Is oprofile still working?
Hi all,
Is anyone using oprofile?
I'm getting segfaults from opreport at the moment, and I'm not sure if
it is opreport, or just me.
In case it is something just plain daft I am doing, here is how it goes:
opcontrol --reset
opcontrol --setup --no-vmlinux
opcontrol --start
... now I run my program, /tmp/myprog ...
opcontrol --dump
opcontrol --shutdown
then I run,
opreport -l

Renato,
When I tried running "opcontrol --start" (after previously running
"opcontrol --start-daemon") in dom0, I get this error message:

and this message in the Xen console:

FW: oprofile 0.9.3 xen symbols incorrect
Hi
I am using oprofile 0.9.3 on xen cs 16540 on an Intel system.
When I look at the top "hot" functions, I see p2m_change_type being one
of the top function in xen-syms. This function is only in the svm (AMD)
code and should not appear on an Intel system. I see that this function
is not being clled at all when I am running my apps as I have put printk
in the functions and they do

[LLVMdev] oprofile support?
I've been trying to get oprofile results for jitted code without success. I
built an 3.5.0 llvm with oprofile enabled, and tested it with lli on a
small test case. I built the latest oprofile from the git repository.
Debugging I can see that lli is registering the listener and making the
oprofile calls to the libopagent api to specify the names and address
ranges of jit'd routines, and

[LLVMdev] oprofile support?
Mi Maurice,
A follow up to Andy's comments: MCJIT can find line numbers for ELF files,
at least in limited circumstances. I know because I broke the regression
test for it while doing some cleanup recently. ;)
Looking at lib/ExecutionEngine/OProfileJIT/OProfileJITEventListener.cpp, I
see the line:
// TODO: support line number info (similar to IntelJITEventListener.cpp)

oprofile problem in centos with custom kernel
Hi!
I am trying to profile my custom 2.6.37 linux kernel with

the following problem.
(Before everyone starts shouting, I know that custom kernels are not
supported by centos team, however I really
need to run a modified version, due to a project concerning my MSc
thesis. So i hope for your understanding :-) .

Can someone please verify the steps to get a oprofile session profile

xenoprof patch for oprofile-0.9.7
I am rebasing Fedora rawhide oprofile package to oprofile-0.9.7. The xenoprof patches on http://xenoprof.sourceforge.net/#download look a bit dated. The newest version is for oprofile-0.9.5.
I massaged the patch oprofile-0.9.5-xen.patch to apply to oprofile-.0.9.7. Attached is that updated patch. Does this look reasonable? Is there a desire to get this into upstream oprofile? Or should the

Xenoprof (0.9.5) in PVOPS
Hi All.
I''m trying to use xenoprof in my Xeon machine with PVOPS (3.1.0 kernel) &
xen 4.1.1.
In the past, I had failed to use the xenoprof in this environment. (1 year
ago)
While baremetal booting shows the counter object in /dev/oprofile/0 (or
1,2,3) ,
booting with xen fails to create those objects.
Of course, opcontrol command doesn''t work. It only prints

OProfile on Dom0. Problem with starting daemon
Dear experts,
to monitor performance of applications on our private clouds I decided
to use Xenoprof. For that, I installed patched OProfile 0.9.5 on Dom0
and DomU. Then, I started the daemon on Dom0
opcontrol --start-daemon --active-domains=1 --separate=library
--event=LLC_MISSES:90000
and received the following error:
