[arm64] add hw thread self (#8942)

2024-05-28T06:27:55Z

* [libcpu] arm64: Add hardware thread_self support This patch introduces hardware-based thread self-identification for the AArch64 architecture. It optimizes thread management by using hardware registers to store and access the current thread's pointer, reducing overhead and improving overall performance. Changes include: - Added `ARCH_USING_HW_THREAD_SELF` configuration option. - Modified `rtdef.h`, `rtsched.h` to conditionally include `critical_switch_flag` based on the new config. - Updated context management in `context_gcc.S`, `cpuport.h` to support hardware-based thread self. - Enhanced `scheduler_mp.c` and `thread.c` to leverage the new hardware thread self feature. These modifications ensure better scheduling and thread handling, particularly in multi-core environments, by minimizing the software overhead associated with thread management.

[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
