Hi
I am getting this when trying to run pfmon. I downloaded the perfmon kernel
from GIT tree. I can successfully compile and install libpfm-3.10. I can
successfully run all the examples from examples_v2.x folder in libpfm.
However, pfmon fails to run with the error "No pmu detected type=41".
To check if my compilation and installation process is correct or not, I
repeated the whole process on an older IBM Thinkpad laptop (Intel Core Duo
T2400 processor) and can successfully run pfmon. However, I need to run
pfmon on the newer laptop.
I was going through the pfmon.c source code and I guess the error is thrown
by pfmon_detect() which calls pfm_get_pmu_type(&type).
Thanks
Saurabh
