Subject: [dpdk-dev] [PATCH v10 0/9] vhost: support inflight share memory protocol feature
Date: Wed, 9 Oct 2019 23:25:06 +0800 [thread overview]
Message-ID: <20191009152515.21765-1-jin.yu@intel.com> (raw)
In-Reply-To: <20191008153341.22228>
This patches introduces two new messages VHOST_USER_GET_INFLIGHT_FD
and VHOST_USER_SET_INFLIGHT_FD to support transferring a shared
buffer between qemu and backend.
Now It can both support split and packed ring. The example code show
how these API work. The test has passed.
How to test the example:
1, Qemu need two patches.
https://patchwork.kernel.org/patch/10766813/
https://patchwork.kernel.org/patch/10861411/(QEMU merged)
it also needs some manual modifications:
we should confirm that before we send get inflight we have already
sent the set features but it seems Qemu didn't do like this. So we
manually revise this, we can add below code in vhost_dev_get_inflight
int r;
r = vhost_dev_set_features(dev, dev->log_enabled);
if (r < 0) {
return -errno;
}
before get_inflight_fd.
2, Guest OS version >= 5.0
3, run the example
4, run the qemu with vhost-user-blk-pci.
eg:
-chardev socket,id=spdk_vhost_blk0,reconnect=1,path=xxxx\
-device vhost-user-blk-pci,ring_packed=on,chardev=spdk_vhost_blk0,num-queues=1\
5, run fio in the guest
6, kill the example and run again.
7, the fio in the guest should continue run without errors.
Jin Yu (9):
vhost: add the inflight description
vhost: add packed ring
vhost: add the inflight structure
vhost: add two new messages to support a shared buffer
vhost: checkout the resubmit inflight information
vhost: add the APIs to operate inflight ring
vhost: add APIs for user getting inflight ring
vhost: add vring functions packed ring support
vhost: add vhost-user-blk example which support inflight
