[libvirt] [PATCH 0/7] Improve GIC support

[Andrea Bolognani]

This series was really just supposed to enable guests to use the
special "host" GIC version, but I ended up changing a bunch of other
stuff and adding a whole lot of new test cases.

I've also made it so the GIC availability is always reflected in the
domain XML, the same way other implicit devices and features work.

The GIC-related definitions are in their own file: depending on
whether we end up probing for host GIC support ourselves or relying
on QEMU this might turn out to be a huge overkill :)

Cheers.


Andrea Bolognani (7):
  gic: Introduce virGICVersion enumeration
  schema: List allowed GIC versions
  conf: Use virGICVersion enumeration in virDomainDef
  qemu: Default to GIC v2
  qemu: Always enable GIC on ARM virt machines
  tests: Reorganize and simplify GIC test cases
  tests: Add more GIC test cases
