Hi Linus, The following changes since commit 33cc938e65a98f1d29d0a18403dbbee050dcad9a: Linux 6.7-rc4 (2023-12-03 18:52:56 +0900) are available in the Git repository at: https://github.com/awilliam/linux-vfio.git tags/vfio-v6.8-rc1 for you to fetch changes up to 78f70c02bdbccb5e9b0b0c728185d4aeb7044ace: vfio/virtio: fix virtio-pci dependency (2024-01-10 15:10:41 -0700) ---------------------------------------------------------------- VFIO updates for v6.8-rc1 - Add debugfs support, initially used for reporting device migration state. (Longfang Liu) - Fixes and support for migration dirty tracking across multiple IOVA regions in the pds-vfio-pci driver. (Brett Creeley) - Improved IOMMU allocation accounting visibility. (Pasha Tatashin) - Virtio infrastructure and a new virtio-vfio-pci variant driver, which provides emulation of a legacy virtio interfaces on modern virtio hardware for virtio-net VF devices where the PF driver exposes support for legacy admin queues, ie. an emulated IO BAR on an SR-IOV VF to provide driver ABI compatibility to legacy devices. (Yishai Hadas & Feng Liu) - Migration fixes for the hisi-acc-vfio-pci variant driver. (Shameer Kolothum) - Kconfig dependency fix for new virtio-vfio-pci variant driver. (Arnd Bergmann) ---------------------------------------------------------------- Alex Williamson (2): Merge branches 'v6.8/vfio/debugfs', 'v6.8/vfio/pds' and 'v6.8/vfio/type1-account' into v6.8/vfio/next Merge branch 'v6.8/vfio/virtio' into v6.8/vfio/next Arnd Bergmann (1): vfio/virtio: fix virtio-pci dependency Brett Creeley (6): vfio/pds: Fix calculations in pds_vfio_dirty_sync vfio/pds: Only use a single SGL for both seq and ack vfio/pds: Move and rename region specific info vfio/pds: Pass region info to relevant functions vfio/pds: Move seq/ack bitmaps into region struct vfio/pds: Add multi-region support Feng Liu (4): virtio: Define feature bit for administration virtqueue virtio-pci: Introduce admin virtqueue virtio-pci: Introduce admin command sending function virtio-pci: Introduce admin commands Longfang Liu (3): vfio/migration: Add debugfs to live migration driver Documentation: add debugfs description for vfio MAINTAINERS: Add vfio debugfs interface doc link Pasha Tatashin (1): vfio/type1: account iommu allocations Shameer Kolothum (1): hisi_acc_vfio_pci: Update migration data pointer correctly on saving/resume Yishai Hadas (6): virtio-pci: Initialize the supported admin commands virtio-pci: Introduce APIs to execute legacy IO admin commands vfio/pci: Expose vfio_pci_core_setup_barmap() vfio/pci: Expose vfio_pci_core_iowrite/read##size() vfio/virtio: Introduce a vfio driver over virtio devices vfio/virtio: Declare virtiovf_pci_aer_reset_done() static Documentation/ABI/testing/debugfs-vfio | 25 ++ MAINTAINERS | 8 + drivers/vfio/Kconfig | 10 + drivers/vfio/Makefile | 1 + drivers/vfio/debugfs.c | 92 ++++ drivers/vfio/pci/Kconfig | 2 + drivers/vfio/pci/Makefile | 2 + drivers/vfio/pci/hisilicon/hisi_acc_vfio_pci.c | 7 +- drivers/vfio/pci/pds/dirty.c | 309 ++++++++----- drivers/vfio/pci/pds/dirty.h | 18 +- drivers/vfio/pci/vfio_pci_rdwr.c | 57 +-- drivers/vfio/pci/virtio/Kconfig | 15 + drivers/vfio/pci/virtio/Makefile | 3 + drivers/vfio/pci/virtio/main.c | 576 +++++++++++++++++++++++++ drivers/vfio/vfio.h | 14 + drivers/vfio/vfio_iommu_type1.c | 8 +- drivers/vfio/vfio_main.c | 4 + drivers/virtio/Kconfig | 5 + drivers/virtio/Makefile | 1 + drivers/virtio/virtio.c | 37 +- drivers/virtio/virtio_pci_admin_legacy_io.c | 244 +++++++++++ drivers/virtio/virtio_pci_common.c | 14 + drivers/virtio/virtio_pci_common.h | 42 +- drivers/virtio/virtio_pci_modern.c | 259 ++++++++++- drivers/virtio/virtio_pci_modern_dev.c | 24 +- include/linux/vfio.h | 7 + include/linux/vfio_pci_core.h | 20 + include/linux/virtio.h | 8 + include/linux/virtio_config.h | 4 + include/linux/virtio_pci_admin.h | 23 + include/linux/virtio_pci_modern.h | 2 + include/uapi/linux/vfio.h | 1 + include/uapi/linux/virtio_config.h | 8 +- include/uapi/linux/virtio_pci.h | 68 +++ 34 files changed, 1754 insertions(+), 164 deletions(-) create mode 100644 Documentation/ABI/testing/debugfs-vfio create mode 100644 drivers/vfio/debugfs.c create mode 100644 drivers/vfio/pci/virtio/Kconfig create mode 100644 drivers/vfio/pci/virtio/Makefile create mode 100644 drivers/vfio/pci/virtio/main.c create mode 100644 drivers/virtio/virtio_pci_admin_legacy_io.c create mode 100644 include/linux/virtio_pci_admin.h
