Looking at amdtemp_gettemp() there, I suspect the 0x15 family uses yet another number or placement of register bits; your ~13C to 15C range of temps shown seems much more likely to be in the ~52C to 60C range .. cc'ing jkim@, although others have messed with amdtemp more recently. > > > acpi0: <7596MS A7596100> on motherboard > > > # sysctl dev.amdtemp > > > dev.amdtemp.0.%desc: AMD CPU On-Die Thermal Sensors > > > dev.amdtemp.0.%driver: amdtemp > > > dev.amdtemp.0.%parent: hostb4 > > > dev.amdtemp.0.sensor_offset: 0 > > > dev.amdtemp.0.core0.sensor0: 15.3C > > > > > > # sysctl -a dev.cpu | grep temp > > > dev.cpu.0.temperature: 15.2C [..] > > > dev.cpu.7.temperature: 15.2C > > > > > > I am not sure how this ^ relates to what acpi reports under thermal. I assume dev.amdtemp.0.core0.sensor0 is the source for all of those. > I am not sure how correct these numbers are but I've enabled AMD's > Cool'n'Quiet thingi in BIOS. Looks like you need to ask someone to add support for family 0x15. As for Eric, with no _TZ support, I don't know how you'd handle overtemps. > > And neither of these are reporting hw.acpi.thermal .. is it because the > > BIOS / ACPI doesn't present thermal zone information? > I'd believe so. > > > Or there aren't > > suitable drivers to interpret it?

It's no use to me and the list swallowed it; you'd need to put it up at an URL somewhere .. but as it has no Thermal Zone section it can't help with this issue anyway. > By the time I collected everything, > > # sysctl dev.cpu | grep temp > dev.cpu.0.temperature: 14.0C > dev.cpu.1.temperature: 14.0C > dev.cpu.2.temperature: 14.0C > dev.cpu.3.temperature: 14.0C > dev.cpu.4.temperature: 14.0C > dev.cpu.5.temperature: 14.0C > dev.cpu.6.temperature: 14.0C > dev.cpu.7.temperature: 14.0C 56C most likely, unless there's also an offset. I'm out of clues .. cheers, Ian
