Windows Performance Toolkit (WPR-WPA-Xperf) Basics - Focusing in DPC/ISR Captures & Analysis
In this video, my primary focus revolves around the measurement of execution time or latency of drivers, and by extension, the DPC & ISR mechanisms. Concurrently, I also introduce some fundamental aspects that one must be acquainted with in order to effectively utilize the tools provided by the Windows Performance Toolkit. Lastly, for any remarks, disagreements, or observations, please do not hesitate to bring them to my attention through any means available.
