Subject: Re: [dpdk-dev] [RFC PATCH] vhost: remove lockless enqueue to virt ring
Date: Thu, 5 Nov 2015 10:21:41 +0000 [thread overview]
Message-ID: <C37D651A908B024F974696C65296B57B4B16D482@SHSMSX101.ccr.corp.intel.com> (raw)

If no objections, would remove the internal cmpset enqueue, should get
some improved performance.
No idea why commit message is lost:
DPDK doesn't support receiving/transmitting packets from/to the same
port/queue.
Vhost pmd wraps vhost device as normal dpdk port. dpdkvhost based
applications/switch
also treate virtio port and physical port both as ports, and have
their own
lock implmentation when to enqueue packets to the same port. This patch
removes
the internal lockless vhost enqueue implmentation.
