If page is unmapped then stage 2 (Host page table) gets updated. IOMMU will not be able to find page and logs fault.
As long as the fault is contained only for the relevant queue, yes we don't need another pinning from the driver.
Yeah, that's my expectation too. If the guest uses a bad address then the fault should be logged in HW and forwarded to the guest. No need to validate the guest IOVA for queues.
