Does QEMU have any support for 3D acceleration on Windows hosts?

I'm not too familiar with video/graphics libraries, but it seems like
QEMU OpenGL support requires Mesa GBM which is only available for
Linux (DRM/KMS).

In theory, the SDL and GTK3 backends should work on Windows with gl=on. But I don't think anyone really tried it, so a few fixes are to be expected.


The other option is the Virgl3D renderer but that also requires Linux (DRM).


Not so long ago, it was possible to cross-compile virgl for windows. But virgl depends on a functioning QEMU GL backend, so getting the above is a preliminary. Note that OpenGL drivers on Windows have been notoriously bad, and you may need to use ANGLE.
 
I'm not really sure if I know what I'm talking about so please correct
me if I'm wrong and also let me know if there is a way to enable 3D
acceleration under Windows hosts.
