As I mentioned in the previous mail, we already have a blog article, which can be easily found by googling xengt: :-) https://01.org/xen/blogs/srclarkx/2013/graphics-virtualization-xengt >>> Also: Haswell ("4th generation Intel core CPU") is listed as a >>> requirement in the Setup Guide PDF.. will there be support for SNB/IVB >>> GPUs aswell? >> There is no plan for SNB/IVB. >> > > Is that because of some hardware limitation on earlier GPU generations, > or just a matter of amount of work needed to support XenGT on earlier > GPUs? > -- Pasi No HW limitation on earlier GPUs -- actually you can even see some unused codes about earlier generations in the linux-vgt.patch. At present we'd like to focus on HSW (and newer generation in future). -- Dexuan -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
