Abstract: A measurement facility is provided for capturing and presenting fine-grained usage information for adapter functions in an input/output subsystem. Adapter specific input/output traffic is tracked on a per function basis and the results are dynamically presented to the user. This information is useful for performance tuning, load balancing and usage based charging, as examples.

Abstract: An adapter is enabled for use. The enabling includes assigning one or more address spaces to the adapter, based on a request. For each address space assigned to the adapter, a corresponding device table entry is assigned. When the adapter is no longer needed, it is disabled and the assigned device table entries become available.

Abstract: A method and system for a distributed computing system having components like end nodes, switches, routers and links interconnecting packets over the interconnecting links. The switches and routers interconnect the end nodes and route the packets to the appropriate end node. The end nodes reassemble the packets into a message at a destination. A mechanism is provided to allow a single physical component to appear as multiple components each with unique control levels. These components may be host channel adapters (HCAs), target channel adapters (TCAs) or switches. A method and system for end node partitioning for a physical element is provided. A configuration of the physical element is selected. A port associated with the physical element is probed, wherein the port is probed with a subnet management packet by a subnet manager. In response to detecting a switch associated with the port, a local identifier is assigned to the port resulting in a configuration change of the physical element.

Abstract: método, equipamento, programa de computador e produto de programa de computador para controle de acesso a adaptadores num ambiente computacional o acesso a um adaptador de entrada/saída por configuração é controlado. para cada acesso solicitado ao adaptador, são feitas verificações para determinar se a configuração está autoriza-da a acessar o adaptador. se não estiver autorizada, então o acesso é negado. se estiver auto-rizada, mas o acesso estiver temporariamente bloqueado, a instrução de execução é alterada para indicar isso. se o acesso for permitido, mas o acesso deva ser bloqueado por outra razão (diferente do bloqueio temporário), 10 então o acesso é negado.

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.

IPC: G06F9/48

Abstract: The conditions under which adapter interruptions are made pending are controlled. Responsive to an interruption being presented to an operating system, subsequent interruptions are suppressed on all central processing units in the configuration. The operating system processes the interruption, including examining and processing indicators of reported events until the operating system discontinues the suppression. This enables the operating system to control the number of pending interruptions and the number of processors processing those interruptions.

Abstract: Communication with adapters of a computing environment is facilitated. Control instructions specifically designed for communicating data to and from the 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) adapter or a Peripheral Component Interconnect Express (PCIe) adapter.
