Kernel driver w83792d
=====================
Supported chips:
* Winbond W83792D
Prefix: 'w83792d'

Module Parameters
-----------------
* init int
(default 1)
Use 'init=0' to bypass initializing the chip.
Try this if your computer crashes when you load the module.
* force_subclients=bus,caddr,saddr,saddr
This is used to force the i2c addresses for subclients of
a certain chip. Example usage is `force_subclients=0,0x2f,0x4a,0x4b'
to force the subclients of chip 0x2f on bus 0 to i2c addresses
0x4a and 0x4b.
Description
-----------
This driver implements support for the Winbond W83792AD/D.
Detection of the chip can sometimes be foiled because it can be in an
internal state that allows no clean access (Bank with ID register is not
currently selected). If you know the address of the chip, use a 'force'
parameter; this will put it into a more well-behaved state first.
The driver implements three temperature sensors, seven fan rotation speed
sensors, nine voltage sensors, and two automatic fan regulation
strategies called: Smart Fan I (Thermal Cruise mode) and Smart Fan II.
Automatic fan control mode is possible only for fan1-fan3. Fan4-fan7 can run
synchronized with selected fan (fan1-fan3). This functionality and manual PWM
control for fan4-fan7 is not yet implemented.
Temperatures are measured in degrees Celsius and measurement resolution is 1
degC for temp1 and 0.5 degC for temp2 and temp3. An alarm is triggered when
the temperature gets higher than the Overtemperature Shutdown value; it stays
on until the temperature falls below the Hysteresis value.
Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
triggered if the rotation speed has dropped below a programmable limit. Fan
readings can be divided by a programmable divider (1, 2, 4, 8, 16, 32, 64 or
128) to give the readings more range or accuracy.
Voltage sensors (also known as IN sensors) report their values in millivolts.
An alarm is triggered if the voltage has crossed a programmable minimum
or maximum limit.
Alarms are provided as output from "realtime status register". Following bits
are defined:
bit - alarm on:
0 - in0
1 - in1
2 - temp1
3 - temp2
4 - temp3
5 - fan1
6 - fan2
7 - fan3
8 - in2
9 - in3
10 - in4
11 - in5
12 - in6
13 - VID change
14 - chassis
15 - fan7
16 - tart1
17 - tart2
18 - tart3
19 - in7
20 - in8
21 - fan4
22 - fan5
23 - fan6
Tart will be asserted while target temperature cannot be achieved after 3 minutes
of full speed rotation of corresponding fan.
In addition to the alarms described above, there is a CHAS alarm on the chips
which triggers if your computer case is open (This one is latched, contrary
to realtime alarms).
The chips only update values each 3 seconds; reading them more often will
do no harm, but will return 'old' values.
W83792D PROBLEMS
----------------
Known problems:
- This driver is only for Winbond W83792D C version device, there
are also some motherboards with B version W83792D device. The
calculation method to in6-in7(measured value, limits) is a little
different between C and B version. C or B version can be identified
by CR[0x49h].
- The function of vid and vrm has not been finished, because I'm NOT
very familiar with them. Adding support is welcome.
  - The function of chassis open detection needs more tests.
- If you have ASUS server board and chip was not found: Then you will
need to upgrade to latest (or beta) BIOS. If it does not help please
contact us.
Fan control
-----------
Manual mode
-----------
Works as expected. You just need to specify desired PWM/DC value (fan speed)
in appropriate pwm# file.
Thermal cruise
--------------
In this mode, W83792D provides the Smart Fan system to automatically control
fan speed to keep the temperatures of CPU and the system within specific
range. At first a wanted temperature and interval must be set. This is done
via thermal_cruise# file. The tolerance# file serves to create T +- tolerance
interval. The fan speed will be lowered as long as the current temperature
remains below the thermal_cruise# +- tolerance# value. Once the temperature
exceeds the high limit (T+tolerance), the fan will be turned on with a
specific speed set by pwm# and automatically controlled its PWM duty cycle
with the temperature varying. Three conditions may occur:
(1) If the temperature still exceeds the high limit, PWM duty
cycle will increase slowly.
(2) If the temperature goes below the high limit, but still above the low
limit (T-tolerance), the fan speed will be fixed at the current speed because
the temperature is in the target range.
(3) If the temperature goes below the low limit, PWM duty cycle will decrease
slowly to 0 or a preset stop value until the temperature exceeds the low
limit. (The preset stop value handling is not yet implemented in driver)
Smart Fan II
------------
W83792D also provides a special mode for fan. Four temperature points are
available. When related temperature sensors detects the temperature in preset
temperature region (sf2_point@_fan# +- tolerance#) it will cause fans to run
on programmed value from sf2_level@_fan#. You need to set four temperatures
for each fan.
/sys files
----------
pwm[1-3] - this file stores PWM duty cycle or DC value (fan speed) in range:
0 (stop) to 255 (full)
pwm[1-3]_enable - this file controls mode of fan/temperature control:
* 0 Disabled

* 2 Smart Fan II
* 3 Thermal Cruise

The Maxim MAX6874 is a similar, mostly compatible device, with more intputs
and outputs:
vin gpi vout
MAX6874 6 4 8
MAX6875 4 3 5
MAX6874 chips can have four different addresses (as opposed to only two for
the MAX6875). The additional addresses (0x54 and 0x56) are not probed by
this driver by default, but the probe module parameter can be used if
needed.
See the datasheet for details on how to program the EEPROM.
See the datasheet for more information.
Sysfs entries
-------------
eeprom_user - 512 bytes of user-defined EEPROM space. Only writable if
allow_write was set and register 0x43 is 0.
eeprom_config - 70 bytes of config EEPROM. Note that changes will not get
loaded into register space until a power cycle or device reset.
reg_config - 70 bytes of register space. Any changes take affect immediately.
eeprom - 512 bytes of user-defined EEPROM space.
General Remarks
---------------
A typical application will require that the EEPROMs be programmed once and
never altered afterwards.
Valid addresses for the MAX6875 are 0x50 and 0x52.
Valid addresses for the MAX6874 are 0x50, 0x52, 0x54 and 0x56.
The driver does not probe any address, so you must force the address.
Example:
$ modprobe max6875 force=0,0x50
The MAX6874/MAX6875 ignores address bit 0, so this driver attaches to multiple
addresses. For example, for address 0x50, it also reserves 0x51.
The even-address instance is called 'max6875', the odd one is 'max6875 subclient'.
Programming the chip using i2c-dev
----------------------------------
Use the i2c-dev interface to access and program the chips.
Reads and writes are performed differently depending on the address range.
The configuration registers are at addresses 0x00 - 0x45.
Use i2c_smbus_write_byte_data() to write a register and
i2c_smbus_read_byte_data() to read a register.
The command is the register number.
Examples:
To write a 1 to register 0x45:
i2c_smbus_write_byte_data(fd, 0x45, 1);
To read register 0x45:
value = i2c_smbus_read_byte_data(fd, 0x45);
The configuration EEPROM is at addresses 0x8000 - 0x8045.
The user EEPROM is at addresses 0x8100 - 0x82ff.
Use i2c_smbus_write_word_data() to write a byte to EEPROM.
The command is the upper byte of the address: 0x80, 0x81, or 0x82.
The data word is the lower part of the address or'd with data << 8.
cmd = address >> 8;
val = (address & 0xff) | (data << 8);
Example:
To write 0x5a to address 0x8003:
i2c_smbus_write_word_data(fd, 0x80, 0x5a03);
Reading data from the EEPROM is a little more complicated.
Use i2c_smbus_write_byte_data() to set the read address and then
i2c_smbus_read_byte() or i2c_smbus_read_i2c_block_data() to read the data.
Example:
To read data starting at offset 0x8100, first set the address:
i2c_smbus_write_byte_data(fd, 0x81, 0x00);
And then read the data
value = i2c_smbus_read_byte(fd);
or
count = i2c_smbus_read_i2c_block_data(fd, 0x84, buffer);
The block read should read 16 bytes.
0x84 is the block read command.
See the datasheet for more details.

enum chips { any_chip, foo, bar, ... }
You can then (and certainly should) use it in the driver code.
Note that you *have* to call the defined variable `normal_i2c',
without any prefix!
Probing classes (sensors)
-------------------------
If you write a `sensors' driver, you use a slightly different interface.
As well as I2C addresses, we have to cope with ISA addresses. Also, we
use a enum of chip types. Don't forget to include `sensors.h'.
The following lists are used internally. They are all lists of integers.
normal_i2c: filled in by the module writer. Terminated by SENSORS_I2C_END.
A list of I2C addresses which should normally be examined.
normal_isa: filled in by the module writer. Terminated by SENSORS_ISA_END.
A list of ISA addresses which should normally be examined.

A list of pairs. The first value is a bus number (SENSORS_ISA_BUS for
the ISA bus, -1 for any I2C bus), the second is the address. These
addresses are also probed, as if they were in the 'normal' list.
ignore: insmod parameter. Initialize this list with SENSORS_I2C_END values.
A list of pairs. The first value is a bus number (SENSORS_ISA_BUS for
the ISA bus, -1 for any I2C bus), the second is the I2C address. These
addresses are never probed. This parameter overrules 'normal' and
'probe', but not the 'force' lists.
Also used is a list of pointers to sensors_force_data structures:
force_data: insmod parameters. A list, ending with an element of which
the force field is NULL.
Each element contains the type of chip and a list of pairs.
The first value is a bus number (SENSORS_ISA_BUS for the ISA bus,
-1 for any I2C bus), the second is the address.
These are automatically translated to insmod variables of the form
force_foo.
So we have a generic insmod variabled `force', and chip-specific variables
`force_CHIPNAME'.
Fortunately, as a module writer, you just have to define the `normal_i2c'
and `normal_isa' parameters, and define what chip names are used.
The complete declaration could look like this:
/* Scan i2c addresses 0x37, and 0x48 to 0x4f */
static unsigned short normal_i2c[] = { 0x37, 0x48, 0x49, 0x4a, 0x4b, 0x4c,

static unsigned int normal_isa[] = {0x0290,SENSORS_ISA_END};
/* Define chips foo and bar, as well as all module parameters and things */
SENSORS_INSMOD_2(foo,bar);
If you have one chip, you use macro SENSORS_INSMOD_1(chip), if you have 2
you use macro SENSORS_INSMOD_2(chip1,chip2), etc. If you do not want to
bother with chip types, you can use SENSORS_INSMOD_0.

AMD Opteron processors don't follow the Intel specifications.
I'm going to "make up" 2.4 as the spec number for the Opterons.
No good reason just a mnemonic for the 24x Opteron processor

Opteron VID encoding is:

00001 = 1.525 V

11110 = 0.800 V
11111 = 0.000 V (off)
