Hi Mikhail, Sorry for the late answer. I am the (co-)author of the w83795 Linux driver.

Not sure what you mean with "under root". If you meant "as root user", then please no, _never_ build software as root user. Build as a regular user and only install as root. Other than this, yes, "make" as a regular user and "make install" as root should be enough, although you may have to do it again whenever you upgrade your kernel. > 2) Am I right in a pair of "compute" statements for in3 and in4 > values: > > compute in3 @*0.032, @/0.032 > compute in4 @*0.008*6.62, @/0.008/6.62 > > if I base on data supplied by Supermicro (below, they are for 5V and > 12V) ? No. The 0.008 above corresponds to the ADC resolution, and the driver handles it. The only part of the conversion which goes in the configuration file is the external scaling factor. So you want: compute in3 @ * 4, @ / 4 compute in4 @ * 6.62, @ / 6.62 > > ====Supermicro data=================== > Bus Type = SMBus > One W83795AG > > Windbond W83795AG, Slave Address=0x2f (0x5E in 8-Bit format) > ============================================================= > Fan1 Fan Speed, Offset 0x2e RPM = 84375/Data > Fan2 Fan Speed, Offset 0x30 RPM = 84375/Data > Fan3 Fan Speed, Offset 0x35 RPM = 84375/Data > Fan4 Fan Speed, Offset 0x31 RPM = 84375/Data > Fan5 Fan Speed, Offset 0x34 RPM = 84375/Data > Fan6 Fan Speed, Offset 0x32 RPM = 84375/Data > Fan7 Fan Speed, Offset 0x2f RPM = 84375/Data > Fan8 Fan Speed, Offset 0x33 RPM = 84375/Data Apparently the SuperMicro engineers had fun with the fan numbering ;) This can be translated to the following configuration statements: label fan1 "Fan 1" label fan2 "Fan 7" label fan3 "Fan 2" label fan4 "Fan 4" label fan5 "Fan 6" label fan6 "Fan 8" label fan7 "Fan 5" label fan8 "Fan 3" > CPU1 Voltage, Offset 0x11 Voltage = Data* 0.008 > CPU2 Voltage, Offset 0x10 Voltage = Data* 0.008 > +5V Voltage, Offset 0x13 Voltage = Data* 0.008 * (40/10) > +12V Voltage, Offset 0x14 Voltage = Data* 0.008/ (10./66.2) > CPU1 DIMM Voltage, Offset 0x17 Voltage = Data* 0.008 > CPU2 DIMM Voltage, Offset 0x16 Voltage = Data* 0.008 > +1.5V Voltage, Offset 0x12 Voltage = Data* 0.008 No scaling needed except for +5V and +12V, already discussed above. > +3.3V Voltage, Offset 0x1c Voltage = Data* 0.024 > +3.3VSB Voltage, Offset 0x1d Voltage = Data* 0.024 > Battery Voltage, Offset 0x1e Voltage = Data* 0.024 These are already handled by the driver. > CPU1 Temperature, Offset 0x26 Temperature = Data > CPU2 Temperature, Offset 0x27 Temperature = Data > System Temperature, Offset 0x1f Temperature = Data These correspond to temp7, temp8 and temp5, respectively.

I have come up with the following configuration file, please give it a try: http://khali.linux-fr.org/devel/lm-sensors/sensors3-Supermicro-H8DTI.conf -- Jean Delvare http://khali.linux-fr.org/wishlist.html _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
