RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

This bug was initially created as a copy of Bug #2152191

I am copying this bug because: The same change should be made in RHEL9 to prevent the newer OS being out-of-date wrt to the older OS.



Description of problem:
   Customer is requesting pcm package rebased to at least version 202205 or newer to provide functionality for keeping NMI watchdog enabled with the 'PCM_KEEP_NMI_WATCHDOG=1' env variable.


Additional info:
   Customer has successfully tested with version 202210 in their environment.  

Customer reported experiencing issues in their environment during benchmark performance loads on specific hardware and hypervisor versions with vPMC enabled for guest and PCM utility running:  
    Kernel panic: 'Error: Uhhuh. NMI received for unknown reason <xx>'

After using v202210 from upstream and keeping NMI Watchdog enabled they were unable to reproduce this panic.
