1.1 What is an Operating Performance Point (OPP)?
|
||||
|
||||
Complex SoCs of today consists of a multiple sub-modules working in conjunction.
|
||||
In an operational system executing varied use cases, not all modules in the SoC
|
||||
need to function at their highest performing frequency all the time. To
|
||||
facilitate this, sub-modules in a SoC are grouped into domains, allowing some
|
||||
domains to run at lower voltage and frequency while other domains are loaded
|
||||
more. The set of discrete tuples consisting of frequency and voltage pairs that
|
||||
domains to run at lower voltage and frequency while other domains run at
|
||||
voltage/frequency pairs that are higher.
|
||||
|
||||
The set of discrete tuples consisting of frequency and voltage pairs that
|
||||
the device will support per domain are called Operating Performance Points or
|
||||
OPPs.
|
||||
|
||||
As an example:
|
||||
Let us consider an MPU device which supports the following:
|
||||
{300MHz at minimum voltage of 1V}, {800MHz at minimum voltage of 1.2V},
|
||||
{1GHz at minimum voltage of 1.3V}
|
||||
|
||||
We can represent these as three OPPs as the following {Hz, uV} tuples:
|
||||
{300000000, 1000000}
|
||||
{800000000, 1200000}
|
||||
{1000000000, 1300000}
|
||||
|
||||
1.2 Operating Performance Points Library
|
||||
|
||||
OPP library provides a set of helper functions to organize and query the OPP
|
||||
information. The library is located in drivers/base/power/opp.c and the header

is located in include/linux/opp.h. OPP library can be enabled by enabling
