Description
-----------
This driver permits reading temperature sensor(s) embedded inside AMD K8 CPUs.
Official documentation says that it works from revision F of K8 core, but
in fact it seems to be implemented for all revisions of K8 except the first
two revisions (SH-B0 and SH-B3).
This driver permits reading temperature sensor(s) embedded inside AMD K8
family CPUs (Athlon64/FX, Opteron). Official documentation says that it works
from revision F of K8 core, but in fact it seems to be implemented for all
revisions of K8 except the first two revisions (SH-B0 and SH-B3).
Please note that you will need at least lm-sensors 2.10.1 for proper userspace
support.
There can be up to four temperature sensors inside single CPU. The driver
will auto-detect the sensors and will display only temperatures from
