bf4197be96d0839963d28e1812d9edc71086a580 - vfio/ism: Implement vfio_pci driver for ISM devices

Wed, 25 Mar 2026 14:31:24 +0100

vfio/ism: Implement vfio_pci driver for ISM devicesAdd a vfio_pci variant driver for the s390-specific Internal SharedMemory (ISM) devices used for inter-VM communication.This enables the development of vfio-pci-based user space drivers forISM devices.On s390, kernel primitives such as ioread() and iowrite() are switchedover from function-handle-based PCI load/stores instructions to PCImemory-I/O (MIO) loads/stores when these are available and notexplicitly disabled. Since these instructions cannot be used with ISMdevices, ensure that classic function-handle-based PCI instructions areused instead.The driver is still required even when MIO instructions are disabled, asthe ISM device relies on the PCI store block (PCISTB) instruction toperform write operations.Stores are not fragmented, therefore one ioctl corresponds to exactlyone PCISTB instruction. User space must ensure to not write more than4096 bytes at once to an ISM BAR which is the maximum payload of thePCISTB instruction.Reviewed-by: Alexandra Winter Reviewed-by: Niklas Schnelle Signed-off-by: Julian Ruess Reviewed-by: Farhan Ali Link: https://lore.kernel.org/r/20260325-vfio_pci_ism-v8-2-ddc504cde914@linux.ibm.comSigned-off-by: Alex Williamson List of files: /linux/drivers/vfio/pci/Makefile

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.

Tue, 25 Nov 2025 17:46:52 +0100

Merge branch 'iommufd_dmabuf' into k.o-iommufd/for-nextJason Gunthorpe says:====================This series is the start of adding full DMABUF support toiommufd. Currently it is limited to only work with VFIO's DMABUF exporter.It sits on top of Leon's series to add a DMABUF exporter to VFIO: https://lore.kernel.org/all/20251120-dmabuf-vfio-v9-0-d7f71607f371@nvidia.com/The existing IOMMU_IOAS_MAP_FILE is enhanced to detect DMABUF fd's, butotherwise works the same as it does today for a memfd. The user can selecta slice of the FD to map into the ioas and if the underliyng alignmentrequirements are met it will be placed in the iommu_domain.Though limited, it is enough to allow a VMM like QEMU to connect MMIO BARmemory from VFIO to an iommu_domain controlled by iommufd. This is usedfor PCI Peer to Peer support in VMs, and is the last feature that the VFIOtype 1 container has that iommufd couldn't do.The VFIO type1 version extracts raw PFNs from VMAs, which has no lifetimecontrol and is a use-after-free security problem.Instead iommufd relies on revokable DMABUFs. Whenever VFIO thinks thereshould be no access to the MMIO it can shoot down the mapping in iommufdwhich will unmap it from the iommu_domain. There is no automatic remap,this is a safety protocol so the kernel doesn't get stuck. Userspace isexpected to know it is doing something that will revoke the dmabuf andmap/unmap it around the activity. Eg when QEMU goes to issue FLR it shoulddo the map/unmap to iommufd.Since DMABUF is missing some key general features for this use case itrelies on a "private interconnect" between VFIO and iommufd via thevfio_pci_dma_buf_iommufd_map() call.The call confirms the DMABUF has revoke semantics and delivers a phys_addrfor the memory suitable for use with iommu_map().Medium term there is a desire to expand the supported DMABUFs to includeGPU drivers to support DPDK/SPDK type use cases so future series will workto add a general concept of revoke and a general negotiation ofinterconnect to remove vfio_pci_dma_buf_iommufd_map().I also plan another series to modify iommufd's vfio_compat totransparently pull a dmabuf out of a VFIO VMA to emulate more of the uAPIof type1.The latest series for interconnect negotation to exchange a phys_addr is: https://lore.kernel.org/r/20251027044712.1676175-1-vivek.kasireddy@intel.comAnd the discussion for design of revoke is here: https://lore.kernel.org/dri-devel/20250114173103.GE5556@nvidia.com/====================Based on a shared branch with vfio.* iommufd_dmabuf: iommufd/selftest: Add some tests for the dmabuf flow iommufd: Accept a DMABUF through IOMMU_IOAS_MAP_FILE iommufd: Have iopt_map_file_pages convert the fd to a file iommufd: Have pfn_reader process DMABUF iopt_pages iommufd: Allow MMIO pages in a batch iommufd: Allow a DMABUF to be revoked iommufd: Do not map/unmap revoked DMABUFs iommufd: Add DMABUF to iopt_pages vfio/pci: Add vfio_pci_dma_buf_iommufd_map() vfio/nvgrace: Support get_dmabuf_phys vfio/pci: Add dma-buf export support for MMIO regions vfio/pci: Enable peer-to-peer DMA transactions by default vfio/pci: Share the core device pointer while invoking feature functions vfio: Export vfio device get and put registration helpers dma-buf: provide phys_vec to scatter-gather mapping routine PCI/P2PDMA: Document DMABUF model PCI/P2PDMA: Provide an access to pci_p2pdma_map_type() function PCI/P2PDMA: Refactor to separate core P2P functionality from memory allocation PCI/P2PDMA: Simplify bus address mapping API PCI/P2PDMA: Separate the mmap() support from the core logicSigned-off-by: Jason Gunthorpe List of files: /linux/drivers/vfio/pci/Makefile
