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.
20 depends on HWMON=y || HWMON=THERMAL
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.
117 config EXYNOS_THERMAL
118 tristate "Temperature sensor on Samsung EXYNOS"
119 depends on (ARCH_EXYNOS4 || ARCH_EXYNOS5)
120 depends on CPU_THERMAL
122 If you say yes here you get support for TMU (Thermal Management
123 Unit) on SAMSUNG EXYNOS series of SoC.
126 tristate "Temperature sensor on Marvell Dove SoCs"
130 Support for the Dove thermal sensor driver in the Linux thermal
133 config DB8500_THERMAL
134 bool "DB8500 thermal management"
135 depends on ARCH_U8500
138 Adds DB8500 thermal management implementation according to the thermal
139 management framework. A thermal zone with several trip points will be
140 created. Cooling devices can be bound to the trip points to cool this
141 thermal zone if trip points reached.
143 config ARMADA_THERMAL
144 tristate "Armada 370/XP thermal management"
145 depends on ARCH_MVEBU
148 Enable this option if you want to have support for thermal management
149 controller present in Armada 370 and Armada XP SoC.
151 config DB8500_CPUFREQ_COOLING
152 tristate "DB8500 cpufreq cooling"
153 depends on ARCH_U8500
154 depends on CPU_THERMAL
157 Adds DB8500 cpufreq cooling devices, and these cooling devices can be
158 bound to thermal zone trip points. When a trip point reached, the
159 bound cpufreq cooling device turns active to set CPU frequency low to
162 config INTEL_POWERCLAMP
163 tristate "Intel PowerClamp idle injection driver"
166 depends on CPU_SUP_INTEL
168 Enable this to enable Intel PowerClamp idle injection driver. This
169 enforce idle time which results in more package C-state residency. The
170 user interface is exposed via generic thermal framework.
172 config X86_PKG_TEMP_THERMAL
173 tristate "X86 package temperature thermal driver"
174 depends on X86_THERMAL_VECTOR
175 select THERMAL_GOV_USER_SPACE
178 Enable this to register CPU digital sensor for package temperature as
179 thermal zone. Each package will have its own thermal zone. There are
180 two trip points which can be set by user to get notifications via thermal
181 notification methods.
