Subject: [PATCH v2 0/6] iommu: Pass in old_domain pointer to attach_dev
Date: Wed, 22 Oct 2025 19:21:03 -0700 [thread overview]
Message-ID: <cover.1761017765.git.nicolinc@nvidia.com> (raw)
Tidy the release_device callbacks in the drivers and switch to the core
managed release_domain.
This allows the core further to pass in the old domain pointer into the
attach_dev callbacks to reduce the use of iommu_get_domain_for_dev().
This is a preparatory series for new iommu_dev_reset APIs:
https://lore.kernel.org/all/cover.1756682135.git.nicolinc@nvidia.com/
This is on github:
https://github.com/nicolinc/iommufd/tree/iommu_attach_old_dom-v2
