    Hi All,

    I'm working on r200umd user-mode sample display driver and I'm facing some
    problem after its Openadapter function is getting called.
    Openadapter is returning status as S_OK. In this call, it is passing
    pointers of
    CreateDevice and GetCaps.

    After this call, GetCaps is getting called but in the WDDM documentation
    nothing much is mentioned about this function. And inside this function,
    sometimes I'm getting BSOD after calling 'bDD4DISPInitDD' function inside
    R200D3DDevInit function. And sometimes GetCaps is getting called repetitively
    and after some iterations getting crash.

    But never got a call for CreateDevice. Actually I would like to know what
    GetCaps should return and when CreateDevice will get called and why GetCaps
    is getting called repetitively??

    Thanks & Regards,
    Anuj Agarwal
