As these structures contain\n> lists of timers, new APIs are introduced that allow a caller to specify\n> the particular structure instance into which a timer should be inserted\n> or from which a timer should be removed. This enables primary and\n> secondary processes to modify the same timer list, which enables some\n> multi-process use cases that were not previously possible; e.g. a\n> secondary process can start a timer whose expiration is detected in a\n> primary process running a new flavor of timer_manage().\n> \n> The original library API is mostly unchanged, though implementations are\n> updated to call into newly added functions with a default structure\n> instance ID that provides the original behavior. New functions are\n> introduced to enable applications to allocate structure instances to\n> house timer lists, and to reference them with an identifier when\n> starting and stopping timers, and finally, to manage the timer lists\n> referenced with an identifier.\n> \n> My initial performance testing with the \"timer_perf_autotest\" test shows\n> no performance regression or improvement, and inspection of the\n> generated optimized code shows that the extra function call gets inlined\n> in the functions that now have an extra function call. \n> \n> Erik Gabriel Carrillo (2):\n> timer: allow timer management in shared memory\n> timer: add function to stop all timers in a list\n\nApplied with meson fix, thanks", "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 5B5171B8B8;\n\tWed, 17 Apr 2019 21:54:10 +0200 (CEST)", "from out3-smtp.messagingengine.com (out3-smtp.messagingengine.com\n\t[66.111.4.27]) by dpdk.org (Postfix) with ESMTP id F06BC1B8B5\n\tfor <dev@dpdk.org>; Wed, 17 Apr 2019 21:54:07 +0200 (CEST)", "from compute1.internal (compute1.nyi.internal [10.202.2.41])\n\tby mailout.nyi.internal (Postfix) with ESMTP id 80D3D21C08;\n\tWed, 17 Apr 2019 15:54:07 -0400 (EDT)", "from mailfrontend2 ([10.202.2.163])\n\tby compute1.internal (MEProxy); Wed, 17 Apr 2019 15:54:07 -0400", "from xps.localnet (184.203.134.77.rev.sfr.net [77.134.203.184])\n\tby mail.messagingengine.com (Postfix) with ESMTPA id 665FB103CB;\n\tWed, 17 Apr 2019 15:54:06 -0400 (EDT)" ], "DKIM-Signature": [ "v=1; a=rsa-sha256; c=relaxed/relaxed; d=monjalon.net; h=\n\tfrom:to:cc:subject:date:message-id:in-reply-to:references\n\t:mime-version:content-transfer-encoding:content-type; s=mesmtp;\n\tbh=kysazD+8+VvjFCOW/IM0kPDCAFucVl5+dy/0aGSqCkE=; b=Dgy20FQ/Z+a5\n\tV1B3ZmC+OmfTQl+TJKr0cVuhFf6vsOfAWFz6g48xFEPnMGILi/R3SLuNHJwUtoNx\n\tLz6uD9rFjh6QLaBFAV6BpMnjIBmqtylo/WSankO0sS9W5IyJZeAjMYKMUeXZy4w5\n\tkl/YfI+WyfAmCxK4pF62LNOaPEyiGUA=", "v=1; a=rsa-sha256; c=relaxed/relaxed; d=\n\tmessagingengine.com; h=cc:content-transfer-encoding:content-type\n\t:date:from:in-reply-to:message-id:mime-version:references\n\t:subject:to:x-me-proxy:x-me-proxy:x-me-sender:x-me-sender\n\t:x-sasl-enc; s=fm2; bh=kysazD+8+VvjFCOW/IM0kPDCAFucVl5+dy/0aGSqC\n\tkE=; b=QByAJq6aSWCM6doPQ+3xyk0D+BklGrTFp9o3wM8NI34KSCR/7lDjniM3Y\n\tAt7EsXzb1aJrBzIicawCxjJN8xT5l/jbjv+whjtFd6LSts9bffldl4Cii3cdExQp\n\t245hxur7GrO2XLMuTFzoR+XcuUxWkjTLwyJyR7E6GITE3zmkOThxGWqx46rwj7JS\n\tb8tfMukk0DYZa2OhgLCy4mdaPAwhl1Lrg/feq92AbN6fpYOBWf44WH3RpDkUR6L8\n\t2tqEBO+oomt5GxUftthDBvHZvoigPVG+Zkb0MX8oBAy2nbXFDtQX7eaF2xPbqmwh\n\tFE5mkNb8wzMkOX17gVUcHC3lm3wfQ==" ], "X-ME-Sender": "<xms:XoS3XF-5atnrIasssla5tQAnLBm8UezTfHNGWvBWEwcxFOoAWnkUPw>", "X-ME-Proxy-Cause": "gggruggvucftvghtrhhoucdtuddrgeduuddrfeefgddugeduucetufdoteggodetrfdotf\n\tfvucfrrhhofhhilhgvmecuhfgrshhtofgrihhlpdfqfgfvpdfurfetoffkrfgpnffqhgen\n\tuceurghilhhouhhtmecufedttdenucesvcftvggtihhpihgvnhhtshculddquddttddmne\n\tcujfgurhephffvufffkfgjfhgggfgtsehtufertddttddvnecuhfhrohhmpefvhhhomhgr\n\tshcuofhonhhjrghlohhnuceothhhohhmrghssehmohhnjhgrlhhonhdrnhgvtheqnecukf\n\thppeejjedrudefgedrvddtfedrudekgeenucfrrghrrghmpehmrghilhhfrhhomhepthhh\n\tohhmrghssehmohhnjhgrlhhonhdrnhgvthenucevlhhushhtvghrufhiiigvpedt", "X-ME-Proxy": "<xmx:X4S3XFjnVmfR9gV0jP9cX2jSdmZxjZnW1V7ePlD-n53bkwdN0vTPFg>\n\t<xmx:X4S3XJe0YMSXlH2-sP4dwlQK-B7zWVUFMJe3cD62rY_yS8V6LuSNTw>\n\t<xmx:X4S3XGKTy4B3g5invBOgAIZEscu5HiKAtr-4gLl-n3FknAYOy6m8pw>\n\t<xmx:X4S3XJT-u8WqB-uQS4ZLc_gRAJGnnKm667MH01EK-w9g-UjTgtN89A>", "From": "Thomas Monjalon <thomas@monjalon.net>", "To": "Erik Gabriel Carrillo <erik.g.carrillo@intel.com>", "Cc": "dev@dpdk.org, rsanford@akamai.com", "Date": "Wed, 17 Apr 2019 21:54:04 +0200", "Message-ID": "<1642111.88Saxy7NWj@xps>", "In-Reply-To": "<1555364488-28207-1-git-send-email-erik.g.carrillo@intel.com>", "References": "<1551892822-23967-1-git-send-email-erik.g.carrillo@intel.com>\n\t<1555364488-28207-1-git-send-email-erik.g.carrillo@intel.com>", "MIME-Version": "1.0", "Content-Transfer-Encoding": "7Bit", "Content-Type": "text/plain; charset=\"us-ascii\"", "Subject": "Re: [dpdk-dev] [PATCH v5 0/2] Timer library changes", "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 } ]
