This bug is awaiting verification that the linux-azure- fips/6.8.0-1042.48+fips1 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-noble-linux-azure-fips' to 'verification-done-noble-linux-azure-fips'. If the problem still exists, change the tag 'verification-needed-noble-linux-azure-fips' to 'verification-failed-noble-linux-azure-fips'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

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. Update 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. For Ubuntu 24.04, the following kernel patches are required: 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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/2121956/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
