Android/Linux application profiling.

Dear all,

I want to dynamically profile Android/Linux user-space (and even better kernel space) applications for certain events. More specifically, I want to use the ARM hardware performance counters for collecting events such as branch mispredictions, cache hit misses, speculatively executed instructions etc..Please suggest me the best tool to use (gperf, Lttng etc...) ? Please share your experience.

Thanks so much.
