Adnreas,
perfmon2 doesn't work on Sossamans because it doesn't know about the cpu
model Sossaman is model 14.
I copied the "case" statements for model 13 which is supposed to be
Pentium-M and it seems to work.
Careful here, I don't know all the various Pentium models are their PMUs.
There is only support for Pentium M style PMU in libpfm and pfmon. If you know
for sure that your PMU model is like Pentium M, then it is safe to enabel
support
in libpfm and pfmon. Otherwise you may get garbage.
Quite honestly I had no idea which PMU is implemented in the Sossaman.
I assumed it to be the P-M PMU, but I was actually wrong... (although
the P-M counter seem to work)
The Dempsey (family 15, model 6) is also not handled properly, but I
couldn't check whether a simple copy of model 5 would work.
Do you have an Intel document that clearly describes the various models and
their
PMU support. I would expect more models to follow the Pentium 4/Xeon PMU rather
than the Pentium M PMU.
AFAIK (now), all the soon-to-come Core(2) will have an extended version
of the P4/Xeon PMU.
