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
74 config THERMAL_GOV_USER_SPACE
75 bool "User_space thermal governor"
77 Enable this to let the user space manage the platform thermals.
80 bool "generic cpu cooling support"
83 This implements the generic cpu cooling mechanism through frequency
84 reduction. An ACPI version of this already exists
85 (drivers/acpi/processor_thermal.c).
86 This will be useful for platforms using the generic thermal interface
87 and not the ACPI interface.
89 If you want this support, you should say Y here.
91 config THERMAL_EMULATION
92 bool "Thermal emulation mode support"
94 Enable this option to make a emul_temp sysfs node in thermal zone
95 directory to support temperature emulation. With emulation sysfs node,
96 user can manually input temperature and test the different trip
97 threshold behaviour for simulation purpose.
99 WARNING: Be careful while enabling this option on production systems,
100 because userland can easily disable the thermal policy by simply
101 flooding this sysfs node with low temperature values.
104 tristate "Temperature sensor driver for Freescale i.MX SoCs"
105 depends on CPU_THERMAL
106 depends on MFD_SYSCON
109 Support for Temperature Monitor (TEMPMON) found on Freescale i.MX SoCs.
110 It supports one critical trip point and one passive trip point. The
111 cpufreq is used as the cooling device to throttle CPUs when the
112 passive trip is crossed.
115 bool "SPEAr thermal sensor driver"
116 depends on PLAT_SPEAR
119 Enable this to plug the SPEAr thermal sensor driver into the Linux
123 tristate "Renesas R-Car thermal driver"
124 depends on ARCH_SHMOBILE
126 Enable this to plug the R-Car thermal sensor driver into the Linux
129 config KIRKWOOD_THERMAL
130 tristate "Temperature sensor on Marvell Kirkwood SoCs"
131 depends on ARCH_KIRKWOOD
134 Support for the Kirkwood thermal sensor driver into the Linux thermal
135 framework. Only kirkwood 88F6282 and 88F6283 have this sensor.
138 tristate "Temperature sensor on Marvell Dove SoCs"
142 Support for the Dove thermal sensor driver in the Linux thermal
145 config DB8500_THERMAL
146 bool "DB8500 thermal management"
147 depends on ARCH_U8500
150 Adds DB8500 thermal management implementation according to the thermal
151 management framework. A thermal zone with several trip points will be
152 created. Cooling devices can be bound to the trip points to cool this
153 thermal zone if trip points reached.
155 config ARMADA_THERMAL
156 tristate "Armada 370/XP thermal management"
157 depends on ARCH_MVEBU
160 Enable this option if you want to have support for thermal management
161 controller present in Armada 370 and Armada XP SoC.
163 config DB8500_CPUFREQ_COOLING
164 tristate "DB8500 cpufreq cooling"
165 depends on ARCH_U8500
166 depends on CPU_THERMAL
169 Adds DB8500 cpufreq cooling devices, and these cooling devices can be
170 bound to thermal zone trip points. When a trip point reached, the
171 bound cpufreq cooling device turns active to set CPU frequency low to
174 config INTEL_POWERCLAMP
175 tristate "Intel PowerClamp idle injection driver"
178 depends on CPU_SUP_INTEL
180 Enable this to enable Intel PowerClamp idle injection driver. This
181 enforce idle time which results in more package C-state residency. The
182 user interface is exposed via generic thermal framework.
184 config X86_PKG_TEMP_THERMAL
185 tristate "X86 package temperature thermal driver"
186 depends on X86_THERMAL_VECTOR
187 select THERMAL_GOV_USER_SPACE
190 Enable this to register CPU digital sensor for package temperature as
191 thermal zone. Each package will have its own thermal zone. There are
192 two trip points which can be set by user to get notifications via thermal
193 notification methods.
