Subject: [dpdk-dev] [PATCH 15/39] event/octeontx: add support dequeue timeout tick conversion
Date: Fri,  3 Mar 2017 22:57:57 +0530	[thread overview]
Message-ID: <1488562101-6658-16-git-send-email-jerin.jacob@caviumnetworks.com> (raw)
In-Reply-To: <1488562101-6658-1-git-send-email-jerin.jacob@caviumnetworks.com>

SSO co-processor runs at a different frequency than core clock.
Request PF to convert the ns to SSO get_work timeout period.
On dequeue, If device is configured with
RTE_EVENT_DEV_CFG_PER_DEQUEUE_TIMEOUT configuration then
use different fast path dequeue handler to wait till requested
amount of nanosecond if the event is not available.
