摘要： An I/O device obtains multiple unique N_Port IDs (identifiers) for a NPIV N_Port ID Virtualization (NPIV) capable physical adapter. Fabric management routines are able to assign the multiple unique N_Port IDs to distinct fabric zones. LUNs (logical unit numbers) are able to be associated with the multiple unique N_Port IDs such the LUNs associated with unique N_Port ID do not exceed a limitation. The I/O device is able to associate different resources with different unique N_Port IDs to limit the scope of actions of one or more hosts. The I/O device is able to configure one or more LUNs by the multiple unique N_Port IDs to control access. Different unique N_Port IDs are able to be configured to have different quality of service attributes and/or different levels of security. The I/O device may include multiple independent logical partitions (LPARs) and assign each multiple unique N_Port IDs.

摘要： Occurrences of a particular event in an electronic device are counted by incrementing an event counter each time a variable number of the particular events have occurred, and automatically increasing that variable number as the total count increases. The variable number (prescale value) can increase geometrically according to a programmable counter base each time the count mantissa overflows. The event counter thereby provides hardware-implemented automatic prescaling while significantly reducing the number of interface bits required to support very large count ranges, and retaining high accuracy at very large event counts.

摘要： Techniques for simulating exclusive use of a processor core amongst multiple logical partitions (LPARs) include providing hardware thread-dependent status information in response to access requests by the LPARs that is reflective of exclusive use of the processor by the LPAR accessing the hardware thread-dependent information. The information returned in response to the access requests is transformed if the requestor is a program executing at a privilege level lower than the hypervisor privilege level, so that each logical partition views the processor as though it has exclusive use of the processor. The techniques may be implemented by a logical circuit block within the processor core that transforms the hardware thread-specific information to a logical representation of the hardware thread-specific information or the transformation may be performed by program instructions of an interrupt handler that traps access to the physical register containing the information.

摘要： Multiple machine state registers are included in a processor core to permit distinction between use of hardware facilities by applications, supervisory threads and the hypervisor. All facilities are initially disabled by the hypervisor when a partition is initialized. When any access is made to a disabled facility, the hypervisor receives an indication of which facility was accessed and sets a corresponding hardware flag in the hypervisor's machine state register. When an application attempts to access a disabled facility, the supervisor managing the operating system image receives an indication of which facility was accessed and sets a corresponding hardware flag in the supervisor's machine state register. The multiple register implementation permits the supervisor to determine whether particular hardware facilities need to have their state saved when an application context swap occurs and the hypervisor can determine which hardware facilities need to have their state saved when a partition swap occurs.

摘要： A performance monitoring technique provides task-switch immune operation without requiring storage and retrieval of the performance monitor state when a task switch occurs and provides accurate performance monitoring information. When a hypervisor signals that a task is being resumed and the application privilege level has been entered, it provides an indication, which starts a delay timer. The delay timer is resettable in case a predetermined time period has not elapsed when the next task switch occurs. After the delay timer expires, analysis of the performance monitor measurements is resumed, which prevents an initial state, a state due to execution of the operating system or hypervisor, or a state remaining from a previous task from corrupting the performance monitoring results. The performance monitor may be or include an execution trace unit that collects branch information in a current program execution trace.

摘要： An apparatus and computer program are disclosed for collecting data about the transmission of network packets that are associated with specified applications. The packets are transmitted through a communications network fabric that is used to couple data processing systems together. A particular existing single bit in a frame header definition is selected. The bit is defined as part of the standard frame header by a communication protocol as an available bit in the frame header. The standard protocol is unchanged by the selection of this bit. An application is specified to be monitored. The selected bit is then set in each network packet that is generated by the specified application. The fabric collects performance data for each packet that has the bit set. Thus, the fabric collects performance data about a transmission of each packet that is generated by the application when that application is setting the bit.

摘要： A system for supervisor partitioning of client resources in a subnet communications environment includes a plurality of client nodes, each receiving an allocated set of resources determined by a central authority, which assigns resources to a supervisor key associated with each supervisor of the plurality of client nodes. At each of the client nodes, the allocated set of resources are partitioned using a local supervisor associated therewith, with each supervisor associating one or more resource keys with one or more resources allocated to the corresponding client node, and assigning the one or more resource keys to the one or more applications. The supervisor keys are configured so as to prevent a given supervisor from partitioning resources not allocated to the client node associated therewith. Following the partitioning, communication packets are issued from the one or more applications to a resource provider node without inspection by the corresponding supervisor.
