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.
33 prompt "Default Thermal governor"
34 default THERMAL_DEFAULT_GOV_STEP_WISE
36 This option sets which thermal governor shall be loaded at
37 startup. If in doubt, select 'step_wise'.
39 config THERMAL_DEFAULT_GOV_STEP_WISE
41 select THERMAL_GOV_STEP_WISE
43 Use the step_wise governor as default. This throttles the
44 devices one step at a time.
46 config THERMAL_DEFAULT_GOV_FAIR_SHARE
48 select THERMAL_GOV_FAIR_SHARE
50 Use the fair_share governor as default. This throttles the
51 devices based on their 'contribution' to a zone. The
52 contribution should be provided through platform data.
54 config THERMAL_DEFAULT_GOV_USER_SPACE
56 select THERMAL_GOV_USER_SPACE
58 Select this if you want to let the user space manage the
63 config THERMAL_GOV_FAIR_SHARE
64 bool "Fair-share thermal governor"
66 Enable this to manage platform thermals using fair-share governor.
68 config THERMAL_GOV_STEP_WISE
69 bool "Step_wise thermal governor"
71 Enable this to manage platform thermals using a simple linear
73 config THERMAL_GOV_USER_SPACE
74 bool "User_space thermal governor"
76 Enable this to let the user space manage the platform thermals.
79 bool "generic cpu cooling support"
82 This implements the generic cpu cooling mechanism through frequency
83 reduction. An ACPI version of this already exists
84 (drivers/acpi/processor_thermal.c).
85 This will be useful for platforms using the generic thermal interface
86 and not the ACPI interface.
88 If you want this support, you should say Y here.
90 config THERMAL_EMULATION
91 bool "Thermal emulation mode support"
93 Enable this option to make a emul_temp sysfs node in thermal zone
94 directory to support temperature emulation. With emulation sysfs node,
95 user can manually input temperature and test the different trip
96 threshold behaviour for simulation purpose.
98 WARNING: Be careful while enabling this option on production systems,
99 because userland can easily disable the thermal policy by simply
100 flooding this sysfs node with low temperature values.
103 tristate "Temperature sensor driver for Freescale i.MX SoCs"
104 depends on CPU_THERMAL
105 depends on MFD_SYSCON
108 Support for Temperature Monitor (TEMPMON) found on Freescale i.MX SoCs.
109 It supports one critical trip point and one passive trip point. The
110 cpufreq is used as the cooling device to throttle CPUs when the
111 passive trip is crossed.
114 bool "SPEAr thermal sensor driver"
115 depends on PLAT_SPEAR
118 Enable this to plug the SPEAr thermal sensor driver into the Linux
122 tristate "Renesas R-Car thermal driver"
123 depends on ARCH_SHMOBILE
125 Enable this to plug the R-Car thermal sensor driver into the Linux
128 config KIRKWOOD_THERMAL
129 tristate "Temperature sensor on Marvell Kirkwood SoCs"
130 depends on ARCH_KIRKWOOD
133 Support for the Kirkwood thermal sensor driver into the Linux thermal
134 framework. Only kirkwood 88F6282 and 88F6283 have this sensor.
137 tristate "Temperature sensor on Marvell Dove SoCs"
141 Support for the Dove thermal sensor driver in the Linux thermal
144 config DB8500_THERMAL
145 bool "DB8500 thermal management"
146 depends on ARCH_U8500
149 Adds DB8500 thermal management implementation according to the thermal
150 management framework. A thermal zone with several trip points will be
151 created. Cooling devices can be bound to the trip points to cool this
152 thermal zone if trip points reached.
154 config ARMADA_THERMAL
155 tristate "Armada 370/XP thermal management"
156 depends on ARCH_MVEBU
159 Enable this option if you want to have support for thermal management
160 controller present in Armada 370 and Armada XP SoC.
162 config DB8500_CPUFREQ_COOLING
163 tristate "DB8500 cpufreq cooling"
164 depends on ARCH_U8500
165 depends on CPU_THERMAL
168 Adds DB8500 cpufreq cooling devices, and these cooling devices can be
169 bound to thermal zone trip points. When a trip point reached, the
170 bound cpufreq cooling device turns active to set CPU frequency low to
173 config INTEL_POWERCLAMP
174 tristate "Intel PowerClamp idle injection driver"
177 depends on CPU_SUP_INTEL
179 Enable this to enable Intel PowerClamp idle injection driver. This
180 enforce idle time which results in more package C-state residency. The
181 user interface is exposed via generic thermal framework.
183 config X86_PKG_TEMP_THERMAL
184 tristate "X86 package temperature thermal driver"
185 depends on X86_THERMAL_VECTOR
186 select THERMAL_GOV_USER_SPACE
189 Enable this to register CPU digital sensor for package temperature as
190 thermal zone. Each package will have its own thermal zone. There are
191 two trip points which can be set by user to get notifications via thermal
192 notification methods.
