Abstract:
Eine abflachende Portalbrücke (FPB) wird bereitgestellt, um das Adressieren gemäß einem ersten Adressiersystem und einem zweiten, alternativen Adressiersystem zu unterstützen. Die FPB umfasst eine Primärseite und eine Sekundärseite, wobei die Primärseite mit einem ersten Satz von Bauteilen verbindet, der gemäß einem ersten Adressiersystem adressiert ist, und die zweite Seite mit einem zweiten Satz von Bauteilen verbindet, der gemäß einem zweiten Adressiersystem adressiert ist. Das erste Adressiersystem verwendet eine einzige Busnummer innerhalb eines Bus-/Bauteil-/Funktion (BDF)-Adressraums für jedes Bauteil in dem ersten Satz von Bauteilen, und das zweite Bus Adressiersystem verwendet eine einzige Bus-Bauteilnummer für jedes Bauteil in dem zweiten Satz von Bauteilen.
Abstract:
método, aparelho e sistema para a melhora dos tempos de retomada das portas raiz e dos pontos de extremidade integrados às portas raiz. a presente invenção refere-se a um dispositivo que é determinado para ficar em um estado de baixa energia. uma transição de um estado de baixa energia para um estado ativado é iniciada; nela um tempo mínimo de retomada, fixo, é definido para transições do estado de baixa energia para o estado ativado. um recurso do dispositivo é identificado correspondendo à transição do dispositivo de um estado de baixa energia para o estado ativo, e a transição do dispositivo de um estado de baixa energia para um o estado ativo é completada com base em pelo menos parte do recurso, de modo que a transição seja concluída antes de expirado o tempo mínimo de recuperação fixado

Bei einer offenbarten Ausführungsform können Daten, die einer Leerlaufzeit für ein oder mehrere Downstream-Geräte entsprechen, empfangen werden. Energie kann zumindest teilweise basierend auf den empfangenen Daten geregelt werden. Weitere Ausführungsformen werden ebenfalls offenbart.
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:
An electronic device may be provided that includes a first controller, a second controller, and a bus to connect between the first controller and the second controller. The electronic device may also include a first signal line between the first controller and the second controller, and the first controller to provide a first signal on the first signal line to the second controller to wake up the second controller from a low power mode.
Abstract:
A method and apparatus to reduce the idle link power in a platform. In one embodiment of the invention, the host and its coupled endpoint(s) in the platform each has a low power idle link state that allows disabling of the high speed link circuitry in both the host and its coupled endpoint(s). This allows the platform to reduce its idle power as both the host and its coupled endpoint(s) are able to turn off their high speed link circuitry in one embodiment of the invention.
