(https://bugs.dpdk.org/show_bug.cgi?id=194)\n(for a long term !)\nThis series of patches intend to make vhost PMD available for\nsecondary processes.\nBecause now setting vhost driver to communicate with a vhost-user\nmaster (ex. Qemu) is accomplished by the probe function of the\nprimary process, only the primary process can be a vhost-user\nslave.\nWith this patch, setting vhost driver is delayed at eth_dev\nconfiguration in order to be able to set it from a secondary\nprocess. Because (in the first place,) setting vhost driver is not\nnecessary to be done at probe (it is enough to be done up to eth_dev\nstart), this fix is no problem for the primary process.\nThere is a precondition that the same process has to operate\na vhost interface from begining to end (eth_dev configuration to\neth_dev close). (This patch leaves it to user's responsibility.)\nThis precondition will not be a problem in most use cases\n(including SPP).\n\nItsuro Oda (4):\n net/vhost: remove an unused member\n net/vhost: allocate iface_name from heap\n net/vhost: delay vhost driver setup\n net/vhost: make secondary probe complete\n\n drivers/net/vhost/rte_eth_vhost.c | 152 +++++++++++++++++-------------\n 1 file changed, 88 insertions(+), 64 deletions(-)" }
