1. An information handling system comprising:
a plurality of graphic processing units (GPUs); and
a basic input/output system (BIOS) to communicate with the GPUs, the BIOS to:
initiate boot operations for the information handling system; and
during a pre-extensible firmware interface phase of the boot operations, the BIOS to initialize a video memory associated with the GPUs; and
an advanced graphics synchronization node (AGN) to communicate with the BIOS, the AGN to:
during the boot operations:
generate a firmware override table based on data in the video memory; and
generate a redirection override table based on the data in the video memory; and
during operating system runtime operations:
utilize the firmware override table to synchronize outputs from the GPUs; and
utilize the redirection override table to enable a firmware update for one of the GPUs without a reboot of the information handling system.
