For project 2, you will be fleshing out the system call framework, implementing process exit and wait, wrapping file system calls with a file descriptor interface and validating user supplied arguments to the system calls. Since Pintos is designed for 80x86 architecture, at the end of the projects, you could run theoretically the OS that you built on a regular IBM-compatible PC! Of course, during development, running Pintos on bare metal machines each time could be time consuming.

Project Documents The following is a list of the documents to explain and document the project and its requirements. loader. 1 Design Document (Due 2/20) and Design Review Before you start writing any code for your project, you should create an implementation plan for each feature and convince yourself that your design is correct. But this design is sufficient for current requirements. h The kernel loader. In the Pintos projects, you and your project team will strengthen its support in all three of these areas. If you call malloc, you must check the result to make sure the system did not run out of memory (and you must do something reasonable if memory does run out).
