pchtempdriver provides the system the ability to read the digital temperature sensor found on several Intel platform controller hub (PCH) chipsets. The following chipsets are supported which cover most Intel Core family (non-Atom) CPUs starting with the Haswell generation:
Temperature information is available to the system via the fault
management architecture (FMA). The file system location and programming
interface to the
pchtemp driver are considered
Volatile, subject to change without notice, and should not
be used directly. Raw temperature information can be dumped through the FMA
developer utility fmtopo.
