cpum_sf.96d859 Sampling facility support for perf is not available: reason=<reason code>
Explanation
The device driver could not initialize the sampling facility support.
Possible reason codes are:
0001: The device driver failed to query CPU-measurement sampling facility
information.
0002: The device driver does not support the basic-sampling function that
is available on the LPAR within which the Linux instance runs.
0003: The device driver could not register to receive CPU-measurement alerts.
A possible cause of this problem is memory constraints.
0004: The device driver could not register the Performance Measurement Unit
(PMU) for the CPU-measurement sampling facility.
A possible cause of this problem is memory constraints.
User response
Consider assigning more memory to your Linux instance.
