Omregga inte i webreg
Typ på torsdag
- maila filippe [sic?] angående status
- Gör gammla eller nya labbar
- lab 0 uppdaterad
- Lab3 delad i 3
- fler kodexempel
----------------------------------------
- 29 mars lab deadline
- labbar lämnas kanske inte via gitlab
== Tekniskt om pintos ==
- Return från syscall ligger i `f->eax`
- `f->esp` is the stack of the calling process
- The syscall number is ath the top, then the arguments
- `0xCC` means that memmory was `free()`d
- `backtrace kernel [ hexcode ] ...`
- gdb `x/{5w,s}` examine...?
== Debug ==
