Configuring the BIOS

Enable the system memory management unit (SMMU) to allow VF passthrough (for enabling KAE) and NIC passthrough to the VM.

To enable SMMU, perform the following steps:

1. Restart the server and enter the BIOS.

   For details, see "Accessing the BIOS" in TaiShan Server BIOS Parameter Reference (Kunpeng 920 Processor).

2. Enable SMMU.
   

   Enable this option only in virtualization scenarios. In non-virtualization scenarios, disable it.

   In the BIOS, choose Advanced > MISC Config > Support Smmu and set this option to Enabled.

   Then, set Smmu Work Around to Enabled.

   

3. Press F10 to save the BIOS configuration and restart the server.
