The link is wrong. Correct one is <http://lists.lm-sensors.org/pipermail/lm-sensors/2012-November/037694.html>. Experimental support for the ITE IT8603E hardware monitoring features is now available. As a patch at: http://khali.linux-fr.org/devel/linux-3/jdelvare-hwmon/hwmon-it87-01-add-it8603e-support.patch Or as a standalone driver at: http://khali.linux-fr.org/devel/lm-sensors/drivers/it87/ Please test and report. Thanks. It gets detected and shows data on my F2A85-M motherboard with 6404 version EFI firmware: it8603-isa-0290 Adapter: ISA adapter in0: +0.85 V (min = +0.40 V, max = +2.89 V) in1: +1.50 V (min = +1.73 V, max = +2.92 V) ALARM in2: +2.03 V (min = +1.73 V, max = +1.74 V) ALARM in3: +1.99 V (min = +1.73 V, max = +0.84 V) ALARM in4: +1.20 V (min = +2.52 V, max = +2.50 V) ALARM 3VSB: +3.31 V (min = +4.99 V, max = +3.74 V) ALARM Vbat: +3.19 V +3.3V: +3.41 V fan1: 1814 RPM (min = 200 RPM) fan2: 1280 RPM (min = 200 RPM) temp1: +41.0°C (low = -123.0°C, high = +0.0°C) ALARM sensor = thermistor temp2: +34.0°C (low = +96.0°C, high = +52.0°C) sensor = thermistor temp3: -128.0°C (low = +24.0°C, high = -80.0°C) sensor = thermistor intrusion0: OK I guess the alarm boundaries come from user space. Because some of the values are inverted or simply wrong. Yes, the limits are uninitialized and must be set from user-space. You'll have to figure out the voltage mapping first though. See my guide for how you could do that: http://www.lm-sensors.org/wiki/VoltageLabelsAndScaling in0 is most certainly Vcore. in1 could be Vddr3. in2 and in3 must be +5V and +12V or the other way around - follow the guide to figure it out. in4 I don't know, maybe your BIOS will tell. Note that you can add an ignore statement for temp3 as it's clearly not connected. This is visibly solved in Linux 4.9: $ sensors it8603-isa-0290 it8603-isa-0290 Adapter: ISA adapter in0: +1.25 V (min = +0.52 V, max = +2.71 V) in1: +1.50 V (min = +2.15 V, max = +1.02 V) ALARM in2: +1.99 V (min = +1.09 V, max = +1.21 V) ALARM in3: +2.05 V (min = +0.92 V, max = +0.72 V) ALARM in4: +1.20 V (min = +1.92 V, max = +2.38 V) ALARM 3VSB: +3.31 V (min = +1.97 V, max = +2.50 V) ALARM Vbat: +3.22 V +3.3V: +3.29 V fan1: 2220 RPM (min = 200 RPM) fan2: 1011 RPM (min = 600 RPM) temp1: +46.0°C (low = -54.0°C, high = -78.0°C) ALARM sensor = thermistor temp2: +33.0°C (low = +31.0°C, high = -95.0°C) ALARM sensor = thermistor temp3: -128.0°C (low = -123.0°C, high = +116.0°C) sensor = thermistor intrusion0: OK chealer@vinci:~/Téléchargements$ uname -a Linux vinci 4.9.0-3-amd64 #1 SMP Debian 4.9.30-2+deb9u2 (2017-06-26) x86_64 GNU/Linux chealer@vinci:~/Téléchargements$ And visibly, temp3 is not relevant as indicated in Comment #4. And this was visibly already solved in Linux 3.16 (Debian 8). |
The ability to read temperature sensors from ITE's 8603 Super I/O chip would be greatly appreciated for the ASUS F2A85-M motherboard. Currently, lm-sensors fails to detect the board's sensors: Trying family `ITE'... Yes Found unknown chip with ID 0x8603 (logical device 4 has address 0x290, could be sensors) Unfortunately, ITE didn't provide specifications despite a request from Rudolf Marek. In fact, ITE doesn't even acknowledge the existence of that chip. The situation is similar to IT8771E. A patch against lm-sensors was written: http://lists.lm-sensors.org/pipermail/lm-sensors/2012-November/037753.html David Hubbard provided a Linux patch for it87 later in that thread (continuing in December) providing experimental support, which I didn't test. The BIOS from ASUS displays CPU temperature. Contacting ASUS and letting them know that some of their users go beyond their flashy BIOS might be the only way to get specifications (but that didn't work or wasn't attempted in IT8771E's case).
