Merge tag 'vfio-v6.19-rc1' of https://github.com/awilliam/linux-vfioPull VFIO updates from Alex Williamson: - Move libvfio selftest artifacts in preparation of more tightly coupled integration with KVM selftests (David Matlack) - Fix comment typo in mtty driver (Chu Guangqing) - Support for new hardware revision in the hisi_acc vfio-pci variant driver where the migration registers can now be accessed via the PF. When enabled for this support, the full BAR can be exposed to the user (Longfang Liu) - Fix vfio cdev support for VF token passing, using the correct size for the kernel structure, thereby actually allowing userspace to provide a non-zero UUID token. Also set the match token callback for the hisi_acc, fixing VF token support for this this vfio-pci variant driver (Raghavendra Rao Ananta) - Introduce internal callbacks on vfio devices to simplify and consolidate duplicate code for generating VFIO_DEVICE_GET_REGION_INFO data, removing various ioctl intercepts with a more structured solution (Jason Gunthorpe) - Introduce dma-buf support for vfio-pci devices, allowing MMIO regions to be exposed through dma-buf objects with lifecycle managed through move operations. This enables low-level interactions such as a vfio-pci based SPDK drivers interacting directly with dma-buf capable RDMA devices to enable peer-to-peer operations. IOMMUFD is also now able to build upon this support to fill a long standing feature gap versus the legacy vfio type1 IOMMU backend with an implementation of P2P support for VM use cases that better manages the lifecycle of the P2P mapping (Leon Romanovsky, Jason Gunthorpe, Vivek Kasireddy) - Convert eventfd triggering for error and request signals to use RCU mechanisms in order to avoid a 3-way lockdep reported deadlock issue (Alex Williamson) - Fix a 32-bit overflow introduced via dma-buf support manifesting with large DMA buffers (Alex Mastro) - Convert nvgrace-gpu vfio-pci variant driver to insert mappings on fault rather than at mmap time. This conversion serves both to make use of huge PFNMAPs but also to both avoid corrected RAS events during reset by now being subject to vfio-pci-core's use of unmap_mapping_range(), and to enable a device readiness test after reset (Ankit Agrawal) - Refactoring of vfio selftests to support multi-device tests and split code to provide better separation between IOMMU and device objects.

Thu, 27 Nov 2025 00:17:17 +0100

vfio: selftests: Split run.sh into separate scriptsSplit run.sh into separate scripts (setup.sh, run.sh, cleanup.sh) toenable multi-device testing, and prepare for VFIO selftestsautomatically detecting which devices to use for testing by storingdevice metadata on the filesystem. - setup.sh takes one or more BDFs as arguments and sets up each device. Metadata about each device is stored on the filesystem in the directory: ${TMPDIR:-/tmp}/vfio-selftests-devices Within this directory is a directory for each BDF, and then files in those directories that cleanup.sh uses to cleanup the device. - run.sh runs a selftest by passing it the BDFs of all set up devices. - cleanup.sh takes zero or more BDFs as arguments and cleans up each device. If no BDFs are provided, it cleans up all devices.This split enables multi-device testing by allowing multiple BDFs to beset up and passed into tests:For example: $ tools/testing/selftests/vfio/scripts/setup.sh $ tools/testing/selftests/vfio/scripts/setup.sh $ tools/testing/selftests/vfio/scripts/run.sh echo $ tools/testing/selftests/vfio/scripts/cleanup.shIn the future, VFIO selftests can automatically detect set up devices byinspecting ${TMPDIR:-/tmp}/vfio-selftests-devices. This will avoid theneed for the run.sh script.Reviewed-by: Alex Mastro Tested-by: Alex Mastro Reviewed-by: Raghavendra Rao Ananta Signed-off-by: David Matlack Link: https://lore.kernel.org/r/20251126231733.3302983-3-dmatlack@google.comSigned-off-by: Alex Williamson List of files: /linux/tools/testing/selftests/vfio/Makefile
