Function core::arch::arm::__wfe

pub unsafe fn __wfe()

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

Available on ARM only.

Generates a WFE (wait for event) hint instruction, or nothing.

The WFE instruction allows (but does not require) the processor to enter a low-power state until some event occurs such as a SEV being issued by another processor.
