@ -132,20 +132,3 @@ On Family 17h and Family 18h CPUs, additional temperature sensors may report
Core Complex Die (CCD) temperatures. Up to 8 such temperatures are reported
as temp{3..10}_input, labeled Tccd{1..8}. Actual support depends on the CPU
variant.
Various Family 17h and 18h CPUs report voltage and current telemetry
information. The following attributes may be reported.
Attribute Label Description
=============== ======= ================
in0_input Vcore Core voltage
in1_input Vsoc SoC voltage
curr1_input Icore Core current
curr2_input Isoc SoC current
=============== ======= ================
Current values are raw (unscaled) as reported by the CPU. Core current is
reported as multiples of 1A / LSB. SoC is reported as multiples of 0.25A
/ LSB. The real current is board specific. Reported currents should be seen
as rough guidance, and should be scaled using sensors3.conf as appropriate
for a given board.
