.

Usage

$ git submodule update --recursive --init
$ make -C ./third_party/k/
$ ROOT_PATH="./third_party/k/iso"
$ ROM_PATH="./third_party/k/roms/skate/skate" # Or any other rom
$ make
$ ./kine -p "$ROOT_PATH" "$ROM_PATH"

Motivation

I wanted to play with the new prctl PR_SET_SYSCALL_USER_DISPATCH, so I wrote an emulation layer for github.com/lse/k. It also seemed like a good opportunity to throw some assembly and few calls to modify_ldt(2) :).
