319 Inaccurate Temperature Measurement
Description
The internal thermal sensor used for CurTmp (F3xA4[31:21]), hardware thermal control (HTC),
software thermal control (STC), and the sideband temperature sensor interface (SB-TSI) may report
inconsistent values.
software thermal control (STC), and the sideband temperature sensor interface (SB-TSI) may report
inconsistent values.
Potential Effect on System
HTC, STC and SB-TSI do not provide reliable thermal protection. This does not affect THERMTRIP.
Suggested Workaround
None. Systems should be designed with conventional thermal control and throttling methods or
utilize PROCHOT_L functionality based on temperature measurements from an analog thermal diode
(THERMDA/THERMDC).
utilize PROCHOT_L functionality based on temperature measurements from an analog thermal diode
(THERMDA/THERMDC).
Systems should not rely on the HTC features, STC features or use SB-TSI.
Software should not modify HtcTmpLmt (F3x64[22:16]) or enable any of the STC features by setting
StcPstateEn, StcApcTmpLoEn, StcApcTmpHiEn, StcSbcTmpLoEn, or StcSpcTmpHiEn
(F3x68[5,3:0]).
StcPstateEn, StcApcTmpLoEn, StcApcTmpHiEn, StcSbcTmpLoEn, or StcSpcTmpHiEn
(F3x68[5,3:0]).
Fix Planned
Yes
