Power conservation and standby graphics rendering in an information handling system

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.
