Try to understand xv6's
The assigned chapter for today provides a commentary for these files, but you may find it useful to also consult:
Chapter 5 of Intel's system programming guide. Be aware that terms such as exceptions, traps, interrupts, faults and aborts have no standard meaning.
In xv6, set a breakpoint at the beginning of
catch the very first system call. What values are on the stack at
this point? Turn in the output of

This completes the homework.
