07/07/2021 07:48, Ruifeng Wang:

Introduce a meson option 'use_wfe' to select wait until equal method.
The default is disable. Traditional polling loop is used.
When enabled, architecture specific mechanism is relied on to do the
wait.

Why do we need an option?
Can it be automatic to enable it when supported?
