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. + +I2C/SMBus adapters are numbered in the order they are inserted. If you want +to know what number an adapter has, please make sure module `i2c-proc' is +inserted, and look at file /proc/bus/i2c. The ISA bus always has the +symbolic number 9191 (`I' is the ninth letter of the alphabet, `S' the +nineteenth and `A' the first). If you want 'any I2C bus', use '-1' +(or 65535). + +Each adapter has a number of addresses on I2C/SMBus adapters and/or the +ISA bus that are always scanned if no insmod parameters are given. The +parameters below override those addresses that are scanned by default. + +All insmod 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 insmod'. + +`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... + +An example: + insmod lm78 force_lm79=9191,0x390 ignore=0,0x2d,1,0x20 probe_range=-1,0,0x7f + # 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 diff --git a/doc/chips/SUMMARY b/doc/chips/SUMMARY index aaa91d51..b6122951 100644 --- a/doc/chips/SUMMARY +++ b/doc/chips/SUMMARY @@ -9,24 +9,31 @@ Driver Chip #temp #vin #fanin pwm/dac i2c ISA adm1021 adm1021 2 - - - yes no max1617 2 - - - yes no + max1617 2 - - - yes no adm9240 adm9240 1 6 5 1 dac yes no ds1780 1 6 5 1 dac yes no gl518sm - gl518smR00 1 1 2 - yes no - gl518smR80 1 4 2 - yes no + gl518sm-r00 1 1/4 2 - yes no + gl518sm-r80 1 4 2 - yes no lm75 lm75 1 - - - yes no lm78 lm78 1 7 3 - yes yes + lm78-j 1 7 3 - yes yes + lm79 1 7 3 - yes yes lm80 lm80 1 7 2 - yes no + +maxilife + maxilife 5 4 3 - yes no + sis5595 sis5595 1 7 3 - no yes
