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. When a hypervisor signals that a task is being resumed, 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 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 taken branches in a current trace and may use branch prediction success to determine whether to collect a predicted and taken branch instruction in a current trace or to start a new segment when the branch resolves in a non-predicted direction.

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： A method of data processing includes a processor of a data processing system executing a controlling thread of a program and detecting occurrence of a particular asynchronous event during execution of the controlling thread of the program. In response to occurrence of the particular asynchronous event during execution of the controlling thread of the program, the processor initiates execution of an assist thread of the program such that the processor simultaneously executes the assist thread and controlling thread of the program.
