119Fan Control
120-----------
121
122Both PWM (pulse-width modulation) and DC fan speed control methods are
123supported. The right one to use depends on external circuitry on the
124motherboard, so the driver assumes that the BIOS set the method
125properly. The driver will report the method, but won't let you change
126it.
127
128When the PWM method is used, you can select the operating frequency,
129from 187.5 kHz (default) to 31 Hz. The best frequency depends on the
130fan model. As a rule of thumb, lower frequencies seem to give better
131control, but may generate annoying high-pitch noise. Fintek recommends
132not going below 1 kHz, as the fan tachometers get confused by lower
133frequencies as well.
134
135When the DC method is used, Fintek recommends not going below 5 V, which
136corresponds to a pwm value of 106 for the driver. The driver doesn't
137enforce this limit though.
138
139Three different fan control modes are supported:
140
141* Manual mode
142 You ask for a specific PWM duty cycle or DC voltage.
143
144* Fan speed mode
145 You ask for a specific fan speed. This mode assumes that pwm1
146 corresponds to fan1, pwm2 to fan2 and pwm3 to fan3.
147
148* Temperature mode
149 You define 3 temperature/fan speed trip points, and the fan speed is
150 adjusted depending on the measured temperature, using interpolation.
151 This mode is not yet supported by the driver.

56Hardware Interfaces
57-------------------
58
59All the chips suported by this driver are LPC Super-I/O chips, accessed
60through the LPC bus (ISA-like I/O ports). The IT8712F additionally has an
61SMBus interface to the hardware monitoring functions. This driver no
62longer supports this interface though, as it is slower and less reliable
63than the ISA access, and was only available on a small number of
64motherboard models.

16Description
17-----------
18
19The National Semiconductor Super I/O chip includes complete hardware
20monitoring capabilities. It can monitor up to 18 voltages, 8 fans and
216 temperature sensors. Only the fans are supported at the moment.
22
23This chip also has fan controlling features, which are not yet supported
24by this driver either.
25
26The driver assumes that no more than one chip is present, which seems
27reasonable.

30Fan Monitoring
31--------------
32
33Fan rotation speeds are reported as 14-bit values from a gated clock
34signal. Speeds down to 83 RPM can be measured.
35
36An alarm is triggered if the rotation speed drops below a programmable
37limit. Another alarm is triggered if the speed is too low to to be measured
38(including stalled or missing fan).

30Description
31-----------
32
33This driver implements support for Winbond W83793G/W83793R chips.
34
35* Exported features
36 This driver exports 10 voltage sensors, up to 12 fan tachometer inputs,
37 6 remote temperatures, up to 8 sets of PWM fan controls, SmartFan
38 (automatic fan speed control) on all temperature/PWM combinations, 2
39 sets of 6-pin CPU VID input.
40
41* Sensor resolutions
42 If your motherboard maker used the reference design, the resolution of
43 voltage0-2 is 2mV, resolution of voltage3/4/5 is 16mV, 8mV for voltage6,
44 24mV for voltage7/8. Temp1-4 have a 0.25 degree Celsius resolution,
45 temp5-6 have a 1 degree Celsiis resolution.
46
47* Temperature sensor types
48 Temp1-4 have 3 possible types. It can be read from (and written to)
49 temp[1-4]_type.
50 - If the value of 0, the related temperature channel stops
51 monitoring.
52 - If the value is 3, it starts monitoring using a remote termal diode
53 (default).
54 - If the value is 5, it starts monitoring using the temperature sensor
55 in AMD CPU and get result by AMDSI.
56 - If the value is 6, it starts monitoring using the temperature sensor
57 in Intel CPU and get result by PECI.
58 Temp5-6 can be connected to external thermistors (value of
59 temp[5-6]_type is 4). They can also be disabled (value is 0).
60
61* Alarm mechanism
62 For voltage sensors, an alarm triggers if the measured value is below
63 the low voltage limit or over the high voltage limit.
64 For temperature sensors, an alarm triggers if the measured value goes
65 above the high temperature limit, and wears off only after the measured
66 value drops below the hysteresis value.
67 For fan sensors, an alarm triggers if the measured value is below the
68 low speed limit.
69
70* SmartFan/PWM control
71 If you want to set a pwm fan to manual mode, you just need to make sure it
72 is not controlled by any temp channel, for example, you want to set fan1
73 to manual mode, you need to check the value of temp[1-6]_fan_map, make
74 sure bit 0 is cleared in the 6 values. And then set the pwm1 value to
75 control the fan.
76
77 Each temperature channel can control all the 8 PWM outputs (by setting the
78 corresponding bit in tempX_fan_map), you can set the temperature channel
79 mode using temp[1-6]_pwm_enable, 2 is Thermal Cruise mode and 3
80 is the SmartFanII mode. Temperature channels will try to speed up or
81 slow down all controlled fans, this means one fan can receive different
82 PWM value requests from different temperature channels, but the chip
83 will always pick the safest (max) PWM value for each fan.
84
85 In Thermal Cruise mode, the chip attempts to keep the temperature at a
86 predefined value, within a tolerance margin. So if tempX_input >
87 thermal_cruiseX + toleranceX, the chip will increase the PWM value,
88 if tempX_input < thermal_cruiseX - toleranceX, the chip will decrease
89 the PWM value. If the temperature is within the tolerance range, the PWM
90 value is left unchanged.
91
92 SmartFanII works differently, you have to define up to 7 PWM, temperature
93 trip points, defining a PWM/temperature curve which the chip will follow.
94 While not fundamentally different from the Thermal Cruise mode, the
95 implementation is quite different, giving you a finer-grained control.
96
97* Chassis
98 If the case open alarm triggers, it will stay in this state unless cleared
99 by any write to the sysfs file "chassis".
100
101* VID and VRM
102 The VRM version is detected automatically, don't modify the it unless you
103 *do* know the cpu VRM version and it's not properly detected.
104
105
106Notes
107-----
108
109 Only Fan1-5 and PWM1-3 are guaranteed to always exist, other fan inputs and
110 PWM outputs may or may not exist depending on the chip pin configuration.
