OProfile falls back to timer mode profiling if platform does not support =
HW performance counters(ARM9).=20
Is there any other way or any other modules of ARM9 core which we can =
use to get profiling results better than timer mode.

I have made OProfile work with ARM11 performance counters, I don't
know what's needed for ARM9.
It seems to me that there is support on the kernel for ARM9
oprofiling, but I'm not sure on the userspace tools.
For ARM11 I had to patch OProfile like this:
Also it seems there's support on OProfile (userspace) for XScale1 and 2.
I'm new to the embedded world, so I don't know if xscale1,2 falls into ARM6.
Maybe asking in linux-arm-kernel would provide more insight.
