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.
90 bool "SPEAr thermal sensor driver"
94 Enable this to plug the SPEAr thermal sensor driver into the Linux
98 tristate "Renesas R-Car thermal driver"
99 depends on ARCH_SHMOBILE
101 Enable this to plug the R-Car thermal sensor driver into the Linux
104 config KIRKWOOD_THERMAL
105 tristate "Temperature sensor on Marvell Kirkwood SoCs"
106 depends on ARCH_KIRKWOOD
109 Support for the Kirkwood thermal sensor driver into the Linux thermal
110 framework. Only kirkwood 88F6282 and 88F6283 have this sensor.
112 config EXYNOS_THERMAL
113 tristate "Temperature sensor on Samsung EXYNOS"
114 depends on (ARCH_EXYNOS4 || ARCH_EXYNOS5)
115 depends on CPU_THERMAL
117 If you say yes here you get support for TMU (Thermal Management
118 Unit) on SAMSUNG EXYNOS series of SoC.
120 config EXYNOS_THERMAL_EMUL
121 bool "EXYNOS TMU emulation mode support"
122 depends on EXYNOS_THERMAL
124 Exynos 4412 and 4414 and 5 series has emulation mode on TMU.
125 Enable this option will be make sysfs node in exynos thermal platform
126 device directory to support emulation mode. With emulation mode sysfs
127 node, you can manually input temperature to TMU for simulation purpose.
130 tristate "Temperature sensor on Marvell Dove SoCs"
134 Support for the Dove thermal sensor driver in the Linux thermal
137 config DB8500_THERMAL
138 bool "DB8500 thermal management"
139 depends on ARCH_U8500
142 Adds DB8500 thermal management implementation according to the thermal
143 management framework. A thermal zone with several trip points will be
144 created. Cooling devices can be bound to the trip points to cool this
145 thermal zone if trip points reached.
147 config DB8500_CPUFREQ_COOLING
148 tristate "DB8500 cpufreq cooling"
149 depends on ARCH_U8500
150 depends on CPU_THERMAL
153 Adds DB8500 cpufreq cooling devices, and these cooling devices can be
154 bound to thermal zone trip points. When a trip point reached, the
155 bound cpufreq cooling device turns active to set CPU frequency low to
158 config INTEL_POWERCLAMP
159 tristate "Intel PowerClamp idle injection driver"
162 depends on CPU_SUP_INTEL
164 Enable this to enable Intel PowerClamp idle injection driver. This
165 enforce idle time which results in more package C-state residency. The
166 user interface is exposed via generic thermal framework.
