--- Comment #25 from Marietto <marietto2008 at gmail dot com> ---
Hello.

I'm trying to configure and compile GVT-g to enable the passthrough of the
integrated GPU that I have on my motherboard,the model "Intel Corporation UHD
Graphics 630 (Desktop 9 Series) (rev 02)". This is the tutorial that I'm
following :

https://lists.freedesktop.org/archives/intel-gvt-dev/2017-June/001238.html

I reached this point and then the compilation stopped for an error that it
seems to be the same as this.

I don't understand where is the patch ?
