A game cloud server, a method of operating a cloud server, and a method of playing a game on a game cloud server are disclosed. In one example, the game cloud server includes: (1) one or more processing units that virtually supports different gaming applications according to a gaming operating mode, and (2) an operating mode selector that is coupled to the one or more processing units and has (2A) a virtual fusing register that selects the gaming operating mode for executing the different virtually supported gaming applications, and (2B) a security processor that enables a secure virtual fusing based on documented security files authorizing selection of the gaming operating mode, separately from executing an operating system of the one or more processing units, wherein the gaming operating mode is a reconfigurable operating mode selectable from at least one signed license file of the documented security files.

Secure reconfiguration of hardware device operating features

A secure reconfigurable operating mode system includes a hardware device having multiple operating modes and an operating mode selector that is coupled to the hardware device. The operating mode selector has a virtual fusing register that selects an operating mode for the hardware device and a security processor that enables a secure virtual fusing based on documented security files authorizing selection of the operating mode. A method of secure hardware device operating mode reconfiguration is also provided.

Techniques for selecting a boot display device in the multi-GPU configured computing device include a graphic initialization routine for determining a topology of a plurality of GPUs. It is then determined if a display is coupled to any of the plurality of GPUs. The determination of whether the display is coupled to a GPU is communicated to the other of the plurality of GPUs based upon the determined topology. Thereafter, selection of a given GPU as a primary boot device, by a system initialization routine, is influenced by representing each GPU not coupled to the display as a graphics device and the GPUs coupled to a given display as the primary boot device if one or more displays are coupled to GPUs, and by representing the given GPU as the primary boot device and all other GPUs as graphics devices when the display is not coupled to any of the GPUs. In addition or in the alternative selection of the given GPU as the primary boot device may be influenced by hiding the expansion ROM of GPUs not coupled to a display.
