Subject: [PATCH] conf: add new PCI_CONNECT flag AUTOASSIGN
b971b8
b971b8
This new flag will be set for any controller that we decide can have
b971b8
devices assigned to it automatically during PCI device assignment. In
b971b8
the past PCI_CONNECT_TYPE_HOTPLUGGABLE was used for this purpose, but
b971b8
that is overloading that flag, and no longer technically correct; what
b971b8
we *really* want is to auto-assign devices to any pcie-root-port or
b971b8
pcie-switch-downstream-port regardless of whether or not that
b971b8
controller happens to have hotplug enabled.
b971b8
b971b8
This patch just adds the flag, but doesn't use it at all. Note that
b971b8
the numbering of all the other flags was changed in order to insert
b971b8
the new flag near the beginning of the list; that doesn't cause any
b971b8
problem because the connect flags aren't stored anywhere between runs
b971b8
of libvirtd.
