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) ?
Not exactly what you want but might be close:
git clone https://github.com/dsahern/linux
git checkout perf-full-monty
make -C tools/perf
perf sched record -ag -- sleep 1
perf sched timehist -S
shows the grains of sand (each sample) and then a runtime summary byt
task. Example report attached for box just running a few VMs.
