Improve the existing interrupt handling mechanism by reworking and fixing the exception handlers to ensure proper system responses to CPU exceptions and hardware interrupts.

Scope of work:

  • Exception Handler Rework.
    • Identify Issues:
      • Debug and determine why the current exception handlers are not functioning correctly. - WORKS
    • Implement Robust Exception Handlers:
      • Ensure all CPU exceptions (e.g., divide-by-zero, page faults) are correctly handled.
      • Provide meaningful error messages or codes for different exceptions.
  • Stack Frame and Context Management.
    • Correctly save and restore CPU registers and flags during interrupts.
    • Ensure that the stack is correctly aligned and managed during exception handling.
