.Dd December 11, 2015 .Dt ADM1026HM 4 .Os .Sh NAME .Nm adm1026hm .Nd Analog Devices ADM1026 complete thermal system management controller .Sh SYNOPSIS .Cd "adm1026hm* at iic0 addr 0x2e: ADM1026 hardware monitor: rev. 0x4, step. 0x5" .Cd "adm1026hm*: 8 fans, 3 temperatures, 15 voltages" .Sh DESCRIPTION The .Nm driver provides support for the Analog Devices ADM1026 hardware monitor. The chip possesses 8 fan speed sensors, 3 temperature sensors, and 17 voltage sensors. The number of each sensor type configured by the driver depends on the chip configuration.
p The values of the sensors are made available through the .Xr envstat 8 interface. l -column "V3.3 standby" "uV DC" "Description" -offset indent t Sy "Sensor" Ta Sy "Units" Ta Sy "Description" t Li "fan N" Ta "RPM" Ta "Fan 0-7" t Li "internal" Ta "C" Ta "Internal temperature" t Li "external N" Ta "C" Ta "External temperature 1\(en2" t Li "Vbatt" Ta "mV DC" Ta "Battery voltage" t Li "V3.3 standby" Ta "mV DC" Ta "3.3V standby voltage" t Li "V3.3 main" Ta "mV DC" Ta "3.3V main voltage" t Li "V5.0" Ta "mV DC" Ta "5.0V supply voltage" t Li "V+12" Ta "mV DC" Ta "+12V supply voltage" t Li "V-12" Ta "mV DC" Ta "-12V supply voltage" t Li "V3.3 N" Ta "mV DC" Ta "Analog in (3.3V reference) 0\(en5" t Li "V2.5 N" Ta "mV DC" Ta "Analog in (2.5V reference) 0\(en3" .El .Sh SEE ALSO .Xr iic 4 , .Xr intro 4 , .Xr envstat 8 .Sh AUTHORS .An -nosplit The .Nm driver was written by .An Julian Coleman Aq Mt jcoleman@NetBSD.org . .Sh BUGS It's not possible to determine if either a sensor is not connected, or the monitored device is producing no output. Therefore, unconnected sensors will show outputs of 0.
p The .Nm driver does not support checking or altering limit values, interrupt output, nor the built-in EEPROM.
