Subject: cleanup vfio iommu_group creation v5
Date: Mon, 13 Sep 2021 09:15:52 +0200 [thread overview]
Message-ID: <20210913071606.2966-1-hch@lst.de> (raw)
Hi Alex,
this series cleans up how iommu group are created in VFIO as well as
various other lose ends around that.
Terrence: I did not pick up your Tested-by as there were quite a few
changes and a major rebase.
Changes since v4:
- clean up an intermediate version of vfio_group_find_or_alloc to avoid
reviewer confusion
- replace an incorrect NULL check with IS_ERR
- rebased ontop of the vfio_ap_ops changes in Linux 5.15-rc
- improve a commit message
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
