Techniques for implementing improved USB redirection of USB HID class devices are provided. In one set of embodiments a client system can receive, from a virtual desktop running on a server system, a poll message directed to an HID interface of a USB HID class device plugged into the client system and identify a polling thread associated with the HID interface. The client system can further save a copy of the poll message in the polling thread and initiate local polling of the HID interface, where the local polling comprises providing, via the polling thread, the copy of the poll message to the HID interface.

A computer aided instruction system includes a keyboard driver and an instruction renderer. The keyboard driver is configured to retrieve a keyboard input from a user before the application receives the keyboard input, and the instruction renderer is configured to execute a computer aided instruction tutorial to instruct the user to input a specific key or key combination. The keyboard driver is further configured to transmit the keyboard input to the instruction renderer to evaluate whether the one or more keystrokes matches the specific key or key combination.

Automatic-switching and deployment of software (SW)- or firmware (FW)-based USB4 connection managers (CMs) and associated methods, apparatus, software and firmware. A handshake is defined between BIOS and an operating system (OS) to discover supported CM capability and dynamically switch from a FW CM to a SW CM and visa verse if there is a mismatch. In addition, a mechanism is defined to deploy the correct FW or SW CM driver based on class code, 2-part or 4-part ID. Support for continued USB4 operation during an OS upgrade or downgrade is provided, while ensuring that the best possible CM solution is used based on the advertised platform and OS capability. USB4 controllers support a pass-through mode under which the host controller FW redirects control packets sent between an SW CM and a USB4 fabric, and a FW CM mode under which control packets are communicated between the host controller FW and the USB4 fabric to configure USB4 peripheral devices and/or USB4 hubs in the USB4 fabric.

Provided herein is a moving object simulation method including: a simulation preprocessing step in which a first server generates environment information for the simulation target, including at least one of road data, nearby vehicle data, nearby pedestrian data, nearby obstacle data, nearby traffic light data, nearby sign data, and event data, for a predetermined period of time; and a simulation step in which a second server calculates sensor unit output data of a simulation target vehicle according to movement of the simulation target vehicle for the predetermined period of time using the environment information, preventing computational overload due to limitations of server resources and promoting quality improvement for algorithm verification.

A method is provided to generate a configuration descriptor for a chipset in a computing unit. The method includes determining, by one or more processors, a plurality of desired interface configurations for the chipset and for each of the one or more desired interface configurations, determining one or more ports of the chipset and corresponding platform connectors that satisfy features of the each of the one or more of the desired interface configurations based on a chipset description and a platform description. The method further includes assigning a port from among the determined one or more ports to the each of the one or more of the desired interface configurations and generating a chipset configuration descriptor based on the assigning of ports to each of the one or more desired interface configurations. In some embodiments, the chipset is initialized based on the configuration descriptor.

System and method for providing trusted execution environments uses a peripheral component interconnect (PCI) device of a computer system to receive and process commands to create and manage a trusted execution environment for a software process running in the computer system. The trusted execution environment created in the PCI device is then used to execute operations for the software process.

A method of configuring a display device interface (DDI) detects a trigger signal, generated by a display device. If the trigger signal is associated with a power on event, a full configuration of the DDI is performed, including loading display device capability information provided by the display device into DDI configuration registers and setting one or more DDI configuration parameters accordingly. If the trigger signal is associated with resume event, rather than a power on event, a modified fast link resume operation may be performed to route the trigger signal to a controller configured to explicitly write display device capability information to the appropriate DDI configuration registers before setting the corresponding DDI configuration parameter accordingly. The DDI may include a re-timer, between the DDI source and sink, configured to snoop the explicit write transaction such that the re-timer configuration is also updated.

Examples disclosed herein provide the ability for a computing device to adjust settings on a computing device. In one example method, the computing device captures, via a first sensor of a computing device, images of an environment that the computing device is currently in, and detects objects in the environment as captured by the images. As an example, the computing device determines a location of the environment based on contextual data gathered from the detected objects and adjusts a setting on the computing device based on the determined location.

Apparatus and methods for managing power consumption of a data-path in a computer system are provided, the data-path comprising a first port and a second port, the first port comprising a high-speed and the second port comprising a low-speed port. The disclosed method including connecting a device to the data-path, determining that the connected device is to communicate using the second port and turning off an active circuit associated with the first port of the data-path.

Systems, apparatuses, methods, and computer-readable media are provided for device interface management. A device includes a device interface, a virtual machine (VM) includes a device driver, both to facilitate assignment of the device to the VM, access of the device by the VM, or removal of the device from being assigned to the VM. The VM is managed by a hypervisor of a computing platform coupled to the device by a computer bus. The device interface includes logic in support of a device management protocol to place the device interface in an unlocked state, a locked state to prevent changes to be made to the device interface, or an operational state to enable access to device registers of the device by the VM or direct memory access to memory address spaces of the VM, or an error state. Other embodiments may be described and/or claimed.
