ABSTRACT:
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.
