Hi Linus, The following changes since commit d7b8f8e20813f0179d8ef519541a3527e7661d3a: Linux 6.16-rc5 (2025-07-06 14:10:26 -0700) are available in the Git repository at: https://github.com/awilliam/linux-vfio.git tags/vfio-v6.17-rc1 for you to fetch changes up to d2272d898186fa96c6fa4ad067219b45b8c2ef5f: vfio/type1: correct logic of vfio_find_vpfn() (2025-07-27 08:20:31 -0600) ---------------------------------------------------------------- VFIO updates for v6.17-rc1 - Fix imbalance where the no-iommu/cdev device path skips too much on open, failing to increment a reference, but still decrements the reference on close. Add bounds checking to prevent such underflows. (Jacob Pan) - Fill missing detach_ioas op for pds_vfio_pci, fixing probe failure when used with IOMMUFD. (Brett Creeley) - Split SR-IOV VFs to separate dev_set, avoiding unnecessary serialization between VFs that appear on the same bus. (Alex Williamson) - Fix a theoretical integer overflow is the mlx5-vfio-pci variant driver. (Artem Sadovnikov) - Use batching on contiguous pages to significantly improve DMA map and unmap performance when using hugetlbfs or THP backed memory with the legacy vfio type1 IOMMU backend. (Li Zhe) - Implement missing VF token checking support via vfio cdev/IOMMUFD interface. (Jason Gunthorpe) - Update QAT vfio-pci variant driver to claim latest VF devices. (Małgorzata Mielnik) - Add a cond_resched() call to avoid holding the CPU too long during DMA mapping operations.
