Abstract

An information handling system identifies modified modules based on a comparison of first binaries of a first version of a system firmware with second binaries of a second version of the system firmware. The system bundles the modified modules including offset definitions as a binary file.

First claim

What is claimed is:

1 . A method comprising:
comparing, by a processor, first binaries of a first version of a system firmware with second binaries of a second version of the system firmware; identifying modified modules based on the comparing of the first binaries of the first version of the system firmware and the second binaries of the second version of the system firmware; and bundling the modified modules including offset definitions as a binary file.

2 . The method of claim 1 , wherein the offset definitions are in a segment offset table.

3 . The method of claim 1 , wherein the bundling of the modified modules include a signature and a hash value based on the modified modules.

4 . The method of claim 1 , further comprising collecting other firmware update to include in the bundling of the modified modules.

5 . The method of claim 1 , further comprising calculating a hash value based on a set of drivers.

6 . The method of claim 1 , further comprising collecting information associated with drivers that are split into at least two modules.

7 . The method of claim 1 , further comprising generating a payload offset table with a dynamic link of an overflow offset.

8 . The method of claim 1 , further comprising interpolating the offset definitions of the modified modules with platform offset definitions which results in generating a new flash offset map.

9 . An information handling system, comprising:
a processor; and a memory storing instructions that when executed cause the processor to perform operations including:
comparing first binaries of a first version of a system firmware with second binaries of a second version of the system firmware;
identifying modified modules based on the comparing of the first binaries of the first version of the system firmware and the second binaries of the second version of the system firmware; and
bundling the modified modules including offset definitions as a binary file.

10 . The information handling system of claim 9 , wherein the offset definitions are in a segment offset table.

11 . The information handling system of claim 9 , wherein the bundling of the modified modules include a signature and a hash value based on the modified modules.

12 . The information handling system of claim 9 , wherein the operations further comprise calculating a hash value based on a set of drivers.

13 . The information handling system of claim 9 , wherein the operations further comprise collecting information associated with drivers that are split into at least two modules.

14 . The information handling system of claim 9 , wherein the operations further comprise generating a payload offset table with a dynamic link of an overflow offset.

15 . The information handling system of claim 9 , wherein the operations further comprise interpolating the offset definitions of the modified modules with platform offset definitions which results in generating a new flash offset map.

16 . A non-transitory computer-readable medium to store instructions that are executable to perform operations comprising:
comparing first binaries of a first version of a system firmware with second binaries of a second version of the system firmware; identifying modified modules based on the comparing of the first binaries of the first version of the system firmware and the second binaries of the second version of the system firmware; and bundling the modified modules including offset definitions as a binary file.

17 . The non-transitory computer-readable medium of claim 16 , wherein the offset definitions are in a segment offset table.

18 . The non-transitory computer-readable medium of claim 16 , wherein the bundling of the modified modules include a signature and a hash value based on the modified modules.

19 . The non-transitory computer-readable medium of claim 16 , wherein the operations further comprise generating a payload offset table with a dynamic link of an overflow offset.

20 . The non-transitory computer-readable medium of claim 16 , wherein the operations further comprise interpolating the offset definitions of the modified modules with platform offset definitions which results in generating a new flash offset map.
