This set introduces the required infrastructure to detect, report, and count errors in the QAT drivers and enables the reporting of errors in QAT GEN4 devices. In particular, it enables the reporting of correctable, nonfatal, and fatal errors. In addition, exposes the number of occurrences of each type of error through sysfs. The first patch adds the common infrastructures for error reporting for all generations of QAT. Patches from 2 to 5 and 7 enable the reporting of errors flagged through the register ERRSOUx for GEN4 devices. ERRSOUx error reporting for GEN4 devices. Patch 6 adds a helper to retrieve the base address of the aram bar. Patch 8 introduces the ras counter interface for counting QAT-specific errors, and exposes such counters through sysfs. Patch 9 adds logic to count correctable, nonfatal, and fatal errors for GEN4 devices.
