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 prompt "Expose thermal sensors as hwmon device"
21 depends on HWMON=y || HWMON=THERMAL
24 In case a sensor is registered with the thermal
25 framework, this option will also register it
26 as a hwmon. The sensor will then have the common
27 hwmon sysfs interface.
29 Say 'Y' here if you want all thermal sensors to
30 have hwmon sysfs interface too.
34 prompt "APIs to parse thermal data out of device tree"
38 This options provides helpers to add the support to
39 read and parse thermal data definitions out of the
42 Say 'Y' here if you need to build thermal infrastructure
46 prompt "Default Thermal governor"
47 default THERMAL_DEFAULT_GOV_STEP_WISE
49 This option sets which thermal governor shall be loaded at
50 startup. If in doubt, select 'step_wise'.
52 config THERMAL_DEFAULT_GOV_STEP_WISE
54 select THERMAL_GOV_STEP_WISE
56 Use the step_wise governor as default. This throttles the
57 devices one step at a time.
59 config THERMAL_DEFAULT_GOV_FAIR_SHARE
61 select THERMAL_GOV_FAIR_SHARE
63 Use the fair_share governor as default. This throttles the
64 devices based on their 'contribution' to a zone. The
65 contribution should be provided through platform data.
67 config THERMAL_DEFAULT_GOV_USER_SPACE
69 select THERMAL_GOV_USER_SPACE
71 Select this if you want to let the user space manage the
76 config THERMAL_GOV_FAIR_SHARE
77 bool "Fair-share thermal governor"
79 Enable this to manage platform thermals using fair-share governor.
81 config THERMAL_GOV_STEP_WISE
82 bool "Step_wise thermal governor"
84 Enable this to manage platform thermals using a simple linear
86 config THERMAL_GOV_USER_SPACE
87 bool "User_space thermal governor"
89 Enable this to let the user space manage the platform thermals.
92 bool "generic cpu cooling support"
97 This implements the generic cpu cooling mechanism through frequency
98 reduction. An ACPI version of this already exists
99 (drivers/acpi/processor_thermal.c).
100 This will be useful for platforms using the generic thermal interface
101 and not the ACPI interface.
103 If you want this support, you should say Y here.
105 config THERMAL_EMULATION
106 bool "Thermal emulation mode support"
108 Enable this option to make a emul_temp sysfs node in thermal zone
109 directory to support temperature emulation. With emulation sysfs node,
110 user can manually input temperature and test the different trip
111 threshold behaviour for simulation purpose.
113 WARNING: Be careful while enabling this option on production systems,
114 because userland can easily disable the thermal policy by simply
115 flooding this sysfs node with low temperature values.
118 bool "SPEAr thermal sensor driver"
119 depends on PLAT_SPEAR
122 Enable this to plug the SPEAr thermal sensor driver into the Linux
126 tristate "Renesas R-Car thermal driver"
127 depends on ARCH_SHMOBILE
129 Enable this to plug the R-Car thermal sensor driver into the Linux
132 config KIRKWOOD_THERMAL
133 tristate "Temperature sensor on Marvell Kirkwood SoCs"
134 depends on ARCH_KIRKWOOD
137 Support for the Kirkwood thermal sensor driver into the Linux thermal
138 framework. Only kirkwood 88F6282 and 88F6283 have this sensor.
140 config EXYNOS_THERMAL
141 tristate "Temperature sensor on Samsung EXYNOS"
142 depends on (ARCH_EXYNOS4 || ARCH_EXYNOS5)
143 depends on CPU_THERMAL
145 If you say yes here you get support for TMU (Thermal Management
146 Unit) on SAMSUNG EXYNOS series of SoC.
149 tristate "Temperature sensor on Marvell Dove SoCs"
153 Support for the Dove thermal sensor driver in the Linux thermal
156 config DB8500_THERMAL
157 bool "DB8500 thermal management"
158 depends on ARCH_U8500
161 Adds DB8500 thermal management implementation according to the thermal
162 management framework. A thermal zone with several trip points will be
163 created. Cooling devices can be bound to the trip points to cool this
164 thermal zone if trip points reached.
166 config ARMADA_THERMAL
167 tristate "Armada 370/XP thermal management"
168 depends on ARCH_MVEBU
171 Enable this option if you want to have support for thermal management
172 controller present in Armada 370 and Armada XP SoC.
174 config DB8500_CPUFREQ_COOLING
175 tristate "DB8500 cpufreq cooling"
176 depends on ARCH_U8500
177 depends on CPU_THERMAL
180 Adds DB8500 cpufreq cooling devices, and these cooling devices can be
181 bound to thermal zone trip points. When a trip point reached, the
182 bound cpufreq cooling device turns active to set CPU frequency low to
185 config INTEL_POWERCLAMP
186 tristate "Intel PowerClamp idle injection driver"
189 depends on CPU_SUP_INTEL
191 Enable this to enable Intel PowerClamp idle injection driver. This
192 enforce idle time which results in more package C-state residency. The
193 user interface is exposed via generic thermal framework.
