Intel XenGT has another maillist " igv...@lists.01.org" to discuss Intel GPU virtualization questions, including XenGT and KVMGT. Feel free to subscribe.
Right now, we have two version GVT-g, "old architecture" vs "new architecture for upstream" Old architecture: - The codes are maintained off-tree, support both XenGT and KVMGT. - Our latest code is 2016Q3 version in Oct'16, 2016Q4 version is coming soon due to some open bugs. - 2016Q3 release blog: https://01.org/igvt-g/blogs/wangbo85/2016/intel-gvt-g-iso-public-release-q32016 - Repo Kernel: https://github.com/01org/igvtg-kernel Xen: https://github.com/01org/igvtg-xen QEMU: https://github.com/01org/igvtg-qemu New architecture for upstream: - KVMGT version with new VFIO interface have been upstreamed into kernel 4.10. You can see the code from kernel 4.10, or from our own GVT-g repo which hosts latest code and bug fixing. - Repo Kernel: https://github.com/01org/gvt-linux.git QEMU: git://git.qemu.org/qemu.git - XenGT code upstream is ongoing, not upstreamed. So you can't see those code yet. We already have a workable XenGT version for upstream, may share the code after interface polishing. More details about two versions, please refer to below introduction blog: https://01.org/igvt-g/blogs/wangbo85/2017/gvt-g-upstream-status-update-were-transition-phase Best regards.
