myOS
I use many operating systems all day but can't clearly understand how they work and are implemented as a whole. This project is to write a very simple kernel so that I can figure out the key concepts and principles of an OS.
Key Features
- Multi-processing
- Paging system (virtual memory management)
- A file system
- Different types of syscalls
- Interrupts handling
- etc.

When myOS boots
A simple shell lvsh
- lvsh has some builtin commands: ps, ls, mm, etc.
- Can also execute a binary form it and pass command line args to the process.
A simple software cat (yes, it is the cat on Linux XD)
A software nothing used to test
Use nothing to trigger a page fault
