Hi,
The first 6 patches of [1] are all VFIO or IOMMUFD related additions.
Split them out per Cédric and seek for quick acceptance.
I didn't copy changelog from [1] as it's a mix of the whole nesting series.
For who want a quick view of the whole nesting series [2].
Test done:
- VFIO devices hotplug/unplug
- build test on Windows
[1] https://lists.gnu.org/archive/html/qemu-devel/2025-05/msg05002.html

Thanks

Changelog:
v2:
- report kernel BUG as error instead of assert (Cédric)
- merge patch2 and patch3 (Cédric)
- handle vendor cap check directly from vtd_check_hiod, so patch6 removed
(Cédric)
- s/data_ptr/data (Cédric)
- s/totally/total (Donald)
Applied to vfio-next.
Thanks,
C.
v1:
- changed to save raw data in VendorCaps, so we can keep all vendor structure
decoding inside the backend and VFIO wouldn't need to care about types nor
what's inside the data.
