Thanks, Alex The following changes since commit a5806cd506af5a7c19bcd596e4708b5c464bfd21: Linux 6.15-rc7 (2025-05-18 13:57:29 -0700) are available in the Git repository at: https://github.com/awilliam/linux-vfio.git tags/vfio-v6.16-rc1 for you to fetch changes up to 4518e5a60c7fbf0cdff393c2681db39d77b4f87e: vfio/type1: Fix error unwind in migration dirty bitmap allocation (2025-05-22 10:41:24 -0600) ---------------------------------------------------------------- VFIO updates for v6.16-rc1 - Remove an outdated DMA unmap optimization that relies on a feature only implemented in AMDv1 page tables. (Jason Gunthorpe) - Fix various migration issues in the hisi_acc_vfio_pci variant driver, including use of a wrong DMA address requiring an update to the migration data structure, resending task completion interrupt after migration to re-sync queues, fixing a write-back cache sequencing issue, fixing a driver unload issue, behaving correctly when the guest driver is not loaded, and avoiding to squash errors from sub-functions. (Longfang Liu) - mlx5-vfio-pci variant driver update to make use of the new two-step DMA API for migration, using a page array directly rather than using a page list mapped across a scatter list. (Leon Romanovsky) - Fix an incorrect loop index used when unwinding allocation of dirty page bitmaps on error, resulting in temporary failure in freeing unused bitmaps. (Li RongQing) ---------------------------------------------------------------- Alex Williamson (1): Merge branch 'dma-mapping-for-6.16-two-step-api' of git://git.kernel.org/pub/scm/linux/kernel/git/mszyprowski/linux into v6.16/vfio/next Jason Gunthorpe (1): vfio/type1: Remove Fine Grained Superpages detection Leon Romanovsky (3): vfio/mlx5: Explicitly use number of pages instead of allocated length vfio/mlx5: Rewrite create mkey flow to allow better code reuse vfio/mlx5: Enable the DMA link API Li RongQing (1): vfio/type1: Fix error unwind in migration dirty bitmap allocation Longfang Liu (6): hisi_acc_vfio_pci: fix XQE dma address error hisi_acc_vfio_pci: add eq and aeq interruption restore hisi_acc_vfio_pci: bugfix cache write-back issue hisi_acc_vfio_pci: bugfix the problem of uninstalling driver hisi_acc_vfio_pci: bugfix live migration function without VF device driver hisi_acc_vfio_pci: update function return values. drivers/vfio/pci/hisilicon/hisi_acc_vfio_pci.c | 121 +++----- drivers/vfio/pci/hisilicon/hisi_acc_vfio_pci.h | 14 +- drivers/vfio/pci/mlx5/cmd.c | 371 +++++++++++++------------ drivers/vfio/pci/mlx5/cmd.h | 35 +-- drivers/vfio/pci/mlx5/main.c | 87 +++--- drivers/vfio/vfio_iommu_type1.c | 51 +++- 6 files changed, 341 insertions(+), 338 deletions(-)
