Web1.Take a look at the Project User Programs test suite in src/tests/userprog. Some of the test cases will intentionally provide invalid pointers as syscall arguments, in order to test whether your implementation WebFrom the userprog/build directory, execute pintos-mkdisk filesys.dsk--filesys-size=2. This command creates a simulated disk named lesys.dsk that contains a 2 MB Pintos le system partition. Then format the le system partition by passing -f -q on the kernel’s command line: pintos -f -q. The -f option causes the le system to be formatted, and -q ... duplicate current line or selected block
