1. Introduction To The Windows Driver Kit: A Comprehensive Driver Development Solution Lee DavisLead Program ManagerWindows Driver KitsMicrosoft Corporation

2. Session Outline • The WDK tool set for designing, developing, testing, qualifying and deploying drivers • What to do at WinHEC • Get in depth information on tools • Get hands-on experience with the tools • Talk to the experts • Where to get more information on WDK tools

3. The WDK Tool Set • A Comprehensive Solution

4. Test Lab Build Lab Release Team Development Team A Comprehensive Solution Docs Signing Tools Driver Test Manager Driver Verifier Static Analysis Tools Driver Test Framework Build Environments Winqual Integration Docs Signing Tools Samples Windows Driver Framework

5. WDK Docs And Samples • It’s easier to find the information you need • Improved indexing, search and navigation • One-stop shopping • DDK, IFS and HCT docs integrated into one doc set • Samples are searchable • Search multiple external documentation such as MSDN online and Codezone communities

6. Windows Vista Build Environments • The tools, libraries and headers you need to create drivers for Windows Vista • Tools now included in the build environment • PREfast for drivers • Static Driver Verifier (SDV) • DIFx tools • Windows Driver Framework • Windows Driver Test Framework

7. Header Versioning • Build drivers for Windows 2000 forward using one set of headers • Easier to use up level features of later OS environments • Easy to see changes in headers across OS versions • Includes kernel mode and user mode headers

8. Windows Driver Foundation • Simplifies driver development • Replaces complex boilerplate with frameworks • Plug and play and power management abstracted via frameworks • Simplifies creating secure and stable drivers • Quicker development

9. Windows Driver Foundation • Enables moving driver to user mode via User Mode Driver Framework • Headers and libs are included in the WDK build environment • Kernel Mode Driver Framework and UMDF samples are searchable in the docs via WDK help

10. Static Analysis Tools • Enables early detection of complex and difficult to find driver defects • Reduce development time • Create more stable and secure drivers • Reduce test time • Identify critical issues pre-release • Tools included in the WDK • PREfast for Drivers • Static Driver Verifier (SDV) • Automate these tools via the Driver Test Manager (DTM)

11. Driver Verifier • Detecting more defect types • IRP Dispatch • Inconsistent MDL structures • User-mode addresses andother malformed structures • Synch objects in pageable memory • Easier to use • Enable/disable Verifier without rebooting • More flexible Low Resource Simulation behavior

12. Driver Test Manager • The test automation framework used by Microsoft to test Windows • The required test platform for all Windows hardware Logo testing

13. Driver Test Manager • Improved testing throughput • Parallel execution • Automated scheduling and execution of tests • Integrated OS deployment tools • Enables test integration • Use additional Microsoft QA tests • Mix and match Logo, Microsoft QA and your tests to create a custom test pass • Automate tasks such as building drivers, running static analysis and deploying Windows

14. Driver Test Manager • Quick and easy client installs • Remote administration • Create tests • Schedule tests • Deploy operating systems to clients • Review results • Easier collaboration • Easily export tests for use in other labs • Export multiple results and logs to a single CAB • View exported results in a light-weight viewer

15. Driver Test Framework • Frameworks for developing driver tests • DTF is to driver test development what WDF is to driver development • Simplify test development • Enable test developers to focus on device specifics • Write better tests in less time • Create tests that work across multiple devices and device classes

16. Driver Test Framework • Integrates with Driver Test Manager • Headers and libs are included in the WDK build environment • Many of the DTM Logo tests are built on DTF

17. Winqual Integration • Easier testing processes • Automated selection of tests based on device capabilities • Logo Wizard walks you through the process • Status indicator keeps you up to date • Easier submissions • Automated errata and contingency filtering eliminates uncertainty and improves efficiency • Packaging specifically for the simplified Winqual reduces manual processing time • Programmatic collection of data eliminates common errors and ensure a successful submission

18. Signing Tools • Authenticode signing tools now ship in the WDK • Create your own certificates • Create your own catalogs • Sign your own driver catalogs • Trusted by DMI • Required to stop install popup • Trusted by KMCS • Required to load in Vista x64

19. Driver Install (DIFx) Tools • Simplified driver deployment • Simplified driver installation for your customers • Add on to your app installer to install drivers • DIFx tools are included in the WDK build environments
