본문내용

쉘 프로그램 수행(50점)
일반 유저 프로그램(쉘 프로그램 포함)을 수행하기 위해 아래 파일의 수정이 필요
src/geekos/user.c
src/geekos/elf.c->기존 Project1에서 구현한 내용을 이용
src/geekos/userseg.c
src/geekos/kthread.c
위 파일의 TODO 함수를 구현할 것.
위 파일을 수정한 후 쉘 프로그램이 동작하는지 확인
main.c에서 shell.exe를 spawn


시스템 콜 구현(50점)
src/geekos/syscall.c
Sys_Exit()
Sys_PrintString()
Sys_GetKey()
Sys_SetAttr()
Sys_GetCursor()
Sys_PutCursor()
Sys_Spawn()
Sys_Wait()
Sys_GetPID()
위 시스템 콜들을 구현

추가구현(Bonus)
vfork()시스템 콜을 추가한 후 간단한 예제 프로그램을 만들어 수행 결과를 보인다.
리눅스 커널 fork.c파일안의 copy_process()함수를 참고
