[libvirt] [PATCH v3 0/6] PCI hostdev partial assignment support

Posted by Daniel Henrique Barboza 1 week ago
changes from previous version [1]:
- do not overload address type='none'. A new address type called
'unassigned' is introduced;
- there is no unassigned' flag being created in virDomainHostdevDef.
The logic added by new address type is enough;
- do not allow function zero of multifunction devices to be
unassigned.

Nothing too special to discuss in this cover letter. More details
can be found at the discussions of the previous version [1]. Commit
messages of the patches have more background info as well.

  virhostdev.c: check all IOMMU devs in virHostdevPreparePCIDevices
  formatdomain.html.in: document <address type='unassigned'/>
  utils: PCI multifunction detection helpers
  domain_conf.c: don't allow function zero to be unassigned
