title: Is User mode driver mandatory for WDDM 1.1 if test application use only WIN32 GDI calls?
body: <p>I am a newbie in Windows driver development. I am trying to learn to write a very basic dummy display driver in WDDM 1.1 driver architecture.</p>
  
  <p>My doubt is a very basic question: Is User mode driver mandatory for WDDM 1.1 architecture. I have seen an alternative path like: 
  Application -> Win32GDI -> Win32K.sys -> Dxgkrnl.sys -> Display Miniport driver (kernel mode driver) </p>
  
  <p>So can I make only the display miniport driver and install it; ignoring the user mode driver development and installation and make at least a very basic driver working? My test applications shall use ony WIN32 GDI APIs.</p>
  
  <p>One more query. where can I get a very basic sample of WDDM 1.1 driver? I have seen tutorials/dummy examples in codeproject for XPDM driver; but not for WDDM drivers. Please help..</p>
  
  <p>Thank you for your understanding and patience,</p>
  
  <p>Regards,</p>
