Hi Alex,
this series cleans up how iommu group are created in VFIO as well as
various other lose ends around that. It sits on top of the
"Introduce vfio_pci_core subsystem"
series from Yishai
Changes since v3:
- restore the attribution to Jason for patch 1, which git-rebase lost
- fix a vfio vs iommu group counting issue that I added over Jasons
original patch
- add comments describing the VFIO_EMULATED_IOMMU and VFIO_NO_IOMMU
flags
- use the emulated iommu naming consistently in comments
- a spelling fix
Changes since v2:
- cosmetic changes to the code flow in vfio_group_find_or_alloc
- replace "mediated" with "emulated iommu"
- add a comment describing vfio_register_emulated_iommu_dev
- rebased on top of the "Introduce vfio_pci_core subsystem" series
Changes since v1:
- only taint if a noiommu group was successfully created
