Hi, We're interested to know the CPU load/usage on our ARMv7 embedded system when running some use cases (e.g. simple video decode, double video decode, etc.). By CPU load, I mean a way to measure the time when the system was doing something else than Idle.
I've tried to get it from the performance counter statistics but couldn't find a way to get it, do I miss something ? Also tried to use perf for profiling the system (e.g. perf record -a). It report very useful percentage for the running processes that we exploit to detect hot spots. But It reports X% of the used CPU (nothing related to Idle or "rest of CPU"). So, any way with perf to get this information (directly or indirectly with few calculation) ?
