WDDM Dead Lock

  • Article

This automated test verifies that user-mode and kernel-mode drivers correctly synchronize calls from multiple processes and threads.

This test calls into the user-mode and kernel-mode video drivers concurrently from multiple processes and threads. Video drivers must correctly synchronize access to shared data structures to make sure that the system is stable in this scenario. Drivers pass this test if they do not cause the system to crash or hang while the test is running.
