22*bbf21555SRichard Lowe.Sh DESCRIPTION
23*bbf21555SRichard LoweThe
24*bbf21555SRichard Lowe.Nm
25*bbf21555SRichard Lowedriver provides the system with a means of reading the per-core and,
26*bbf21555SRichard Lowewhen available, per-package digital temperature sensors on Intel CPUs.
27*bbf21555SRichard LoweCurrently, the
28*bbf21555SRichard Lowe.Nm
29*bbf21555SRichard Lowedriver supports Intel Core family processors after Penryn
30*bbf21555SRichard Lowemicroarchitecture and Intel Atom processors starting with the Silvermont
31*bbf21555SRichard Lowemicroarchitecture.
32*bbf21555SRichard Lowe.Pp
33*bbf21555SRichard LoweTemperature information is available to the system via the fault
34*bbf21555SRichard Lowemanagement architecture
35*bbf21555SRichard Lowe.Pq FMA .
36*bbf21555SRichard LoweThe file system location and programming interface to the
37*bbf21555SRichard Lowe.Nm
38*bbf21555SRichard Lowedriver are considered
39*bbf21555SRichard Lowe.Sy Volatile ,
40*bbf21555SRichard Lowesubject to change without notice, and should not be used directly.
41*bbf21555SRichard LoweRaw temperature information can be dumped through the FMA developer
