R200 sample user mode driver
Posted by Prashant on December 19th, 2007


hii.. I have to write a WDDM user mode driver for virtual graphic adapter so
i am using user mode drivere code R200 sample that comes with WDK5600 as a
base. Without adding any functionality can I simply load it as user mode
drivere by masking all the unwanted function and just keeping the basic
function as mentioned in
http://msdn2.microsoft.com/en-us/library/ms797632.aspx .



thanx

Why? There is some sense in building an XPDM virtual driver, because you
can simulate the desktop. It's going to be EXTREMELY difficult to do the
same thing for WDDM. Remember that a WDDM device produces its desktop as a
composite of a series of textures. Do you expect to simulate a texture
engine?

WDK 5600 was a beta release. Job #1 for you is to get the released WDK,
build 6000.

Sure, if you have an ATI Radeon 8500 board. The user-mode driver doesn't
stand on its own.
