CS 332: Operating Systems

Adding a "hello, world" system call to Linux

Due on paper 11:10 AM Wednesday, 5/19.

For this assignment, you will be adding a simple system call to Linux. What the system call does is immaterial--a simple print statement will be fine. The goal is to get you started looking working with the Linux source code, and to give you experience recompiling the kernel.

I strongly recommend that you work with somebody else on this project. There's lots of detail, and it will help to have somebody there for extra brain space and moral support.

Here's what you should do:

• Follow these instructions for adding a system call to add a simple "hello, world" system call to Linux.
• Keep notes on your experience, including stuff you had trouble getting to work, and questions you had but couldn't answer.
• Make your notes readable and hand them in.
• Come to class Wednesday prepared to discuss the experience.
