I do have verified build and tested it on x86_64 platform. > Have you verified x86 and PPC/ARM build (which I think primarily could > use VFIO)? I have not, but I'm fairly confident that CONFIG_SAMPLES is not a typical user or distro config option, so I think we're at a low risk of breaking anyone. In general I test almost exclusively for x86_64 and rely on external auto builders to identify issues on other archs.
