Hi, Short self intro: I'm the author and maintainer of the f71882fg driver. On 05/28/2010 11:25 PM, Maarten Maathuis wrote:
This appears to be a pretty new Super I/O IC, which i found on my new motherboard (MSI 870A-G54). I couldn't find a datasheet, but this link (http://code.google.com/p/open-hardware-monitor/source/detail?r=130#) suggests that it can be trivially added to the f71882fg driver. So i tried that, pretending it was a f71889fg. This is the output i got, i appended what i think about the values: f71889ed-isa-0600 Adapter: ISA adapter in0: +1.66 V in1: +0.90 V (max = +2.04 V)<-- Vcore, 1.11 V when in high power mode, this seems accurate (compared to bios) in2: +1.07 V in3: +0.88 V in4: +0.62 V in5: +1.27 V in6: +1.55 V in7: +1.66 V in8: +1.64 V fan1: 785 RPM<-- cpu fan, accurate (compared to bios) fan2: 0 RPM ALARM fan3: 0 RPM ALARM temp1: +24.0 C (high = +255.0 C, hyst = +251.0 C) ALARM<-- cpu temp, probably accurate (compared to bios) (crit = +255.0 C, hyst = +251.0 C) ALARM sensor = Intel PECI temp2: FAULT (high = +255.0 C, hyst = +251.0 C) (crit = +255.0 C, hyst = +251.0 C) sensor = transistor temp3: +33.0 C (high = +255.0 C, hyst = +253.0 C) ALARM<-- system temp, probably accurate (compared to bios) (crit = +255.0 C, hyst = +253.0 C) ALARM sensor = transistor So please tell me what you think, any ideas how this can be improved. Especially the system voltages are horribly mis-calibrated it seems.
Well first fo all we will need a datasheet, yes really. The fintek chips are quite complex when it comes to there fan control parts and there then to be subtile differences between all the different versions, see all the special handling for various revisions already present in the driver. Luckily Fintek usually provides datasheet to the public. But they tend to lag a bit between devices showing up in the market and actually publishing a datasheet. They don't want to put the sheet up till it is "final" (or so I think), where as products are already being sold in the market with the chip in them (presumably made with the use of non final datasheets). So the thing to do is to keep an eye on: http://www.fintek.com.tw/eng/products.asp?BID=1&SID=17 And when a datasheet shows up there drop me a mail and I'll extend the driver and then ask you to test it.
