System, module, and method of enabling a video interface within a limited resource enabled information handling system
First Claim
1. An information handling system comprising:
- a host processing system, includinga first display;
a host processor configured to output a first video signal; and
a video multiplexer configured to receive the first video signal and to selectably output the first video signal to the display; and
a remote processing module integrated within a housing configured to house the host processor and the video multiplexer, wherein the remote processing module is configured to be inserted into the information handling system, and coupled to the host processing system, the remote processing module including;
a remote processor configured to output a second video signal;
an interface between the host processing system and the remote processing module, the interface including a video output channel configured to provide the second video signal to the video multiplexer, wherein the video multiplexer is further configured to receive the second video signal and to selectably output the second video signal to the display during a reduced operating state of the host processing system and wherein the interface comprises a Peripheral Component Interface—
Express (PCIe) interface.

Abstract
An information handling system includes a host processing system and a remote processing system. The host processing system includes a display, a host processor, and a video multiplexer that receives a video signal from the host processor and outputs the video signal to the display. The remote processing module is coupled to the host processing system and includes a remote processor configured to output a second video signal, and an interface between the host processing system and the remote processing system. The interface includes a video output channel configured to provide the second video signal to the video multiplexer. The video multiplexer is further configured to receive the second video signal and to output the second video signal to the display during a reduced operating state of the host processing system.

9. A method comprising:
-
detecting an operating condition of a host processing system of an information handling system, wherein the host processing system includes a fully operating state, and a powered down operating state; detecting a video output event of a remote processing module within the information handling system when the host processing system is in the powered down operating, state; and outputting a video output signal from the remote processing module to a video multiplexer integrated within a housing configured to house the remote processing module and a host processor, the video multiplexer being configured to output video using a display of the host processing system, wherein the video output signal is provided via a Peripheral Component Interface—
Express (PCIe) interface. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
