摘要： Aspects of the embodiments include systems, methods, devices, and computer program products to receive, from the downstream component, an indication of an extended capability; determining, from the indication, one or more configuration parameters for the downstream component; applying the one or more configuration parameters; and performing data signal or control signal transmissions across the PCIe-compliant link with the downstream component based, at least in part, on the applied one or more configuration parameters. The extended capabilities can be indicated by a DVSEC extended capability definition received from a downstream device. The extended capabilities of the downstream component can indicate the number of buses, the port type, the expandability capability, the D3Cold support status, the host router indicator, and/or the safe eject requirements of the downstream component.

摘要： Embodiments of computer-implemented methods, systems, computing devices, and computer-readable media are described herein for transitioning a computing device between a first state in which the computing device uses a first amount of power and a second state in which the computing device uses a second, greater amount of power. The computing device may include a shared wake pin to which a first external device and a second external device may be operably coupled, and a communication bus to which the first external device is connected and the second external device is not. Responsive to receipt of a wake signal at the wake pin, the computing device may transition between states, send an instruction to the first external device over the communication bus, and determine whether the first or second external device initiated the wake signal based on a response at the wake pin.

摘要： Techniques for determining a communication interface of a computer platform. In an embodiment, a power management unit of a computer platform provides to an agent of the platform an indication of a power state. In certain embodiments, the agent determines, based on the indication of the power state, that an interface is expected to be available. The agent may designate information for transmission via the first interface—e.g. in lieu of transmitting the information via a second interface which is available prior to the first interface becoming available.

摘要： An embodiment may include circuitry that may generate and/or use, at least in part, at least one descriptor to be associated with at least one packet. The at least one descriptor may specify at least one transmission time at which the at least one packet is to be transmitted. The at least one transmission time may be specified in the at least one descriptor in such a manner as to permit the at least one transmission time to be explicitly identified based at least in part upon the at least one descriptor. Many alternatives, modifications, and variations are possible without departing from this embodiment.

摘要： A system can include a host machine connected to a device under test (DUT) by a serial link. The host machine can include a serial interface, such as a Thunderbolt interface, and a memory. The DUT can include a trace data source, a high-speed trace interface (HTI) to receive trace data from the trace data source, a serial interface (such as a Thunderbolt interface), and a PIPE interface connecting the HTI with the serial interface. The HTI is to send the trace data to the serial interface through the PIPE interface. The serial interface is to packetize the trace data into a conforming packet format, and send the trace data as a packet across the serial link to the host machine. The host machine can receive the trace data at the host-side serial interface, store the trace data in memory, and process the trace data for debugging the DUT.

摘要： Buses such as USB4 or Thunderbolt 4 buses may allow for device combinations that actually cannot be accommodated on the bus. A monitoring component, e.g., software and/or hardware component, such as an Operating System (OS) policy manager, may monitor a bus for events identifying changes to devices on the bus. The monitoring component may influence mode changes to hardware/software, such as to the USB configuration, device driver settings, attached device settings, and/or settings for devices attaching to the bus. Influenced changes facilitate accommodating changes to the devices attached to the bus. For example, if a display is attached and it would exceed available bus bandwidth, cause an excess system load, or cause some other problem, rather than fail to enumerate the display, instead hardware and/or software associated with the bus may be influenced to result in a resolution reduction for the display to accommodate it attaching to the bus.

摘要： 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.
