Conrad Meyer <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- Version|11.2-STABLE |CURRENT --- Comment #12 from Conrad Meyer <[email protected]> --- (In reply to gosha-necr from comment #11) It seems like probably the HDD temperature can be inferred to be a floor. The CPU is unlikely to be cooler. As far as diagnosing, I am kind of stuck. Maybe these CPUs run with Tctl at some offset. But I don't know what the offset is. One more PCI read for you: pciconf -r pci0:0:24:3 0x64 This is "Hardware Thermal Control" and bits [22:16] tell us the "HtcTmpLimit." As the BKDG notes, the CurTmp value does not reflect an actual temperature, but rather: > Tctl is a temperature on its own scale aligned to the processors cooling > requirements. Therefore Tctl does not represent a temperature which could be > measured on the die or the case of the processor. Instead, it specifies the > processor temperature relative to the maximum operating temperature, Tctl,max. > Tctl,max is specified in the power and thermal data sheet. So maybe there is some relationship between Tctl,max and HtcTmpLimit. Or maybe we can find a power and thermal data sheet for 15h and find the correct offsets for A8-7600 / FX-8300. I bumped bug version to "CURRENT" because I don't believe there are any significant differences between amdtemp on 15h in 11.2 and on CURRENT. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "[email protected]"
