Abstract: A tracing and debugging system may collect both performance related tracer data and snapshot data. The tracer data may contain aggregated performance and operational data, while the snapshot data may contain call stack, source code, and other information that may be useful for debugging and detailed understanding of an application. The snapshot data may be stored in a separate database from the tracer data, as the snapshot data may contain data that may be private or sensitive, while the tracer data may be aggregated information that may be less sensitive. A debugging user interface may be used to access, display, and browse the stored snapshot data.

Abstract: Method for providing precise microprocessor performance counter readings including detecting a swap back to a monitored process executing in a microprocessor. In response to the detected swap back to the monitored process, if the value read from the performance counter does not exceed the defined overflow threshold, the value of the performance counter stored in the first memory location is restored to the performance counter. If the value read from the performance counter exceeds the defined overflow threshold, the performance counter is set to zero and the value of the performance counter stored in the first memory location is used to increment an overflow memory location. If the value read from the performance counter exceeds the defined overflow threshold, at least one performance counter reading instruction is detected and in response to the detected at least one performance counter reading instruction, setting the counter output register to zero.

Abstract: A system monitors data accesses to specific rows of memory to determine if a row hammer condition exists. The system can monitor accessed rows of memory to determine if the number of accesses to any of the rows exceeds a threshold associated with risk of data corruption on a row of memory physically adjacent to the row with high access. Based on the monitoring, a memory controller can determine if the number of accesses to a row exceeds the threshold, and indicate address information for the row whose access count reaches the threshold.

Abstract: A system for providing performance counter inheritance includes an operating system that receives a request of a first application to monitor performance of a second application, the request identifying an event to monitor during the execution of a task associated with the second application. The operating system causes a task counter corresponding to the event to be activated, and automatically activates a child task counter for each child task upon receiving a notification that execution of a corresponding child task is starting. Further, the operating system adds a value of each child task counter to a value of the task counter to determine a total counter value for the task, and provides the total counter value of the task to the first application.

Abstract: The present technology monitors events that allocate and deallocate virtual memory regions in a device, wherein the events include system calls from user space. The system can generate a log of events, and based on the log of events, track regions of virtual memory allocated and deallocated via the events. The system can also record events with corresponding stack traces. Next, the system can group recorded events having matching stack traces to yield event groupings, and instrument functions in a compiled code associated with the process to determine retain counts of respective events associated with the functions. The system can then automatically pair at least one of a first portion of the events and a second portion of the respective events based on the event groupings and the retain counts of the respective events to yield paired events.
