Abstract:
(EN)
Various aspects include methods for implementing a firmware patch infrastructure. Various aspects may include identifying a patchable object from a firmware source code image based on a symbol in the patchable object's name, generating a patchable firmware source code file by injecting a first call to the patchable object configured to call to an indirection table and a second call to the patchable object configure to execute the patchable object, building a patchable firmware source code image from a plurality of patchable firmware source code files including the patchable firmware source code file having the first call to the patchable object and the second call to the patchable object, and creating the indirection table including an entry for the first call from the patchable firmware source code image having an indication to implement the second call in the patchable firmware source code image.
