Gedare Bloom started a new discussion on cpukit/score/cpu/x86_64/include/rtems/score/cpu.h: https://gitlab.rtems.org/rtems/rtos/rtems/-/merge_requests/1193#note_150615 > > 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" ); there is already `amd64_spinwait()` I like the idea of generalizing this for other architectures though, so I'm happy with the new function. Maybe we should go with `_CPU_Spin_wait()` though. I believe there is `pause` in riscv also, and arm's `yield` function looks similar. -- View it on GitLab: https://gitlab.rtems.org/rtems/rtos/rtems/-/merge_requests/1193#note_150615 You're receiving this email because of your account on gitlab.rtems.org.
