Salut Jean, Yes, i think you must be right there, i can't come up with any other explanation of why your board BIOS would scale up the temperature. The LM75 is an air-flow temperature sensor, not a die temperature sensor. My point was: you're right to modify your sensors.conf to scale it up by 2.0, but it probably shouldn't be the default setting. As far as i know (which is not that much as i'm a software guy), the National LM75 is very commonly used, though i could ask one of our hardware gurus if you're interested. One of our boards has an LM75, an LM87 and a NE1617 very close together. All three have internal temp sensors, and all three report pretty much the exact same temperature (typically around 25 to 30C in our strongly air-conditionned lab). The LM87 has pins for external sensor diodes which are connected to FPGA diodes. Those are die temperatures, and are always a lot higher (depending of whether the FPGA has a heat-sink or not), around 40 to 50C (hyst is typically 75C, limit 85C). I was hoping to contribute some drivers to your project, based on your interest and if i get some time (Philips ne1617, Vitesse VSC055, or more fun, XFP laser 10G transceivers...). -denis --- Jean Delvare <khali at linux-fr.org> wrote: > I did that and could see the chips.
