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
87 config THERMAL_GOV_USER_SPACE
88 bool "User_space thermal governor"
90 Enable this to let the user space manage the platform thermals.
93 bool "generic cpu cooling support"
96 This implements the generic cpu cooling mechanism through frequency
97 reduction. An ACPI version of this already exists
98 (drivers/acpi/processor_thermal.c).
99 This will be useful for platforms using the generic thermal interface
100 and not the ACPI interface.
102 If you want this support, you should say Y here.
104 config THERMAL_EMULATION
105 bool "Thermal emulation mode support"
107 Enable this option to make a emul_temp sysfs node in thermal zone
108 directory to support temperature emulation. With emulation sysfs node,
109 user can manually input temperature and test the different trip
110 threshold behaviour for simulation purpose.
112 WARNING: Be careful while enabling this option on production systems,
113 because userland can easily disable the thermal policy by simply
114 flooding this sysfs node with low temperature values.
117 tristate "Temperature sensor driver for Freescale i.MX SoCs"
118 depends on CPU_THERMAL
119 depends on MFD_SYSCON
122 Support for Temperature Monitor (TEMPMON) found on Freescale i.MX SoCs.
123 It supports one critical trip point and one passive trip point. The
124 cpufreq is used as the cooling device to throttle CPUs when the
125 passive trip is crossed.
128 bool "SPEAr thermal sensor driver"
129 depends on PLAT_SPEAR
132 Enable this to plug the SPEAr thermal sensor driver into the Linux
136 tristate "Renesas R-Car thermal driver"
137 depends on ARCH_SHMOBILE
139 Enable this to plug the R-Car thermal sensor driver into the Linux
142 config KIRKWOOD_THERMAL
143 tristate "Temperature sensor on Marvell Kirkwood SoCs"
144 depends on ARCH_KIRKWOOD
147 Support for the Kirkwood thermal sensor driver into the Linux thermal
148 framework. Only kirkwood 88F6282 and 88F6283 have this sensor.
151 tristate "Temperature sensor on Marvell Dove SoCs"
155 Support for the Dove thermal sensor driver in the Linux thermal
158 config DB8500_THERMAL
159 bool "DB8500 thermal management"
160 depends on ARCH_U8500
163 Adds DB8500 thermal management implementation according to the thermal
164 management framework. A thermal zone with several trip points will be
165 created. Cooling devices can be bound to the trip points to cool this
166 thermal zone if trip points reached.
168 config ARMADA_THERMAL
169 tristate "Armada 370/XP thermal management"
170 depends on ARCH_MVEBU
173 Enable this option if you want to have support for thermal management
174 controller present in Armada 370 and Armada XP SoC.
176 config DB8500_CPUFREQ_COOLING
177 tristate "DB8500 cpufreq cooling"
178 depends on ARCH_U8500
179 depends on CPU_THERMAL
182 Adds DB8500 cpufreq cooling devices, and these cooling devices can be
183 bound to thermal zone trip points. When a trip point reached, the
184 bound cpufreq cooling device turns active to set CPU frequency low to
187 config INTEL_POWERCLAMP
188 tristate "Intel PowerClamp idle injection driver"
191 depends on CPU_SUP_INTEL
193 Enable this to enable Intel PowerClamp idle injection driver. This
194 enforce idle time which results in more package C-state residency. The
195 user interface is exposed via generic thermal framework.
197 config X86_PKG_TEMP_THERMAL
198 tristate "X86 package temperature thermal driver"
199 depends on X86_THERMAL_VECTOR
200 select THERMAL_GOV_USER_SPACE
203 Enable this to register CPU digital sensor for package temperature as
204 thermal zone. Each package will have its own thermal zone. There are
205 two trip points which can be set by user to get notifications via thermal
206 notification methods.
