Management of Power States of Devices and Systems

A computing system comprising:

• a first processor;
• a second processor that is different from the first processor;
• and
• a processor unit operatively couples to the first processor and the second processor;
• wherein the first processor is configured to:
• cause the second processor to be in a low power level;
• and
• while the second processor is in the low power level, cause offload of one or more operations associated with the second processor to the processor unit.

A method comprising:

• determining, by one or more processors of a computing system, whether a power element of the computing system corresponding to an execution state of the computing system is at an inactive power level;
• responsive to determining that the power element is at the inactive power level, causing, by the one or more processors, a system activity governor (SAG) of the computing system to communicate a suspend request to one or more components of the computing system;
• determining, by the one or more processors, whether the suspend request is successful;
• and
• responsive to determining that the suspend request is unsuccessful:
• causing, by the one or more processors, the SAG to notify one or more listeners of the suspend request being unsuccessful;
• determining, by the one or more processors, whether the power element is still at the inactive power level;
• and
• responsive to determining that the power element is still at the inactive power level, causing, by the one or more processors, the SAG to log an error corresponding to the suspend request being successful.

A non-transitory computer readable storage medium storing one or more instructions configured for execution by a computing system having one or more processors, the one or more instructions for performing a method comprising:

• determining whether a power element of the computing system corresponding to an execution state of the computing system is at an inactive power level;
• responsive to determining that the power element is at the inactive power level, causing a system activity governor (SAG) of the computing system to communicate a suspend request to one or more components of the computing system;
• determining whether the suspend request is successful;
• and
• responsive to determining that the suspend request is unsuccessful:
• causing the SAG to notify one or more listeners of the suspend request being unsuccessful;
• determining whether the power element is still at the inactive power level;
• and
• responsive to determining that the power element is still at the inactive power level, causing the SAG to log an error corresponding to the suspend request being successful.
