Subject: [dpdk-dev] [PATCH v5 0/2] provide rte_pktmbuf_alloc_bulk API and call it in vhost dequeue
Date: Mon, 28 Dec 2015 00:38:21 +0800	[thread overview]
Message-ID: <1451234303-54212-1-git-send-email-huawei.xie@intel.com> (raw)
In-Reply-To: <1450049754-33635-1-git-send-email-huawei.xie@intel.com>

v5 changes:
 add comment about duff's device and our variant implementation

v4 changes:
 fix a silly typo in error handling when rte_pktmbuf_alloc fails

v3 changes:
 move while after case 0
 add context about duff's device and why we use while loop in the commit
message

v2 changes:
 unroll the loop in rte_pktmbuf_alloc_bulk to help the performance

For symmetric rte_pktmbuf_free_bulk, if the app knows in its scenarios
their mbufs are all simple mbufs, i.e meet the following requirements:
 * no multiple segments
 * not indirect mbuf
 * refcnt is 1
 * belong to the same mbuf memory pool,
it could directly call rte_mempool_put to free the bulk of mbufs,
otherwise rte_pktmbuf_free_bulk has to call rte_pktmbuf_free to free
the mbuf one by one.
This patchset will not provide this symmetric implementation.

Huawei Xie (2):
  mbuf: provide rte_pktmbuf_alloc_bulk API
  vhost: call rte_pktmbuf_alloc_bulk in vhost dequeue
