| 9 | OVERVIEW OF THE LM_SENSORS PACKAGE AND SUMMARY OF SUPPORTED DEVICES |
|---|
| 10 | |
|---|
| 11 | !!! This package is ONLY for 2.6, 2.5, and 2.4 kernels (2.4.10 or later) !!! |
|---|
| 12 | !!! THIS PACKAGE REQUIRES i2c-2.9.0 or later!!! |
|---|
| 13 | |
|---|
| 14 | FOR 2.6/2.5 KERNELS, use only the userspace tools in this package! |
|---|
| 15 | Build and install them with 'make user' and 'make user_install'. |
|---|
| 16 | The kernel modules in this package will not compile for 2.6/2.5; |
|---|
| 17 | use the drivers already in the 2.6 kernel. |
|---|
| 18 | |
|---|
| 19 | ============================================================================= |
|---|
| 20 | |
|---|
| 21 | This is the completely rewritten version 2 of lm_sensors, a collection of |
|---|
| 22 | modules for general SMBus[1] access and hardware monitoring. |
|---|
| 23 | Version 1 is now officially unsupported. |
|---|
| 24 | |
|---|
| 25 | WARNING! The drivers in this package will work on reasonably recent 2.4 |
|---|
| 26 | kernels only (2.4.10 and later). |
|---|
| 27 | Use lm_sensors-2.4.5 for 2.0 kernels. |
|---|
| 28 | Use lm_sensors-2.7.0 for 2.2, 2.3, and 2.4.0 - 2.4.9 kernels. |
|---|
| 29 | Use the drivers already in the kernel for 2.6/2.5 kernels; if you need |
|---|
| 30 | additional drivers in 2.6 please port and submit them to us. |
|---|
| 31 | |
|---|
| 32 | HOWEVER, the userspace tools in this package will work for |
|---|
| 33 | 2.4, 2.5, and 2.6 kernels. |
|---|
| 34 | |
|---|
| 35 | WARNING! You must have at least i2c-2.9.0. |
|---|
| 36 | EVEN IF your kernel does contain i2c support! |
|---|
| 37 | |
|---|
| 38 | The I2C[2] package in existing 2.4 kernels is NOT sufficient |
|---|
| 39 | for compilation of this package. |
|---|
| 40 | |
|---|
| 41 | ADDITIONALLY, i2c-2.9.0 is API compatible to i2c releases 2.7.0 and earlier, |
|---|
| 42 | but is not API compatible to i2c releases 2.8.0 - 2.8.8 |
|---|
| 43 | due to struct changes. Versions 2.8.x of i2c are considered deprecated. |
|---|
| 44 | |
|---|
| 45 | See the lm_sensors download page for further guidance: |
|---|
| 46 | http://www.lm-sensors.org/wiki/Download |
|---|
| 47 | |
|---|
| 48 | |
|---|
| 49 | WARNING! If you downloaded this package through our SVN archive, you walk |
|---|
| 50 | the cutting edge. Things may not even compile! On the other hand, you will |
|---|
| 51 | be the first to profit from new drivers and other changes. Have fun! |
|---|

| 116 | The list above may be out of date; |
|---|
| 117 | see our New Drivers page at http://www.lm-sensors.org/wiki/NewDrivers |
|---|
| 118 | for the latest information on supported devices. |
|---|
| 119 | You may also refer to doc/chips/SUMMARY for details on what each chip |
|---|
| 120 | can monitor. |
|---|
| 121 | |
|---|
| 122 | |
|---|
| 123 | We always appreciate testers. If you own a specific monitoring chip listed |
|---|
| 124 | on our 'new drivers' page, and are willing to help us out, please contact |
|---|
| 125 | us. Even if you have no programming knowledge, you could help us by running |
|---|
| 126 | new modules and reporting on the results and output. If you want to offer |
|---|
| 127 | more substantial help, this is very welcome too, of course. |
|---|
| 128 | |
|---|
| 129 | |
|---|
| 130 | Don't ask us whether we support a particular mainboard; we do not know. |
|---|
| 131 | We *do* know what hardware we support, but usually, it is easier to |
|---|
| 132 | install everything and run sensors-detect. It will tell you what hardware |
|---|
| 133 | you have (and incidentally, what corresponding drivers are needed). You |
|---|
| 134 | could also take a look at http://mbm.livewiredev.com/ |
|---|
| 135 | (this lists chips found on many mainboard, but regrettably not the adapters |
|---|
| 136 | on them) or http://web01.fureai.or.jp/~hirobo/project/reserch_project.html |
|---|
| 137 | (yes, it is Japanese; you want the ninth column, and it again lists only |
|---|
| 138 | chips, not adapters). |
|---|
| 139 | |
|---|
| 140 | |
|---|
| 141 | SMBus, also known as System Management Bus, is a protocol for communicating |
|---|
| 142 | through a I2C ('I squared C') bus. Many modern mainboards have a System |
|---|
| 143 | Management Bus. There are a lot of devices which can be connected to a |
|---|
| 144 | SMBus; the most notable are modern memory chips with EEPROM memories and |
|---|
| 145 | chips for hardware monitoring. |
|---|
| 146 | |
|---|
| 147 | Most modern mainboards incorporate some form of hardware monitoring chips. |
|---|
| 148 | These chips read things like chip temperatures, fan rotation speeds and |
|---|
| 149 | voltage levels. There are quite a few different chips which can be used by |
|---|
| 150 | mainboard builders for approximately the same results. |
|---|
| 151 | |
|---|
| 152 | Hardware monitoring chips often have an SMBus or I2C interface. Some are |
|---|
| 153 | connected to ISA bus instead. Some of them can do both, in which case we |
|---|
| 154 | either support both access methods (old drivers) or only support ISA |
|---|
| 155 | access (new drivers) as it is faster. |
|---|
| 156 | |
|---|
| 157 | Because the SMBus is just a special case of the generalized I2C bus, we can |
|---|
| 158 | simulate the SMBus protocol on plain I2C busses. These busses are sometimes |
|---|
| 159 | used in other parts of your computer. If a supported chip is attached to |
|---|
| 160 | one of these additional busses, they can be used too. |
|---|
| 161 | |
|---|
| 162 | Please read INSTALL before trying to compile and install these modules. |
|---|
| 163 | There is a lot of additional documentation in the doc/ subdirectory. |
|---|
| 164 | Amnong these is a list of supported busses and chips. Regrettably, there |
|---|
| 165 | are too many mainboards to keep a list of busses and chips used on them. |
|---|
| 166 | On the other hand, we provide a program called 'sensors-detect' which |
|---|
| 167 | tries to figure out what hardware is available on your system. |
|---|
| 168 | |
|---|
| 169 | The developers of this package can be reached through a mailing-list |
|---|
| 170 | (see http://www.lm-sensors.org/wiki/AuthorsAndContributors). Do not hesitate |
|---|
| 171 | to mail us if you have questions, suggestions, problems, want to |
|---|
| 172 | contribute, or just want to report it works for you. But please try to |
|---|
| 173 | read the documentation and FAQ before you ask any questions! |
|---|
| 174 | |
|---|
| 175 | The latest version of this package can always be found on our homepage: |
|---|
| 176 | http://www.lm-sensors.org. Pre-release versions can be retrieved |
|---|
| 177 | through anonymous SVN; see doc/svn for details. |
