All I added, after seeing that the arg passing works, was comments. Now when I run the tests, the accepted and actual output don't even show up. The message in the title shows up instead.

in process.c, the process created with thread_create does not get scheduled unless I increase the priority

I'm a Professor at Stanford, and I'm teaching an Operating Systems course that uses Pintos for its class projects. I'm writing because an automated search of GitHub identified this repository as possibly containing solutions for the Pintos programming projects. This is a problem for us, because it makes it very easy for students to cheat. Even if they just look at your solution, and don't copy it, that will still reduce the educational experience for them. If this repo does indeed contain Pintos solutions, would you be willing to take it down or at least make it private? If so, that would be a great help to us. If for some reason you absolutely must keep the repository public, it would still be a help if you could rename it so that it doesn't appear in searches for Pintos. Thanks for considering this request.

running:
pintos -v -k -T 60 --qemu --filesys-size=2 -p tests/userprog/args-none -a args-none -- -q -f run args-none

in process.c, start_process, the call to load returns false due to an invalid segment.
pintos tells me: Could not open option rom 'sgabios.bin': No such file or directory
this may or may not be a related error.

This semaphore is the reason why all 76 tests threw the assertion error. Was it right to initialize it to 0?
