HI, support team: I want to add WFE when running in the loop of _tx_thread_schedule in SMP threadx system. and release SEV when task ready, would you please tell me where to add the WFE and SEV instruction?

The first place to look is the TX_ENABLE_WFI logic. An example can be found in the ThreadX Cortex-A5x SMP ports. The wait here is released by _tx_thread_smp_core_preempt via the macro TX_THREAD_SMP_WAKEUP_LOGIC. Of course, this logic could be modified to meet your needs.
