Abstract: Technologies for virtual general purpose I/O (GPIO) include a computing device having a virtual GPIO controller driver, a virtual GPIO controller firmware interface, and a virtual GPIO controller. The driver receives a GPIO command from an operating system of the computing device. The GPIO command specifies an operation to be performed by a GPIO pin. The driver sends the GPIO command to the firmware interface. In response to the firmware interface receiving the command, the virtual GPIO controller emulates a virtual GPIO pin to implement the GPIO command. The firmware interface may trigger an interrupt that can be received by the operating system. The virtual GPIO controller may emulate the virtual GPIO pin using firmware-reserved backing memory, an embedded controller, or an interface to a peripheral device of the computing device. The firmware interface may be an ACPI control method. Other embodiments are described and claimed.

Abstract: A system on a chip (SoC) is provided with a multicore processor, a level-2 (L2) cache controller, an L2 cache, an integrated memory controller, and a serial point-to-point link interface to enable communication between the multicore processor and a device. The interface implements a protocol stack and includes a transmitter to transmit serial data to the device and a receiver to deserialize an incoming serial stream. The protocol stack supports a plurality of power management states, including an active state, a first off state, in which a supply voltage is to be provided to the device, and a second off state, in which the supply voltage is not to be provided to the device. In response to an indication the device is ready to enter the active state, the protocol stack provides for accessing the device prior to expiration of a default recovery time to complete the transition.

Abstract: A serial point-to-point link interface to enable communication between a processor and a device, the high speed serial point-to-point link interface including a transmitter to transmit serial data, a receiver to deserialize serial data, and control logic to implement a protocol stack. The protocol stack supports a plurality of power management states, including an active state, a first off state, in which a supply voltage is maintained, and a second off state, in which the supply voltage is not to be provided to the device. The protocol stack provides a default recovery time to allow the device to begin a transition from the first off state to the active state prior to accessing the device. The protocol stack further provides for accessing the device prior to expiration of the default recovery time to complete the transition based on a device-advertised recovery time.

Abstract: A system on a chip (SoC) is provided including processing cores and a root complex. The transaction requests are communicated between a root port of the root complex and a device, the root port including electrical idle (EI) exit detect circuitry and a reference clock source. The root port supports a first link state, in which the reference clock source and EI exit detect circuitry of the root port are disabled but a common mode voltage is maintained, and a second link state, in which the reference clock source and EI exit detect circuitry are disabled and the common mode voltage is not maintained. The root port transitions to the first link state based on a service latency requirement of the device being less than a threshold and to the second link state based on the service latency requirement being greater than or equal to the threshold.
