 Could you please send me the commands you are using
 to run oprofile?

Sure, I use:

opcontrol --vmlinux=/boot/vmlinux-`uname -r` --xen=/boot/xen-unstable-syms
opcontrol --init

opcontrol --start


opcontrol --stop

opreport -l

**I changed opcontrol to echo XENIMAGE and XEN_RANGE to ~/.oprofile/daemonrc so they are picked up by oprofiled.

oprofiled cmd line looks like:

oprofiled --separate-lib=0 --separate-kernel=0 --spearate-thread=0 --separate-thread=0 --spearate-cpu=0 --events=GLOBAL_POWER_EVENTS:29:0:100000:1:1:1, --vmlinux=/boot/2.6.11-xen0-up --kernel-range=c01000000,c03ed2ae --xen-image=/boot/xen-unstable-syms --xen-range=c01000000,c03fc45e

This is weird. Something seems wrong. I am not familiar with the benchmark you are
 running. Is this something easy to try?
 If you could send me the code and some instructions on
 how to use it, I can try running the same benchmark
 in my environment.
 I will also spend sometime looking more carefully
 at xenoprof and my tests to see if I find anything wrong

 I have attached patches for enabling system wide profiling
 using oprofile for xen unstable.
 The patches were generated against change-set 1.1507 (May 22).
 The 4 attached files are

 1) xenoprof.txt:
         - xenoprof overview and user guide
 2) xenoprof-1.1-xen-3.0-devel.patch:
      - patch for xen
 3) xenoprof-1.1-linux-2.6.11:
      - patch for linux. Note that this needs to be applied
        twice, once to linux-2.6.11-xen0 and once to
        linux-2.6.11-xenU. (This is different than the last
        patch which was created against the linux sparse tree).
 4) xenoprof-1.1-oprofile-0.8.2:
      - patch for oprofile version 0.8.2
Thanks very much for these; this is going to be extremly
helpful. I am using these on xen-unstable-bk-1.1518 currently. One problem: so far I have not observed any ticks in xen-syms. I have tried SDET benchmark, which on your previous patches (for xen-2.0-testing), I would get about 12% of ticks in xen-syms.

This is on a single cpu xen0 domain with no other domains
running. I verified that the XENIMAGE and XEN_RANGE were getting passed to oprofiled correctly. I do not specify any active or
passive domains
since this is the only domain running. Any ideas why I would not get any ticks for xen-syms?

Has anyone else tried xenoprofile?
