Or perhaps calling them "non-accelerated commands" would be nicer.
Uhh okay, so there'll be a separate driver in the VM issuing invalidation commands directly to the CMDQV thus we don't see any of it's part here?
That's how it works. VM must run a guest-level VCMDQ driver that separates accelerated and non-accelerated commands as it already does:
accelerated commands => VCMDQ (HW) non-accelerated commands => SMMU CMDQ (SW) =iommufd=> SMMU CMDQ (HW)
