Wayne Thornton commented on a discussion on cpukit/score/cpu/x86_64/include/rtems/score/cpu.h: https://gitlab.rtems.org/rtems/rtos/rtems/-/merge_requests/1193#note_150823 > > typedef uintptr_t CPU_Uint32ptr; > > +/** > + * @brief Pauses the CPU pipeline to prevent aggressive speculative > execution > + * and reduce thermal load during spin-wait loops. > + */ > +static inline void _CPU_Pause_speculation( void ) > +{ > + __asm__ volatile( "pause" ::: "memory" ); @gedare I can absolutely open a separate MR to add `_CPU_Spin_wait()` to the `score/cpu.h` file(s) for each BSP that is `RTEMS_SMP` capable. I will note that since each architecture will need a thorough review to determine whether the memory handling and core assignment features are compatible with the API, it will take some time to go through them all. -- View it on GitLab: https://gitlab.rtems.org/rtems/rtos/rtems/-/merge_requests/1193#note_150823 You're receiving this email because of your account on gitlab.rtems.org.
