US Patent 11231987 Debugging of memory operations

A debugging tool, such as may take the form of a software daemon running in the background, can provide for the monitoring of utilization of access mechanisms, such as Direct Memory Access (DMA) mechanisms, for purposes such as debugging and performance improvement. Debugging tools can obtain and provide DMA utilization data, as may include statistics, graphs, predictive analytics, or other such information. The data can help to pinpoint issues that have arisen, or may arise, in the system, and take appropriate remedial or preventative action. Data from related DMAs can be aggregated intelligently, helping to identify bottlenecks where the individual DMA data might not. A debugging tool can store state information as snapshots, which may be beneficial if the system is in a state where current data is not accessible. The statistics and predictive analytics can also be leveraged to optimize system-performance.
