Interface between kernel and boot loaders on Exynos boards
==========================================================
Author: Krzysztof Kozlowski
Date : 6 June 2015
The document tries to describe currently used interface between Linux kernel
and boot loaders on Samsung Exynos based boards. This is not a definition
of interface but rather a description of existing state, a reference
for information purpose only.
In the document "boot loader" means any of following: U-boot, proprietary
SBOOT or any other firmware for ARMv7 and ARMv8 initializing the board before
executing kernel.

Most cpufreq drivers (except the intel_pstate and longrun) or even most
cpu frequency scaling algorithms only offer the CPU to be set to one
frequency. In order to offer dynamic frequency scaling, the cpufreq
core must be able to tell these drivers of a "target frequency". So

@ -3,24 +3,25 @@ Intel P-state driver
This driver provides an interface to control the P state selection for
SandyBridge+ Intel processors. The driver can operate two different
modes based on the processor model legacy and Hardware P state (HWP)
modes based on the processor model, legacy mode and Hardware P state (HWP)
mode.
In legacy mode the driver implements a scaling driver with an internal
governor for Intel Core processors. The driver follows the same model
as the Transmeta scaling driver (longrun.c) and implements the
setpolicy() instead of target(). Scaling drivers that implement
setpolicy() are assumed to implement internal governors by the cpufreq
core. All the logic for selecting the current P state is contained
within the driver; no external governor is used by the cpufreq core.
In legacy mode, the Intel P-state implements two internal governors,
performance and powersave, that differ from the general cpufreq governors of
the same name (the general cpufreq governors implement target(), whereas the
internal Intel P-state governors implement setpolicy()). The internal
performance governor sets the max_perf_pct and min_perf_pct to 100; that is,
the governor selects the highest available P state to maximize the performance
of the core. The internal powersave governor selects the appropriate P state
based on the current load on the CPU.
In HWP mode P state selection is implemented in the processor
itself. The driver provides the interfaces between the cpufreq core and
the processor to control P state selection based on user preferences
and reporting frequency to the cpufreq core. In this mode the
internal governor code is disabled.
internal Intel P-state governor code is disabled.
In addtion to the interfaces provided by the cpufreq core for
In addition to the interfaces provided by the cpufreq core for
controlling frequency the driver provides sysfs files for
controlling P state selection. These files have been added to
/sys/devices/system/cpu/intel_pstate/
