Critical Temperature Detection

Critical Temperature detection is performed by monitoring the package temperature. This feature is intended for graceful shutdown before the THERMTRIP# is activated. However, the processor execution is not guaranteed between critical temperature and THERMTRIP#. If the Adaptive Thermal Monitor is triggered and the temperature remains high, a critical temperature status and sticky bit are latched in the PACKAGE_​THERM_​STATUS (1B1h) MSR and the condition also generates a thermal interrupt, if enabled. For more details on the interrupt mechanism, refer to Intel® 64 Architectures Software Developer’s Manual (671200) .
