Function core::core_arch::riscv_shared::wfi

pub unsafe fn wfi()

🔬This is a nightly-only experimental API. (stdsimd #48556)

Generates the WFI instruction

The WFI instruction provides a hint to the implementation that the current hart can be stalled until an interrupt might need servicing. This instruction is a hint, and a legal implementation is to simply implement WFI as a NOP.
