3 * Get rid of rox--causes more trouble than it's worth
5 * Reconsider command line arg style--confuses everyone.
7 * pintos script doesn't (always?) delete temp disks
15 * process_death test needs improvement
19 * Improve automatic interpretation of exception messages.
23 - Mark read-only pages as actually read-only in the page table. Or,
24 since this was consistently rated as the easiest project by the
25 students, require them to do it.
27 - Don't provide per-process pagedir implementation but only
28 single-process implementation and require students to implement
29 the separation? This project was rated as the easiest after all.
30 Alternately we could just remove the synchronization on pid
31 selection and check that students fix it.
35 - Need a better way to measure performance improvement of buffer
36 cache. Some students reported that their system was slower with
37 cache--likely, Bochs doesn't simulate a disk with a realistic
42 - Add "Digging Deeper" sections that describe the nitty-gritty x86
43 details for the benefit of those interested.
45 - Add explanations of what "real" OSes do to give students some
52 . Low-level x86 stuff, like paged page tables.
54 . Specifics on how to implement sbrk, malloc.
58 . opendir/readdir/closedir
60 . everything needed for getcwd()
