How to Check the Firmware Version of Intel® QuickAssist Technology (Intel® QAT) Hardware in Linux*

• Unable to find the firmware version of the Intel® QAT 8960 card using standard commands.
• Need to verify the firmware version for compatibility purposes.

The Intel® QAT firmware version is exposed as part of the /sys/kernel/debug/qat* directory tree. The information of all Intel® QAT End-Points, including the firmware information, is available in this directory.

To check the current firmware version, run the following commands:

1. Run the command ll /sys/kernel/debug/qat* to display all the information for the Intel® QAT End-Points. You will see an output similar to the following:

   # ll /sys/kernel/debug/qat*
   '/sys/kernel/debug/qat_c6xx_0000:3f:00.0':
   total 0
   -r--------. 1 root root 0 Apr 20 18:29 cnv_errors
   -r--------. 1 root root 0 Apr 20 18:29 dev_cfg
   -r--------. 1 root root 0 Apr 20 18:29 frequency
   -r--------. 1 root root 0 Apr 20 18:29 fw_counters
   -r--------. 1 root root 0 Apr 20 18:29 heartbeat
   -r--------. 1 root root 0 Apr 20 18:29 heartbeat_failed
   -r--------. 1 root root 0 Apr 20 18:29 heartbeat_sent
   drwxr-xr-x. 18 root root 0 Apr 20 18:29 transport
   drwxr-xr-x. 2 root root 0 Apr 20 18:29 version

2. The version subdirectory includes the firmware version information. Run the following command to display it:

   # cat /sys/kernel/debug/qat_c6xx_0000\:3f\:00.0/version/fw
   4.2.0

The Intel® QAT driver package has to be installed in the system to properly display the Intel® QAT End-Points information. See Which Intel® QuickAssist Technology (Intel® QAT) Driver Should Be Used Based on the Platform?.
