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 t...

It is time, I suppose then, to dust off the debugger; I was hoping one of you could point me in the correct direction to begin troubleshooting this.)

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
