  1. Device Fundamentals Overview Windows Logo Program Vinita Tayal Senior Program Manager

  2. Objectives • Role of Device Fundamentals (aka devfund) • Goals of Device Fundamentals • Relationship of devfund requirements & tests to these goals

  3. Overview • What are Device Fundamentals • Details of Device Fundamentals • Summary

  4. Structure of Logo Programs for Hardware

  5. Device Logo Building Blocks Server Client Device Stage Windows Touch Windows Media Center Additional Qualifications  AQ Enabled High Availability Fault Tolerance Dynamic Partitioning Power Management Storage Imaging Graphics Audio Printers Network Bus Display Modem Device-specific Functionality Core functional requirements  Logo • … Device Connectivity • e.g., 1394, PCI, Bluetooth, USB …  Signature Device Fundamentals

  6. Tenets of Device Fundamentals • Baseline quality 25 requirements, 17 tests

  7. Overview • What are Device Fundamentals • Details of Device Fundamentals • Summary

  8. Compatibility NEW

  9. WDF Logo Tests • Targeted for Windows Driver Framework (WDF) drivers • User Mode - UMDF • Kernel Mode - KMDF • Five requirements – DEVFUND-0036 to DEVFUND-0040 • Four tests • ChkINF • WDF Logo test – Final • Verify WDF Co-installer version for UMDF • Verify WDF co-installer version for KMDF • Address compatibility & reliability tenets

  10. Reliability NEW

  11. Stress with IO Tests

  12. IO Cancellation Tests • For proper handling of IO cancellation IRPs • With Driver Verifier ON • With and without real IO data • User scenario • User attempts to cancel a request to an application, and the application hangs • For Windows 7 and later OS • Introduced for “Storage” class devices • Extended to “Network” class devices • Good to know • Crash is a common failure mode • Kernel Debugger – very useful !

  13. Performance NEW

  14. CHAOSConcurrent Hardware and OS test • Tests device/driver capability to support S3 & S4 sleep states • Attempts to see how a driver handles • Power transitions • Plug and Play operations • IO operations Concurrently! • Highly destructive test • Tries to crash a driver • Kernel Debugger

  15. Device Path Exerciser

  16. Security / Stability ALL NEW

  17. Reinstall Tests • Collection of three tests, based on same source • Looks for install issues missed in typical install • Driver Verifier Enabled • Special DV settings for Windows 7 and later • Debugging tips • Kernel Debugger • Setupapi.log , Cbs.log

  18. Availability

  19. Overview • What are Device Fundamentals • Details of Device Fundamentals • Summary

  20. Summary • Device Fundamentals  Baseline quality • Kernel Debugger  Your best friend  • Basic tests  Also available in WDK • Driver Verifier  Use during driver development

  21. References • Overview of Logo Program • What’s New in WLK 1.5 session • Windows Logo Program webcasts http://www.microsoft.com/whdc/winlogo/logocast.mspx • Device Fundamentals Tests • Kernel Debugger Tool

  22. Call To Action • Review Device Fundamentals requirements • Install latest WLK version • Review webcasts • Kernel Debugger Tool • Windows Logo Program Device Fundamentals Tests • Install kernel debugger • Investigate any Device Fundamentals test failures

  23. Feedback • For feedback on the Windows Logo Program or Windows Logo webcasts contact the Logo Team at: logofb@microsoft.com
