Subject: [PATCH 00/12] vfio: selftests: Support for multi-device tests
Date: Wed, 8 Oct 2025 23:25:19 +0000 [thread overview]
Message-ID: <20251008232531.1152035-1-dmatlack@google.com> (raw)
This series adds support for tests that use multiple devices, and adds
one new test, vfio_pci_device_init_perf_test, which measures parallel
device initialization time to demonstrate the improvement from commit
e908f58b6beb ("vfio/pci: Separate SR-IOV VF dev_set").
This series also breaks apart the monolithic vfio_util.h and
vfio_pci_device.c into separate files, to account for all the new code.
This required some code motion so the diffstat looks large. The final
layout is more granular and provides a better separation of the IOMMU
code from the device code.
C files:
- tools/testing/selftests/vfio/lib/libvfio.c
- tools/testing/selftests/vfio/lib/iommu.c
- tools/testing/selftests/vfio/lib/vfio_pci_device.c
- tools/testing/selftests/vfio/lib/vfio_pci_driver.c
H files:
- tools/testing/selftests/vfio/lib/include/libvfio.h
- tools/testing/selftests/vfio/lib/include/libvfio/assert.h
- tools/testing/selftests/vfio/lib/include/libvfio/iommu.h
- tools/testing/selftests/vfio/lib/include/libvfio/vfio_pci_device.h
- tools/testing/selftests/vfio/lib/include/libvfio/vfio_pci_driver.h
Notably, vfio_util.h is now gone and replaced with libvfio.h.
This series is based on vfio next, and can be found on GitHub:
