This set introduces support for the QAT heartbeat feature. It allows detection whenever device firmware or acceleration unit will hang. We're adding this feature to allow our clients having a tool with they could verify if all of the Quick Assist hardware resources are healthy and operational. QAT device firmware periodically writes counters to a specified physical memory location. A pair of counters per thread is incremented at the start and end of the main processing loop within the firmware. Checking for Heartbeat consists of checking the validity of the pair of counter values for each thread. Stagnant counters indicate a firmware hang. The first patch removes historical and never used HB definitions. Patch no. 2 is implementing the hardware clock frequency measuring interface. The third introduces the main heartbeat implementation with the debugfs interface. The last patch implements an algorithm that allows the code to detect which version of heartbeat API is used at the currently loaded firmware.
