Lab1 : Compiling a Custom Linux Kernel & Implementing New System Calls

compile the Linux kernel for a RISC-V environment.
Run a minimal Linux kernel for testing, Compile a custom Linux kernel from source, Add a new Linux system call, Create a kernel patch.

Lab2 : Scheduling Policy Demonstration Program

Linux Scheduling Policy

• Fair scheduing policies => (SCHED_NORMAL, SCHED_NORMAL)
• Real-Time scheduing policies => (SCHED_FIFO, SCHED_RR)
• Idle scheduling policy => (SCHED_IDLE)
  implement a program to apply different scheduling policies on created threads and observe their behaviors.

Lab3 : System Information Fetching Kernel Module

implement a kernel module that fetches the system information from the kernel.
