Windows Performance Analyzer: not found KMDF section in computation part

I wanna use WPA to analyze behavior of drivers and I followed the two tutorial to set my computer.

  1. Using KMDF Verifier

  2. Using the Windows Performance Toolkit (WPT) with WDF

The following is what I have done step by step, but it doesn't work.

  1. I set VerifierOn to 0x1 at first and set EnhancedVerifierOptions to 0xf00000.

  2. Then, reboot the computer.

  3. Launch Windows Performance Recorder and select the column of WDF Drivers. Then, save the result into an ETL file.

  4. Finally, use Windows Performance Analyzer to browse the result.

I couldn't find the KMDF section in compute section.
