CPU Function Trace Analysis and Kernel Stack Overview

This document details the analysis of CPU function traces and associated kernel stack activities. It focuses on a specific event identified by an ID and records various parameters related to CPU operations, including ticks, counts, and function calls. The recorded functions illustrate the interactions at the driver and kernel interface, providing insights into system performance and potential areas of optimization. Key functions like `ddi_get16`, `nge_check_copper`, and `av_dispatch_softvect` are discussed, showcasing their roles within the kernel's operation during the monitored period.
