* Abit uGuru (Hardware Monitor part only)
|
||||
Prefix: 'abituguru'
|
||||
Addresses scanned: ISA 0x0E0
|
||||
Datasheet: Not available, this driver is based on reverse engineering.
|
||||
A "Datasheet" has been written based on the reverse engineering it
|
||||
should be available in the same dir as this file under the name

Module Parameters
|
||||
-----------------
|
||||
|
||||
* force: bool Force detection. Note this parameter only causes the
|
||||
detection to be skipped, if the uGuru can't be read
|
||||
the module initialization (insmod) will still fail.
|
||||
* fan_sensors: int Tell the driver how many fan speed sensors there are
|
||||
on your motherboard. Default: 0 (autodetect).
|
||||
* pwms: int Tell the driver how many fan speed controls (fan
|
||||
pwms) your motherboard has. Default: 0 (autodetect).
|
||||
* verbose: int How verbose should the driver be? (0-3):
|
||||
0 normal output
|
||||
1 + verbose error reporting
|
||||
2 + sensors type probing info\n"
|
||||
3 + retryable error reporting
|
||||
Default: 2 (the driver is still in the testing phase)
|
||||
|
||||
Notice if you need any of the first three options above please insmod the
|
||||
driver with verbose set to 3 and mail me <j.w.r.degoede@hhs.nl> the output of:

Description
|
||||
-----------
|
||||
|
||||
This driver supports the hardware monitoring features of the Abit uGuru chip
|
||||
found on Abit uGuru featuring motherboards (most modern Abit motherboards).
|
||||
|
||||
The uGuru chip in reality is a Winbond W83L950D in disguise (despite Abit
|
||||
claiming it is "a new microprocessor designed by the ABIT Engineers").
|
||||
Unfortunatly this doesn't help since the W83L950D is a generic
|
||||
microcontroller with a custom Abit application running on it.
|
||||
|
||||
Despite Abit not releasing any information regarding the uGuru, Olle
|
||||
Sandberg <ollebull@gmail.com> has managed to reverse engineer the sensor part
|
||||
of the uGuru. Without his work this driver would not have been possible.
|
||||
|
||||
Known Issues
|
||||
------------
|
||||
|
||||
The voltage and frequency control parts of the Abit uGuru are not supported.

uGuru datasheet
|
||||
===============
|
||||
|
||||
First of all, what I know about uGuru is no fact based on any help, hints or
|
||||
datasheet from Abit. The data I have got on uGuru have I assembled through
|
||||
my weak knowledge in "backwards engineering".
|
||||
And just for the record, you may have noticed uGuru isn't a chip developed by
|
||||
Abit, as they claim it to be. It's realy just an microprocessor (uC) created by
|
||||
Winbond (W83L950D). And no, reading the manual for this specific uC or
|
||||
mailing Windbond for help won't give any usefull data about uGuru, as it is
|
||||
the program inside the uC that is responding to calls.
|
||||
|
||||
Olle Sandberg <ollebull@gmail.com>, 2005-05-25
|
||||
|
||||
|
||||
Original version by Olle Sandberg who did the heavy lifting of the initial
|
||||
reverse engineering. This version has been almost fully rewritten for clarity
|
||||
and extended with write support and info on more databanks, the write support
|
||||
is once again reverse engineered by Olle the additional databanks have been
|
||||
reverse engineered by me. I would like to express my thanks to Olle, this
|
||||
document and the Linux driver could not have been written without his efforts.
|
||||
|
||||
Note: because of the lack of specs only the sensors part of the uGuru is
|
||||
described here and not the CPU / RAM / etc voltage & frequency control.

||||
|
||||
|
||||
Detection
|
||||
=========
|
||||
|
||||
As far as known the uGuru is always placed at and using the (ISA) I/O-ports
|
||||
0xE0 and 0xE4, so we don't have to scan any port-range, just check what the two
|
||||
ports are holding for detection. We will refer to 0xE0 as CMD (command-port)
|
||||
and 0xE4 as DATA because Abit refers to them with these names.
|
||||
|
||||
If DATA holds 0x00 or 0x08 and CMD holds 0x00 or 0xAC an uGuru could be
|
||||
present. We have to check for two different values at data-port, because
|
||||
after a reboot uGuru will hold 0x00 here, but if the driver is removed and
|
||||
later on attached again data-port will hold 0x08, more about this later.
|
||||
|
||||
After wider testing of the Linux kernel driver some variants of the uGuru have
|
||||
turned up which will hold 0x00 instead of 0xAC at the CMD port, thus we also
|
||||
have to test CMD for two different values. On these uGuru's DATA will initally
|
||||
hold 0x09 and will only hold 0x08 after reading CMD first, so CMD must be read
|
||||
first!
|
||||
|
||||
To be really sure an uGuru is present a test read of one or more register
|
||||
sets should be done.
|
||||
|
||||
|
||||
Reading / Writing
|
||||
=================
|
||||
|
||||
Addressing
|
||||
----------
|
||||
|
||||
The uGuru has a number of different addressing levels. The first addressing
|
||||
level we will call banks. A bank holds data for one or more sensors. The data
|
||||
in a bank for a sensor is one or more bytes large.
|
||||
|
||||
The number of bytes is fixed for a given bank, you should always read or write
|
||||
that many bytes, reading / writing more will fail, the results when writing
|
||||
less then the number of bytes for a given bank are undetermined.
|
||||
|
||||
See below for all known bank addresses, numbers of sensors in that bank,
|
||||
number of bytes data per sensor and contents/meaning of those bytes.
|
||||
|
||||
Although both this document and the kernel driver have kept the sensor
|
||||
terminoligy for the addressing within a bank this is not 100% correct, in
|
||||
bank 0x24 for example the addressing within the bank selects a PWM output not
|
||||
a sensor.
|
||||
|
||||
Notice that some banks have both a read and a write address this is how the
|
||||
uGuru determines if a read from or a write to the bank is taking place, thus
|
||||
when reading you should always use the read address and when writing the
|
||||
write address. The write address is always one (1) more then the read address.
|
||||
|
||||
|
||||
uGuru ready
|
||||
-----------
|
||||
|
||||
Before you can read from or write to the uGuru you must first put the uGuru
|
||||
in "ready" mode.
|
||||
|
||||
To put the uGuru in ready mode first write 0x00 to DATA and then wait for DATA
|
||||
to hold 0x09, DATA should read 0x09 within 250 read cycles.
|
||||
|
||||
Next CMD _must_ be read and should hold 0xAC, usually CMD will hold 0xAC the
|
||||
first read but sometimes it takes a while before CMD holds 0xAC and thus it
|
||||
has to be read a number of times (max 50).
|
||||
|
||||
After reading CMD, DATA should hold 0x08 which means that the uGuru is ready
|
||||
for input. As above DATA will usually hold 0x08 the first read but not always.
|
||||
This step can be skipped, but it is undetermined what happens if the uGuru has
|
||||
not yet reported 0x08 at DATA and you proceed with writing a bank address.
|
||||
|
||||
|
||||
Sending bank and sensor addresses to the uGuru
|
||||
----------------------------------------------
|
||||
|
||||
First the uGuru must be in "ready" mode as described above, DATA should hold
|
||||
0x08 indicating that the uGuru wants input, in this case the bank address.
|
||||
|
||||
Next write the bank address to DATA. After the bank address has been written
|
||||
wait for to DATA to hold 0x08 again indicating that it wants / is ready for
|
||||
more input (max 250 reads).
|
||||
|
||||
Once DATA holds 0x08 again write the sensor address to CMD.
|
||||
|
||||
|
||||
Reading
|
||||
-------
|
||||
|
||||
First send the bank and sensor addresses as described above.
|
||||
Then for each byte of data you want to read wait for DATA to hold 0x01
|
||||
which indicates that the uGuru is ready to be read (max 250 reads) and once
|
||||
DATA holds 0x01 read the byte from CMD.
|
||||
|
||||
Once all bytes have been read data will hold 0x09, but there is no reason to
|
||||
test for this. Notice that the number of bytes is bank address dependent see
|
||||
above and below.
|
||||
|
||||
After completing a successfull read it is advised to put the uGuru back in
|
||||
ready mode, so that it is ready for the next read / write cycle. This way
|
||||
if your program / driver is unloaded and later loaded again the detection
|
||||
algorithm described above will still work.
|
||||
|
||||
|
||||
|
||||
Writing
|
||||
-------
|
||||
|
||||
First send the bank and sensor addresses as described above.
|
||||
Then for each byte of data you want to write wait for DATA to hold 0x00
|
||||
which indicates that the uGuru is ready to be written (max 250 reads) and
|
||||
once DATA holds 0x00 write the byte to CMD.
|
||||
|
||||
Once all bytes have been written wait for DATA to hold 0x01 (max 250 reads)
|
||||
don't ask why this is the way it is.
|
||||
|
||||
Once DATA holds 0x01 read CMD it should hold 0xAC now.
|
||||
|
||||
After completing a successfull write it is advised to put the uGuru back in
|
||||
ready mode, so that it is ready for the next read / write cycle. This way
|
||||
if your program / driver is unloaded and later loaded again the detection
|
||||
algorithm described above will still work.
|
||||
|
||||
|
||||
Gotchas
|
||||
-------
|
||||
|
||||
After wider testing of the Linux kernel driver some variants of the uGuru have
|
||||
turned up which do not hold 0x08 at DATA within 250 reads after writing the
|
||||
bank address. With these versions this happens quite frequent, using larger
|
||||
timeouts doesn't help, they just go offline for a second or 2, doing some
|
||||
internal callibration or whatever. Your code should be prepared to handle
|
||||
this and in case of no response in this specific case just goto sleep for a
|
||||
while and then retry.

||||

Address Map
|
||||
===========
|
||||
|
||||
Bank 0x20 Alarms (R)
|
||||
--------------------
|
||||
This bank contains 0 sensors, iow the sensor address is ignored (but must be
|
||||
written) just use 0. Bank 0x20 contains 3 bytes:
|
||||
|
||||
Byte 0:
|
||||
This byte holds the alarm flags for sensor 0-7 of Sensor Bank1, with bit 0
|
||||
corresponding to sensor 0, 1 to 1, etc.
|
||||
|
||||
Byte 1:
|
||||
This byte holds the alarm flags for sensor 8-15 of Sensor Bank1, with bit 0
|
||||
corresponding to sensor 8, 1 to 9, etc.
|
||||
|
||||
Byte 2:
|
||||
This byte holds the alarm flags for sensor 0-5 of Sensor Bank2, with bit 0
|
||||
corresponding to sensor 0, 1 to 1, etc.
|
||||
|
||||
|
||||
Bank 0x21 Sensor Bank1 Values / Readings (R)
|
||||
--------------------------------------------
|
||||
This bank contains 16 sensors, for each sensor it contains 1 byte.
|
||||
So far the following sensors are known to be available on all motherboards:
|
||||
Sensor 0 CPU temp
|
||||
Sensor 1 SYS temp
|
||||
Sensor 3 CPU core volt
|
||||
Sensor 4 DDR volt
|
||||
Sensor 10 DDR Vtt volt
|
||||
Sensor 15 PWM temp
|
||||
|
||||
Byte 0:
|
||||
This byte holds the reading from the sensor. Sensors in Bank1 can be both
|
||||
volt and temp sensors, this is motherboard specific. The uGuru however does
|
||||
seem to know (be programmed with) what kindoff sensor is attached see Sensor
|
||||
Bank1 Settings description.
|
||||
|
||||
Volt sensors use a linear scale, a reading 0 corresponds with 0 volt and a
|
||||
reading of 255 with 3494 mV. The sensors for higher voltages however are
|
||||
connected through a division circuit. The currently known division circuits
|
||||
in use result in ranges of: 0-4361mV, 0-6248mV or 0-14510mV. 3.3 volt sources
|
||||
use the 0-4361mV range, 5 volt the 0-6248mV and 12 volt the 0-14510mV .
|
||||
|
||||
Temp sensors also use a linear scale, a reading of 0 corresponds with 0 degree
|
||||
Celsius and a reading of 255 with a reading of 255 degrees Celsius.
|
||||
|
||||
|
||||
Bank 0x22 Sensor Bank1 Settings (R)

|
||||
-----------------------------------
|
||||
|
||||
This bank contains 16 sensors, for each sensor it contains 3 bytes. Each
|
||||
set of 3 bytes contains the settings for the sensor with the same sensor
|
||||
address in Bank 0x21 .
|
||||

Warning for the adventerous
|
||||
===========================
|
||||
|
||||
A word of caution to those who want to experiment and see if they can figure
|
||||
the voltage / clock programming out, I tried reading and only reading banks
|
||||
0-0x30 with the reading code used for the sensor banks (0x20-0x28) and this
|
||||
resulted in a _permanent_ reprogramming of the voltages, luckily I had the
|
||||
sensors part configured so that it would shutdown my system on any out of spec
|
||||
voltages which proprably safed my computer (after a reboot I managed to
|
||||
immediatly enter the bios and reload the defaults). This probably means that
|
||||
the read/write cycle for the non sensor part is different from the sensor part.

Description
|

-----------
|
||||
|
||||
This driver implements support for the National Semiconductor LM70
|
||||
temperature sensor.
|
||||
|
||||
The LM70 temperature sensor chip supports a single temperature sensor.
|
||||
It communicates with a host processor (or microcontroller) via an
|
||||
SPI/Microwire Bus interface.
|
||||
|
||||
Communication with the LM70 is simple: when the temperature is to be sensed,
|
||||
the driver accesses the LM70 using SPI communication: 16 SCLK cycles
|
||||
comprise the MOSI/MISO loop. At the end of the transfer, the 11-bit 2's
|
||||
complement digital temperature (sent via the SIO line), is available in the
|
||||
driver for interpretation. This driver makes use of the kernel's in-core
|
||||
SPI support.

Description
|
||||
-----------
|
||||
|
||||
This driver implements support for the hardware sensor capabilities
|
||||
of the SMSC LPC47M192 and LPC47M997 Super-I/O chips.
|
||||
|
||||
These chips support 3 temperature channels and 8 voltage inputs
|
||||
as well as CPU voltage VID input.
|
||||
|
||||
They do also have fan monitoring and control capabilities, but the
|
||||
these features are accessed via ISA bus and are not supported by this
|
||||
driver. Use the 'smsc47m1' driver for fan monitoring and control.
|
||||
|
||||
Voltages and temperatures are measured by an 8-bit ADC, the resolution
|
||||
of the temperatures is 1 bit per degree C.
|
||||
Voltages are scaled such that the nominal voltage corresponds to
|
||||
192 counts, i.e. 3/4 of the full range. Thus the available range for
|
||||
each voltage channel is 0V ... 255/192*(nominal voltage), the resolution
|
||||
is 1 bit per (nominal voltage)/192.
|
||||
Both voltage and temperature values are scaled by 1000, the sys files
|
||||
show voltages in mV and temperatures in units of 0.001 degC.
|
||||
|
||||
The +12V analog voltage input channel (in4_input) is multiplexed with
|
||||
bit 4 of the encoded CPU voltage. This means that you either get
|
||||
a +12V voltage measurement or a 5 bit CPU VID, but not both.
|
||||
The default setting is to use the pin as 12V input, and use only 4 bit VID.
|
||||
This driver assumes that the information in the configuration register
|
||||
is correct, i.e. that the BIOS has updated the configuration if
|
||||
the motherboard has this input wired to VID4.
|
||||
|
||||
The temperature and voltage readings are updated once every 1.5 seconds.
|
||||
Reading them more often repeats the same values.

in4_input - +12V voltage input (may be missing if used as VID4)

All voltages are read and written in mV.
|
||||
|
||||
in[0-7]_alarm - alarm flags for voltage inputs
|
||||
These files read '1' in case of alarm, '0' otherwise.
|
||||
|
||||
temp1_input - chip temperature measured by on-chip diode
|
||||
temp[2-3]_input - temperature measured by external diodes (one of these would
|
||||
typically be wired to the diode inside the CPU)
|

||||
temp[1-3]_min,
|
||||
temp[1-3]_max - lower and upper alarm thresholds for temperatures
|
||||
|
||||
temp[1-3]_offset - temperature offset registers
|
||||
The chip adds the offsets stored in these registers to
|
||||
the corresponding temperature readings.
|
||||
Note that temp1 and temp2 offsets share the same register,
|
||||
they cannot both be different from zero at the same time.
|
||||
Writing a non-zero number to one of them will reset the other
|
||||
offset to zero.
|
||||
|
||||
All temperatures and offsets are read and written in
|
||||
units of 0.001 degC.
|
||||
|
||||
temp[1-3]_alarm - alarm flags for temperature inputs, '1' in case of alarm,
|
||||
'0' otherwise.
|
||||
temp[2-3]_input_fault - diode fault flags for temperature inputs 2 and 3.
|
||||
A fault is detected if the two pins for the corresponding
|
||||
sensor are open or shorted, or any of the two is shorted
|
||||
to ground or Vcc. '1' indicates a diode fault.
|
||||
|
||||
cpu0_vid - CPU voltage as received from the CPU

vrm - CPU VID standard used for decoding CPU voltage

Kernel driver w83791d
|
||||
=====================
|
||||
|
||||
Supported chips:
|
||||
* Winbond W83791D
|
||||
Prefix: 'w83791d'
|
||||
Addresses scanned: I2C 0x2c - 0x2f
|
||||
Datasheet: http://www.winbond-usa.com/products/winbond_products/pdfs/PCIC/W83791Da.pdf
|
||||
|
||||
Author: Charles Spirakis <bezaur@gmail.com>
|
||||
|
||||
This driver was derived from the w83781d.c and w83792d.c source files.

Module Parameters
|
||||
-----------------
|
||||
|
||||
* init boolean
|
||||
(default 0)
|
||||
Use 'init=1' to have the driver do extra software initializations.
|
||||
The default behavior is to do the minimum initialization possible
|
||||
and depend on the BIOS to properly setup the chip. If you know you
|
||||
have a w83791d and you're having problems, try init=1 before trying
|
||||
reset=1.
|
||||
|
||||
* reset boolean
|
||||
(default 0)
|
||||
Use 'reset=1' to reset the chip (via index 0x40, bit 7). The default
|
||||
behavior is no chip reset to preserve BIOS settings.
|
||||
|
||||
* 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 W83791D chip.
|
||||
|
||||
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, five fan rotation speed
|
||||
sensors, and ten voltage sensors.
|
||||
|
||||
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 for fan 1/2/3
|
||||
and 1, 2, 4, 8, 16, 32, 64 or 128 for fan 4/5) 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 a "realtime status register". The
|
||||
following bits are defined:
|
||||
|
||||
bit - alarm on:
|
||||
0 - Vcore
|
||||
1 - VINR0
|
||||
2 - +3.3VIN

||||

|
||||

|
||||

||||

|
||||
21 - fan4
|
||||
22 - fan5
|
||||
23 - reserved
|
||||
|
||||
When an alarm goes off, you can be warned by a beeping signal through your
|
||||
computer speaker. It is possible to enable all beeping globally, or only
|
||||
the beeping for some alarms.
|
||||
|
||||
The driver only reads the chip values each 3 seconds; reading them more
|
||||
often will do no harm, but will return 'old' values.

i2c-ocores is an i2c bus driver for the OpenCores.org I2C controller
|
||||
IP core by Richard Herveille.
|
||||
|
||||
Usage
|
||||
-----
|
||||
|
||||
i2c-ocores uses the platform bus, so you need to provide a struct
|
||||
platform_device with the base address and interrupt number. The
|
||||
dev.platform_data of the device should also point to a struct
|
||||
ocores_i2c_platform_data (see linux/i2c-ocores.h) describing the
|
||||
distance between registers and the input clock speed.
|
||||
|
||||
E.G. something like:
|
||||
|
||||
static struct resource ocores_resources[] = {
|
||||
[0] = {
|
||||
.start = MYI2C_BASEADDR,
|
||||
.end = MYI2C_BASEADDR + 8,
|
||||
.flags = IORESOURCE_MEM,
|
||||
},
|
||||
[1] = {
|
||||
.start = MYI2C_IRQ,
|
||||
.end = MYI2C_IRQ,
|
||||
.flags = IORESOURCE_IRQ,
|
||||
},
|
||||
};
|
||||
|
||||
static struct ocores_i2c_platform_data myi2c_data = {
|
||||
.regstep = 2, /* two bytes between registers */
|
||||
.clock_khz = 50000, /* input clock of 50MHz */
|
||||
};
|
||||
|
||||
static struct platform_device myi2c = {
|
||||
.name = "ocores-i2c",
|
||||
.dev = {
|
||||
.platform_data = &myi2c_data,
|
||||
},
|
||||
.num_resources = ARRAY_SIZE(ocores_resources),
|
||||
.resource = ocores_resources,

};

A few OSB4 southbridges are known to be misconfigured by the BIOS. In this
|

case, you have you use the fix_hstcfg module parameter. Do not use it
|

unless you know you have to, because in some cases it also breaks
|
||||
configuration on southbridges that don't need it.
|
||||
If you own Force CPCI735 motherboard or other OSB4 based systems you may need
|
||||
to change the SMBus Interrupt Select register so the SMBus controller uses
|
||||
the SMI mode.
|
||||
|
||||
1) Use lspci command and locate the PCI device with the SMBus controller:
|
||||
00:0f.0 ISA bridge: ServerWorks OSB4 South Bridge (rev 4f)
|
||||
The line may vary for different chipsets. Please consult the driver source
|
||||
for all possible PCI ids (and lspci -n to match them). Lets assume the
|
||||
device is located at 00:0f.0.
|
||||
2) Now you just need to change the value in 0xD2 register. Get it first with
|
||||
command: lspci -xxx -s 00:0f.0
|
||||
If the value is 0x3 then you need to change it to 0x1
|
||||
setpci -s 00:0f.0 d2.b=1
|
||||
|
||||
Please note that you don't need to do that in all cases, just when the SMBus is
|
||||
not working properly.

|
||||
Hardware-specific issues
|
||||
------------------------
|
||||
|
||||
This driver will refuse to load on IBM systems with an Intel PIIX4 SMBus.
|
||||
Some of these machines have an RFID EEPROM (24RF08) connected to the SMBus,
|
||||
which can easily get corrupted due to a state machine bug. These are mostly
|
||||
Thinkpad laptops, but desktop systems may also be affected. We have no list
|
||||
of all affected systems, so the only safe solution was to prevent access to
|
||||
the SMBus on all IBM systems (detected using DMI data.)
