Document usage as limited to emulated IOMMU devices, ie. traditional mdev devices where this restriction is consistent (Jason Gunthorpe) - Correct function prefix in hisi_acc driver incurred during previous refactoring (Shameer Kolothum) - Correct typo and remove redundant warning triggers in vfio-fsl driver (Christophe JAILLET) - Introduce device level DMA dirty tracking uAPI and implementation in the mlx5 variant driver (Yishai Hadas & Joao Martins) - Move much of the vfio_device life cycle management into vfio core, simplifying and avoiding duplication across drivers. This also facilitates adding a struct device to vfio_device which begins the introduction of device rather than group level user support and fills a gap allowing userspace identify devices as vfio capable without implicit knowledge of the driver (Kevin Tian & Yi Liu) - Split vfio container handling to a separate file, creating a more well defined API between the core and container code, masking IOMMU backend implementation from the core, allowing for an easier future transition to an iommufd based implementation of the same (Jason Gunthorpe) - Attempt to resolve race accessing the iommu_group for a device between vfio releasing DMA ownership and removal of the device from the IOMMU driver. Follow-up with support to allow vfio_group to exist with NULL iommu_group pointer to support existing userspace use cases of holding the group file open (Jason Gunthorpe) - Fix error code and hi/lo register manipulation issues in the hisi_acc variant driver, along with various code cleanups (Longfang Liu) - Fix a prior regression in GVT-g group teardown, resulting in unreleased resources (Jason Gunthorpe) - A significant cleanup and simplification of the mdev interface, consolidating much of the open coded per driver sysfs interface support into the mdev core (Christoph Hellwig) - Simplification of tracking and locking around vfio_groups that fall out from previous refactoring (Jason Gunthorpe) - Replace trivial open coded f_ops tests with new helper (Alex Williamson) * tag 'vfio-v6.1-rc1' of https://github.com/awilliam/linux-vfio: (77 commits) vfio: More vfio_file_is_group() use cases vfio: Make the group FD disassociate from the iommu_group vfio: Hold a reference to the iommu_group in kvm for SPAPR vfio: Add vfio_file_is_group() vfio: Change vfio_group->group_rwsem to a mutex vfio: Remove the vfio_group->users and users_comp vfio/mdev: add mdev available instance checking to the core vfio/mdev: consolidate all the description sysfs into the core code vfio/mdev: consolidate all the available_instance sysfs into the core code vfio/mdev: consolidate all the name sysfs into the core code vfio/mdev: consolidate all the device_api sysfs into the core code vfio/mdev: remove mtype_get_parent_dev vfio/mdev: remove mdev_parent_dev vfio/mdev: unexport mdev_bus_type vfio/mdev: remove mdev_from_dev vfio/mdev: simplify mdev_type handling vfio/mdev: embedd struct mdev_parent in the parent data structure vfio/mdev: make mdev.h standalone includable drm/i915/gvt: simplify vgpu configuration management drm/i915/gvt: fix a memory leak in intel_gvt_init_vgpu_types ... 2022-10-08T00:04:10Z Linus Torvalds torvalds@linux-foundation.org 2022-10-08T00:04:10Z urn:sha1:e8bc52cb8df80c31c73c726ab58ea9746e9ff734 Pull driver core updates from Greg KH: "Here is the big set of driver core and debug printk changes for 6.1-rc1.
