Abstract: In some examples, a device includes a processor, a core hardware logic to execute instructions to perform a task in the device, and a controller separate from the processor. The controller detects corruption of the instructions, and in response to detecting the corruption, load a recovery code to the core hardware logic to trigger recovery of the core hardware logic from the corruption of the instructions.

Abstract: A computer system is monitored by firmware for a non-conforming state. Upon detecting the non-conforming state, firmware of the computer system outputs a keyboard code that causes an operating system to enter a predetermined state, such as a lock screen or other quiescent display state. A human-perceptible message is displayed at a display device after outputting the keyboard code.

Abstract: An autonomous driving system could create or exacerbate a hazardous driving situation due to incorrect machine learning, algorithm design, sensor limitations, environmental conditions or other factors. This technology presents solutions that use machine learning to detect when the autonomous driving system is in this state e.g., erratic or reckless driving and other behavior, in order to take remedial action to prevent a hazard such as a collision.

Abstract: In an example implementation according to aspects of the present disclosure, a method may include receiving by a controller a BIOS image, extracting a current manufacturing programming mode state corresponding to a computer system. A BIOS personality of the BIOS image is evaluated, wherein the BIOS personality is based on a differentiation of hardware and software functionality. Based on the current manufacturing programming state and the BIOS personality, a compatibility with the computer system is determined. Based on the compatibility, the BIOS image is written to non-volatile memory.

Abstract: In various examples, motifs, watermarks, and/or signature inputs are applied to a deep neural network (DNN) to detect faults in underlying hardware and/or software executing the DNN. Information corresponding to the motifs, watermarks, and/or signatures may be compared to the outputs of the DNN generated using the motifs, watermarks and/or signatures. When a the accuracy of the predictions are below a threshold, or do not correspond to the expected predictions of the DNN, the hardware and/or software may be determined to have a fault—such as a transient, an intermittent, or a permanent fault. Where a fault is determined, portions of the system that rely on the computations of the DNN may be shut down, or redundant systems may be used in place of the primary system. Where no fault is determined, the computations of the DNN may be relied upon by the system.

Abstract: According to one example, to access at least one computer device from a virtual machine, a control domain accesses a list of at least one device. For each device in the list of devices, a determination is made as to whether the device is to be exposed to a virtual machine, and a table of devices determined to be exposed to the virtual machine is created and provided to the virtual machine. Determining whether a device is to be exposed to a virtual machine is based on at least one device attribute.
