-* The p1-4.c testcase needs significant tuning. Currently it takes
- too long (especially when SHOW_PROGRESS is turned on) and doesn't
- show significant improvement.
+* Get rid of rox--causes more trouble than it's worth
-* The semantics of the join system call should change so that it only
- returns the exit code once.
+* Reconsider command line arg style--confuses everyone.
+
+* pintos script doesn't (always?) delete temp disks
+
+* Finish writing tour.
+
+
+
+
+
+* process_death test needs improvement
+
+* Internal tests.
+
+* Improve automatic interpretation of exception messages.
+
+* Userprog project:
+
+ - Mark read-only pages as actually read-only in the page table. Or,
+ since this was consistently rated as the easiest project by the
+ students, require them to do it.
+
+ - Don't provide per-process pagedir implementation but only
+ single-process implementation and require students to implement
+ the separation? This project was rated as the easiest after all.
+ Alternately we could just remove the synchronization on pid
+ selection and check that students fix it.
+
+* Filesys project:
+
+ - Need a better way to measure performance improvement of buffer
+ cache. Some students reported that their system was slower with
+ cache--likely, Bochs doesn't simulate a disk with a realistic
+ speed.
+
+* Documentation:
+
+ - Add "Digging Deeper" sections that describe the nitty-gritty x86
+ details for the benefit of those interested.
+
+ - Add explanations of what "real" OSes do to give students some
+ perspective.
+
+* Assignments:
+
+ - Add extra credit:
+
+ . Low-level x86 stuff, like paged page tables.
+
+ . Specifics on how to implement sbrk, malloc.
+
+ . Other good ideas.
+
+ . opendir/readdir/closedir
+
+ . everything needed for getcwd()
