Hi Jike, Thanks for summarizing this, but I will defer to Kirti to comment on the actual upstream status of her patches, couples things to note though: 1) iommu type1 patches have been extensively reviewed by Alex already and we have one action item left to implement which is already queued up in v8 patchset. 2) regarding the sysfs interface and libvirt discussion, I would like to hear what kind of attributes Intel folks are having so far as Daniel is asking about adding a class "gpu" which will pull several attributes as mandatory.
