Subject: [dpdk-dev] Use WFE for spinlock and ring
Date: Sun, 25 Apr 2021 05:56:51 +0000	[thread overview]
Message-ID: <20210425055653.1509261-1-ruifeng.wang@arm.com> (raw)
In-Reply-To: <20200424070741.16619-1-gavin.hu@arm.com>

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.

  spinlock: use wfe to reduce contention on aarch64
