Tracing and Diagnosability for WDF Drivers
Updated: October 23, 2008
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. This paper discusses how to implement WPP tracing in a Windows Driver Foundation (WDF) driver.
This information applies for the following operating systems:
Windows Server 2008
Windows Vista
Windows Server 2003
Windows XP
Windows 2000
