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.
For further instructions refer to the Intel® QAT firmware page.
