Hi Dave, Simona! Here's a PR of the xe-vfio driver variant for xe as discussed on IRC. It includes some prereq drm-xe patches and the vfio driver itself. For ack to merge through drm, please see second Link: in the vfio driver patch.
Using a topic branch as suggested. Thanks, Thomas topic/xe-vfio-2025-12-01: Cross-subsystem Changes: - Add device specific vfio_pci driver variant for intel graphics (Michal Winiarski) Driver Changes: - Add scope-based cleanup helper for runtime PM (Matt Roper) - Additional xe driver prerequisites and exports (Michal Winiarski) The following changes since commit 62433efe0b06042d8016ba0713d801165a939229: Merge tag 'drm-misc-next-fixes-2025-11-26' of https://gitlab.freedesktop.org/drm/misc/kernel into drm-next (2025-11-28 09:04:52 +1000) are available in the Git repository at: https://gitlab.freedesktop.org/drm/xe/kernel.git tags/topic/xe-vfio-2025-12-01 for you to fetch changes up to 1f5556ec8b9efbb784aeb3536e147182dee73d0f: vfio/xe: Add device specific vfio_pci driver variant for Intel graphics (2025-12-01 09:45:48 +0100) ---------------------------------------------------------------- Cross-subsystem Changes: - Add device specific vfio_pci driver variant for intel graphics (Michal Winiarski) Driver Changes: - Add scope-based cleanup helper for runtime PM (Matt Roper) - Additional xe driver prerequisites and exports (Michal Winiarski) ---------------------------------------------------------------- Matt Roper (1): drm/xe/pm: Add scope-based cleanup helper for runtime PM Michał Winiarski (4): drm/xe/pf: Enable SR-IOV VF migration drm/xe/pci: Introduce a helper to allow VF access to PF xe_device drm/xe/pf: Export helpers for VFIO vfio/xe: Add device specific vfio_pci driver variant for Intel graphics MAINTAINERS | 7 + drivers/gpu/drm/xe/Makefile | 4 + drivers/gpu/drm/xe/xe_gt_sriov_pf_migration.c | 9 + drivers/gpu/drm/xe/xe_pci.c | 17 + drivers/gpu/drm/xe/xe_pci.h | 3 + drivers/gpu/drm/xe/xe_pm.c | 21 + drivers/gpu/drm/xe/xe_pm.h | 17 + drivers/gpu/drm/xe/xe_sriov_pf_migration.c | 35 +- drivers/gpu/drm/xe/xe_sriov_pf_migration.h | 1 + drivers/gpu/drm/xe/xe_sriov_pf_migration_types.h | 4 +- drivers/gpu/drm/xe/xe_sriov_vfio.c | 80 ++++ drivers/vfio/pci/Kconfig | 2 + drivers/vfio/pci/Makefile | 2 + drivers/vfio/pci/xe/Kconfig | 12 + drivers/vfio/pci/xe/Makefile | 3 + drivers/vfio/pci/xe/main.c | 573 +++++++++++++++++++++++ include/drm/intel/xe_sriov_vfio.h | 143 ++++++ 17 files changed, 926 insertions(+), 7 deletions(-) create mode 100644 drivers/gpu/drm/xe/xe_sriov_vfio.c create mode 100644 drivers/vfio/pci/xe/Kconfig create mode 100644 drivers/vfio/pci/xe/Makefile create mode 100644 drivers/vfio/pci/xe/main.c create mode 100644 include/drm/intel/xe_sriov_vfio.h
