13Description
14-----------
15
16This driver permits reading temperature sensor embedded inside Intel Core CPU.
17Temperature is measured in degrees Celsius and measurement resolution is
181 degree C. Valid temperatures are from 0 to TjMax degrees C, because
19the actual value of temperature register is in fact a delta from TjMax.
20
21Temperature known as TjMax is the maximum junction temperature of processor.
22Intel defines this temperature as 85C or 100C. At this temperature, protection
23mechanism will perform actions to forcibly cool down the processor. Alarm
24may be raised, if the temperature grows enough (more than TjMax) to trigger
25the Out-Of-Spec bit. Following table summarizes the exported sysfs files:
26
27temp1_input - Core temperature (in millidegrees Celsius).
28temp1_crit - Maximum junction temperature (in millidegrees Celsius).
29temp1_crit_alarm - Set when Out-of-spec bit is set, never clears.
30 Correct CPU operation is no longer guaranteed.
31temp1_label - Contains string "Core X", where X is processor
32 number.
33
34The TjMax temperature is set to 85 degrees C if undocumented model specific
35register (UMSR) 0xee has bit 30 set. If not the TjMax is 100 degrees C as
36(sometimes) documented in processor datasheet.

15Description
16-----------
17
18This driver implements support for the Maxim 6650/6651
19
20The 2 devices are very similar, but the Maxim 6550 has a reduced feature
21set, e.g. only one fan-input, instead of 4 for the 6651.
22
23The driver is not able to distinguish between the 2 devices.
24
25The driver provides the following sensor accesses in sysfs:
26
27fan1_input ro fan tachometer speed in RPM
28fan2_input ro "
29fan3_input ro "
30fan4_input ro "
31fan1_target rw desired fan speed in RPM (closed loop mode only)
32pwm1_enable rw regulator mode, 0=full on, 1=open loop, 2=closed loop
33pwm1 rw relative speed (0-255), 255=max. speed.
34 Used in open loop mode only.
35fan1_div rw sets the speed range the inputs can handle. Legal
36 values are 1, 2, 4, and 8. Use lower values for
37 faster fans.
38
39Module parameters
40-----------------
41
42If your board has a BIOS that initializes the MAX6650/6651 correctly, you can
43simply load your module without parameters. It won't touch the configuration
44registers then. If your board BIOS doesn't initialize the chip, or you want
45different settings, you can set the following parameters:
46
47voltage_12V: 5=5V fan, 12=12V fan, 0=don't change
48prescaler: Possible values are 1,2,4,8,16, or 0 for don't change
49clock: The clock frequency in Hz of the chip the driver should assume [254000]
50
51Please have a look at the MAX6650/6651 data sheet and make sure that you fully
52understand the meaning of these parameters before you attempt to change them.

171 * Assumptions:
172 *
173 * 1) The MAX6650/1 internal 254kHz clock frequency is set correctly. Use
174 * the clock module parameter if you need to fine tune this.
175 *
176 * 2) The prescaler (low three bits of the config register) has already
177 * been set to an appropriate value. Use the prescaler module parameter
178 * if your BIOS doesn't initialize the chip properly.
179 *
180 * The relevant equations are given on pages 21 and 22 of the datasheet.
181 *
182 * From the datasheet, the relevant equation when in regulation is:
183 *
184 * [fCLK / (128 x (KTACH + 1))] = 2 x FanSpeed / KSCALE
185 *
186 * where:
187 *
188 * fCLK is the oscillator frequency (either the 254kHz internal
189 * oscillator or the externally applied clock)
190 *
191 * KTACH is the value in the speed register
192 *
193 * FanSpeed is the speed of the fan in rps
194 *
195 * KSCALE is the prescaler value (1, 2, 4, 8, or 16)
196 *
197 * When reading, we need to solve for FanSpeed. When writing, we need to
198 * solve for KTACH.
199 *
200 * Note: this tachometer is completely separate from the tachometers
201 * used to measure the fan speeds. Only one fan's speed (fan1) is
