%c%How RAPL Works
|
||
|
|
|
||
|
|
* RAPL is not an analog power meter
|
||
|
|
|
||
|
|
* RAPL uses a software power model,
|
||
|
|
running on a helper controller
|
||
|
|
on the main chip package
|
||
|
|
|
||
|
|
* Energy is estimated using various
|
||
|
|
hardware performance counters,
|
||
|
|
temperature, leakage models and I/O
|
||
|
|
|
||
|
|
* The model is used for CPU throttling
|
||
|
|
and turbo-boost, but the values are
|
||
|
|
also exposed to users via a
|
||
|
|
model-specific register (MSR)
|
