[libcpu/arm64] add C11 atomic ticket spinlock (#8882)

2024-05-16T07:45:12Z

* [libcpu/arm64] add C11 atomic ticket spinlock Replace the former implementation of flag-based spinlock which is unfair Besides, C11 atomic implementation is more readable (it's C anyway), and maintainable. Cause toolchain can use their builtin optimization and tune for different micro-architectures. For example armv8.5 introduces a better instruction. The compiler can help with that when it knows your target platform in support of it. Signed-off-by: Shell * fixup: RT_CPUS_NR --------- Signed-off-by: Shell

[src] add rt_hw_cpu_id() wrapper API (#8894)

2024-05-08T01:22:09Z

* [src] add rt_hw_cpu_id() wrapper API rt_hw_cpu_id() is an unsafe API which should not be used by most codes directly. It's error-prone because it must be used in proper context, otherwise it can lead to errors and unpredictable behavior. This patch adds a wrapper API for rt_hw_cpu_id() to address this risk. It includes the context-checking functionality and provides a safer alternative for obtaining CPU IDs, ensuring that it is used correctly within the appropriate context.
