Merge tag 'vfio-v7.1-rc1' of https://github.com/awilliam/linux-vfioPull 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 ...

Fri, 13 Feb 2026 10:14:03 +0100

vfio/qat: extend Kconfig dependencies for 420xx and 6xxx devicesCurrently, the QAT VFIO PCI driver can only be configured when the 4xxxQAT driver (CRYPTO_DEV_QAT_4XXX) is enabled. This is too restrictive asthe VFIO driver also supports VFs from the 420xx and 6xxx devicefamilies, which share a compatible migration interface.Extends the Kconfig dependencies to allow configuration when any of thesupported QAT device families (4xxx, 420xx, or 6xxx) are enabled.Signed-off-by: Vijay Sundar Selvamani Signed-off-by: Suman Kumar Chakraborty Reviewed-by: Giovanni Cabiddu Link: https://lore.kernel.org/r/20260213091403.72338-1-suman.kumar.chakraborty@intel.comSigned-off-by: Alex Williamson List of files: /linux/drivers/vfio/pci/qat/Kconfig

vfio/qat: Add vfio_pci driver for Intel QAT SR-IOV VF devicesAdd vfio pci variant driver for Intel QAT SR-IOV VF devices. This driverregisters to the vfio subsystem through the interfaces exposed by thesubsystem. It follows the live migration protocol v2 defined inuapi/linux/vfio.h and interacts with Intel QAT PF driver through a setof interfaces defined in qat/qat_mig_dev.h to support live migration ofIntel QAT VF devices.This version only covers migration for Intel QAT GEN4 VF devices.Co-developed-by: Yahui Cao Signed-off-by: Yahui Cao Signed-off-by: Xin Zeng Reviewed-by: Giovanni Cabiddu Reviewed-by: Kevin Tian Link: https://lore.kernel.org/r/20240426064051.2859652-1-xin.zeng@intel.comSigned-off-by: Alex Williamson List of files: /linux/drivers/vfio/pci/qat/Kconfig
