Abstract: In an information handling system that includes one or more PCIe devices, responsive to enumerating a PCIe device and adding the PCIe device to a configuration space of the platform, a mapping entry is added to a device handler mapping table to associate a device handler for the PCIe device with information for accessing the PCIe device. If the PCIe device fails to enumerate in a boot path, a virtual pseudo PCIe (VPP) node corresponding to the PCIe device may be created and enumerated to enable the boot to complete. Upon subsequently detecting and enumerating the actual, physical PCIe device, the VPP node and the PCIe device may be connected to enable the full functionality of the PCIe device without re-booting the platform.

Abstract: Disclosed subject matter enables early PEI phase initialization of GPU cores and dynamic configuration of the GPU core computing to accept sliced workloads for parallel execution. Disclosed methods dynamically adapt based on various factors to a graphics rendering context determined based on factors such as the connected monitors, their various resolutions, etc., to provide advanced GPU rendering in pre-boot operating environment. Methods and systems may support pre-boot hybrid graphics rendering including dynamic utilization of integrated and discrete GPU cards/memory, along with the central processing unit (CPU) and cache to provide seamless and faster graphics rendering operations for all preboot requirements.
