Technical Tip: How to check supported QAT VF drivers for FortiGate VMs

Description

This article describes how to check supported QAT VF drivers. QAT refers to Intel® QuickAssist Technology (Intel® QAT).

Scope

FortiGate VMs hosted on a virtualization platform with Intel XEON CPU and QAT support.

Solution

To check which drivers are supported for a particular system, run the following command:

fnsysctl ls -l /sys/module

In the output, search for 'qat_'. For example, with a LAB KVM and a Virtual FortiGate, the output is as follows:

Note: A standard Linux grep command does not work for outputs of the fnsysctl command.

The supported drivers are:

• qat_c3xxxvf

• qat_c62xvf

• qat_d15xxvf

• qat_dh895xccvf

Refer to the appropriate Intel vendor documentation for verified QAT hardware support, hypervisor releases, and required driver modules.
