Systems and methods for composing or decomposing a composite image for firmware update images

摘要

In at least some embodiments, a computer system comprises a processor, a memory coupled to the processor. The computer system also comprises a network interface coupled to the processor. The memory stores a firmware composition tool that, when executed by the processor, is to build a composite image comprising an arbitrary number of firmware update images according to a set of format rules that enables a self-describing aggregation of the arbitrary number of firmware update images.

1. A computer system comprising:
a processor; a memory coupled to said processor; and a network interface coupled to the processor, wherein the memory stores a firmware composition tool that, when executed by the processor, is to build a composite image comprising an arbitrary number of firmware update images according to a set of format rules that enables a self-describing aggregation of the arbitrary number of firmware update images, all of the firmware update images within the composite image being at a same nesting level, and a single table of contents comprising entries describing the firmware update images, all entries in the table of contents being at the same nesting level, wherein a first entry in the table of contents describes the entire composite image as a type of payload; and wherein the composite image outlines an order the arbitrary number of firmware update images should be implemented based on dependencies.
