Introduction - - The purpose of this document is to illustrate how to build DMM and run applications on it. - -Note: - - Users can easily build DMM by running DMM/scripts/build.sh, which contains following steps. - -# 2. Build DPDK - - DPDK needs to be built first for DMM RTE memory dependency. - -- Steps: - - Download dpdk-18.02.tar.xz from DPDK release, you can get it from [http://static.dpdk.org/rel](http://static.dpdk.org/rel) - -```sh - wget http://static.dpdk.org/rel/dpdk-18.02.tar.xz - tar xvf dpdk-18.02.tar.xz - vi dpdk-18.02/config/common_base - //make CONFIG_RTE_BUILD_SHARED_LIB=y, CONFIG_RTE_EXEC_ENV=y, CONFIG_RTE_LIBRTE_EAL=y, CONFIG_RTE_EAL_PMD_PATH="/tmp/dpdk/drivers/" - cd dpdk-18.02 - make install T=x86_64-native-linuxapp-gcc DESTDIR=/usr -j 4 - cd x86_64-native-linuxapp-gcc - make # install the dpdk which will generate .so inside lib folder in the path. - mkdir -p /tmp/dpdk/drivers/ - cp -f /usr/lib/librte_mempool_ring.so /tmp/dpdk/drivers/ -``` - -Note: - Under certain kernel versions (e.g. v3.10.0 adopted by CentOS 7.5), compiling DPDK with default - configuration will encounter errors like below. - `error: unknown field 'ndo_change_mtu' specified in initializer .no_change_mtu = kni_net_change_mtu` - This is caused by `kni` compiling, disable `kni` in dpdk config file will figure it out. - Actually, we have tested ubuntu 14.04 ~ 16.04, CentOS 7.2, and they worked well. - -# 3. Build DMM - -```sh - cd $(DMM_DIR)/thirdparty/glog/glog-0.3.4/ && autoreconf -ivf - cd $(DMM_DIR)/build - cmake .. -``` - -Note: - $(DMM_DIR) is the directory where dmm has been cloned. - After cmake all the makefiles and dependent .sh files will be copied under build directory. - -```sh - make -j 8 -``` - - Then we can get libnStackAPI.so - - For centos we can use the command 'make pkg-rpm' to generate the rpm package in release/rpm. - -# 4. Build rsocket - -```sh - cd $(DMM_DIR)/build - make dmm_rsocket -``` - -Note: - Make sure Mellanox OFED has been installed in your computer, or run the following command before compiling - -```sh - cd $DMM_DIR/stacks/rsocket - #Take ubuntu16.04 as an example, the tgz file has the format MLNX_OFED_LINUX-<ver>-<OS label><CPU arch>.tgz - wget http://www.mellanox.com/downloads/ofed/MLNX_OFED-4.4-1.0.0.0/MLNX_OFED_LINUX-4.4-1.0.0.0-ubuntu16.04-x86_64.tgz - tar -zxvf MLNX_OFED_LINUX-4.4-1.0.0.0-ubuntu16.04-x86_64.tgz - cd MLNX_OFED_LINUX-4.4-1.0.0.0-ubuntu16.04-x86_64 - ./mlnxofedinstall --force -``` - -# 5. Env Setting - -- Hugepage setting: - -```sh - sudo sysctl -w vm.nr_hugepages=1024 -``` - -Check hugepage info - -```sh - cat /proc/meminfo -``` - -- Mount hugepages: - -```sh - sudo mkdir -p /mnt/nstackhuge/ - sudo mount -t hugetlbfs -o pagesize=2M none /mnt/nstackhuge/ - sudo mkdir -p /var/run/ip_module -``` - -# 6. Build and Run the APP - -- Link the app with the lib **libnStackAPI.so** first, you can refer to app_example/perf-test - -- Enable detail log of nstack by setting env var - -```sh - export LD_LIBRARY_PATH=/dmm/release/lib64 - export NSTACK_LOG_ON=DBG -``` - -- Copy and update the module_config.json, rd_config.json into the same folder of app - -- Run your app |
