14for providing initial documentation.

23Description
24-----------
25
26The Fintek F71805F/FG Super I/O chip includes complete hardware monitoring
27capabilities. It can monitor up to 9 voltages (counting its own power
28source), 3 fans and 3 temperature sensors.
29
30This chip also has fan controlling features, using either DC or PWM, in
31three different modes (one manual, two automatic). The driver doesn't
32support these features yet.
33
34The driver assumes that no more than one chip is present, which seems
35reasonable.
36
37
38Voltage Monitoring
39------------------
40
41Voltages are sampled by an 8-bit ADC with a LSB of 8 mV. The supported
42range is thus from 0 to 2.040 V. Voltage values outside of this range
43need external resistors. An exception is in0, which is used to monitor
44the chip's own power source (+3.3V), and is divided internally by a
45factor 2.
46
47The two LSB of the voltage limit registers are not used (always 0), so
48you can only set the limits in steps of 32 mV (before scaling).
49
50The wirings and resistor values suggested by Fintek are as follow:
51
52 pin expected
53 name use R1 R2 divider raw val.
54
55in0 VCC VCC3.3V int. int. 2.00 1.65 V
56in1 VIN1 VTT1.2V 10K - 1.00 1.20 V
57in2 VIN2 VRAM 100K 100K 2.00 ~1.25 V (1)
58in3 VIN3 VCHIPSET 47K 100K 1.47 2.24 V (2)

60in5 VIN5 +12V 200K 20K 11.00 1.05 V
61in6 VIN6 VCC1.5V 10K - 1.00 1.50 V
62in7 VIN7 VCORE 10K - 1.00 ~1.40 V (1)
63in8 VIN8 VSB5V 200K 47K 1.00 0.95 V
64
65(1) Depends on your hardware setup.
66(2) Obviously not correct, swapping R1 and R2 would make more sense.
67
68These values can be used as hints at best, as motherboard manufacturers
69are free to use a completely different setup. As a matter of fact, the
70Jetway K8M8MS uses a significantly different setup. You will have to
71find out documentation about your own motherboard, and edit sensors.conf
72accordingly.
73
74Each voltage measured has associated low and high limits, each of which
75triggers an alarm when crossed.
76
77
78Fan Monitoring
79--------------
80
81Fan rotation speeds are reported as 12-bit values from a gated clock
82signal. Speeds down to 366 RPM can be measured. There is no theoretical
83high limit, but values over 6000 RPM seem to cause problem. The effective
84resolution is much lower than you would expect, the step between different
85register values being 10 rather than 1.
86
87The chip assumes 2 pulse-per-revolution fans.
88
89An alarm is triggered if the rotation speed drops below a programmable
90limit or is too low to be measured.
91
92
93Temperature Monitoring
94----------------------
95
96Temperatures are reported in degrees Celsius. Each temperature measured
97has a high limit, those crossing triggers an alarm. There is an associated
98hysteresis value, below which the temperature has to drop before the
99alarm is cleared.
100
101All temperature channels are external, there is no embedded temperature
102sensor. Each channel can be used for connecting either a thermal diode
103or a thermistor. The driver reports the currently selected mode, but
104doesn't allow changing it. In theory, the BIOS should have configured
105everything properly.
