feat: smart: user space context optimization

2024-09-20T03:02:39Z

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.

feat: arm64: generic implementation of vector irq (#9336)

2024-08-27T04:45:12Z

feat: overall implementation of vector irq This patch generalize the irq handling on up/mp system by adding the `rt_hw_irq_exit()` & `rt_hw_vector_irq_sched()` API. Changes: - Added `rt_hw_irq_exit()` and `rt_hw_vector_irq_sched()` APIs for unified IRQ management. - Refactored assembly code for both UP and MP systems to use the new IRQ handling flow. - Removed redundant code and optimized exception handling paths.
