Abstract

An apparatus is provided, where the apparatus includes a plurality of components, wherein an individual component has a corresponding throttling priority of a plurality of throttling priorities. The apparatus further includes logic to selectively throttle one or more of the plurality of components. In an example, an order in which the one or more of the plurality of components are to be throttled may be based on the plurality of throttling priorities.

First claim

We claim:

1. A non-transitory computer-readable storage medium to store instructions that, when executed by a processor, cause the processor to:
receive a plurality of throttling priorities for a corresponding plurality of hardware components;
determine a sequence in which hardware components of the corresponding plurality of hardware components are to be throttled, based on the plurality of throttling priorities; and
respectively assign the plurality of throttling priorities to the corresponding plurality of hardware components, based on input received from software executed on the processor, the software receiving the input including both of an operating system (OS) and a user interface,
wherein the corresponding plurality of hardware components include a graphics processing unit (GPU) and a central processing unit (CPU), the GPU to be associated with a first throttling priority of the plurality of throttling priorities and the CPU to be associated with a second throttling priority of the plurality of throttling priorities, and
wherein the GPU is throttled prior to the CPU in response to the second throttling priority being different from the first throttling priority.

2. The non-transitory computer-readable storage medium of claim 1 , wherein either the GPU or the CPU is throttled first, or both the GPU and the CPU are throttled in response to the first throttling priority being the same as the second throttling priority.

3. The non-transitory computer-readable storage medium of claim 1 , wherein the sequence in which the hardware components are to be throttled is based on a corresponding descending sequence of throttling priorities of the plurality of throttling priorities.

4. The non-transitory computer-readable storage medium of claim 1 , wherein a hardware component of the corresponding plurality of hardware components is to be throttled by a reduction of a frequency or voltage of the hardware component.

5. The non-transitory computer-readable storage medium of claim 1 , wherein when the input is received by a power management unit of the processor.

6. The non-transitory computer-readable storage medium of claim 5 , wherein the power management unit is to respectively assign the plurality of throttling priorities to the corresponding plurality of hardware components based on the input.

7. A non-transitory computer-readable storage medium to store instructions that, when executed by a processor, cause the processor to:
receive a plurality of throttling priorities for a corresponding plurality of hardware components; and
determine a sequence in which hardware components of the corresponding plurality of hardware components are to be throttled, based on the plurality of throttling priorities; and
respectively assign the plurality of throttling priorities to the corresponding plurality of hardware components, based on input received from software executed on the processor, the software receiving the input including both of an Operating System (OS) and a User Interface, wherein when the input is received from the OS:
the OS is to store the input to a memory; and
the processor is to receive the input from the memory and to respectively assign the plurality of throttling priorities to the corresponding plurality of hardware components based on the input received from the OS via the memory.

8. The non-transitory computer-readable storage medium of claim 7 , wherein the corresponding plurality of hardware components include a first hardware component and a second hardware component, the first hardware component to be associated with a first throttling priority of the plurality of throttling priorities and the second hardware component to be associated with a second throttling priority of the plurality of throttling priorities.

9. The non-transitory computer-readable storage medium of claim 8 , wherein the first hardware component comprises a graphics processing unit (GPU) and the second hardware component comprises a central processing unit (CPU).

10. The non-transitory computer-readable storage medium of claim 9 , wherein the GPU is throttled prior to the CPU in response to the second throttling priority being different from the first throttling priority.

11. The non-transitory computer-readable storage medium of claim 9 wherein either the GPU or the CPU is throttled first in response to the first throttling priority being the same as the second throttling priority.

12. The non-transitory computer-readable storage medium of claim 7 , wherein the sequence in which the hardware components are to be throttled is based on a corresponding descending sequence of throttling priorities of the plurality of throttling priorities.

13. The non-transitory computer-readable storage medium of claim 7 , wherein a component of the corresponding plurality of hardware components is to be throttled by a reduction of a frequency or voltage of the hardware component.

14. The non-transitory computer-readable storage medium of claim 7 , wherein when the input is received by a power management unit of the processor.

15. The non-transitory computer-readable storage medium of claim 14 , wherein the power management unit is to respectively assign the plurality of throttling priorities to the corresponding plurality of hardware components based on the input.

16. A system comprising:
one or more storage devices to store firmware or software comprising instructions;
one or more processors to execute the instructions to perform a plurality of operations including:
receiving a plurality of throttling priorities for a corresponding plurality of hardware components;
determining a sequence in which hardware components of the corresponding plurality of hardware components are to be throttled, based on the plurality of throttling priorities; and
respectively assigning the plurality of throttling priorities to the corresponding plurality of hardware components, based on input received from software executed on the processor, the software receiving the input including both of an operating system (OS) and a user interface,
wherein the corresponding plurality of hardware components include a graphics processing unit (GPU) and a central processing unit (CPU), the GPU to be associated with a first throttling priority of the plurality of throttling priorities and the CPU to be associated with a second throttling priority of the plurality of throttling priorities, and
wherein the GPU is throttled prior to the CPU in response to the second throttling priority being different from the first throttling priority.

17. The system of claim 16 , wherein either the GPU or the CPU is throttled first, or both the GPU and the CPU are throttled in response to the first throttling priority being the same as the second throttling priority.

18. The system of claim 16 , wherein the sequence in which the hardware components are to be throttled is based on a corresponding descending sequence of throttling priorities of the plurality of throttling priorities.

19. The system of claim 16 , wherein a hardware component of the corresponding plurality of hardware components is to be throttled by a reduction of a frequency or voltage of the hardware component.

20. The system of claim 16 , wherein when the input is received by a power management unit of the processor.
