Subject: [dpdk-dev] [PATCH v6 1/6] service: fix race condition for MT unsafe service
Date: Wed,  6 May 2020 23:27:59 +0800	[thread overview]
Message-ID: <1588778884-13047-2-git-send-email-phil.yang@arm.com> (raw)
In-Reply-To: <1588778884-13047-1-git-send-email-phil.yang@arm.com>

From: Honnappa Nagarahalli <honnappa.nagarahalli@arm.com>

The MT unsafe service might get configured to run on another core
while the service is running currently. This might result in the
MT unsafe service running on multiple cores simultaneously. Use
'execute_lock' always when the service is MT unsafe.

If the service is known to be mmapped on a single lcore,
setting the service capability to MT safe will avoid taking
the lock and improve the performance.

Fixes: e9139a32f6e8 ("service: add function to run on app lcore")
