Subject: [dpdk-dev] [PATCH v5 0/2] one way barrier for split vring idx
Date: Thu, 30 Apr 2020 17:14:35 +0800 [thread overview]
Message-ID: <20200430091437.34958-1-joyce.kong@arm.com> (raw)
In-Reply-To: <20200212092456.29433-1-joyce.kong@arm.com>
This patchset replaces the two-way barriers with C11 one-way barriers
for split vring idx, when the frontend and backend are implemented
in software.
By doing PVP benchmarking, the test result of 2c1q showed the throughput
increased 20% with the 0.001% of acceptable loss rate on Thunderx2
platform.[1]
By doing vhost-user + virtio-user case benchmarking, 4% performance gain
was measured on Thunderx2 platform by 2c1q RFC2544 test of 0.001% loss,
and 4.7% performance was improved on Dell platform by 1c1q RFC2544 test
of zero packet loss.[2]

PVP test with virtio 1.0 normal path
v5:
Fix the compling issue when 'CONFIG_RTE_LIBRTE_VIRTIO_DEBUG_DUMP=y'
is enabled.
v4:
Remove some duplicated code comment.
v3:
Modify some style error.
v2:
Add test performance statistics.
