This is family15h which should have already supported in the
2.6.34 kernel w/ the OProfile-0.9.8. Could you please provide the
output from "dmesg"?

I built the 22.214.171.124 kernel and selected OProfile support when
I configured the kernel:
# CONFIG_OPROFILE_EVENT_MULTIPLEX is not set
I also built oprofile-0.9.8 using --with-kernel to point to
the kernel's source tree. I had to make a symlink to
asm->asm_generic in the kernel's include dir. I also had to
remove references to PERF_RECORD_MISC_GUEST_KERNEL and to
PERF_RECORD_MISC_GUEST_USER in libperf_events/operf_utils.cpp
since these aren't in 2.6.34.

I'm not sure why operf says my kernel's perf_events doesn't
support my processor type (AMD Opteron 6220). Is it true that
I can't use operf on this kernel/architecture? What I am
