Sorry .. I didn't look closely enough at all. The version on head does appear to support the 0x15 family as well, and quite a bit of the code has been reworked and augmented. #define DEVICEID_AMD_MISC15 0x1603 > 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 .. That's changed too .. but none of this explains why yours is reporting (apparently) one quarter of the real temperature. Out of my depth .. cheers, Ian _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-acpi To unsubscribe, send any mail to "[email protected]"
