  1. Course Overview Ted Baker  Andy Wang COP 5641 / CIS 4930

  2. Instructors Ted Baker Office: LOV 207A Office hours: after class and by appointment Andy Wang Office: LOV 264 Office hours: after class and by appointment Class website: www.cs.fsu.edu/~baker/devices

  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, 3rd Edition ISBN: 0-596-00590-3 Online version (free) 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

  17. Class Grading 91% - 100% A 89% - 90% A- 85% - 88% B+ 81% - 84% B 79% - 80% B- 75% - 78% C+ 71% - 74% C 69% - 70% C- 64% - 68% D+ 61% - 63% D 59% - 60% D- 0% - 58% F

  18. Computer Accounts, etc. ACNS account (@garnet.fsu.edu) Grade posting will be via Blackboard Card activation for 016 Love lab Fill out survey form and turn it in to Dr. Wang Need your FSU card number The door PIN that you want

  19. Course Policies Attendance mandatory Honor code: read your student handbook Students with disabilities Report to Student Disability Resource Center Bring me a letter within the first week of class

  20. Things for you to do • Fill out survey form and turn it in to Dr. Wang • Read chapters 1 and 2 of the text • Do lab assignment 1
