  vfio: selftests: Ensure libvfio output dirs are always created (2026-06-12 10:25:44 -0600)

----------------------------------------------------------------
VFIO updates for v7.2-rc1

 - Fix out-of-tree vfio selftest builds with make O=. (Jason Gunthorpe)

 - Allow vfio selftests to build when ARCH=x86 is used for 64-bit x86
   builds. (David Matlack)

 - Tighten vfio selftest infrastructure with stricter builds, safer
   path handling, sysfs helpers, and reusable device/VF-token setup.
   Build on that to add the SR-IOV UAPI selftest across supported
   IOMMU modes. (Raghavendra Rao Ananta)

 - Conclude earlier vfio PCI BAR work already taken as v7.1 fixes by
   replacing vfio_pci_core_setup_barmap() and direct barmap[] access
   with vfio_pci_core_get_iomap().  Fix resulting sparse warnings.
   (Matt Evans)

 - Simplify hisi_acc vfio-pci variant driver device-info reads by
   using the mailbox's new direct command-based read helper.
   (Weili Qian)

 - Avoid duplicate reset handling in the Xe vfio-pci variant driver
   reset-done path. (GuoHan Zhao)

 - Resolve a lockdep circular dependency splat by tracking active
   VFs with a private sriov_active flag rather than calling
   pci_num_vf() under memory_lock. (Raghavendra Rao Ananta)

 - Add CXL DVSEC-based readiness polling for Blackwell-Next in the
   nvgrace-gpu vfio-pci variant driver, including interruptible,
   lockless waits to support worst case spec defined timeouts.
   (Ankit Agrawal)

 - Prevent vfio_mig_get_next_state() from spinning forever on blocked
   migration state transition. (Junrui Luo)

 - Fix a qat vfio variant driver migration resume race by taking the
   migration file lock before boundary checks. (Giovanni Cabiddu)

 - Add explicit dependencies between vfio selftest output object files
   and output directories to ensure directories are always created.
   (David Matlack)
