International Classification:

G06F 13/26
G06F 13/42

Abstract:

Device virtualization techniques can enable physical I/O devices (such as PCIe devices or other I/O devices) to appear as virtual I/O devices, while also enabling selective exposure of information regarding the physical I/O devices to enable the native drivers of the physical I/O devices to be run. In one example, one or more physical I/O devices associated with a virtual I/O device are locked, and an interface is monitored for requests to those physical I/O devices. The device can be unlocked in response to a request to a predetermined address. When a physical I/O device is locked, read requests to read an identifier of the physical device are blocked, and a value associated with the virtual I/O device is provided. When the physical I/O device is unlocked, read requests to read an identifier of the physical I/O device are forwarded to the physical I/O device.

International Classification:

G06F 1/26

Abstract:

Three components are used to adjust the CPU peak power based on the USB TYPE-C device states. These components include operating system (OS) Peak Power Manager, USB TYPE-C Connector Manager, and USB TYPE-C Protocol Device Driver. The USB TYPE-C Connector Manager sends a synchronous request to the OS Peak Power Manager when a USB TYPE-C power sink device is attached or detached, and the USB TYPE-C Protocol Device Driver sends a synchronous request to the Peak Power Manager when the power sink transitions device state. The Peak Power Manager takes power budget from the CPU when the USB TYPE-C connector is attached to a power sink and is active (e.g., high power device state), and gives back the power budget to the CPU for performance when the USB TYPE-C connector is either detached or the attached and power sink device is idle (lowest device state).

International Classification:

G06F 9/4401
G06F 13/38
G06F 1/3215

Abstract:

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.

International Classification:

G06F 1/329
G06F 1/3287
G06F 1/3228
G06F 1/26

Abstract:

Embodiments may include systems and methods for communication including a communication port with a first lane and a second lane, a first power controller and a second power controller coupled to the communication port. The first power controller is to control, at a first time instance, the first lane to operate in a first power state selected from a first set of power states for the first lane. The second power controller is to control, at a second time instance, the second lane to operate in a second power state selected from a second set of power states for the second lane, wherein the first power state is different from the second power state. Other embodiments may be described and/or claimed.

International Classification:

G06F 9/445
G06F 13/10
G06F 13/42

Abstract:

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.
