Subject: [PATCH 0/2] Remove iommu_group_remove_device() from fsl
Date: Mon, 15 May 2023 21:27:07 -0300 [thread overview]
Message-ID: <0-v1-8fb05192ea02+e5-fsl_rm_groups_jgg@nvidia.com> (raw)
With POWER SPAPR now having a real iommu driver and using the normal group
lifecycle stuff fixing FSL will leave only VFIO's no-iommu support as a
user for the iommu_group_add/remove_device() calls. This will help
simplify the understanding of what the core code should be doing for these
functions.
Fix FSL to not need to call iommu_group_remove_device() at all.
Jason Gunthorpe (2):
iommu/fsl: Do not use iommu_group_remove_device() under
ops->device_group()
iommu/fsl: Always allocate a group for non-pci devices
