3D Acceleration for Windows hosts?

3D Acceleration for Windows hosts?

[John Klimek]

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).

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

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.

Thanks!

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.

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.

Thanks very much for the information.

However, when I try to run configure with --enable-opengl it reports
the following:

ERROR: User requested feature opengl
       configure was not able to find it.
       Please install opengl (mesa) devel pkgs: epoxy gbm

It looks like it requires gbm which is only available for Linux
DRM/KRS.  I don't see any configuration options to enable OpenGL with
SDL and GTK3?
