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.
