Subject: having problem getting use of perforamance registers ... is my processor supported?
Hello,

I am trying to get oprofile running on Linux 2.6 (RedHat). Following is a 
cat of /proc/cpuinfo:

processor : 0

vendor_id : GenuineIntel

cpu family : 15

model : 4

model name : Intel(R) Pentium(R) D CPU 2.66GHz

stepping : 7

cpu MHz : 2666.576

cache size : 1024 KB

physical id : 0

siblings : 2

core id : 0

cpu cores : 2

fpu : yes

fpu_exception : yes

cpuid level : 5

wp : yes

flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat 
pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm syscall nx lm pni monitor 
ds_cpl tm2 cid cx16 xtpr

bogomips : 5342.17

clflush size : 64

cache_alignment : 128

address sizes : 36 bits physical, 48 bits virtual

power management:

processor : 1

You will note that "model" is 4. I noticed in arch/i386/oprofile/nmi_int.c 
that there is a check in function p4_init:

if (cpu_model > 3)

return 0;

Does this mean that my processor is not supported in Oprofile and if so why?

Regards, Bill
