Re: [Xen-devel] Xenoprof: getting Oprofile out of timer mode?

Yeah, it looks the problem is the following check in
arch/x86/oprofile/nmi_int.c:
if (cpu_model > 4)

Intel processors 920 and 955 (perhaps others, you would have to ask
Intel)
appear to return 6 as the cpu model. Making the obvious change to the
above
gets oprofile out of timer only mode. An obvious patch is attached.
Presumably there is the same problem with oprofile on Linux running
natively (no Xen)?
