Makefile

Completed using: Linux Mint Cinnamon distro VM && Lab computer # 24
To Build:
./Part_One/gcc -o part1.x part1.c
./Part_Two/make
./Part_Three/test_kernel/elevator/make

To Clean:
./Part_Two/make clean
./Part_Three/test_kernel/elevator/make clean

To Run Parts:

• Part One (in Part_One):

• strace -o log part1.x

• Part Two (in Part_Two):

• insmod x_time

  cat /proc/timed

• Part Three make

  navigate to src folder

  sudo insmod elevator.ko

  ./../elevator_driver/consumer.x --start

  ./../elevator_driver/producer.x

  ./../elevator_driver/consumer.x --stop

Known Bugs:

1. Deadlocks
2. Can add people to the list but elevator not detecting the request (deadlocking at request).
3. Not properly printing out status after adding things to the list.
4. Threads aren't stopping properly upon exiting the module.
5. Elevator is not moving.

Unfinished Portions:

1. Adding people to list, all other logic is present.

Additional Comments:

1. We assumed that the messages wouldn't consume more than 2048 bytes for characters
