Our side, Yu He, Lixiao Yang has done below tests on Intel platform with
the above kernel, results are:
1) GVT-g test suit passed, Intel iGFx passthrough passed.
2) NIC passthrough test with different guest memory (1G/4G), passed.
3) Booting two different QEMUs in the same time but one QEMU opens
legacy /dev/vfio/vfio and another opens /dev/iommu. Tests passed.
4) Tried below Kconfig combinations, results are expected.
VFIO_CONTAINER=y, IOMMUFD=y -- test pass
VFIO_CONTAINER=y, IOMMUFD=n -- test pass
VFIO_CONTAINER=n, IOMMUFD=y , IOMMUFD_VFIO_CONTAINER=y -- test pass
VFIO_CONTAINER=n, IOMMUFD=y , IOMMUFD_VFIO_CONTAINER=n -- no
/dev/vfio/vfio, so test fail, expected
5) Tested devices from multi-device group. Assign such devices to the same
VM, pass; assign them to different VMs, fail; assign them to a VM with Intel
virtual VT-d, fail; Results are expected.
Meanwhile, I also tested the branch in development branch for nesting,
the basic functionality looks good.

Great thanks!
you are welcome. this is a team work. :)
In future I also recommend running tests with the CONFIG_IOMMUFD_TEST
turned on, it enables a bunch more fast path assertions that might
catch something interesting
oh, sure. will try.
