Abstract: Systems and methods are disclosed for logging encoded diagnostic information from a sequence of processing operations, the processing operations generated by an activity in a computing environment. Diagnostic information is tracked by activity, across process boundaries where the processes can be in computationally isolated, or “sandboxed”. Within each process, diagnostic information for an activity is stored in an activity-specific buffer registered with a kernel in the computing environment. For each activity in the computing system, the kernel keeps a list of all processes that have performed, or are performing, a processing task of the activity. The kernel also keeps a reference to the activity-specific log buffers for the activity for each process associated with the activity. If a processing operation for an activity fails, all activity-specific logs from all processes that are associated with the activity can be collected. A report can be generated from the collected logs for the activity.

Abstract: A method and an apparatus for a power assertion management are described. A power assertion indicator may be maintained for a device component having a power level. The power assertion indicator can indicate whether the power level of the device component is allowed to be lowered. A power assertion request may be sent from a first process to prevent lowering the power level of the device component before a data processing task is completed. A second process can receive a request from the first process to perform operations for the data processing task. The power level of the device component may not be allowed to be lowered before the second process completes the operations for the data processing task. The power level of the device component may be lowered after the data processing task is completed.
