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
45 config THERMAL_WRITABLE_TRIPS
46 bool "Enable writable trip points"
48 This option allows the system integrator to choose whether
49 trip temperatures can be changed from userspace. The
50 writable trips need to be specified when setting up the
51 thermal zone but the choice here takes precedence.
53 Say 'Y' here if you would like to allow userspace tools to
54 change trip temperatures.
57 prompt "Default Thermal governor"
58 default THERMAL_DEFAULT_GOV_STEP_WISE
60 This option sets which thermal governor shall be loaded at
61 startup. If in doubt, select 'step_wise'.
63 config THERMAL_DEFAULT_GOV_STEP_WISE
65 select THERMAL_GOV_STEP_WISE
67 Use the step_wise governor as default. This throttles the
68 devices one step at a time.
70 config THERMAL_DEFAULT_GOV_FAIR_SHARE
72 select THERMAL_GOV_FAIR_SHARE
74 Use the fair_share governor as default. This throttles the
75 devices based on their 'contribution' to a zone. The
76 contribution should be provided through platform data.
78 config THERMAL_DEFAULT_GOV_USER_SPACE
80 select THERMAL_GOV_USER_SPACE
82 Select this if you want to let the user space manage the
85 config THERMAL_DEFAULT_GOV_POWER_ALLOCATOR
86 bool "power_allocator"
87 select THERMAL_GOV_POWER_ALLOCATOR
89 Select this if you want to control temperature based on
90 system and device power allocation. This governor can only
91 operate on cooling devices that implement the power API.
95 config THERMAL_GOV_FAIR_SHARE
96 bool "Fair-share thermal governor"
98 Enable this to manage platform thermals using fair-share governor.
100 config THERMAL_GOV_STEP_WISE
101 bool "Step_wise thermal governor"
103 Enable this to manage platform thermals using a simple linear
106 config THERMAL_GOV_BANG_BANG
107 bool "Bang Bang thermal governor"
110 Enable this to manage platform thermals using bang bang governor.
112 Say 'Y' here if you want to use two point temperature regulation
113 used for fans without throttling. Some fan drivers depend on this
114 governor to be enabled (e.g. acerhdf).
116 config THERMAL_GOV_USER_SPACE
117 bool "User_space thermal governor"
119 Enable this to let the user space manage the platform thermals.
121 config THERMAL_GOV_POWER_ALLOCATOR
122 bool "Power allocator thermal governor"
124 Enable this to manage platform thermals by dynamically
125 allocating and limiting power to devices.
128 bool "generic cpu cooling support"
130 depends on THERMAL_OF
132 This implements the generic cpu cooling mechanism through frequency
133 reduction. An ACPI version of this already exists
134 (drivers/acpi/processor_thermal.c).
135 This will be useful for platforms using the generic thermal interface
136 and not the ACPI interface.
138 If you want this support, you should say Y here.
141 bool "Generic clock cooling support"
142 depends on COMMON_CLK
145 This entry implements the generic clock cooling mechanism through
146 frequency clipping. Typically used to cool off co-processors. The
147 device that is configured to use this cooling mechanism will be
148 controlled to reduce clock frequency whenever temperature is high.
150 config DEVFREQ_THERMAL
151 bool "Generic device cooling support"
152 depends on PM_DEVFREQ
155 This implements the generic devfreq cooling mechanism through
156 frequency reduction for devices using devfreq.
158 This will throttle the device by limiting the maximum allowed DVFS
159 frequency corresponding to the cooling level.
161 In order to use the power extensions of the cooling device,
162 devfreq should use the simple_ondemand governor.
164 If you want this support, you should say Y here.
166 config THERMAL_EMULATION
167 bool "Thermal emulation mode support"
169 Enable this option to make a emul_temp sysfs node in thermal zone
170 directory to support temperature emulation. With emulation sysfs node,
171 user can manually input temperature and test the different trip
172 threshold behaviour for simulation purpose.
174 WARNING: Be careful while enabling this option on production systems,
175 because userland can easily disable the thermal policy by simply
176 flooding this sysfs node with low temperature values.
