US 2020/0287955 A1 · VIDEO REDIRECTION ACROSS MULTIPLE INFORMATION HANDLING SYSTEMS (IHSs) USING A GRAPHICS CORE AND A BUS BRIDGE INTEGRATED INTO AN ENCLOSURE CONTROLLER (EC)

Abstract

Embodiments of systems and methods for providing video redirection across multiple Information Handling Systems (IHSs) are discussed. In some embodiments, a method may include: receiving, via a video redirection client, a video stream produced by a video redirection server executed by a Baseboard Management Controller (BMC) of a selected IHS; providing the video stream to a framebuffer driver, where the frame buffer driver is configured to: (i) store frame data from the video stream onto a framebuffer memory; and (ii) in response to a determination that a host is not available, transmit control signals to a graphics core via an Advanced Microcontroller Bus Architecture (AMBA) high-performance bus (AHB)-to-Peripheral Component Interconnect (PCI) (AHB-to-PCI) bridge, where the graphics core is accessible via a PCI bus exclusively when the host is available; and transmitting the frame data to a display coupled to the chassis.

Dependent claims

An Enclosure Controller (EC) coupled to a plurality of Information Handling Systems (IHSs) in a chassis, the EC comprising:

a processor core;
a graphics core coupled to the processor core via an Advanced Microcontroller Bus Architecture (AMBA) high-performance bus (AHB)-to-Peripheral Component Interconnect (PCI) (AHB-to-PCI) bridge, wherein the graphics core is accessible to the processor core via a PCI bus through a host;
and
a memory coupled to the processor core, the memory having program instructions stored thereon that, upon execution, cause the EC to:
receive, via a video redirection client, a video stream produced by a video redirection server executed by a Baseboard Management Controller (BMC) of a given one of the plurality of IHSs;
provide the video stream to a driver, wherein the buffer driver is configured to:
(i) store data from the video stream onto a memory;
and (ii) in response to a determination that the host is not available, transmit control signals to the graphics core via the AHB-to-PCI bridge;
and
transmit the data to a display coupled to the chassis.
