[PATCH v4 3/5] cpufreq: scpi: Register an Energy Model
From: Quentin Perret <hidden>
Date: 2019-02-04 11:10:24
Also in:
linux-pm, lkml
Subsystem:
cpu frequency scaling framework, system control & power/management interface (scpi/scmi) message protocol drivers, the rest · Maintainers:
"Rafael J. Wysocki", Viresh Kumar, Sudeep Holla, Linus Torvalds
Now that PM_OPP provides a helper function to estimate the power consumed by CPUs, make sure to try and register an Energy Model (EM) from scpi-cpufreq, hence ensuring interested subsystems (the task scheduler, for example) can make use of that information when available.
