Subject: [dpdk-dev] [PATCH v3 6/6] service: relax barriers with C11 atomics
Date: Fri,  1 May 2020 19:02:45 -0500	[thread overview]
Message-ID: <20200502000245.11071-7-honnappa.nagarahalli@arm.com> (raw)
In-Reply-To: <20200502000245.11071-1-honnappa.nagarahalli@arm.com>

From: Phil Yang <phil.yang@arm.com>

The runstate, comp_runstate and app_runstate are used as guard variables
in the service core lib. To guarantee the inter-threads visibility of
these guard variables, it uses rte_smp_r/wmb. This patch use c11 atomic
built-ins to relax these barriers.
