Some\nethdev's need to use an eal event to detect hotplug behaviors. Previously,\nwe needed to register an eal event callback in the application, but this\npotentially causes a race condition between the eal event process to the\nethdev event process. It might better to fix this issue.\n\nThis patch set introduces a way to combine these 2 event by registering\nthe ethdev eal event callback in the ethdev and triggering the ethdev\nhotplug event in the callback. This will let the ethdev device easily\nprocess the hotplug in a common way.\n\nDrivers which support hotplug could use this mechanism to detect and\nprocess hotplugs.\n\npatch history:\nv6->v5:\nrefine some commit log\n\nv5->v4:\nrefine some code style and typo\n\nv4->v3:\nchange to use device event handler install api\n\nv3->v2:\nremove the callback from driver to ethdev for common.\n\nv2->v1:\nadd ixgbe hotplug detect case.\nrefine some doc.\n\nJeff Guo (4):\n ethdev: Add eal device event callback\n net/ixgbe: install ethdev hotplug handler in ixgbe\n net/i40e: install hotplug handler in i40e\n testpmd: remove the dev event callback register\n\n app/test-pmd/testpmd.c | 78 --------------------------------\n doc/guides/rel_notes/release_18_08.rst | 12 +++++\n drivers/net/i40e/i40e_ethdev.c | 8 +++-\n drivers/net/ixgbe/ixgbe_ethdev.c | 8 +++-\n lib/librte_ethdev/rte_ethdev.c | 61 +++++++++++++++++++++++++\n lib/librte_ethdev/rte_ethdev_driver.h | 32 +++++++++++++\n lib/librte_ethdev/rte_ethdev_version.map | 2 +\n 7 files changed, 121 insertions(+), 80 deletions(-)" }
