Note that Venus now requires VIRGL_RENDERER_RENDER_SERVER flag to be
set. Please test the patches with the latest virglrenderer and etc.

The #ifdef also doesn't allow adding new flags, it should look like:

#ifdef VIRGL_RENDERER_VENUS
    flags |= VIRGL_RENDERER_RENDER_SERVER;
#endif

    ret = virgl_renderer_init(g, flags, &virtio_gpu_3d_cbs);

In fact, we have rebased to the latest virglrenderer:

We check both VIRGL_RENDERER_RENDER_SERVER or VIRGL_RENDERER_VENUS in
virglrenderer, alternative of them works.

All the extra changes you made to virglrenderer that Qemu depends on
need to go upstream. Please open all the relevant merge requests. Thanks!

Dmitry, sorry to late response, I have created relevant merge requests
below:

Virglrenderer:

BTW, Alex reviewed the Venus v3 patches a month ago [1] and the review
comments need to be addressed. AFAICS, you're actually using the very
old Venus patches here that stopped working about a year ago, so again
you're using a very outdated virglrenderer version.

Please take it all into account if you'll beat me to posting the next
version of Venus patches ;)

Thanks Dmitry point it out, I will use the latest v3 patches, and try to
address the comments in next version. :-)
