Enabling the Device

The KAE ZIP device is used as an example.

1. Enable the driver.

   1 2	modprobe hisi_zip pf_q_num=32 modprobe hisi_migration

2. Query the BDF identifier of the ZIP device.

   1	lspci | grep ZIP

   

3. Verify the NUMA node where the ZIP device is located. (Optional)

   1	lspci -s 31:00.0 -v

   

   

   The performance is optimal if KAE passthrough devices in a VM are located on the same NUMA node.

4. Sets the VF.
