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. feat: Initial PMM implementation 2025-12-08T16:57:38Z Richard Qin richard.qin.x@gmail.com 2025-12-08T16:57:38Z urn:sha1:c36e1b5e5e069ce1735dcc2a94aa45ba72ea2441 Introduce the foundational Physical Memory Manager (PMM) and restructure the project for modularity. Implemented basic PMM and related memory management headers (mm/pmm.h, mm/vm.h). Updated Makefile and build process to support new modular structure.
