Subject: [PATCH v1 00/20] iommu: Introduce and roll out test_dev domain op
Date: Sun, 12 Oct 2025 17:04:57 -0700 [thread overview]
Message-ID: <cover.1760312725.git.nicolinc@nvidia.com> (raw)
Add a new test_dev domain op for drivers to run a compatibility test prior
to the actual attachment at the driver level. Any incompatible attachment
will be rejected early, allowing the iommu core to postpone any concurrent
attachment during a device reset state.
This is a preparatory series for new iommu_dev_reset APIs:
https://lore.kernel.org/all/cover.1756682135.git.nicolinc@nvidia.com/
The change is a must to keep attach uAPI behavior consistent.
This is on github:
https://github.com/nicolinc/iommufd/tree/iommu_test_dev-v1
