Subject: [PATCH 0/5] add LSC and Rxq interrupt for virtio-user
Date: Fri, 3 Mar 2017 17:56:38 +0000 [thread overview]
Message-ID: <1488563803-87754-1-git-send-email-jianfeng.tan@intel.com> (raw)
This is an attempt to add LSC and Rxq interrupt for a virtual device,
virtio-user (with the backend of both vhost-user and vhost-kernel).
HOW TO TEST:
Step 1: start testpmd with a virtual vhost device:
$ testpmd -c 0x3 -n 4 --socket-mem 1024 --no-pci \
--vdev 'eth_vhost0,iface=/tmp/sock0' -- -i
Step 2: start l3fwd-power with a virtio-user device:
$ l3fwd-power -c 0xc -n 4 --socket-mem 1024 --no-pci \
--file-prefix=l3fwd-pwd \
--vdev=virtio_user0,path=/tmp/sock0 \
-- -p 1 -P --config="(0,0,1)" \
--no-numa --parse-ptype
Step 3: start burst in testpmd
(testpmd)> start tx_first
Packets will be received and forwarded back by l3fwd-power.
And l3fwd-power will keep in polling mode.
Step 4: stop burst in testpmd
(testpmd)> stop
l3fwd-power will change to interrupt mode with few CPU
consumption.
Step 5: kill testpmd
$ kill -p `pidof testpmd`
The link status will be changed to down in l3fwd-power.
