搭建 Mellanox ConnectX-3 EN 10/40 Gbps 网卡 DPDK 运行环境

来源：互联网发布：android ui优化编辑：程序博客网时间：2024/05/18 03:25

DPD v2.0 当前依赖Mlx版本
Mellanox OFED 2.4-1.
Firmware version 2.33.5000 and higher.

1> 编译 mlx4 libraries
http://dpdk.org/download/mlx4/
因要使用 ibv_xxx 系列工具， ibv_xxx 不建议再使用DPDK.org下载的 mlx4 libraries. 可使用 MLNX OFED 内置 mlx4 libraries. 必须采用动态编译方式，方能运行正确.

编译完 MLNX OFED mxl4 libraries , 使用 make install DESTDIR=xxx , 并打包.

2> 编译DPDK v2.0.0

3> 编译mlx4 ofed 内核模块及mstflint程序
http://www.mellanox.com/page/products_dyn?product_family=26&mtag=linux_sw_drivers
注意 MLNX_OFED 2.4-1.0.0 只支持以下OS与内核版本

- RHEL/CentOS 7.0      x86_64/PPC
- SLES11 SP2           x86_64/PPC
- SLES11 SP3           x86_64/PPC
- SLES12               x86_64
- OEL 6.4              x86_64
- OEL 6.5              x86_64
- OEL 6.6              x86_64

- Debian 7.5           x86_64
- Debian 7.6           x86_64
- kernel 3.10.48
- kernel 3.11.10
- kernel 3.14.12
- kernel 3.15.5
- kernel 3.16
- kernel 3.17
- kernel 3.18

Note: 建议使用RHEL相关的内核, 直接可以使用RPM安装相应模块.

编译mlx4内核模块
tar -zxvf mlnx-ofa_kernel-2.4.tgz
cd mlnx-ofa_kernel-2.4
# 配置，当前采用的是RHEL7第一版内核, 可用 yumdownloader --source kernel-3.10.0-123 下载.
./configure --with-mlx4_fc-mod  --with-mlx4_inf-mod --with-core-mod --with-user_mad-mod --with-user_access-mod --with-addr_trans-mod --with-mlx4-mod --with-mlx4_en-mod --with-ipoib-mod --with-srp-mod --with-rds-mod --with-iser-mod --kernel-version=3.10.0-mlx --modules-dir=/lib/modules/3.10.0-mlx/ --kernel-sources=/work/kernel-3.10.0-123.el7.src/linux-3.10.0-123.el7
make
make install # 建议安装，方便建立内核依赖关系

Note: 如为自定义内核配置，CONFIG_INFINIBAND 确认为 'n' 或者 'm', 否则此模块打包进内核在加载mlx4模块时会提示符号冲突.

编译 mft 内核模块，mstflint 使用.
tar -zxvf kernel-mft-3.8.0.tgz
cd kernel-mft-3.8.0
make KPVER=/work/kernel-3.10.0-123.el7.src/linux-3.10.0-123.el7
得到 mst_pciconf.ko  mst_pci.ko

编译 mstflint
tar -zxvf mstflint-3.8.0-1.27.gf3d39b6.tar.gz
cd mstflint-3.8.0
./configure --disable-inband --prefix=/usr
make install

4 . 加载模块

将模块打包并安装到目标机器下

modprobe ib_uverbs

modprobe mlx4_en

modprobe mlx4_core

modprobe mlx4_ib log_num_mgm_entry_size=-1

# 加载mst相关内核

insmod mst_pci.ko

insmod mst_pciconf.ko

运行 ibv_devinfo 获取设备信息

# ibv_devinfo -v
