Subject: [dpdk-dev] [PATCH v2 6/8] test/mempool_perf: use GCC atomic builtins for lcores sync
Date: Tue, 15 Jun 2021 21:54:57 -0500 [thread overview]
Message-ID: <20210616025459.22717-7-joyce.kong@arm.com> (raw)
In-Reply-To: <20210616025459.22717-1-joyce.kong@arm.com>
Convert rte_atomic usages to GCC atomic builtins for lcores sync
in mempool_perf testcases. Meanwhile, remove unnecessary synchro
init as it would be set to 0 when launching cores.
