Error: Direct Firmware Load Failed for Intel® QAT Device in Linux*

Unable to use the Intel® QAT device due to the following error:

Direct firmware load for qat_4xxx_mmp.bin failed with error -2

OR

Direct firmware load for qat_420xx_mmp.bin failed with error -2

Most of the latest operating systems should include the upstream binary files for the firmware of the Intel® QAT devices. However, sometimes the operating system may not include the files. In such a scenario, the firmware binary files must be installed manually to properly use the Intel® QAT devices. The required binary files are within the Intel® QAT package or upstream into kernel.org Linux* firmware.

1. Download the Intel® QAT package from the official Intel website: Intel® QuickAssist Technology (Intel® QAT) Driver for Linux* for Hardware Version 2.0
2. Extract the package to a directory on your system.
3. Locate the firmware binary files within the extracted package. The firmware binary files are located within the Intel® QAT package under the directory quickassist/qat/fw
4. Copy the binary files to the appropriate firmware directory on your Linux* system (for example, /lib/firmware/).
5. Reload the firmware using the appropriate system commands.
