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"
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 tristate "Temperature sensor driver for Freescale i.MX SoCs"
119 depends on CPU_THERMAL
120 depends on MFD_SYSCON
123 Support for Temperature Monitor (TEMPMON) found on Freescale i.MX SoCs.
124 It supports one critical trip point and one passive trip point. The
125 cpufreq is used as the cooling device to throttle CPUs when the
126 passive trip is crossed.
129 bool "SPEAr thermal sensor driver"
130 depends on PLAT_SPEAR
133 Enable this to plug the SPEAr thermal sensor driver into the Linux
137 tristate "Renesas R-Car thermal driver"
138 depends on ARCH_SHMOBILE || COMPILE_TEST
141 Enable this to plug the R-Car thermal sensor driver into the Linux
144 config KIRKWOOD_THERMAL
145 tristate "Temperature sensor on Marvell Kirkwood SoCs"
146 depends on ARCH_KIRKWOOD || MACH_KIRKWOOD
149 Support for the Kirkwood thermal sensor driver into the Linux thermal
150 framework. Only kirkwood 88F6282 and 88F6283 have this sensor.
153 tristate "Temperature sensor on Marvell Dove SoCs"
157 Support for the Dove thermal sensor driver in the Linux thermal
160 config DB8500_THERMAL
161 bool "DB8500 thermal management"
162 depends on ARCH_U8500
165 Adds DB8500 thermal management implementation according to the thermal
166 management framework. A thermal zone with several trip points will be
167 created. Cooling devices can be bound to the trip points to cool this
168 thermal zone if trip points reached.
170 config ARMADA_THERMAL
171 tristate "Armada 370/XP thermal management"
172 depends on ARCH_MVEBU
175 Enable this option if you want to have support for thermal management
176 controller present in Armada 370 and Armada XP SoC.
178 config DB8500_CPUFREQ_COOLING
179 tristate "DB8500 cpufreq cooling"
180 depends on ARCH_U8500
181 depends on CPU_THERMAL
184 Adds DB8500 cpufreq cooling devices, and these cooling devices can be
185 bound to thermal zone trip points. When a trip point reached, the
186 bound cpufreq cooling device turns active to set CPU frequency low to
189 config INTEL_POWERCLAMP
190 tristate "Intel PowerClamp idle injection driver"
193 depends on CPU_SUP_INTEL
195 Enable this to enable Intel PowerClamp idle injection driver. This
196 enforce idle time which results in more package C-state residency. The
197 user interface is exposed via generic thermal framework.
199 config X86_PKG_TEMP_THERMAL
200 tristate "X86 package temperature thermal driver"
201 depends on X86_THERMAL_VECTOR
202 select THERMAL_GOV_USER_SPACE
205 Enable this to register CPU digital sensor for package temperature as
206 thermal zone. Each package will have its own thermal zone. There are
207 two trip points which can be set by user to get notifications via thermal
208 notification methods.
210 config ACPI_INT3403_THERMAL
211 tristate "ACPI INT3403 thermal driver"
212 depends on X86 && ACPI
214 Newer laptops and tablets that use ACPI may have thermal sensors
215 outside the core CPU/SOC for thermal safety reasons. These
216 temperature sensors are also exposed for the OS to use via the so
217 called INT3403 ACPI object. This driver will, on devices that have
218 such sensors, expose the temperature information from these sensors
219 to userspace via the normal thermal framework. This means that a wide
220 range of applications and GUI widgets can show this information to
221 the user or use this information for making decisions. For example,
222 the Intel Thermal Daemon can use this information to allow the user
223 to select his laptop to run without turning on the fans.
225 config INTEL_SOC_DTS_THERMAL
226 tristate "Intel SoCs DTS thermal driver"
227 depends on X86 && IOSF_MBI
229 Enable this to register Intel SoCs (e.g. Bay Trail) platform digital
230 temperature sensor (DTS). These SoCs have two additional DTSs in
231 addition to DTSs on CPU cores. Each DTS will be registered as a
232 thermal zone. There are two trip points. One of the trip point can
233 be set by user mode programs to get notifications via Linux thermal
234 notification methods.The other trip is a critical trip point, which
235 was set by the driver based on the TJ MAX temperature.
