Introduction to Operating Systems Project: Priority-based Scheduler for Xv6

1. Overview

In this assignment, you will learn how to implement a priority-based scheduler for xv6. To get started, download a new copy of the xv6 source code from here. Do NOT use the source code of project 1. You'll do two things in this assignment:

You'll replace xv6's current round-robin scheduler with a priority-based scheduler.
You'll add a new syscall for a process to set its own priority.

Words of wisdom: ?rst, please start early! Second, please make minimal changes to xv6; you do not want to make it hard for us to grade!

Deliverables

Submit in the blackboard your modified source code of xv6 as a gzip compressed tarball. Include in the tarball all ?les necessary for a successful build! The name of your attachment should be cop4610-proj4-your_fsuid.tar.gz with your names replaced by your CS account name. Your submission will be graded by compiling and running it and reviewing the source code.

As usual, the grading platform is linprog. Make sure your code works on linprog.
Please make sure your source code can compile. Absolutely no credit if it does not compile.
Please don't include the binary ?les. Do a make clean before submission. You'll make grading harder for us if you do.
Please don't leave out any ?les! You'll make grading harder for us if you do.
Please don't modify any ?les you don't need to! You'll make grading harder for us if you do.
Please don't send us the meta-information from your revision control system! You'll make grading harder for us.
