We don't play with it anyway. - -Authors: - Chen-Yuan Wu <gwu@esoft.com>, - Jean Delvare <jdelvare@suse.de> - -Description ------------ - -(This is from Analog Devices.) The ADM1025 is a complete system hardware -monitor for microprocessor-based systems, providing measurement and limit -comparison of various system parameters. Five voltage measurement inputs -are provided, for monitoring +2.5V, +3.3V, +5V and +12V power supplies and -the processor core voltage. The ADM1025 can monitor a sixth power-supply -voltage by measuring its own VCC. One input (two pins) is dedicated to a -remote temperature-sensing diode and an on-chip temperature sensor allows -ambient temperature to be monitored. - -One specificity of this chip is that the pin 11 can be hardwired in two -different manners. It can act as the +12V power-supply voltage analog -input, or as the a fifth digital entry for the VID reading (bit 4). It's -kind of strange since both are useful, and the reason for designing the -chip that way is obscure at least to me. The bit 5 of the configuration -register can be used to define how the chip is hardwired. Please note that -it is not a choice you have to make as the user. The choice was already -made by your motherboard's maker. If the configuration bit isn't set -properly, you'll have a wrong +12V reading or a wrong VID reading. The way -the driver handles that is to preserve this bit through the initialization -process, assuming that the BIOS set it up properly beforehand. If it turns -out not to be true in some cases, we'll provide a module parameter to force -modes. - -This driver also supports the ADM1025A, which differs from the ADM1025 -only in that it has "open-drain VID inputs while the ADM1025 has on-chip -100k pull-ups on the VID inputs". It doesn't make any difference for us. |
