摘要： A distributed power management technique allows controlling power states of devices separated from a power management controller, such as a processor, by an interconnect. The power management controller inserts power state information into an interconnect transaction. An interconnect connected device then extracts the power state information and modifies the power state of the device responsive to the power state information. The power state information can be extracted by a processor that then controls the power state of another device responsive to the power state information.

摘要： Distributed peer-to-peer transactions are defined on an interconnect bus of a computer system according to an interconnect protocol. The transactions contain a completer device attribute data and a self-defining payload data. The transaction is identified as a peer-to-peer transaction by a command or an attribute data in the transaction. The transaction can be routed across a hierarchy of interconnect bus segments using the completer device address data. A handle can be used by an operating system of the computer system to indicate permission for the peer-to-peer transaction. Address information in a completer device address space can be provided within the peer-to-peer transaction or by a completer device driver for use by the completer device in processing the peer-to-peer transaction.
