Until then, don't blindly trust what you read here. - -================================== -SUMMARY - - [modprobe,insmod] module {parameter...} - Parameters: - force=bus,address{,bus,address} - force_addr=address{,address} - force_[chipname]=bus,address{,bus,address} - force_subclients=bus,caddr,saddr,saddr - ignore=bus,address{,bus,address} - ignore_range=bus,start,end{,bus,start,end} - probe=bus,address{,bus,address} - probe_range=bus,start,end{,bus,start,end} - init=[0,1] (default 1) - - All arguments are in decimal unless prefixed by "0x". - No spaces are allowed. - -================================== -OVERVIEW - -All chip drivers have a few modprobe module parameters in common. -(Insmod can also be used, but we recommend modprobe so that -other required modules are automatically loaded.) These -parameters can be used when a module is inserted, to give some additional -information about how it should function. In this case, they tell where -the module should look for what chips. Usually, you don't need them, and -if you do, you are often told by sensors-detect which ones you need. - -If a module doesn't load with no parameters, you may need to -add parameters. Check 'dmesg' for clues to what went wrong. - - -BUS NUMBERING -------------- -I2C/SMBus adapters are numbered in the order they are inserted. If you want -to know what number an adapter has, use the following command: - - (for kernel 2.6.32 and newer) - grep . /sys/bus/i2c/devices/i2c-*/name - - (for kernel 2.6.31 and older) - grep . /sys/class/i2c-adapter/i2c-*/name - -Alternatively, if you have installed i2c-tools, you can do: - - modprobe i2c-dev - i2cdetect -l - -If you want 'any I2C bus', use '-1'. - - -ADDRESS NUMBERING ------------------ -Each adapter has a number of addresses on I2C/SMBus adapters and/or the -ISA bus that are always scanned if no modprobe parameters are given. The -parameters below override those addresses that are scanned by default. - -All modprobe parameters described below take lists of positive integers -(unsigned, in the range of 0 to 65535) as their arguments. Integers -are separated by comma's, and may be given as ordinary decimal numbers, -as octal numbers (by starting them with a `0') or as hexadecimal numbers -(by starting them with a `0x'). More information can be found by -entering `man modprobe' or `man insmod'. -So to summarize: - 0x00 - 0x7f Valid I2C Addresses - 0x0000 - 0xffff Valid ISA Bus Addresses - - -================================== -PARAMETER DETAILS - -`force', `force_*', `ignore' and `probe' parameters take pairs of numbers. -Each first (odd) number is a bus number, each second (even) number is -an (I2C or ISA) address. - -`ignore_range' and `probe_range' parameters take triples of numbers. -Each first number is a bus number, each second number is the start address -of a range, and each third number is the end address of a range. Ranges -are always inclusive. - -`probe' and `probe_range' parameters tell the module to scan additional -addresses for a specific bus. These are treated just as the ordinary -addresses scanned. This is useful for some chips that can be anywhere; -to keep loading time (and false detections) down, only the most common -addresses are scanned by default. - -`ignore' and `ignore_range' parameters tell the module not to scan -specific addresses. They overrule the default addresses and any -addresses specified by `probe' and `probe_range' statements. - -The `force' parameter tells the module a supported chip is found at -a specific address. It overrules all previously mentioned parameters. -Sometimes, a chip can be in a specific internal state that makes -detection impossible. If you specify it with the `force' parameter, -it is first put into a recognizable state. Also, some detection routines -are skipped. If the module supports several chips, it will still try -to determine what chip is found on that address. If it can't determine -this, the address will still not be used. - -There is a `force_*' parameter for each type of chip supported by a -module. This is the strongest statement possible - it says that a -specific type of chip is found on a specific address, and the module -will skip all detection and recognition routines. This can lead to -very strange results... - -`force_addr' is a parameter used for PCI sensor adapters. -It is used to program the base address of the sensor registers. -This is required if the BIOS does not initialize the base address. - -`force_subclients' is used to force the i2c addresses for subclients of -a certain chip. Typical usage is `force_subclients=0,0x2d,0x4a,0x4b' -to force the subclients of chip 0x2d on bus 0 to i2c addresses -0x4a and 0x4b. -This parameter is currently supported only by the w83781d driver -and is useful for certain Tyan boards. - -`init' is used to tell a driver to bypass initializing a chip. -This may be necessary if the BIOS has initialized the chip a certain way -and the driver should not overwrite that initialization. -It is also useful if normal initialization crashes the system. -The default is 1, so the only useful value is `init=0'. -This parameter is currently supported only by the w83781d driver. - -================================== -EXAMPLE - - # ISA address 0x390 contains a LM79 - # Scan all I2C addresses (from 0 to 0x7f) for all I2C adapters - # But skip address 0x2d on adapter 0, and address 0x20 on adapter 1 - - modprobe lm78 force_lm79=9191,0x390 ignore=0,0x2d,1,0x20 probe_range=-1,0,0x7f |
