Oprofile on ARM: cpu_type 'unset' is not valid

[Robert P. <rob...@we...>]

Hello!

I am trying to use Oprofile on an ARM-RealView PB1176 board (ARM11 
processor). When I try to initialize the daemon, I get:

opcontrol --init
cpu_type 'unset' is not valid
you should upgrade oprofile or force the use of timer mode

I use current userspace tools (0.9.5). It seems that the CPU is not 
correctly recognized by the kernel:

(dmesg)
oprofile: cpu_architecture() returns 0x9, using arm/11mpcore model

Kernel is 2.6.28. In the kernel-tree (arch/arm/include/asm/system.h), 
there is no CPU-Type defind for 0x9, so maybe it defaults to arm/11mpcore.


Any help would be appreciated!
