Hello Zhenzhong,
Below are other gaps I can think of for now:Gaps: 1. dirty page sync, WIP (Joao) 2. p2p dma not supported yet. 3. fd passing with mdev not support ram discard(vfio-pci) as no way to know it'sa mdev from a fd. Call the section Caveats maybe?Got it.
It looks like v7 should be ready by rc2 (next week). I would then merge in vfio-next and wait a week before sending a QEMU-9.0 PR. Thanks, C.
