  1. IEEE-1394 Kashif Hasan Test Developer, NT Base Test Team

  2. Agenda • IEEE-1394 Core Driver Stack • Test Cases • How To Report Bugs • Debugging and Triage Tips • Q & A

  3. etc. Scanning MSDV.SYS Printing IP1394 Storage Driver AVC.SYS Stack 61883.SYS SBP2PORT.SYS IRP-Based Interface 1394BUS.SYS IRP-Based Interface OHCI1394.SYS IEEE-1394 Core Stack Core Stack: 1394BUS.SYS, OHCI1394.SYS Client Drivers: 61883.SYS, AVC.SYS, SBP2PORT.SYS, Other 3rd-party Drivers, etc.

  4. 1394 Support in Windows • Inbox support for: • 61883 Devices (AVC command set and Tape and Camera Subunits) • SBP-2 Devices (using SCSI Command Set) • 1394 DCam (conferencing cameras) • IP (v4) over 1394

  5. Test Cases • Plug and Play • Hot-Plug / Hot-Unplug / Surprise Remove • Disable / Enable • Remove / Refresh • Power Management • S1, S3 and S4 System Power States • D0 and D3 System Power States • Data transfer while transition

  6. Test Cases (cont.) • 1394 Tests • Transmitting while generating bus resets • Enumerate and work with in-box class drivers • Verify Gap Counts optimizations • Interoperability • Multiple devices, Multiple PCs • Different tree topologies • Force various Root and Bus Manager node

  7. How To Report Bugs • Clear repro steps • What hardware is used, bus topology info • Version info (OS, hardware revision, firmware, etc.) • Expected behavior • How often does this repro? • Exact behavior which causes the issue • Identify which devices(s) cause this

  8. How To Report Bugs • Please Repro with Checked Binaries with debug spew and Driver Verifier Enabled • Regression / Repro Information • Is this new? (Regression Steps) • Did this happen in previous build, beta, OS ver? • Does this happen with other devices? • Other devices of same or other classes • Different Host Controller / Device Topology • How do we get the device?

  9. Debug and Triage Tips • Enabling debug spew • CHK drivers and matching symbols are required • ed ohci1394!ohcidebuglevel 2 • ed 1394bus!busdebuglevel 2 • Can use any level between 0 and 6 • Higher values result in more debug spew
