Description Kevin Myers 2022-12-09 16:55:29 UTC

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.
