Application: Impactless firmware update (Patent ID: US20230401054A1)
The patent filed by Advanced Micro Devices Inc. describes techniques for updating firmware without requiring a system reset. This involves preserving state information related to firmware services, suspending processing of firmware service requests, loading an updated firmware image, and then resuming processing based on the preserved state information and the new firmware image. The patent also covers recreating unpreserved states of other firmware services upon resumption of processing.
The patent includes claims for a bootable platform with subsystems that can perform firmware services based on an initial firmware image and update the firmware without disrupting the operation of the system. The claims detail steps such as preserving state information, suspending processing of service requests, loading the updated firmware image, and resuming processing based on the new image and preserved state information. Additional claims cover discarding and recreating state information, bypassing hardware configuration services, retaining portions of the initial firmware image, authenticating the updated firmware image, queuing service requests during updates, handling errors, and utilizing multiple processors for the update process. These claims outline a comprehensive method for updating firmware seamlessly within a bootable platform.
