8.5.1
Core Programmable Thresholds
Two programmable thresholds per CPU core sensor are provided for Advanced
Configuration and Power Interface (ACPI) compliant thermal management via software.
The thresholds are specified as an offset below T
J-MAX
via registers and configured to
trigger a CPU thermal interrupt. ACPI software routines then take appropriate action
when the interrupts get serviced.
8.5.2
Core HOT Threshold
The Core HOT threshold indicates that a thermal sensor in the core has exceeded the
maximum-allowed operating temperature (defaults to T
J-MAX
). The die temperature
readout of each sensor is periodically compared against the T
J-MAX
value. Corrective
actions are taken if the threshold value is exceeded. The Core HOT condition triggers
the Intel
®
Thermal Monitor 1 or Intel
®
Thermal Monitor 2 thermal control circuit
mechanisms (if enabled).
Programmable hysteresis offsets are utilized to prevent oscillation of the Core HOT
condition around the threshold. Hysteresis in terms of temperature offset is specified
for both triggering and deactivating the Core HOT condition.
8.5.3
Core Out of Specification Threshold
The Core Out of Specification threshold indicates that a thermal sensor is close to
reaching a catastrophic temperature which permanently damages the device. This
programmable threshold is set above T
J-MAX
with a default value of 5 °C above T
J-MAX
.
This threshold does not trigger any thermal throttling mechanisms.
