Hi, Leland.
I don't know what plans VM development might have for supporting the
hardware CPU Measurement Facility, like z/OS does with HIS, but I get
the impression that the CPU MF is meant to be used mostly by IBM h/w
support to detect and diagnose performance issues in the new processors.
I don't think there are any z/OS performance setting knobs that you can
turn based on what the HIS reports, so it might not be all that
interesting to performance folks.

z/OS currently supports hardware instrumentation data collection on
z10 and z196 machines via z/OS's Hardware Instrumentation Facility
(HIS). In presentations at SHARE and zExpo, IBM seems to indicate
that HIS-like support is in the works for z/VM. Is HIS-like support
available yet for z/VM? If available, what APAR(s) provide this
support?
Thanks much,
Leland
