Hi Linus, The following changes since commit 81983758430957d9a5cb3333fe324fd70cf63e7e: Linux 6.12-rc5 (2024-10-27 12:52:02 -1000) are available in the Git repository at: https://github.com/awilliam/linux-vfio.git tags/vfio-v6.13-rc1 for you to fetch changes up to fe4bf8d0b6716a423b16495d55b35d3fe515905d: vfio/pci: Properly hide first-in-list PCIe extended capability (2024-11-25 08:34:22 -0700) ---------------------------------------------------------------- VFIO updates for v6.13 - Constify an unmodified structure used in linking vfio and kvm. (Christophe JAILLET) - Add ID for an additional hardware SKU supported by the nvgrace-gpu vfio-pci variant driver. (Ankit Agrawal) - Fix incorrect signed cast in QAT vfio-pci variant driver, negating test in check_add_overflow(), though still caught by later tests. (Giovanni Cabiddu) - Additional debugfs attributes exposed in hisi_acc vfio-pci variant driver for migration debugging. (Longfang Liu) - Migration support is added to the virtio vfio-pci variant driver, becoming the primary feature of the driver while retaining emulation of virtio legacy support as a secondary option. (Yishai Hadas) - Fixes to a few unwind flows in the mlx5 vfio-pci driver discovered through reviews of the virtio variant driver. (Yishai Hadas) - Fix an unlikely issue where a PCI device exposed to userspace with an unknown capability at the base of the extended capability chain can overflow an array index.
