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_BANG_BANG
88 bool "Bang Bang thermal governor"
91 Enable this to manage platform thermals using bang bang governor.
93 Say 'Y' here if you want to use two point temperature regulation
94 used for fans without throttling. Some fan drivers depend on this
95 governor to be enabled (e.g. acerhdf).
97 config THERMAL_GOV_USER_SPACE
98 bool "User_space thermal governor"
100 Enable this to let the user space manage the platform thermals.
103 bool "generic cpu cooling support"
105 depends on THERMAL_OF
107 This implements the generic cpu cooling mechanism through frequency
108 reduction. An ACPI version of this already exists
109 (drivers/acpi/processor_thermal.c).
110 This will be useful for platforms using the generic thermal interface
111 and not the ACPI interface.
113 If you want this support, you should say Y here.
116 bool "Generic clock cooling support"
117 depends on COMMON_CLK
120 This entry implements the generic clock cooling mechanism through
121 frequency clipping. Typically used to cool off co-processors. The
122 device that is configured to use this cooling mechanism will be
123 controlled to reduce clock frequency whenever temperature is high.
125 If you want this support, you should say Y here.
127 config THERMAL_EMULATION
128 bool "Thermal emulation mode support"
130 Enable this option to make a emul_temp sysfs node in thermal zone
131 directory to support temperature emulation. With emulation sysfs node,
132 user can manually input temperature and test the different trip
133 threshold behaviour for simulation purpose.
135 WARNING: Be careful while enabling this option on production systems,
136 because userland can easily disable the thermal policy by simply
137 flooding this sysfs node with low temperature values.
140 tristate "Temperature sensor driver for Freescale i.MX SoCs"
141 depends on CPU_THERMAL
142 depends on MFD_SYSCON
145 Support for Temperature Monitor (TEMPMON) found on Freescale i.MX SoCs.
146 It supports one critical trip point and one passive trip point. The
147 cpufreq is used as the cooling device to throttle CPUs when the
148 passive trip is crossed.
151 bool "SPEAr thermal sensor driver"
152 depends on PLAT_SPEAR
155 Enable this to plug the SPEAr thermal sensor driver into the Linux
159 tristate "Renesas R-Car thermal driver"
160 depends on ARCH_SHMOBILE || COMPILE_TEST
163 Enable this to plug the R-Car thermal sensor driver into the Linux
166 config KIRKWOOD_THERMAL
167 tristate "Temperature sensor on Marvell Kirkwood SoCs"
168 depends on MACH_KIRKWOOD
171 Support for the Kirkwood thermal sensor driver into the Linux thermal
172 framework. Only kirkwood 88F6282 and 88F6283 have this sensor.
175 tristate "Temperature sensor on Marvell Dove SoCs"
176 depends on ARCH_DOVE || MACH_DOVE
179 Support for the Dove thermal sensor driver in the Linux thermal
182 config DB8500_THERMAL
183 bool "DB8500 thermal management"
184 depends on ARCH_U8500
187 Adds DB8500 thermal management implementation according to the thermal
188 management framework. A thermal zone with several trip points will be
189 created. Cooling devices can be bound to the trip points to cool this
190 thermal zone if trip points reached.
192 config ARMADA_THERMAL
193 tristate "Armada 370/XP thermal management"
194 depends on ARCH_MVEBU
197 Enable this option if you want to have support for thermal management
198 controller present in Armada 370 and Armada XP SoC.
200 config DB8500_CPUFREQ_COOLING
201 tristate "DB8500 cpufreq cooling"
202 depends on ARCH_U8500
203 depends on CPU_THERMAL
206 Adds DB8500 cpufreq cooling devices, and these cooling devices can be
207 bound to thermal zone trip points. When a trip point reached, the
208 bound cpufreq cooling device turns active to set CPU frequency low to
211 config INTEL_POWERCLAMP
212 tristate "Intel PowerClamp idle injection driver"
215 depends on CPU_SUP_INTEL
217 Enable this to enable Intel PowerClamp idle injection driver. This
218 enforce idle time which results in more package C-state residency. The
219 user interface is exposed via generic thermal framework.
221 config X86_PKG_TEMP_THERMAL
222 tristate "X86 package temperature thermal driver"
223 depends on X86_THERMAL_VECTOR
224 select THERMAL_GOV_USER_SPACE
227 Enable this to register CPU digital sensor for package temperature as
228 thermal zone. Each package will have its own thermal zone. There are
229 two trip points which can be set by user to get notifications via thermal
230 notification methods.
232 config INTEL_SOC_DTS_THERMAL
233 tristate "Intel SoCs DTS thermal driver"
234 depends on X86 && IOSF_MBI
236 Enable this to register Intel SoCs (e.g. Bay Trail) platform digital
237 temperature sensor (DTS). These SoCs have two additional DTSs in
238 addition to DTSs on CPU cores. Each DTS will be registered as a
239 thermal zone. There are two trip points. One of the trip point can
240 be set by user mode programs to get notifications via Linux thermal
241 notification methods.The other trip is a critical trip point, which
242 was set by the driver based on the TJ MAX temperature.
244 config INT340X_THERMAL
245 tristate "ACPI INT340X thermal drivers"
246 depends on X86 && ACPI
247 select THERMAL_GOV_USER_SPACE
248 select ACPI_THERMAL_REL
251 Newer laptops and tablets that use ACPI may have thermal sensors and
252 other devices with thermal control capabilities outside the core
253 CPU/SOC, for thermal safety reasons.
254 They are exposed for the OS to use via the INT3400 ACPI device object
255 as the master, and INT3401~INT340B ACPI device objects as the slaves.
256 Enable this to expose the temperature information and cooling ability
257 from these objects to userspace via the normal thermal framework.
258 This means that a wide range of applications and GUI widgets can show
259 the information to the user or use this information for making
260 decisions. For example, the Intel Thermal Daemon can use this
261 information to allow the user to select his laptop to run without
