[perfmon2] can't create perfmon context: Function not implemented

[Vishal G. <vi...@cc...>]

Hi,

I'm having problems getting perfmon to run. I get this error while 
running it:

root@host linux-2.6 # pfmon ls
detection of unavailable registers failed, leave it to the kernel to decide
can't create perfmon context: Function not implemented


Here is my setup:
1. Cloned kernel 2.6.30 from Stephane's git repository
2. Enable perform support in kernel, compiled, installed
3. Built and installed libpfm-3.10 (pfmon does not build with libpfm4 as 
it can't find perfmon.h)
4. Built and installed pfmon-3.9

I've ubuntu server 10.04 LTS running on an Intel core i7 processor. I'm 
getting the above mentioned error when I run pfmon. I'm stuck and I 
would really appreciate any help on this.

Thanks,
Vishal
