Hello Lingchuan Meng,
Does your kernel have the perfmon2 patch set compiled into it? perfmon2
is not yet in the kernel.org kernel at this point nor in many distros, and
so you either need to patch your current kernel with the appropriate
perfmon2 patch set from here:

Are you using a kernel with perfmon support compiled in? I don't believe
pfmon will work by itself; you probably need to patch the kernel source,
recompile, and boot from it before you can do anything with either pfmon
or libpfm.
Good luck.

It seems you did not include perfmon2 which building your kernel.
Basically, once you have patched your kernel with perfmon2, then you
need to select perfmon2 to be built into your kernel using "make
menuconfig", and then build it. The pfmon error message should go away
once you boot into this kern
Hi all,
I'm new to Perfmon2. I am not able to start pfmon after installation.
The error message says:
"Cannot determine host kernel perfmon version, check /sys/kernel/perfmon"
There is no permon in /sys/kernel. I've googled around, and found that
a solution doesn't seem to have been discussed.
