[dpdk-dev] [PATCH v4 0/3] Use WFE for spinlock and ring

[Thomas Monjalon]

07/07/2021 07:48, Ruifeng Wang:
> The rte_wait_until_equal_xxx APIs abstract the functionality of 'polling
> for a memory location to become equal to a given value'[1].
> 
> Use the API for the rte spinlock and ring implementations.
> With the wait until equal APIs being stable, changes will not impact ABI.
> 
> Gavin Hu (1):
>   spinlock: use wfe to reduce contention on aarch64
> 
> Ruifeng Wang (2):
>   ring: use wfe to wait for ring tail update on aarch64
>   build: add option to enable wait until equal
