# qat\_init(8)

QAT resource initializer qat\_init

## NAME

qat\_init - QAT resource initializer

**qat\_init**

## SYNOPSIS

**qat\_init**

## DESCRIPTION

**qat\_init** initializes the Intel© Quick Assist Technology (Intel© QAT) devices in preparation for use by the user space library (qatlib).

When run on a host system with physical function (PF) QAT devices visible and bound to the QAT device driver, the qat\_init script will enable sriov on each of the PF devices. This enables the virtual function (VF) devices.

For each of the QAT VF devices, the qat\_init binds the device to the vfio-pci device driver, making it available for applications using the qatlib user space library.

## ENVIRONMENT VARIABLES

**LKCF\_LIST** if set, gives a list of VF devices that should be used for accelerating operations from the Linux crypto framework instead of being available for user space applications.

Example:

```
LKCF_LIST="0000:3d:01.0 0000:3f:01.0 0000:da:01.0"
```
