** Description changed: + [ Impact ] + + Extend the s390 PAI monitoring infrastructure to cover new hardware capabilities in IBM Z systems. + Add sysfs and perf event names for counters introduced with Message Security Assist (MSA) 10 and 11, enabling monitoring of new AES-XTS and HMAC-SHA variants, as well as protected key operations. + Updates the NNPA counter set, adding events for modern AI/ML primitives. + + [ Fix ] + + Backport the following commits from upstream: + - d414f4ecb240b s390/pai: export number of sysfs attribute files + - 4ae48555d0edc s390/pai_crypto: Add support for MSA 10 and 11 pai counters + - 0114009953c11 s390/pai_ext: Update PAI extension 1 counters + + [ Test Plan ] + + Run an ubuntu instance on IBM Z hardware that actually supports MSA 10/11 and the updated NNPA instructions. + Check under /sys/bus/event_source/devices/pai_crypto/events/ and /sys/bus/event_source/devices/pai_ext/events/ to confirm that the new counters are exported. + + [ Regression Potential ] + + The regression potential of these patches is very low, + since they only extend the PAI crypto and extension event description tables + with new counters for newer IBM Z hardware generations. + Any possible issues would be limited to inaccurate labeling + or unsupported counters being exposed on systems with recent MSA or NNPA facilities, + with no effect on older IBM Z machines or other architectures. + + --- + Description: Processor Activity Instrumentation / Neural Network Processing Assist counters for new IBM z17 hardware.
