experimental?
Just complaining on the principle, you missed the __rte_experimental
in such a case.
But this API is a no go for me, see below.

This API does not make sense for anything but arm, so this prefix is not good.

On arm, when RTE_ARM_USE_WFE is undefined, why would you need it?
A non exclusive load is enough since you don't want to use wfe.

We are in the RTE_WAIT_UNTIL_EQUAL_ARCH_DEFINED case.
rte_wfe() is always asm volatile("wfe" : : : "memory");

The while() should be with an exclusive load.


I will submit a v12 with those comments addressed so that we move
forward for rc2.
But it won't make it in rc1, sorry.
