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 tristate "generic cpu cooling support"
74 This implements the generic cpu cooling mechanism through frequency
75 reduction, cpu hotplug and any other ways of reducing temperature. An
76 ACPI version of this already exists(drivers/acpi/processor_thermal.c).
77 This will be useful for platforms using the generic thermal interface
78 and not the ACPI interface.
79 If you want this support, you should say Y here.
81 config THERMAL_EMULATION
82 bool "Thermal emulation mode support"
84 Enable this option to make a emul_temp sysfs node in thermal zone
85 directory to support temperature emulation. With emulation sysfs node,
86 user can manually input temperature and test the different trip
87 threshold behaviour for simulation purpose.
89 WARNING: Be careful while enabling this option on production systems,
90 because userland can easily disable the thermal policy by simply
91 flooding this sysfs node with low temperature values.
94 bool "SPEAr thermal sensor driver"
98 Enable this to plug the SPEAr thermal sensor driver into the Linux
102 tristate "Renesas R-Car thermal driver"
103 depends on ARCH_SHMOBILE
105 Enable this to plug the R-Car thermal sensor driver into the Linux
108 config KIRKWOOD_THERMAL
109 tristate "Temperature sensor on Marvell Kirkwood SoCs"
110 depends on ARCH_KIRKWOOD
113 Support for the Kirkwood thermal sensor driver into the Linux thermal
114 framework. Only kirkwood 88F6282 and 88F6283 have this sensor.
116 config EXYNOS_THERMAL
117 tristate "Temperature sensor on Samsung EXYNOS"
118 depends on (ARCH_EXYNOS4 || ARCH_EXYNOS5)
119 depends on CPU_THERMAL
121 If you say yes here you get support for TMU (Thermal Management
122 Unit) on SAMSUNG EXYNOS series of SoC.
125 tristate "Temperature sensor on Marvell Dove SoCs"
129 Support for the Dove thermal sensor driver in the Linux thermal
132 config DB8500_THERMAL
133 bool "DB8500 thermal management"
134 depends on ARCH_U8500
137 Adds DB8500 thermal management implementation according to the thermal
138 management framework. A thermal zone with several trip points will be
139 created. Cooling devices can be bound to the trip points to cool this
140 thermal zone if trip points reached.
142 config ARMADA_THERMAL
143 tristate "Armada 370/XP thermal management"
144 depends on ARCH_MVEBU
147 Enable this option if you want to have support for thermal management
148 controller present in Armada 370 and Armada XP SoC.
150 config DB8500_CPUFREQ_COOLING
151 tristate "DB8500 cpufreq cooling"
152 depends on ARCH_U8500
153 depends on CPU_THERMAL
156 Adds DB8500 cpufreq cooling devices, and these cooling devices can be
157 bound to thermal zone trip points. When a trip point reached, the
158 bound cpufreq cooling device turns active to set CPU frequency low to
161 config INTEL_POWERCLAMP
162 tristate "Intel PowerClamp idle injection driver"
165 depends on CPU_SUP_INTEL
167 Enable this to enable Intel PowerClamp idle injection driver. This
168 enforce idle time which results in more package C-state residency. The
169 user interface is exposed via generic thermal framework.
