Code Examples

Simple proc module that spawns a kthread on load (put this in a seperate directory). You might want to use this module as a base for your full kitchen module.

• kitchen.c
• Makefile - compiles a kitchen.ko module

Sample bash scripts to control your kitchen module. May need to run chmod a+x <script.sh>. Must run in same directory as file kitchen.ko.

• load_kitchen.sh - wrapper for insmod
• start_kitchen.sh - sends a "0" to file /proc/kitchen
• stop_kitchen.sh - sends a "-1" to file /proc/kitchen
• unload_kitchen.sh - wrapper for rmmod
• watch_kitchen.sh - load in a different window to constantly read status
• watch_syslog.sh - load in a different window to constantly watch output of printk

Binary kitcen module so you can see how my implementation works. Just copy this file into your virutal machine and load with insmod or ./load_kitchen.sh (above script).

• If you are running the original (64-bit) virtual machine, run this module in your 4.4 kernel kitchen.ko
• If you are running the alternate (32-bit) virtual machine, run this module in your 4.4 kernel kitchen.ko

Fine print: binary kitchen distributed "as is". NO guarantee for successful run of real restaurant or cooking of real food. Please report any bugs found.
