The document tries to describe currently used interface between Linux kernel
8
+
and boot loaders on Samsung Exynos based boards. This is not a definition
9

of interface but rather a description of existing state, a reference
10
+
for information purpose only.
11

+
In the document "boot loader" means any of following: U-boot, proprietary
13

SBOOT or any other firmware for ARMv7 and ARMv8 initializing the board before
14

executing kernel.

In legacy mode the driver implements a scaling driver with an internal
10
-
governor for Intel Core processors. The driver follows the same model
11
-
as the Transmeta scaling driver (longrun.c) and implements the
12
-
setpolicy() instead of target(). Scaling drivers that implement
13
-
setpolicy() are assumed to implement internal governors by the cpufreq
14
-
core. All the logic for selecting the current P state is contained
15
-
within the driver; no external governor is used by the cpufreq core.
9
+
In legacy mode, the Intel P-state implements two internal governors,
10
+
performance and powersave, that differ from the general cpufreq governors of
11
+
the same name (the general cpufreq governors implement target(), whereas the
12
+
internal Intel P-state governors implement setpolicy()). The internal
13
+
performance governor sets the max_perf_pct and min_perf_pct to 100; that is,
14
+
the governor selects the highest available P state to maximize the performance
15
+
of the core. The internal powersave governor selects the appropriate P state
16
+
based on the current load on the CPU.
16
17
17
18
In HWP mode P state selection is implemented in the processor
18
19
itself. The driver provides the interfaces between the cpufreq core and
19
20
the processor to control P state selection based on user preferences
20
21
and reporting frequency to the cpufreq core. In this mode the
