Subject: [dpdk-stable] [PATCH v3 0/4] make vhost PMD available for secondary processes
Date: Thu,  6 Feb 2020 10:39:32 +0900	[thread overview]
Message-ID: <20200206013936.11119-1-oda@valinux.co.jp> (raw)
In-Reply-To: <20200108062510.3478-1-oda@valinux.co.jp>

vhost PMD has not been available for secondary processes since
DPDK v18.11.  (https://bugs.dpdk.org/show_bug.cgi?id=194)
(for a long term !)
This series of patches intend to make vhost PMD available for
secondary processes.
Because now setting vhost driver to communicate with a vhost-user
master (ex. Qemu) is accomplished by the probe function of the
primary process, only the primary process can be a vhost-user
slave.
With this patch, setting vhost driver is delayed at eth_dev
configuration in order to be able to set it from a secondary
process. Because (in the first place,) setting vhost driver is not
necessary to be done at probe (it is enough to be done up to eth_dev
start), this fix is no problem for the primary process.
There is a precondition that the same process has to operate
a vhost interface from beginning to end (from eth_dev configuration
to eth_dev close). (This patch leaves it to user's responsibility.)
This precondition will not be a problem in most use cases
(including SPP).

v2:
- add signed-off-by
- fix spelling error

v3:
- rebase on dpdk-next-virtio master
- change patch order
- fix subject and commit message

Itsuro Oda (4):
  net/vhost: allocate interface name from heap
  net/vhost: delay vhost driver setup
  net/vhost: make secondary probe complete
  net/vhost: remove an unused member
