Subject: [dpdk-dev] [PATCH 2/3] event/dsw: make use of eventdev maintenance facility
Date: Tue, 26 Oct 2021 19:31:47 +0200	[thread overview]
Message-ID: <20211026173148.19399-2-mattias.ronnblom@ericsson.com> (raw)
In-Reply-To: <20211026173148.19399-1-mattias.ronnblom@ericsson.com>

Set the RTE_EVENT_DEV_CAP_REQUIRES_MAINT flag, and perform DSW
background tasks on rte_event_maintain() calls.

RFC v2: Have dsw_event_maintain() occasionally flush the port output
        buffers.
