- How about `diff' and `cmp' programs?
-* Make it clear that the students own their code, because there was some
- confusion on that point.
-
* Threads:
- - join-invalid doesn't compile if tid_t is not scalar type.
-
- mlfqs tests suck. They aren't even correct, e.g. the amarv
submission from win0405 is graded incorrectly.
project 3 and in real OSes. Also revise the grading criteria to
match.
- - Move `join' implementation here, from `threads' project, to help
- normalize the project difficulties.
-
- - The semantics of the join system call should change so that it
- only returns the exit code once.
-
- 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.
Alternatively, shrink the inode size.
- - Add mkdir and ls example user programs.
-
- Add option to disable buffer cache.
- - Get rid of "dump" commands--they're not really useful.
-
- Sample solution.
- Need a better way to measure performance improvement of buffer
* Code:
- - Rewrite quick_sort() to use heap sort, for O(1) stack usage.
+ - Make threads test use a program and arguments like the other
+ projects.
+
+ - Revise command-line arguments for sensibility instead of for
+ Nachos compatibility.
+
+ - Get rid of all compile-time flags, e.g. MLFQS should be a runtime
+ command-line option.
- - Rewrite list_sort() to use merge sort, for O(1) heap usage.
+ - Need an optimization barrier and an explanation of it in the
+ documentation.
- - Make list_elem and hash_elem a struct, by encapsulating a struct
- list_elem inside a struct hash_elem as a member.
+ - Need to check the wait system call more thoroughly.
