11/1/16: Finishing up Kernel programming & virtual memory

• We'll begin with exercises today!
  • First, answer this short survey designed to check your understanding of kernel programming and virtual memory
  • Next, if you have not finished the exercise from last Thursday, you may do so now.
  • If you have finished the exercise, then here is a fun way to bring together multiple things we've learned in the course -- build kmalloc -- the kernel's malloc.

• Lecture notes

• Answers to survey questions

• Reading
  • The Evolution of the UNIX time-sharing system This is a lovely paper that explains some of the how and why behind the way we interact with operating systems today.

• Supplementary materials (Mix videos from 2015)
  • VM Tricks
  • Kernel programming
  • Fork and Exec (We'll talk about fork today; exec later.)
