DPDK - gsg文档(介绍与编译)

&& Hugepage

  提前分配hugepage内存,可以减少虚拟页地址转换到物理地址所需的时间。

  相关命令:

    在虚拟机上运行时,在没有NUMA的机器上,执行“echo 1024 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages”,有NUMA的机器上执行“echo 1024 > /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages和echo 1024 > /sys/devices/system/node/node1/hugepages/hugepages-2048kB/nr_hugepages

    

 

&& 编译

  cd dpdk-[version]

  make install T=x86_64-native-linuxapp-gcc

  make config T=x86_64-linuxapp-gcc

&& 编译helloworld

  cd examples/helloworld/
  export RTE_SDK=$HOME/DPDK
  export RTE_TARGET=x86_64-native-linuxapp-gcc

  *RTE_SDK - Points to the DPDK installation directory.
  *RTE_TARGET - Points to the DPDK target environment directory.

 

  make
    CC main.o
    LD helloworld
    INSTALL-APP helloworld
    INSTALL-MAP helloworld.map
  ls build/app
    helloworld helloworld.map

 

&& 运行helloworld
