Hi Linus, The following changes since commit b6cd17050bc0817c79924f23716198b2e935556e: Merge tag 'vfio-v6.6-rc4' of https://github.com/awilliam/linux-vfio (2023-09-27 09:33:55 -0700) are available in the Git repository at: https://github.com/awilliam/linux-vfio.git tags/vfio-v6.7-rc1 for you to fetch changes up to 2b88119e35b00d8cb418d86abbace3b90a993bd7: vfio/mtty: Enable migration support (2023-10-24 15:03:10 -0600) ---------------------------------------------------------------- VFIO updates for v6.7 - Add support for "chunk mode" in the mlx5-vfio-pci variant driver, which allows both larger device image sizes for migration, beyond the previous 4GB limit, and also read-ahead support for improved migration performance. (Yishai Hadas) - A new bus master control interface for the CDX bus driver where there is no in-band mechanism to toggle device DMA as there is through config space on PCI devices. (Nipun Gupta) - Add explicit alignment directives to vfio data structures to reduce the chance of breaking 32-bit userspace. In most cases this is transparent and the remaining cases where data structures are padded work within the existing rules for extending data structures within vfio. (Stefan Hajnoczi) - Resolve a bug in the cdx bus driver noted when compiled with clang where missing parenthesis result in the wrong operation. (Nathan Chancellor) - Resolve errors reported by smatch for a function when dealing with invalid inputs. (Alex Williamson) - Add migration support to the mtty vfio/mdev sample driver for testing and integration purposes, allowing CI of migration without specific hardware requirements. Also resolve many of the short- comings of this driver relative to implementation of the vfio interrupt ioctl along the way. (Alex Williamson) ---------------------------------------------------------------- Alex Williamson (4): Merge branch 'mlx5-vfio' of https://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux into v6.7/vfio/next vfio: Fix smatch errors in vfio_combine_iova_ranges() vfio/mtty: Overhaul mtty interrupt handling vfio/mtty: Enable migration support Nathan Chancellor (1): vfio/cdx: Add parentheses between bitwise AND expression and logical NOT Nipun Gupta (3): cdx: add support for bus mastering vfio: add bus master feature to device feature ioctl vfio-cdx: add bus mastering device feature support Stefan Hajnoczi (3): vfio: trivially use __aligned_u64 for ioctl structs vfio: use __aligned_u64 in struct vfio_device_gfx_plane_info vfio: use __aligned_u64 in struct vfio_device_ioeventfd Yishai Hadas (9): net/mlx5: Introduce ifc bits for migration in a chunk mode vfio/mlx5: Wake up the reader post of disabling the SAVING migration file vfio/mlx5: Refactor the SAVE callback to activate a work only upon an error vfio/mlx5: Enable querying state size which is > 4GB vfio/mlx5: Rename some stuff to match chunk mode vfio/mlx5: Pre-allocate chunks for the STOP_COPY phase vfio/mlx5: Add support for SAVING in chunk mode vfio/mlx5: Add support for READING in chunk mode vfio/mlx5: Activate the chunk mode functionality drivers/cdx/cdx.c | 32 ++ drivers/cdx/controller/cdx_controller.c | 4 + drivers/cdx/controller/mcdi_functions.c | 58 +++ drivers/cdx/controller/mcdi_functions.h | 13 + drivers/gpu/drm/i915/gvt/kvmgt.c | 2 +- drivers/vfio/cdx/main.c | 57 ++- drivers/vfio/cdx/private.h | 2 + drivers/vfio/pci/mlx5/cmd.c | 103 ++-- drivers/vfio/pci/mlx5/cmd.h | 28 +- drivers/vfio/pci/mlx5/main.c | 283 ++++++++--- drivers/vfio/vfio_main.c | 10 + include/linux/cdx/cdx_bus.h | 18 + include/linux/mlx5/mlx5_ifc.h | 15 +- include/uapi/linux/vfio.h | 47 +- samples/vfio-mdev/mbochs.c | 2 +- samples/vfio-mdev/mdpy.c | 2 +- samples/vfio-mdev/mtty.c | 829 +++++++++++++++++++++++++++++--- 17 files changed, 1309 insertions(+), 196 deletions(-)
