| * | Fix: critical malloc size calculation bug | Richard Qin | 2026-01-03 | 5 | -0/+0 |
| | | | | | | | | | | | Summary: - Fixed an integer arithmetic error in malloc() where 'nunits' was initialized to 0, causing incorrect heap sizing. - This bug caused malloc to return pointers pointing to unmapped memory pages, leading to Store Page Fault (scause 15) at process boundaries. - Switched memory allocator logic to use byte-based size calculation instead of K&R style units to prevent off-by-one errors. Improvements: - Shell now starts successfully without segfaults. | ||||

| * | feat: Add initial Supervisor Mode Trap Handler | Richard Qin | 2025-12-10 | 4 | -0/+0 |
| | | | | | | | | | | | 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. | ||||
