- Implemented vDSO functionality for the RISC-V architecture, including the necessary source files and linker scripts. - Introduced a new `vdso_sys.c` file for RISC-V, containing functions to handle time retrieval using the vDSO mechanism. - Created architecture-specific linker scripts (`vdso.lds.S`) for both AArch64 and RISC-V. - Updated the build system to support vDSO compilation for RISC-V, including necessary adjustments in `SConstruct` files. - Refactored existing vDSO code to improve compatibility and maintainability across architectures. - Adjusted the maximum number of PTY devices in the terminal configuration from 64 to 32 for better resource management. - Fixed minor issues in existing code, including correcting the path for the vDSO shared library and ensuring proper function definitions.
