摘要： A method, apparatus, and computer program product for collecting performance data. In one illustrative embodiment, signaling is performed to start collecting the performance data by an operating system support unit in a multithreaded data processing system. Responsive to a thread switch to an incoming thread after signaling has occurred, the performance data for the incoming thread is collected using a thread specific data collection profile to form collected performance data if the incoming thread is associated with the thread specific data collection profile, wherein the thread specific data collection profile specifies a type of data to collect. Responsive to a subsequent thread switch, the collected performance data is sent to a number of destinations.

摘要： The present disclosure provides a computer program product and activity recording system for identifying idleness in a processor via a concurrent software environment. A thread state indicator records an indication of a synchronization state of a software thread that is associated with an identification of the software thread. A time profiler identifies a processor of the computer system being idle and records an indication that the processor is idle. A dispatch monitor identifies a dispatch of the software thread to the processor. In response to the dispatch monitor determining the indication identifies that the processor is idle and the indication of a synchronization state of the software thread indicating the software thread ceases to execute in the processor, the dispatch monitor generates a record attributing the idleness of the processor to the software thread and the indicated synchronization state.

摘要： A method, apparatus, and computer instructions in a processor for selectively performing operations on data. An operation to be performed on data is identified to form an identified operation. A determination is made as to whether metadata identifying a state of the data is associated with the data. A determination is made as to whether the identified operation can be performed on the data based on the state of the data, in response to the metadata being associated with the data. The operation is performed on the data if the state of the data allows for the operation to be performed. The processor selectively performs the operations based on the state of the data.

摘要： Hardware assist to autonomically patch code. The present invention provides hardware microcode to a new type of metadata to selectively identify instructions to be patched for specific performance optimization functions. The present invention also provides a new flag in the machine status register (MSR) to enable or disable a performance monitoring application or process to perform code-patching functions. If the code patching function is enabled, the application or process may patch code at run time by associating the metadata with the selected instructions. The metadata includes pointers pointing to the patch code block code. The program code may be patched autonomically without modifying original code.

摘要： A computer implemented method, apparatus, and computer usable program code for sampling call stack information. An event is monitored during execution of a plurality of threads executed by a plurality of processors. In response to an occurrence of the event, a thread is identified in the plurality of threads to form an identified thread. A plurality of sampling threads is woken, wherein a sampling thread within the plurality of sampling threads is associated with each processor in the plurality of processors and wherein one sampling thread in the plurality of sampling threads obtains call stack information for the identified thread.

摘要： A method, apparatus, and computer instructions for determining computer flows autonomically using hardware assisted thread stack and cataloged symbolic data. When a new thread is spawned during execution of a computer program, new thread work area is allocated by the operating system in memory for storage of call stack information for the new thread. Hardware registers are set with values corresponding to the new thread work area. Upon context switch, values of the registers are saved in a context save area for future restoration.When call stack data is post-processed, the operating system or a device driver copies call stack data from the thread work areas to a consolidated buffer and each thread is mapped to a process. Symbolic data may be obtained based on the process identifier and address of the method/routine that was called/returned in the thread. Corresponding program flow is determined using retrieved symbolic data and call stack data.
摘要翻译：一种用于使用硬件辅助线程堆栈和编目的符号数据自主地确定计算机流的方法，装置和计算机指令。当在执行计算机程序期间产生新的线程时，操作系统将新的线程工作区分配给存储器，以存储新线程的调用堆栈信息。硬件寄存器设置为与新线程工作区域对应的值。在上下文切换时，寄存器的值保存在上下文保存区域中，以备将来恢复。当调用堆栈数据进行后处理时，操作系统或设备驱动程序将调用堆栈数据从线程工作区域复制到统一缓冲区，并将每个线程映射到进程。可以基于在线程中调用/返回的方法/例程的进程标识符和地址获得符号数据。使用检索到的符号数据和调用堆栈数据确定相应的程序流程。
