Subject: [dpdk-dev] [PATCH v2 0/4] deferred queue setup
Date: Fri,  2 Mar 2018 12:13:02 +0800	[thread overview]
Message-ID: <20180302041306.90324-1-qi.z.zhang@intel.com> (raw)
In-Reply-To: <20180212045314.171616-1-qi.z.zhang@intel.com>

According to exist implementation,rte_eth_[rx|tx]_queue_setup will
always return fail if device is already started(rte_eth_dev_start).

This can't satisfied the usage when application want to deferred setup
part of the queues while keep traffic running on those queues already
be setup.

example:
rte_eth_dev_config(nb_rxq = 2, nb_txq =2)
rte_eth_rx_queue_setup(idx = 0 ...)
rte_eth_rx_queue_setup(idx = 0 ...)
rte_eth_dev_start(...) /* [rx|tx]_burst is ready to start on queue 0 */
rte_eth_rx_queue_setup(idx=1 ...) /* fail*/

Basically this is not a general hardware limitation, because for NIC
like i40e, ixgbe, it is not necessary to stop the whole device before
configure a fresh queue or reconfigure an exist queue with no traffic
on it.

The patch let etherdev driver expose the capability flag through
rte_eth_dev_info_get when it support deferred queue configuraiton,
then base on these flag, rte_eth_[rx|tx]_queue_setup could decide
continue to setup the queue or just return fail when device already
started.

v2:
- enhance comment in rte_ethdev.h
