On the flip side "PFT" is the format of the output generated by the tracer. What is important to identify is the type of tracer fitted to the SoC, either "ETM" or "PTM". > > -- > 1.9.1 > -- To unsubscribe from this list: send the line "unsubscribe linux-arm-msm" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

I was unable to find PTM 1.1 in the ARM documentation and PFT v1.1 is supported only by PTM, if understand it correctly.
