This CL adds a new D3D11on12 device option which runs the D3D11 API on top of D3D12. This is done to aid in preliminary investigations into the feasibility of creating a full D3D12 backend implementation.

New Behavior
|
|
|
|
To request a D3D11on12 display the value of
|
|
EGL_PLATFORM_ANGLE_D3D11ON12_ANGLE should be set to EGL_TRUE.
|
|
|
|
If EGL_PLATFORM_ANGLE_D3D11ON12_ANGLE is included in the
|
|
<attrib_list> argument of eglGetPlatformDisplayEXT and
|
|
EGL_PLATFORM_ANGLE_TYPE_ANGLE is not set to
|
|
EGL_PLATFORM_ANGLE_TYPE_D3D11_ANGLE, an EGL_BAD_ATTRIBUTE error is
|
|
generated and EGL_NO_DISPLAY is returned.
|
|
|
|
EGL_PLATFORM_ANGLE_D3D11ON12_ANGLE can be combined with
|
|
EGL_PLATFORM_ANGLE_DEVICE_TYPE_ANGLE if it is set to
|
|
EGL_PLATFORM_ANGLE_DEVICE_TYPE_HARDWARE_ANGLE or
|
|
EGL_PLATFORM_ANGLE_DEVICE_TYPE_D3D_WARP_ANGLE. Other device types
|
|
will generate an EGL_BAD_ATTRIBUTE error and return
|
|
EGL_NO_DISPLAY.
