The Maxim MAX1617 is -the oldest; it has the problem that it is not very well detectable. The -MAX1617A solves that. The ADM1021 is a straight clone of the MAX1617A. -Ditto for the THMC10. From here on, we will refer to all these chips as -ADM1021-clones. - -The ADM1021 and MAX1617A reports a die code, which is a sort of revision -code. This can help us pinpoint problems; it is not very useful -otherwise. - -ADM1021-clones implement two temperature sensors. One of them is internal, -and measures the temperature of the chip itself; the other is external and -is realised in the form of a transistor-like device. A special alarm -indicates whether the remote sensor is connected. - -Each sensor has its own low and high limits. When they are crossed, the -corresponding alarm is set and remains on as long as the temperature stays -out of range. Temperatures are measured in degrees Celsius. Measurements -are possible between -65 and +127 degrees, with a resolution of one degree. - -If an alarm triggers, it will remain triggered until the hardware register -is read at least once. This means that the cause for the alarm may already -have disappeared! - -This driver only updates its values each 1.5 seconds; reading it more often -will do no harm, but will return 'old' values. It is possible to make -ADM1021-clones do faster measurements, but there is really no good reason -for that. - - -Netburst-based Xeon support ---------------------------- - -Some Xeon processors based on the Netburst (early Pentium 4, from 2001 to -2003) microarchitecture had real MAX1617, ADM1021, or compatible chips -within them, with two temperature sensors. Other Xeon processors of this -era (with 400 MHz FSB) had chips with only one temperature sensor. - -If you have such an old Xeon, and you get two valid temperatures when -loading the adm1021 module, then things are good. - -If nothing happens when loading the adm1021 module, and you are certain -that your specific Xeon processor model includes compatible sensors, you -will have to explicitly instantiate the sensor chips from user-space. See -method 4 in Documentation/i2c/instantiating-devices.rst. Possible slave -addresses are 0x18, 0x1a, 0x29, 0x2b, 0x4c, or 0x4e. It is likely that -only temp2 will be correct and temp1 will have to be ignored. - -Previous generations of the Xeon processor (based on Pentium II/III) -didn't have these sensors. Next generations of Xeon processors (533 MHz -FSB and faster) lost them, until the Core-based generation which -introduced integrated digital thermal sensors. These are supported by -the coretemp driver. diff --git a/Documentation/hwmon/amc6821.rst b/Documentation/hwmon/amc6821.rst index 5ddb2849da90..dbd544cd1160 100644 --- a/Documentation/hwmon/amc6821.rst +++ b/Documentation/hwmon/amc6821.rst @@ -47,13 +47,18 @@ fan1_input ro tachometer speed fan1_min rw " fan1_max rw " fan1_fault ro " -fan1_div rw Fan divisor can be either 2 or 4. +fan1_pulses rw Pulses per revolution can be either 2 or 4. +fan1_target rw Target fan speed, to be used with pwm1_enable + mode 4. pwm1 rw pwm1 pwm1_enable rw regulator mode, 1=open loop, 2=fan controlled by remote temperature, 3=fan controlled by combination of the on-chip temperature and remote-sensor temperature, + 4=fan controlled by target rpm set with + fan1_target attribute. +pwm1_mode rw Fan duty control mode (0=DC, 1=PWM) pwm1_auto_channels_temp ro 1 if pwm_enable==2, 3 if pwm_enable==3 pwm1_auto_point1_pwm ro Hardwired to 0, shared for both temperature channels. diff --git a/Documentation/hwmon/asus_ec_sensors.rst b/Documentation/hwmon/asus_ec_sensors.rst index 0bf99ba406dd..ca38922f4ec5 100644 --- a/Documentation/hwmon/asus_ec_sensors.rst +++ b/Documentation/hwmon/asus_ec_sensors.rst @@ -8,6 +8,7 @@ Supported boards: * PRIME X570-PRO * Pro WS X570-ACE * ProArt X570-CREATOR WIFI + * ProArt X670E-CREATOR WIFI * ProArt B550-CREATOR * ROG CROSSHAIR VIII DARK HERO * ROG CROSSHAIR VIII HERO (WI-FI) diff --git a/Documentation/hwmon/corsair-cpro.rst b/Documentation/hwmon/corsair-cpro.rst index 751f95476b57..15077203a2f8 100644 --- a/Documentation/hwmon/corsair-cpro.rst +++ b/Documentation/hwmon/corsair-cpro.rst @@ -39,3 +39,11 @@ fan[1-6]_target Sets fan speed target rpm. pwm[1-6] Sets the fan speed.
