Abstract: Some examples described relate to securing a memory device of a computing system. For instance, a method may comprise comparing a command for the memory device to each command in a list of commands. The command is accepted when the command matches an authorized command in the list of commands. The accepted command is issued to the memory device.

Abstract: Various examples described herein provide for a management controller that includes a virtual universal serial bus (USB) host controller that can emulate an actual USB host controller to a central processor. A particular endpoint from a number of endpoints is associated with a virtual USB device that is coupled to the virtual USB host controller. The particular endpoint is to refer to a location in a management memory.

Abstract: A method performed by a physical computing system, the method includes disabling a display refresh process of a video controller of the physical computing system if no active display device is connected to the physical computing system. A physical computing system includes a video controller comprising a rendering engine and a display refresh controller; a memory controller connected to a memory; and a display controller to determine whether an active display device is connected to the physical computing system; in which a display refresh process performed by the display refresh controller is disabled when no active display device is connected to the physical computing system.

Abstract: A process includes emulating, by a programmable logic device, a hardware component to provide an emulated hardware component. The emulated hardware component is capable of exercising the predetermined functionality. The process includes testing the emulated hardware component. The process includes determining, by the programmable logic device, whether the emulated hardware component exercised the predetermined functionality during the test. The determination includes, responsive to the testing, detecting, by a state sequence detector of the programmable logic device, whether the emulated hardware component sequenced through a plurality of states associated with the predetermined functionality. The process includes, responsive to the detection of whether the emulated hardware component sequenced through the plurality of states, generating, by the programmable logic device, an indicator representing a coverage of the predetermined functionality by the testing.

Abstract: A process includes, responsive to a primary power source being enabled, receiving, from a real time clock (RTC) device of a computer platform, an indication of a first time. Responsive to the primary power source being enabled, the process includes storing first data in a first non-volatile storage of the computer platform representing a snapshot of the first time and repeatedly updating the snapshot to cause the snapshot to track the first time. Responsive to the primary power source being disabled to begin a power outage, the process includes providing, by a timer of the computer platform powered by a secondary power source, a timer output that represents an accumulated time that corresponds to the power outage. The process includes restoring a state of the RTC device responsive to the primary power source being reenabled to end the power outage. The restoration includes, based on the accumulated time and the snapshot, determining a second time, and storing second data in the RTC device that represents the second time.

Abstract: An apparatus includes a subsystem, a first processor, a memory, a circuit and a second processor. The first processor is to execute bootstrap instructions, and the memory is to store second instructions. The circuit is to hold the first processor in reset in response to the apparatus being powered on; and the second processor is to, while the first processor is held in reset, execute the second instructions to initialize the subsystem.

Abstract: A technique includes a baseboard management controller receiving, from a requestor, a request for a security function to be performed, where the request is directed to a physical security device other than the baseboard management controller. The technique includes, the baseboard management controller responding to the request to emulate a response to the security device to the request.

Abstract: An apparatus includes a plurality of subsystems, including a first subsystem and a second subsystem. The apparatus includes a master processor to, in response to a power on of the apparatus, execute first instructions to configure the first subsystem and provide second instructions. The apparatus further includes a slave processor to, prior to the boot of the apparatus, receive the second instructions from the master processor and execute the second instructions to configure the second subsystem.

Abstract: A method for assembling a computing device including initiating a board management controller of the computing device, the board management controller having at least one fuse, forming data to control a video display operatively connected to the computing device to show an image of a watermark, and modifying the computing device. The method also includes blowing the at least one fuse in response to modifying the computing device and adjusting the watermark in response to blowing the at least one fuse.
