2025-05-19[smart] Add vDSO support for RISC-V architecture and refactor related componentsbernard
- 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.
2024-09-19feat: smart: user space context optimizationShell
This patch optimizes the user-space context handling in the ARM64 architecture, specifically improving how the context is saved and restored during system calls and interrupts. The changes make the code more efficient and easier to maintain, while ensuring proper preservation of user context during system transitions. Changes: - Introduced a parameter for context saving to improve flexibility. - Replaced hardcoded stack pointer operations with frame-relative references for better readability and code reuse. - Simplified context restoration, removing redundant operations like loading/storing floating-point registers.

2024-07-18[libcpu/arm64] feat: Trimming General ContextShell
This patch focuses on the ARM64 general context handling code. The modifications are aimed at enhancing performance by simplifying context save/restore operations. Changes include: - Adjusted stack alignment in `arch_set_thread_context` function. - Updated `lwp_gcc.S` to reset frame pointer and link register. - Refined `rt_hw_backtrace_frame_unwind` to handle user space address checks. - Added `GET_THREAD_SELF` macro in `asm-generic.h`. - Simplified context saving/restoring in `context_gcc.h` and related files. - Optimized `rt_hw_context_switch_interrupt` and related assembly routines.
