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

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

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

Prerequisites COP 4610  Undergraduate Operating Systems or, COP 5570  Advanced Unix Programming or, Proficiency in UNIX environment and C

Course Material Lecture notes (posted at the class website) Textbook  Writing Linux Device Drivers  ISBN:

Course Material Recommended textbook  Linux Device Drivers, 3 rd Edition  ISBN: Online version 

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

Class Participation Two absences are allowed without question or justification Grade will be reduce by 1% for each missed class Exceptions:  Documented religious holidays and emergency  Cases pre-approved by the instructor

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

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

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

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

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

Quizzes Several short quizzes  On average, one quiz per week  Not necessarily announced in advance (Dates on calendar are just illustrative.) No make-ups for missed quizzes  For excused absences or lateness The missing quizzes will be dropped
