John,

 

This does not seem to be an xenoprof problem, but a general oprofile error.

It seems you are not being able to write to oprofilefs for some reason.

You should see several files under /dev/oprofile after you execute any opcontrol command for the first time (e.g. opcontrol --reset).

Anyway, I suggest that you post your question to the oprofile mailing list (oprofile-list@xxxxxxxxxxxxxxxxxxxxx)

 

Regards

 

Renato

Hi.

For those who are new to xenoprof ( e.g. Todd), I have installed xenorpof patch from following website (please follow the instructions):
http://xenoprof.sourceforge.net/

For oprofile, I have downloaded from
http://oprofile.sourceforge.net/news/
I have used oprofile 0.9.2

Hi John,

I don't think you provided the list with enough information. How did you get to this point? What did you install etc.? For example I don't have a opcontrol file that I am aware of.

I don't have much experience with xenoprof either. Could you provide links or packages and a litlle more background into the problem?

Best Regards,
Todd

Hi,

Any help with following mail will be great. I am using oprofile 0.9.2. Also, when i run"opreport -l" I get segmentation fault. Running "opreport"  works correctly. Any help will be great. I am using fedora core.
