# Linux Kernel Module Cheat

Run one command, get into QEMU Buildroot BusyBox with several minimal Linux kernel module examples. Tested in Ubuntu 14.04.

Usage:

    ./run

First build will take a while (GCC, Linux kernel).

QEMU opens up, and you can run:

    root
    insmod /hello.ko
    insmod /hello2.ko
    rmmod hello
    rmmod hello2

Each module comes from a C file under `kernel_module/package/kernel_module/src/`.

The Linux kernel version can be found with:

    grep BR2_LINUX_KERNEL_VERSION buildroot/.config
