Add a new IOMMUFD_OBJ_VCMDQ with an iommufd_vcmdq structure, representing a command queue type of physical HW passed to or shared with a user space VM.
what is the implication of "or shared with"? Do you intend to support an usage in which a CMDQ is coordinated by both guest and host (which sounds insane)?
No. It should have been removed. Was for "vQUEUE" previously for a potential wider use case. Will fix this.
Thanks Nicolin
