Some ethdev need to use eal event to detect hotplug\nbehaviors, the privors way is register eal event callback in app, but seems\nthat it will have some race between these 2 event processes. In oder to fix\nthe it, it might be better to find a way to combind these 2 events detect.\n\nThis patch set introduce a way to combind these 2 event, by register the\nethdev eal event callback in ether dev and trigger the ethdev hotplug event\nin the callback. That will let the ethdev device can easy process hotplug\nby a common way.\n\nHere let i40e/ixgbe pmd driver for example, other driver which support\nhotplug feature could be use this way to detect and process hotplug.\n\npatch history:\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 | 76 --------------------------------\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 | 59 +++++++++++++++++++++++++\n lib/librte_ethdev/rte_ethdev_driver.h | 32 ++++++++++++++\n lib/librte_ethdev/rte_ethdev_version.map | 2 +\n 7 files changed, 119 insertions(+), 78 deletions(-)", "headers": { "Return-Path": "<dev-bounces@dpdk.org>", "X-Original-To": "patchwork@dpdk.org", "Delivered-To": "patchwork@dpdk.org", "Received": [ "from [92.243.14.124] (localhost [127.0.0.1])\n\tby dpdk.org (Postfix) with ESMTP id 36D071B3A3;\n\tWed, 11 Jul 2018 14:00:52 +0200 (CEST)", "from mga04.intel.com (mga04.intel.com [192.55.52.120])\n\tby dpdk.org (Postfix) with ESMTP id 1514E1B173\n\tfor <dev@dpdk.org>; Wed, 11 Jul 2018 14:00:49 +0200 (CEST)", "from fmsmga008.fm.intel.com ([10.253.24.58])\n\tby fmsmga104.fm.intel.com with ESMTP/TLS/DHE-RSA-AES256-GCM-SHA384;\n\t11 Jul 2018 05:00:49 -0700", "from jeffguo-z170x-ud5.sh.intel.com (HELO localhost.localdomain)\n\t([10.67.104.10])\n\tby fmsmga008.fm.intel.com with ESMTP; 11 Jul 2018 05:00:46 -0700" ], "X-Amp-Result": "SKIPPED(no attachment in message)", "X-Amp-File-Uploaded": "False", "X-ExtLoop1": "1", "X-IronPort-AV": "E=Sophos;i=\"5.51,338,1526367600\"; d=\"scan'208\";a=\"54214708\"", "From": "Jeff Guo <jia.guo@intel.com>", "To": "stephen@networkplumber.org, bruce.richardson@intel.com,\n\tferruh.yigit@intel.com, konstantin.ananyev@intel.com,\n\tgaetan.rivet@6wind.com, jingjing.wu@intel.com, thomas@monjalon.net,\n\tmotih@mellanox.com, matan@mellanox.com, harry.van.haaren@intel.com,\n\tqi.z.zhang@intel.com, shaopeng.he@intel.com,\n\tbernard.iremonger@intel.com, arybchenko@solarflare.com", "Cc": "jblunck@infradead.org, shreyansh.jain@nxp.com, dev@dpdk.org,\n\tjia.guo@intel.com, helin.zhang@intel.com", "Date": "Wed, 11 Jul 2018 19:58:28 +0800", "Message-Id": "<1531310312-12273-1-git-send-email-jia.guo@intel.com>", "X-Mailer": "git-send-email 2.7.4", "In-Reply-To": "<1530787185-5915-1-git-send-email-jia.guo@intel.com>", "References": "<1530787185-5915-1-git-send-email-jia.guo@intel.com>", "Subject": "[dpdk-dev] [PATCH v5 0/4] Install eal hotplug event handler in\n\ti40e/ixgbe", "X-BeenThere": "dev@dpdk.org", "X-Mailman-Version": "2.1.15", "Precedence": "list", "List-Id": "DPDK patches and discussions <dev.dpdk.org>", "List-Unsubscribe": "<https://mails.dpdk.org/options/dev>,\n\t<mailto:dev-request@dpdk.org?subject=unsubscribe>", "List-Archive": "<http://mails.dpdk.org/archives/dev/>", "List-Post": "<mailto:dev@dpdk.org>", "List-Help": "<mailto:dev-request@dpdk.org?subject=help>", "List-Subscribe": "<https://mails.dpdk.org/listinfo/dev>,\n\t<mailto:dev-request@dpdk.org?subject=subscribe>", "Errors-To": "dev-bounces@dpdk.org", "Sender": "\"dev\" <dev-bounces@dpdk.org>" }, "addressed": null } ]
