3. Meeting Place and Times Monday – Friday: 12:30am – 1:45pm  LOV 301 (sometimes at LOV 016) In addition  You will spend lots of time on projects  Projects will need to be done in the lab, unless you have a PC that you:  Don't mind trashing, through kernel bugs  Can bring into the lab for demos  Have your own device

4. Course Objectives Make yourself into a Linux kernel “hacker”, who can:  Configure, compile, and install a Linux kernel  Do the same for a kernel module  Navigate and read the Linux kernel sources  Use the API for internal kernel services  Design and implement a kernel module  Modify, or design and implement a device driver  Measure the performance of your implementation

5. Applicability of Kernel Hacking Skills Software engineering Concurrent programming Thesis and dissertation Employment

6. Prerequisites COP 4610  Undergraduate Operating Systems or, COP 5570  Advanced Unix Programming or,  Proficiency in Unix environment and C, and  General knowledge of operating systems design principles

7. Course Material Lecture notes (posted at the class website) Required textbook  Writing Linux Device Drivers  ISBN: 978-1448672387

8. Course Material Recommended additional textbook  Linux Device Drivers, 3 rd Edition  ISBN: 0-596-00590-3 Online version (free)  http://www.lwn.net/Kernel/LDD3 http://www.lwn.net/Kernel/LDD3

9. Class Grading Assignment 1 (individual): 10% Assignment 2 (individual): 15% Assignment 3 (individual): 15% Assignment 4 (team + report): 30% Quizzes:30%

10. Class Participation Grade will be reduce by 1% for each missed class Exceptions:  Documented illness, deaths in the family and other documented crises, call to active military duty or jury duty, religious holy days, and official University activities  Other cases pre-approved by the instructor

11. Assignments Reading Programming  You will be provided access to a PC (LOV 16) It may need to be shared  First three assignments: lab. exercises  Last assignment: team projects Each member will evaluate the contribution of the other team members  Warning: they get more difficult, exponentially

12. Some Possible Team Projects Device drivers  Video cards  Cellular phone sensors  LED devices  Solid-state storage (e.g., flash) New kernel features/optimizations  Mechanisms to optimize flash deletes  Mechanisms to track and categorize storage I/Os  Mechanisms to perform secure deletion Your ideas?

13. BEWARE Assignments may be very time consuming  Non-deterministic bugs  Obscure bug symptoms Not much information about where an error occurred  Need frequent reboots and OS reinstallations Implications  Start your projects early  You are responsible for backing up your work

14. BEWARE If you plan to use your own computer  You will need to bring in your machine to demonstrate your code  You might trash your hard drives

15. Some Useful Tools Virtual machines  VMWare  Xen  Virtual PC User Mode Linux (UML) These take time to learn and install  Will not help when you get to a real device driver  No time to cover them in class  You will need to teach yourself

16. Quizzes Several short quizzes  On average, one quiz per week  Not necessarily announced in advance (Dates on calendar are just illustrative.) Missed quizzes  For excused absences or lateness Make-up arrangements must be made with instructor Usually, an oral examination
