Subject: [dpdk-dev] [PATCH v2 1/7] eventdev: add API to get service id
Date: Fri, 13 Oct 2017 22:06:44 +0530 [thread overview]
Message-ID: <1507912610-14409-1-git-send-email-pbhagavatula@caviumnetworks.com> (raw)
In-Reply-To: <1507712990-13064-1-git-send-email-pbhagavatula@caviumnetworks.com>
From: Pavan Bhagavatula <pbhagavatula@caviumnetworks.com>
In case of sw event device the scheduling can be done on a service core
using the service registered at the time of probe.
This patch adds a helper function to get the service id that can be used
by the application to assign a lcore for the service to run on.
