WDDM FlipQueue

  • Article

This automated test verifies that kernel-mode video drivers correctly implement flip queuing for hardware or software.

This test uses the GPU to render on many GPU device contexts simultaneously. One of the contexts does flipping operations. If the driver correctly implements flip queuing for hardware or software, the flipping operations that one context submits does not cause the GPU to stall and starve the other contexts. Drivers pass this test if the non-flipping contexts are not starved.
