Systems, apparatuses and methods may provide for technology that initializes a host-managed device memory (HDM) as a temporary proxy for a system memory, wherein the HDM is associated with an accelerator. The technology also creates a shadow copy of boot firmware code in the HDM and executes one or more boot instructions in the shadow copy of the boot firmware code. In one example, the one or more boot instructions are to be one or more of executed before an initialization of the system memory or executed in parallel with the initialization of the system memory.

Accelerating system boot times via host-managed device memory

In accordance with embodiments disclosed herein, there is provided systems and methods for extending a root complex to encompass an external component. A processor includes a processor core and root complex circuitry coupled to the processor core. The processor core is to execute a basic input/output system (BIOS) and an operating system (OS). The root complex circuitry includes a coherent interface port and a downstream port. The root complex circuitry is to couple to an external component via the downstream port and the coherent interface port. The BIOS, to extend a root complex beyond the root complex circuitry to encompass the external component, is to obfuscate the downstream port from the OS, define a virtual root bridge for the external component, and enable a security check at the external component to provide protection for the coherent interface port and the downstream port.
