Re: Decoding the PTM traces

Hello,

I m trying to capture and decode PTM trace from Cortex A9 dual core.

I m successful in configuring the driver(arch/arm/kernel/etm.c) and setting the funnel to get data in ETB. But I don't know how to decode these traces.

Anyone has any pointers?

Thanks, Arun

I attached some tools I use to decode the traces. I have used this on the A8, A9 and A15. I assume since you cc-ed me you have already applied the kernel patches I posted a while back. Without them you will not get useful trace data from a dual core processor.
