Operating System Design Project - 4PMISEX2

Goal(s)

To study the basics of designing an operating system kernel and writing "low-level" code that achieves the interaction between the system and the hardware (a machine with a RISCV processor). The notion of time-sharing is introduced through the implementation of a preemptive scheduling mechanism for light processes.

Content(s)

The entire project is done on a RISCV-based platform emulated by qemu.
1. Write a display driver, serial interface at first, then manage a PCI express controller and video card.
2. Time management via hardware clock
3. Design a simple process scheduling mechanism, create the processes, explicitly switch context, and then switch context triggered by the hardware clock.
4. Mechanism of dormancy of processes, termination 5. Possible extensions: synchronization, input drivers, virtual memory,...
