WDDM Bit Flip - Invalid Param First Group
This automated test checks the stability of invalid parameters. It verifies that kernel-mode video drivers correctly validate command buffers and private driver data that is passed from user mode.
The test runs in the layer between the user-mode video driver and the kernel-mode video driver. The test intercepts calls from user mode to kernel mode. It then modifies the data that is associated with these calls. Kernel-mode video drivers must be robust enough to handle invalid parameters that come from any user-mode module without crashing or hanging.
