Abstract

Example embodiments disclosed herein relate to distributing information. A set of information about components of a computing device is retrieved from a low-level system of the computing device. Programs are determined to be sent data based on the set of information.

Claims

1. A computing device comprising:

a controller to determine a set of power usage data for a plurality of low-level components of the computing device;

an event capture module to determine an event;

a fetching module to fetch the set based on the event; and

a subscription module to determine subscription information about a plurality of programs indicating whether the respective programs should be sent the set, wherein the subscription information is based on the event, and wherein the controller expires the set if the set is fetched.

2. The computing device of claim 1, wherein the controller is part of a low-level system that includes a power monitor circuit, and wherein the controller interfaces with the power monitor circuit to determine the power usage data.

3. The computing device of claim 1,

wherein the controller determines another set of power usage data after the set expires,

wherein the event capture module determines another event associated with the other set, and

wherein the subscription module determines a plurality of other programs to send the other set based on the other event.

4. The computing device of claim 1,

wherein the subscription information includes respective identifiers of the programs and associated information types for which the respective programs are interested, and

wherein the set is determined to be sent to the respective programs that are interested in an information type associated with the set.

5. A method comprising:

retrieving a set of information about a plurality of low-level components of a computing device from a low-level system component,

wherein the set is expired after retrieval; and

determining a plurality of programs to send data based on the set of information.

6. The method of claim 5, further comprising:

receiving a request from one of the programs to subscribe to the information; and

updating subscription information to indicate that the one program is subscribed to receive the information,

wherein the determination of the programs is based on the subscription information.

7. The method of claim 6, wherein the subscription information includes event information and wherein the event information indicates an event that if triggered indicates that the set should be sent to the one program, the method further comprising:

determining that the event has been triggered, wherein the determination of the programs is further based on the triggered event.

8. The method of claim 5, wherein the information includes power usage data.

15. The non-transitory computer-readable storage medium of claim 8, wherein the components include at least one of a networking module, a storage module, a presentation module, and a processor.

9. A non-transitory computer-readable storage medium storing instructions that, if executed by a processor, cause the processor to:

retrieve a set of power usage data about a plurality of components of a computing device from a low-level system of the computing device;

determine subscription information for a plurality of services for the power usage data; and

publish the set to the services based on the subscription information.

10. The non-transitory computer-readable storage medium of claim 9, further comprising instructions that, if executed by the processor, cause the processor to:

receive a subscription request for the power usage data from one of the services; and

update the subscription information to indicate that the one service is subscribed to receive the power usage data.

11. The non-transitory computer-readable storage medium of claim 9,

wherein the low-level system expires the set when the set is retrieved.

12. The non-transitory computer-readable storage medium of claim 11, further comprising instructions that, if executed by the processor, cause the processor to:

retrieve another set of the power usage data from the low-level system; and

publish the other set to the services based on the subscription information.

13. The non-transitory computer-readable storage medium of claim 12, wherein the low-level system collects the other set after the set is expired.

14. The non-transitory computer-readable storage medium of claim 11, wherein the low-level system includes at least one of a basic input output system (BIOS) and a keyboard controller.
