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?
