I think I may have some time for this on thursday evening or weekend. Problem is that I must have physical access to that computer so I can look what a fan is doing ;) If you want to test it please apply this patches: http://lists.lm-sensors.org/pipermail/lm-sensors/2006-January/015115.html Please check my "preliminary - proprietary - confidental - NDA required" comments about the patches ;) Some things are not working as expected some has problems and I remember I had the problem with the fan reglation because the automatic one acted somehow strange... I hope it helps. Please be patient. I'm converting the website to wiki too and I had to review some drivers and this is quite time eater. Regards Rudolf /sys files ---------- pwm[1-4] - this file stores PWM duty cycle or DC value (fan speed) in range: 0 (stop) to 255 (full) pwm[1-4]_enable - this file controls mode of fan/temperature control: our iterface specify 0=disable * 0 Manual mode * 1 Thermal Cruise * 2 Fan Speed Cruise * 3 Smart FAN III pwm[1-4]_mode - Select PWM of DC mode * 0 DC * 1 PWM For Thermal Cruise mode ------------------------ thermal_cruise[1-4] - Selects the desired temperature for cruise (degC) 0-255? -> wrong limit tolerance[1-4] - Value in degrees of Celsius (degC) for +- T limit is 0-15 For Fan speed Cruise mode ------------------------ thermal_cruise[1-4] - Selects desired target speed (limit is 0-255) -> WRONG UNITS USED what unit is it rotations? or ticks??? tolerance[1-4] - tolerance of desired target speed (limit is 0-15) -> WRONG UNITS USED SF3 --- Target SF3 temperature should be written to thermal_cruise, but thermal_cruise2 and thermal_cruise4 is used (regs 0x6 and 0x63) Tolerance of SF3 (0x7 bit-4-7, +cr62) but tolerance2 and tolerance4 is used So this would mean to rename 1->2 and 2->4 to have it sane. /sys/bus/i2c/devices/9191-0290/sf3_fan_max1 255 /sys/bus/i2c/devices/9191-0290/sf3_fan_max2 255 /sys/bus/i2c/devices/9191-0290/sf3_fan_min1 177 /sys/bus/i2c/devices/9191-0290/sf3_fan_min2 1 /sys/bus/i2c/devices/9191-0290/sf3_fan_step1 1 /sys/bus/i2c/devices/9191-0290/sf3_fan_step2 1 /sys/bus/i2c/devices/9191-0290/sf3_step_time_down 1 /sys/bus/i2c/devices/9191-0290/sf3_step_time_up 1 /sys/bus/i2c/devices/9191-0290/sf3_stop_time1 60 /sys/bus/i2c/devices/9191-0290/sf3_stop_time2 60 sf3_fan_max[1-2] ------------------ When at SMART FANTM III mode, CPUFANOUT0 value will increase to this value. This register should be written a non-zero value that cannot lower than Stop value. 0-255 is there right now -> 0 is allowed!!! sf3_fan_min[1-2] ---------------- THIS IS USED ALSO IN THERMAL CRUISE AS BORDER (only for 2 and 4????) 0 is allowed!!! When at Thermal Cruise mode or SMART FAN TM III mode, CPUFANOUT0-1 value will decrease to this value. This register should be written a non-zero minimum stop value. (1)When at PWM output: The unit of this register is 0.1 second. The default time is 6 seconds. (2)When at DC Voltage output: The unit of this register is 0.4 second. The default time is 24 seconds. sf3_step_time_down ------------------- This register determines the speed of FANOUT decreasing its value in Smart Fan Control mode. (1)When at PWM output: The unit of this register is 0.1 second. The default time is 1 seconds. (2)When at DC Voltage output: The unit of this register is 0.4 second. The default time is 4 seconds. sf3_step_time_up ---------------- This register determines the speed of FANOUT increasing the its value in Smart Fan Control mode. (1)When at PWM output: The unit of this register is 0.1 second. The default time is 1 seconds. (2)When at DC Voltage output: The unit of this register is 0.4 second. The default time is 4 seconds. TODO: Also for the thermal cruise and smartfan STOP VALUE reg (0x15 and others should be implemented) and start value??? (0xA)
