Hi DPDK Team,   I am trying to run DPDK application in Linux with init level 3 (no gui) and I am observing continuous packet drops on Rx side. But, If I boot Linux in init level 5 (GUI), then I dont see drops.   I have provided linux command line arguments (for isolating the cpu cores and hugepates etc in "GRUB_CMDLINE_LINUX_DEFAULT" variable, and with those it's working fine in init level 5. But, not sureif these configuration are applicable when I boot in Init level 3?  To boot in init level 3, I am setting GRUB_CMDLINE_LINUX="3" , is it correct? If not please suggest what is theother method. Thanks in advance.Anand From iain.barker@oracle.com Tue Apr 10 21:11:51 2018 Return-Path: Received: from userp2130.oracle.com (userp2130.oracle.com [156.151.31.86]) by dpdk.org (Postfix) with ESMTP id 86F541BA93 for ; Tue, 10 Apr 2018 21:11:51 +0200 (CEST) Received: from pps.filterd (userp2130.oracle.com [127.0.0.1]) by userp2130.oracle.com (8.16.0.22/8.16.0.22) with SMTP id w3AJAeMm081650 for ; Tue, 10 Apr 2018 19:11:50 GMT DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=oracle.com; h=mime-version : message-id : date : from : sender : to : subject : content-type : content-transfer-encoding; s=corp-2017-10-26; bh=o2N+ivnkL+n0HRmVycrSrN5od3XW6BmM6zkFBRSRe7E=; b=WASuOj+JI6Sn40LDytKI+74B/qlpADsPvviBAd9oogILf1cpvGz/qBEEi4rSQ1C1US5d gdDwIZNOXfeNYibGI9xyCLY7T3ajhj3jyE70u81T+QldBSb2VVVyNvHyTPj502rDwL6g y50JZyVScCJ+b9UTEXQcNCMyWhonyTX2funr9suZgCx4su5EaZFb8TjZBGlydDhm4aBU C91M+QW3mLv5YLLIQfqMGOc7/QDhwe1byuDwhnzKzB7ot1YOjD9lE9VpWpb5f3iiZoO6 n/GK67SsY2uqmR2SoAqDHIWHiUrk+RIvzzi3tGiBANBUtbdrw5DAyM8FO6iBDr1S5Ahz hA=Received: from userv0021.oracle.com (userv0021.oracle.com [156.151.31.71]) by userp2130.oracle.com with ESMTP id 2h6ne7bwfm-1 (version=TLSv1.2 cipherìDHE-RSA-AES256-GCM-SHA384 bits%6 verify=OK) for ; Tue, 10 Apr 2018 19:11:50 +0000 Received: from userv0121.oracle.com (userv0121.oracle.com [156.151.31.72]) by userv0021.oracle.com (8.14.4/8.14.4) with ESMTP id w3AJBoi4017581 (version=TLSv1/SSLv3 cipher=DHE-RSA-AES256-GCM-SHA384 bits%6 verify=OK) for ; Tue, 10 Apr 2018 19:11:50 GMT Received: from abhmp0009.oracle.com (abhmp0009.oracle.com [141.146.116.15]) by userv0121.oracle.com (8.14.4/8.13.8) with ESMTP id w3AJBnvU016325 for ; Tue, 10 Apr 2018 19:11:50 GMT MIME-Version: 1.0 Message-ID: <64897879-3872-445c-8179-4ea5852e4ecf@default> Date: Tue, 10 Apr 2018 12:11:49 -0700 (PDT) From: Iain Barker Sender: Iain Barker To: users@dpdk.org X-Priority: 3 X-Mailer: Oracle Beehive Extensions for Outlook 2.0.1.9.1 (1003210) [OL 15.0.5023.0 (x86)] Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: quoted-printable X-Proofpoint-Virus-Version: vendor=nai engineY00 definitionsˆ59 signaturesf8698 X-Proofpoint-Spam-Details: rule=notspam policyÞfault score=0 suspectscore=1 malwarescore=0 phishscore=0 bulkscore=0 spamscore=0 mlxscore=0 mlxlogscore™9 adultscore=0 classifier=spam adjust=0 reason=mlx scancount=1 engine=8.0.1-1711220000 definitions=main-1804100182 Subject: [dpdk-users] Wrong OFED version for DPDK 17.11.1 ?

According to the DPDK docs, that's the correct version for DPDK 17.11 Ref: "Mellanox OFED version: 4.2" in https://dpdk.org/doc/guides-17.11/nics/mlx5.html But I get multiple errors which suggest the API versions are incompatible. For example: priv->hw_csum = !!(device_attr_ex.device_cap_flags_ex & IBV_DEVICE_RAW_IP_CSUM); drivers/net/mlx5/mlx5.c:794:21: error: 'struct ibv_device_attr_ex' has no member named 'device_cap_flags_ex' MLNX_OFED_SRC-4.2-1.0.0.0 contains libibverbs-41mlnx1, and that has include/infiniband/verbs.h with the following typedef: struct ibv_device_attr_ex { struct ibv_device_attr orig_attr; uint32_t comp_mask; struct ibv_odp_caps odp_caps; }; So the docs appear to be wrong. no way the OFED 4.2 version of mlx5.c is going to compile against that header. What version of libibverbs should I actually be using for DPDK 17.11.1 ? thanks, Iain
