time spent in function, including all callees

Hi,

Can I use opreport --callgraph to tell me what proportion of run time
was spent either in function foo(), or in any function called by foo()
? In other words I want to know the proportion of all samples with
stack trace info, where foo was found anywhere in the stack trace.

It seems to me that this information is present in the sample files,
but I can't work out how to extract it from the output of opreport
--callgraph.

Thanks,
Jay.

Yes, that information is certainly present in the callgraph report.  The non-indented lines show the total
samples and their percentage relative to total samples.  See
http://oprofile.sourceforge.net/doc/opreport.html#opreport-callgraph for more help on
interpreting callgraph reports.

The non-indented lines show the number/percentage of samples taken in
that function itself, representing the time spent in the function
itself, *excluding* time spent in the function's callees.

I want to see the time spent in the function *including* time spent in
any callees.

Thanks,
Jay.

I take it you mean "time spent in the callchain".  And since opreport shows only 
direct callers and callees for a given function, you'd have to chase around the 
report to manually gather the information you want.  It's possible there's a GUI 
available that might provide the callchain roll-up you're looking for -- or at 
least would make it easier to gather up.  I added Richard Purdie to cc since 
he's involved with OProfileUI (http://labs.o-hand.com/oprofileui/).  There's 
also an oprofile eclipse plug-in 
(http://www.eclipse.org/linuxtools/projectPages/oprofile/).   I've not had a 
chance to check it out before, and, unfortnately, I wasn't able to get this to 
install when I tried this morning.  Don't know if that plug-in supports 
callgraph either.

Summary: Patch to move from QT3 to QT4[qt3support] 

Initial Comment:
It seems that QT3 is outdated and some distributions (like Gentoo) have phased out support for it.  With the
attached patch the GUI tool is moved to rely on Qt4 by using the qt3 support library. I haven't tested it
much, I'm not a Qt expert and there are warnings about not connected signals, although the buttons seem to
work like with the QT3 version (i.e. sampling starts stops and the data can be flushed, and the flags selected).

Any plans to move Oprofile userspace from CVS to Git?

I was just wondering if there were any plans to move the Oprofile 
userspace from CVS to Git?  Or some other nicer version control system.

Thanks,
John

Feng,

this version looks very old, please update to 0.9.6.

Have you tried the latest upstream kernel (v2.6.37-rc1)?
