opreport isn't showing processes

[Matt H. <mwh...@gm...>]

Hi all,

I've checked out oprofile from CVS, and built for an XScale (ARM)
processor using a kernel based on 2.6.12.

The daemon starts ok:

  / # opcontrol --vmlinux=/home/me/vmlinux-2.6.12.eabi
  / # opcontrol --start
  Using 2.6+ OProfile kernel interface

Then, I ran some Gtk+ user interface processes on the system. Later,
opreport doesn't seem to know anything about the activity which
happened outside the kernel:

  / # opreport -l
  CPU: CPU with timer interrupt, speed 0 MHz (estimated)
  Profiling through timer interrupt
            TIMER:0|
    samples|      %|
  ------------------
    7205014 99.4734 no-vmlinux
      38144  0.5266 vmlinux-2.6.12.eabi

Have I missed a step to enable mapping of CPU cycles back to the
user-space processes? Alternately, the estimate of 0 MHz makes me
wonder whether there's low-level trouble with support for this CPU.

Thanks,

Matt
