Abstract: Communication with adapters of a computing environment is facilitated. Instructions are provided that explicitly target the adapters. Information provided in an instruction is used to steer the instruction to an appropriate location within the adapter.

Abstract: Communication with adapters of a computing environment is facilitated. Control instructions specifically designed for communicating data to and from adapters are provided to facilitate the communication. The instructions explicitly target the adapters. Information provided in an instruction is used to steer the instruction to an appropriate location within the adapter, such as a Peripheral Component Interconnect (PCI) or Peripheral Component Interconnect Express (PCIe) adapter.

Abstract: One or more message signaled interruption requests from one or more input/output (I/O) adapters are converted to I/O adapter event notifications. Each I/O adapter event notification includes the setting of one or more specific indicators in system memory and an interruption request, the first of which results in a pending I/O adapter interruption request. While a request for an I/O adapter interruption is pending, subsequent message signaled interruption requests are converted to I/O adapter event notifications, but do not result in additional requests for I/O adapter interruptions.

Abstract: An address provided in a request issued by an adapter is converted to an address directly usable in accessing system memory. The address includes a plurality of bits, in which the plurality of bits includes a first portion of bits and a second portion of bits. The second portion of bits is used to index into one or more levels of address translation tables to perform the conversion, while the first portion of bits are ignored for the conversion. The first portion of bits are used to validate the address.
