Software tracing for drivers is usually based on Event Tracing for Windows (ETW), a kernel-level facility that logs trace messages for both kernel-mode and user-mode processes. Because ETW can be somewhat complicated to use, most driver developers use the Windows software trace preprocessor (WPP), which simplifies and enhances the process of instrumenting a driver for ETW tracing.

In this white paper:

  • WPP software tracing basics
  • Trace message functions and macros
  • Supporting software tracing in a driver
  • Tools for software tracing
  • How to run a software trace session
