[PATCH v4] vhost: add new `rte_vhost_vring_call_nonblock` API

k may happen when SPDK is posting interrupts to VM. Here, we add a new API which allows caller to try again later for this case. Bugzilla ID: 1015 Fixes: c5736998305d ("vhost: fix missing virtqueue lock protection") Signed-off-by: Changpeng Liu --- doc/guides/prog_guide/vhost_

[PATCH] vhost: use try_lock in rte_vhost_vring_call

Note that this function is in data path, so the thread context may not same as socket messages processing context, by using try_lock here, users can have another try in case of VQ's access lock is held by `vhost-events` thread. Signed-off-by: Changpeng Liu --- lib/vhost/vhost.c | 6

[dpdk-dev] [PATCH] eal/hotplug: suppress one error log on primary process

This is a normal case that the primary process already owned one PCI device while the secondary process try to attach it, so suppress the error log here to exclude this case. Signed-off-by: Changpeng Liu --- lib/eal/common/hotplug_mp.c | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions

[dpdk-dev] [PATCH] vhost: return ready when at least 1 vring is configured

at least 3 vrings, and virtio_net needs at least 2 vrings, virtio_blk needs at least 1 vring. So instead of doing it in vhost library it's better that the application who uses this library do this check. Signed-off-by: Changpeng Liu --- lib/librte_vhost/vhost_user.c | 2 +- 1 file changed, 1
