Pull VFIO updates from Alex Williamson: - Update QAT vfio-pci variant driver for Gen 5, 420xx devices (Vijay Sundar Selvamani, Suman Kumar Chakraborty, Giovanni Cabiddu) - Fix vfio selftest MMIO DMA mapping selftest (Alex Mastro) - Conversions to const struct class in support of class_create() deprecation (Jori Koolstra) - Improve selftest compiler compatibility by avoiding initializer on variable-length array (Manish Honap) - Define new uAPI for drivers supporting migration to advise user- space of new initial data for reducing target startup latency. Implemented for mlx5 vfio-pci variant driver (Yishai Hadas) - Enable vfio selftests on aarch64, not just cross-compiles reporting arm64 (Ted Logan) - Update vfio selftest driver support to include additional DSA devices (Yi Lai) - Unconditionally include debugfs root pointer in vfio device struct, avoiding a build failure seen in hisi_acc variant driver without debugfs otherwise (Arnd Bergmann) - Add support for the s390 ISM (Internal Shared Memory) device via a new variant driver. The device is unique in the size of its BAR space (256TiB) and lack of mmap support (Julian Ruess) - Enforce that vfio-pci drivers implement a name in their ops structure for use in sequestering SR-IOV VFs (Alex Williamson) - Prune leftover group notifier code (Paolo Bonzini) - Fix Xe vfio-pci variant driver to avoid migration support as a dependency in the reset path and missing release call (Michał Winiarski) * tag 'vfio-v7.1-rc1' of https://github.com/awilliam/linux-vfio: (23 commits) vfio/xe: Add a missing vfio_pci_core_release_dev() vfio/xe: Reorganize the init to decouple migration from reset vfio: remove dead notifier code vfio/pci: Require vfio_device_ops.name MAINTAINERS: add VFIO ISM PCI DRIVER section vfio/ism: Implement vfio_pci driver for ISM devices vfio/pci: Rename vfio_config_do_rw() to vfio_pci_config_rw_single() and export it vfio: unhide vdev->debug_root vfio/qat: add support for Intel QAT 420xx VFs vfio: selftests: Support DMR and GNR-D DSA devices vfio: selftests: Build tests on aarch64 vfio/mlx5: Add REINIT support to VFIO_MIG_GET_PRECOPY_INFO vfio/mlx5: consider inflight SAVE during PRE_COPY net/mlx5: Add IFC bits for migration state vfio: Adapt drivers to use the core helper vfio_check_precopy_ioctl vfio: Add support for VFIO_DEVICE_FEATURE_MIG_PRECOPY_INFOv2 vfio: Define uAPI for re-init initial bytes during the PRE_COPY phase vfio: selftests: Fix VLA initialisation in vfio_pci_irq_set() vfio: uapi: fix comment typo vfio: mdev: replace mtty_dev->vd_class with a const struct class ...

net/mlx5: Add icm_mng_function_id_mode cap bit

2026-04-09T09:26:39+00:00

Introduce the capability bit icm_mng_function_id_mode to indicate that the device firmware uses vhca_id instead of function_id as the effective identifier for the firmware commands MANAGE_PAGES, QUERY_PAGES, and page request event.

net/mlx5: Rename MLX5_PF page counter type to MLX5_SELF

2026-04-09T09:26:39+00:00

The MLX5_PF enum value in mlx5_func_type is used to track firmware page allocations for the page manager function itself, which is either the ECPF on SmartNIC systems or the host PF when there is no ECPF. Rename it to MLX5_SELF to accurately reflect that this counter tracks pages allocated by the manager for its own use, regardless of whether it is a PF or ECPF.

net/mlx5: Add vhca_id_type bit to alias context

2026-03-22T18:40:36+00:00

Add vhca_id_type bit to alias context which allows indicating the vhca_id_type to be passed at vhca_id_to_be_accessed, which can be either HW or SW, note that SW_VHCA_ID must be used to allow alias to work properly after migration.

mlx5: Remove redundant iseg base

2026-03-22T18:40:36+00:00

iseg_base and base_addr both point to BAR0, making iseg_base redundant. Remove iseg_base and rely on base_addr instead, reducing the size of struct mlx5_core_dev.

{net/RDMA}/mlx5: Add LAG demux table API and vport demux rules

2026-03-16T20:23:00+00:00

Downstream patches will introduce SW-only LAG (e.g. shared_fdb without HW LAG). In this mode the firmware cannot create the LAG demux table, but vport demuxing is still required. Move LAG demux flow-table ownership to the LAG layer and introduce APIs to init/cleanup the demux table and add/delete per-vport rules. Adjust the RDMA driver to use the new APIs. In this mode, the LAG layer will create a flow group that matches vport metadata. Vports that are not native to the LAG master eswitch add the demux rule during IB representor load and remove it on unload. The demux rule forward traffic from said vports to their native eswitch manager via a new dest type - MLX5_FLOW_DESTINATION_TYPE_VHCA_RX.
