Wireless Display Verify OPM On Real Sink

This manual test verifies that the graphics driver lists support for H264 protection and that it can be enabled on the Miracast display. The test requires a Miracast connection that is established on real hardware that has H264 support. For example, connect a sink to a monitor over a HDMI cable.

Additional documentation

Tests in this feature area might have additional documentation, including prerequisites, setup, and troubleshooting information, that can be found in the following topic(s):

Running the test

Before you run the test, complete the test setup as described in the test requirements: Graphic Adapter or Chipset Testing Prerequisites.

Troubleshooting

For generic troubleshooting of HLK test failures, see Troubleshooting Windows HLK Test Failures.

For troubleshooting information, see Troubleshooting Device.Graphics Testing.

The test generates an RTSP message log file: virtualsinklog.{…}.txt. The actual name of this file can be found in the test log file. For example:

Message 6/13/2013 7:39:22.724 PM RTSP log file: virtualsinklog.{3D55759A-4BB2-43C6-9AD6-9D98D6726908}.txt

The test job captures WirelessDisplay.etl and WPP.etl files. You can find these files by selecting Child Job Results in Windows Hardware Lab Kit (Windows HLK) Manager and then browsing job logs for Wireless Display Cleanup Trace.

WirelessDisplay.etl contains information about the Miracast session from start to stop. Most events are aligned with DDI calls for both the user mode driver (UMD) and kernel mode driver (KMD).  IHV investigating issues might find it useful to look for errors in these DDI events.  The event names should be familiar to the developer because they closely match the DDI names that are used for the wireless feature.  This file can be analyzed by using Windows Performance Analyzer (WPA).

WPP.etl contains WPP traces that are captured for the display kernel events related to Miracast. These traces are highly detailed, and should provide adequate information about session failures that is sufficient to debug most issues. These files require access to symbols to decode them. Symbols for the OS should be available to IHVs. The following command line should be used to decode WPP.etl in wpp.txt is: netsh trace convert overwrite=yes tmf=..\symbols.pri\TraceFormat WPP.etl.

All test cases return PASS or FAIL. The test details are available in the test log (Te.wtl), which you can view in Windows HLK Studio.

Error Description/Workaround

Failed: Wireless monitor is not connected.

The hardware was not properly set up.

Failed: HDCP can't be set, but reported as supported.

Driver failed to establish the high-bandwidth digital content protection (HDCP) connection.

Pass: HDCP is not supported on wireless output. HDCP support is optional.

Driver or connection doesn't support HDCP.

If the driver is supposed to support HDCP, rerun the test by attaching an appropriate wireless display.
