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
|
||||

|
||||

|
||||
7 - fan3
|
||||
8 - in2
|
||||
9 - in3
|
||||

||||

||||

||||

||||

||||

|
||||

||||

|
||||
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
|
||||
----------
|
||||
|
||||

|
||||
0 (stop) to 255 (full)
|
||||
pwm[1-3]_enable - this file controls mode of fan/temperature control:
|
||||
* 0 Disabled
|
||||
* 1 Manual mode
|
||||
* 2 Smart Fan II
|
||||
* 3 Thermal Cruise
|
||||
pwm[1-3]_mode - Select PWM of DC mode
|
||||
* 0 DC
|
||||
* 1 PWM
|
||||
thermal_cruise[1-3] - Selects the desired temperature for cruise (degC)
|
||||
tolerance[1-3] - Value in degrees of Celsius (degC) for +- T
|
||||
sf2_point[1-4]_fan[1-3] - four temperature points for each fan for Smart Fan II
|
||||
sf2_level[1-3]_fan[1-3] - three PWM/DC levels for each fan for Smart Fan II

|

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.
|
||||
|
||||

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.
|
||||
probe: 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 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,
|
||||
0x4d, 0x4e, 0x4f, I2C_CLIENT_END };
|
||||
/* Scan ISA address 0x290 */
|
||||
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.
|
||||
|
||||
A enum is automatically defined as follows:
|
||||
enum chips { any_chip, chip1, chip2, ... }

||||

The detect client function
|
||||
--------------------------
|
||||
|
||||
The detect client function is called by i2c_probe or i2c_detect.
|
||||
The `kind' parameter contains 0 if this call is due to a `force'
|
||||
parameter, and -1 otherwise (for i2c_detect, it contains 0 if
|
||||
this call is due to the generic `force' parameter, and the chip type
|
||||
number if it is due to a specific `force' parameter).
|
||||
The detect client function is called by i2c_probe. The `kind' parameter
|
||||
contains -1 for a probed detection, 0 for a forced detection, or a positive
|
||||
number for a forced detection with a chip type forced.
|
||||
|
||||
Below, some things are only needed if this is a `sensors' driver. Those
|
||||
parts are between /* SENSORS ONLY START */ and /* SENSORS ONLY END */
|
||||
markers.
|
||||
|
||||
This function should only return an error (any value != 0) if there is
|
||||
some reason why no more detection should be done anymore. If the
|
||||
detection just fails for this address, return 0.
|
||||
Returning an error different from -ENODEV in a detect function will cause
|
||||
the detection to stop: other addresses and adapters won't be scanned.
|
||||
This should only be done on fatal or internal errors, such as a memory
|
||||
shortage or i2c_attach_client failing.

Based on i2c/chips/eeprom.c
|
||||
|
||||
The MAX6875 has two EEPROM sections: config and user.
|
||||
At reset, the config EEPROM is read into the registers.
|
||||
The MAX6875 has a bank of registers and two banks of EEPROM.
|
||||
Address ranges are defined as follows:
|
||||
* 0x0000 - 0x0046 = configuration registers
|
||||
* 0x8000 - 0x8046 = configuration EEPROM
|
||||
* 0x8100 - 0x82FF = user EEPROM
|
||||
|
||||
This driver make 3 binary files available in sysfs:
|
||||
reg_config - direct access to the registers
|
||||
eeprom_config - acesses configuration eeprom space
|
||||
eeprom_user - free for application use
|
||||
This driver makes the user EEPROM available for read.
|
||||
|
||||
In our application, we put device serial & model numbers in user eeprom.
|
||||
The registers & config EEPROM should be accessed via i2c-dev.
|
||||
|
||||
Notes:
|
||||
1) The datasheet says that register 0x44 / EEPROM 0x8044 should NOT
|
||||
be overwritten, so the driver explicitly prevents that.
|
||||
2) It's a good idea to keep the config (0x45) locked in config EEPROM.
|
||||
You can temporarily enable config writes by changing register 0x45.
|
||||
The MAX6875 ignores the lowest address bit, so each chip responds to
|
||||
two addresses - 0x50/0x51 and 0x52/0x53.
|
||||
|
||||
Note that the MAX6875 uses i2c_smbus_write_byte_data() to set the read
|
||||
address, so this driver is destructive if loaded for the wrong EEPROM chip.
