| * | feat: Add initial Supervisor Mode Trap Handler | Richard Qin | 2025-12-10 | 12 | -17/+310 |
| | | | | | | | | | | | Implement the initial mechanism for handling traps and exceptions in Supervisor Mode. Set up the stvec Control and Status Register (CSR) to direct all S-Mode Traps (Interrupts and Exceptions) to a unified assembly entry point. Implemented assembly code for saving and restoring the Trap Context (register state). Provides the foundational framework necessary for future Timer Interrupts and System Calls. | ||||
