    摘要： Particular embodiments described herein provide for an apparatus that includes a means for determining a power state for a device connected to a system, a means for determining that the device should change power states, and means for sending a signal to the device to put the device in a D3-cold state while the system is a GO/SO state. In an embodiment, the device is a peripheral component interconnect (PCI) device. Also, the particular example implementation can include means for sending a WAKE# signal from a controller to the device to cause the device to exit the D3-cold state, wherein the WAKE# signal was sent from a designated WAKE# signal pin on the controller. In some embodiments, the WAKE# signal is not sent to other devices in the system.

    摘要： A method and apparatus is described herein for dynamically allocating resources to root ports. Upon initialization of a system, resources, such as memory space, I/O space, and/or bus numbers are allocated to devices and corresponding windows are assigned to root ports present upstream from those devices. A remaining amount of resources are reserved into a resource pool. When a new device is inserted at runtime, a handler services the insertion notification by assigning an appropriate resource window from the resource pool to the root port upstream from the newly added device. In contrast, upon removal the window of resources are re-assigned back to the resource pool.

    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.
