In addition to this PDC patch, there are a few drivers with FTRACE
support coming for up QCOM SoCs. Would it make sense to open up a new
sub-folder for SoC specific FTRACE like say,
trace/events/soc/
trace/events/soc/qcom/

What would be your recommendation?

At the very least, I am thinking of renaming this file to
trace/events/qcom-pdc.h.

Thanks,
Lina
