[Qemu-devel] [PATCH v2 00/13] spapr: Add support for PHB hotplug

Posted by Greg Kurz 5 days ago
This allows to hotplug/unplug PHBs. I could successfully test:
- hotplug/unplug with e1000 device to validate LSIs
- hotplug/unplug with virtio-net device to validate MSIs
- some simple migration scenarios

Changes in v2:
- rebased on current ppc-for-4.0
- added some preliminary cleanup
- call unrealize from realize error path
- advertise PHB hotplug in last patch
- reworked phandle related code
- sync LSIs to KVM

Please comment.

David,

I had enough remarks from Cedric to go for a v3. I expect to send
it shortly. Don't spend time on reviewing the v2.
