Building a Universal Windows Driver

Intel® oneAPI Math Kernel Library
 is compatible with Universal Windows Drivers (UWDs) whose binaries are Win10 SDK version 1803 (also called Redstone 4, RS4 or Win 10 SDK build 10.0.17134.0) or higher. The Windows system calls used in the statically linked libraries are defined in:
  • OneCore.Lib
     for headless applications like Nano Server.
  • OneCoreUAP.Lib
     for a UWD.
A Windows application or driver that links to either of these libraries can use functionality from statically linked
Intel® oneAPI Math Kernel Library
 to accelerate computations. For more information on design criteria for a UWD, see the Microsoft website.
This table summarizes important information about compatibility between
Intel® oneAPI Math Kernel Library
 and UWDs.

Architecture
  • ia32

Universal API sets
  • OneCore.Lib

  • OneCoreUAP.Lib
     for a UWD
Threading layers
  • Sequential
  • Intel® Threading Building Blocks (Intel® TBB).
UWD Compliance
  • Intel® oneAPI Math Kernel Library
     with static linking libraries
  • For dynamic linking libraries, use the custom DLL builder with
    uwd_compat
    =
    yes
     to construct a custom DLL that is compatible with UWD. See Using the Custom DLL Builder.
The UWD links to
Intel® oneAPI Math Kernel Library
 using the same link line settings as drivers or executables that are not universal. See Link Line Advisor for recommended linking models.
