Adreno Profiler GPU frequency clocks per/second

  Hi,

I'm trying to profile GPU usage during runtime. I had Adreno Profiler set up, opened a graph, dragged two graph metrics ("clock/second" and "% busy") to the graph, profiled for dozens of seconds, then exported the data to a csv file.

I thought the "clock/second" should be the Hz number of GPU frequency. However, in the "clock/second" column, I got Decimal  numbers  , which is absolutely not GPU frequency number.  The GPU freq should be available frequencies of system file /sys/devices/platform/kgsl-3d0.0/kgsl/kgsl-3d0/gpu_available_frequencies but I got  frequencies  which I cannot find in the system file.

Does anyone know what does that metric mean?

 

Thanks!

The clock/second shown is a calculated value obtained by counting the clocks and dividing by a measured time.  Thev value is a decimal value because of the division.  It will not match the available frequencies because it is basically an average over the time period.

If you could share the device and values that you see displayed in the profiler graph, we can comment further.
