perfmon Itanium 9100 series support (Montvale)

perfmon Itanium 9100 series support (Montvale)

[Stephane Eranian]

Hello everyone,

Intel released the Itanium 9100 series (Montvale) a few days ago.

My understanding is that the Montvale PMU is fully compatible with
the Montecito PMU (dual-core Itanium 9000 series). Thus, there will
not be any patches needed neither at the kernel level, nor in libpfm
or pfmon to support this new processor.

Those comments hold true for the mainline perfmon (v2.0) and
the development perfmon in GIT (v2.7).

Thanks.

Perfmon prints out "Montecito PMU" when booted on a Montvale.
Updating the message may avoid some confusion.

Both Montvale and Montecito are family 32.  Montvale is model 1.
Montecito is model 0.

Yes, because it prints the PMU model not the processor model.
On Madison, it prints Itanium 2.
