2 # Generic thermal sysfs drivers configuration
6 tristate "Generic Thermal sysfs driver"
8 Generic Thermal Sysfs driver offers a generic mechanism for
9 thermal management. Usually it's made up of one or more thermal
10 zone and cooling device.
11 Each thermal zone contains its own temperature, trip points,
13 All platforms with ACPI thermal support can use this driver.
14 If you want this support, you should say Y or M here.

24 prompt "Default Thermal governor"
25 default THERMAL_DEFAULT_GOV_STEP_WISE
27 This option sets which thermal governor shall be loaded at
28 startup. If in doubt, select 'step_wise'.
30 config THERMAL_DEFAULT_GOV_STEP_WISE
32 select THERMAL_GOV_STEP_WISE
34 Use the step_wise governor as default. This throttles the
35 devices one step at a time.
37 config THERMAL_DEFAULT_GOV_FAIR_SHARE
39 select THERMAL_GOV_FAIR_SHARE
41 Use the fair_share governor as default. This throttles the
42 devices based on their 'contribution' to a zone. The
43 contribution should be provided through platform data.
45 config THERMAL_DEFAULT_GOV_USER_SPACE
47 select THERMAL_GOV_USER_SPACE
49 Select this if you want to let the user space manage the
54 config THERMAL_GOV_FAIR_SHARE
55 bool "Fair-share thermal governor"
57 Enable this to manage platform thermals using fair-share governor.
59 config THERMAL_GOV_STEP_WISE
60 bool "Step_wise thermal governor"
62 Enable this to manage platform thermals using a simple linear
64 config THERMAL_GOV_USER_SPACE
65 bool "User_space thermal governor"
67 Enable this to let the user space manage the platform thermals.
70 bool "generic cpu cooling support"
74 This implements the generic cpu cooling mechanism through frequency
75 reduction. An ACPI version of this already exists
76 (drivers/acpi/processor_thermal.c).
77 This will be useful for platforms using the generic thermal interface
78 and not the ACPI interface.
80 If you want this support, you should say Y here.
82 config THERMAL_EMULATION
83 bool "Thermal emulation mode support"
85 Enable this option to make a emul_temp sysfs node in thermal zone
86 directory to support temperature emulation. With emulation sysfs node,
87 user can manually input temperature and test the different trip
88 threshold behaviour for simulation purpose.
90 WARNING: Be careful while enabling this option on production systems,
91 because userland can easily disable the thermal policy by simply
92 flooding this sysfs node with low temperature values.
95 bool "SPEAr thermal sensor driver"
99 Enable this to plug the SPEAr thermal sensor driver into the Linux
103 tristate "Renesas R-Car thermal driver"
104 depends on ARCH_SHMOBILE
106 Enable this to plug the R-Car thermal sensor driver into the Linux
109 config KIRKWOOD_THERMAL
110 tristate "Temperature sensor on Marvell Kirkwood SoCs"
111 depends on ARCH_KIRKWOOD
114 Support for the Kirkwood thermal sensor driver into the Linux thermal
115 framework. Only kirkwood 88F6282 and 88F6283 have this sensor.
118 tristate "Temperature sensor on Marvell Dove SoCs"
122 Support for the Dove thermal sensor driver in the Linux thermal
125 config DB8500_THERMAL
126 bool "DB8500 thermal management"
127 depends on ARCH_U8500
130 Adds DB8500 thermal management implementation according to the thermal
131 management framework. A thermal zone with several trip points will be
132 created. Cooling devices can be bound to the trip points to cool this
133 thermal zone if trip points reached.
135 config ARMADA_THERMAL
136 tristate "Armada 370/XP thermal management"
137 depends on ARCH_MVEBU
140 Enable this option if you want to have support for thermal management
141 controller present in Armada 370 and Armada XP SoC.
143 config DB8500_CPUFREQ_COOLING
144 tristate "DB8500 cpufreq cooling"
145 depends on ARCH_U8500
146 depends on CPU_THERMAL
149 Adds DB8500 cpufreq cooling devices, and these cooling devices can be
150 bound to thermal zone trip points. When a trip point reached, the
151 bound cpufreq cooling device turns active to set CPU frequency low to
154 config INTEL_POWERCLAMP
155 tristate "Intel PowerClamp idle injection driver"
158 depends on CPU_SUP_INTEL
160 Enable this to enable Intel PowerClamp idle injection driver. This
161 enforce idle time which results in more package C-state residency. The
162 user interface is exposed via generic thermal framework.
164 config X86_PKG_TEMP_THERMAL
165 tristate "X86 package temperature thermal driver"
166 depends on X86_THERMAL_VECTOR
167 select THERMAL_GOV_USER_SPACE
170 Enable this to register CPU digital sensor for package temperature as
171 thermal zone. Each package will have its own thermal zone. There are
172 two trip points which can be set by user to get notifications via thermal
173 notification methods.
