* [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. Signed-off-by: Shell <smokewood@qq.com> * fixup: address suggestion * fixup: rt_current_thread as global * scheduler: add cpu object for UP scheduler Also, maintain the rt_current_thread in cpu object on UP scheduler. --------- Signed-off-by: Shell <smokewood@qq.com>
