Method and apparatus for external processor thermal control
A system and method for throttling a slave component of a computer system to reduce an overall temperature of the computing system upon receiving a first signal is disclosed. The first signal may be from a master component indicating that a temperature for the master component has exceeded its threshold temperature. The slave component may send a second signal to indicate that a temperature for the slave component has exceeded its temperature. The master component would then initiate throttling of the master component to reduce the overall temperature of the computing system. The master component may be throttled to a degree less than the slave component. A first component may be designated the master component and the second component may be designated the slave component based on a selection policy.
1. A method, comprising:
receiving a first temperature from a first integrated circuit device, the first temperature indicating the first integrated circuit device exceeds a first threshold temperature;
applying a cooling policy for a second integrated circuit device, at a first time, in response to receiving the first temperature, wherein the second integrated circuit device has a direct thermal influence on the first integrated circuit device, and wherein a cooling policy for the first integrated circuit device is not applied at the first time;
receiving a second temperature from the first integrated circuit device; and
applying the cooling policy for the first integrated circuit device, at a time subsequent to the first time, in response to receiving the second temperature, the second temperature indicating the first integrated circuit device continues to exceed the first threshold temperature.
2. The method of claim 1 , wherein applying the cooling policy further comprises applying passive cooling.
3. The method of claim 2 , wherein the passive cooling comprises device throttling.
4. The method of claim 1 , further comprising:
the first integrated circuit device sending the second integrated circuit device a first signal in response to the first integrated circuit device exceeding the first threshold temperature.
5. The method of claim 4 , further comprising:

receiving a second temperature from the first integrated circuit device; and
applying the cooling policy for the first integrated circuit device, at a time subsequent to the first time, in response to receiving the second temperature, the second temperature indicating the first integrated circuit device continues to exceed the first threshold temperature.
7. The non-transitory computer-readable recording medium of claim 6 , wherein applying the cooling policy further comprises applying passive cooling.
8. The non-transitory computer-readable recording medium of claim 7 , wherein the passive cooling comprises device throttling.
9. The non-transitory computer-readable recording medium of claim 6 , wherein the performed method further comprising:
the first integrated circuit device sending the second integrated circuit device a first signal in response to the first integrated circuit device exceeding the first threshold temperature.
10. The non-transitory computer-readable recording medium of claim 9 , wherein the performed method further comprising:
