[Qemu-devel] [PATCH 1/6] spapr: Start hotplugged PCI devices in ISOLATED state

2017-06-07 Thread David Gibson
PCI DRCs, and only PCI DRCs, are immediately moved to UNISOLATED isolation state once the device is attached. This has been there from the initial implementation, and it's not clear why. The state diagram in PAPR 13.4 suggests PCI devices should start in ISOLATED state until the guest moves them
