2.7.2. 运行SR-IOV设计实例
按照以下步骤在硬件上测试SR-IOV设计实例:
- 浏览到设计实例目录下的./software/user/example。
- 运行以下命令,编译设计实例应用程序:
make
然后执行以下步骤:
- 运行以下命令以运行链路测试应用程序:
sudo ./intel_fpga_pcie_link_test
- 选择Option 1: Manually Select the Device
- 键入虚拟功能已分配Physical Function的BDF。
- 键入BAR 0开始测试菜单。

- 键入Option 7使能当前器件的SR-IOV。
- 键入当前器件中要被使能的虚拟功能的编号16。

- 键入Option 8执行对物理功能内每个已分配并已使能的虚拟功能的链路测试。链路测试应用程序以每个数据的单个dword执行100次存储器写然后读回数据。测试结束时,应用程序打印测试中失败的虚拟功能的编号。

- 推出应用并运行命令
lspci -d 1172: | grep -c Altera
以验证PFs和VFs枚举。预期结果是PFs和VFs的和。
为避免仅使能一个物理功能的16 VFs,您应该已经看到报告的18个器件,PF0的2个PFs + 16个VFs。您还可以对设计实例中包含的第二个功能重复同样的处理,这样就将看到总共报告34个器件,2个PFs + 32个VFs。
[root@localhost ~]# lspci -d 1172: | grep -c Altera
- 运行以下命令以运行链路测试应用程序:
