Hi Linus, Below is the gvt pull request from Zhenyu, now that the vfio stuff has landed. I figured no point in passing this all through the various trees especially since Dave is kinda in vacation mode anyway. But I did a local test pull and looked all reasonable to me. Diffstat and summary is wrong ofc (includes the vfio stuff), for you it should just be the merge to create the baseline + 3 patches to add the gvt support. I can also regen and do a separate pull if you prefer this. In case Dave isn't around to ack, I discussed this a few weeks back with him and he said it should be ok. I hope that still holds.
