Power limit alterations of component types

A system comprising:

• a main circuit assembly that includes a central processing unit (CPU) of a computing system;
• a sub-circuit assembly that includes a sub processing unit of the computing system;
• a voltage power manager (VPM) device to:
• assert a first processor hot (PROCHOT) function of the sub-circuit assembly to alter a power state of the sub-circuit assembly from a first state to a second state in response to an event of the system;
• determine if the event of the system continues when the sub-circuit assembly is performing at the second state;
• assert a second PROCHOT function of the sub-circuit assembly to alter the power state of the sub-circuit assembly from the second state to a third state in response to the event of the system continuing when the sub-circuit assembly is performing at the second state;
• and
• de-assert the first PROCHOT and second PROCHOT function in response to a determination that the event of the system has ended.

A method comprising:

• determining a power limit for a first state of a graphics processing unit (GPU) of a computing system that includes the GPU and a central processing unit (CPU);
• determining when an event occurs on the computing system that is affected by a first power state of the GPU;
• altering the first power state of the GPU to a second power state that is lower than the first power state in response to determining that the event has occurred;
• and
• altering the second power state of the GPU to a third power state that is lower than the second power state in response to determining that the event is occurring when the GPU is in the second power state.
