This is the completely rewritten version of lm_sensors, a collection of |
|---|
| 2 |
modules for general SMBus access and hardware monitoring. There are quite |
|---|
| 3 |
a few changes compared with 1.x.y versions; read doc/version-2 for the |
|---|
| 4 |
most interesting ones. |

WARNING! This is a BETA release. It is not compatible with any programs |
|---|
| 8 |
which are built upon the 1.x.y versions, like wmlm78 or klm. We expect |
|---|
| 9 |
version 2 will soon be supported by them, though. As beta release, there |
|---|
| 10 |
may be problems, and not all version 1 chips are yet supported. Not |
|---|
| 11 |
everything is tested exhaustively, either, often because we simply do |
|---|
| 12 |
not have access to the hardware. Please share your experiences, both |
|---|
| 13 |
good and bad, regarding this package with us at <lm78@stimpy.netroedge.com>. |
|---|
| 14 |
|
|---|
| 15 |
As a rule of thumb: if you have a PIIX4 with LM78/79 and LM75 chips, things |
|---|
| 16 |
should run without problem. The GL518 driver is completely untested. All |
|---|
| 17 |
supporting modules in the src directory should work without problem. If |
|---|
| 18 |
you have a VIA chipset, we would like to hear whether you can access the |
|---|
| 19 |
SMBus with it - this is not very well tested either. If you have a Winbond |
|---|
| 20 |
chip, use the LM78/LM75 drivers until a specific Winbond driver is written. |
|---|
| 21 |
If you have a LM80, you are out of luck at this moment. |
|---|
| 22 |
|
|---|
| 23 |
We expect many updates and new releases the next few weeks (with both bug |
|---|
| 24 |
fixes and new features), so check http://www.netroedge.com/~lm78 (our |
|---|
| 25 |
homepage) often. |
|---|
| 26 |
|
|---|
| 27 |
We could use some testers of hardware. If you own a specific monitoring |
|---|
| 28 |
chip or I2C bus, and are willing to help us out, please contact us - even |
|---|
| 29 |
if you did so before. Even if you have no programming knowledge, you could |
|---|
| 30 |
help us by running new modules and reporting on the results and output. |
|---|
| 31 |
If you want to offer more substantial help, this is very welcome too, of |
|---|
| 32 |
course. We have access to LM78(-J), LM79, LM75, Winbond W83781D and |
|---|
| 33 |
GL518SM chips, and PIIX4 and VIA chipsets. |

SMBus, also known as System Management Bus, is a protocol for communicating |
|---|
| 37 |
through a I2C ('I squared C') bus. Many modern mainboards have a System |
|---|
| 38 |
Management Bus. There are a lot of devices which can be connected to a |
|---|
| 39 |
SMBus; the most notable are modern memory chips with EEPROM memories and |
|---|
| 40 |
chips for hardware monitoring. |
|---|
| 41 |
|
|---|
| 42 |
Most modern mainboards incorporate some form of hardware monitoring chips. |
|---|
| 43 |
These chips read things like chip temperatures, fan rotation speeds and |
|---|
| 44 |
voltage levels. There are quite a few different chips which can be used |
|---|
| 45 |
by mainboard builders for approximately the same results. |
|---|
| 46 |
|
|---|
| 47 |
Hardware monitoring chips are often connected to the SMBus, but often they |
|---|
| 48 |
can also be connected to the ISA bus. The modules in this package usually |
|---|
| 49 |
support both ways of accessing them. |
|---|
| 50 |
|
|---|
| 51 |
Because the SMBus is just a special case of the generalized I2C bus, we |
|---|
| 52 |
can simulate the SMBus protocol on plain I2C busses. These busses are |
|---|
| 53 |
sometimes used in other parts of your computer. If a supported chips is |
|---|
| 54 |
attached to one of these additional busses, they can be used too. |
|---|
| 55 |
|
|---|
| 56 |
Please read INSTALL before trying to compile and install these modules. |
|---|
| 57 |
There is a lot of additional documentation in the doc/ subdirectory. |
|---|
| 58 |
Amnong these is a list of supported busses and chips. Regrettably, there |
|---|
| 59 |
are too many mainboards to keep a list of busses and chips used on them. |
|---|
| 60 |
We will provide a user-space utility which probes for the presence of |
|---|
| 61 |
chips and busses in one of the next releases. |
