Safe to use sampling driver on Linux with CONFIG_PERF enabled?

Hi,

Is it safe to load the sampling driver and use VTune Amplifier if the host kernel has the CONFIG_PERF options enabled? It seems that both driver and Linux perf will contend on the same hardware resources.

Is it safe provided that no one uses Linux "perf" while VTune is running?

Thanks

Yes. Both VTune Amplifier XE and Linux"perf" tooluse same PMU resource. However you can run perf when VTune Amplifier XE is not working, and you can run VTune Amplifier when perf is not working.

I have one machine with perf tool installed, but VTune works smoothly.

Regards, Peter
