Lilu DeviceInfo detection precludes MacHyperVSupport PCI bridges

[flagersgit]

As title mentions, Lilu's DeviceInfo class does not consider MacHyperVSupport PCI bridges.

This is understandably so, because the Hyper-V Gen 2 VM topology is rather weird and nothing alike a normal PC, but nonetheless still problematic.

For example, GPUs (and accompanying HDA) passed to VMs will not have the benefit of patches being applied by WhateverGreen and AppleALC.

Fair enough, but given MacHyperVSupport starts late I really wonder whether we actually can support these. Most likely Lilu will not see these devices. Have you tried to patch Lilu to support this?

I haven't tried to patch Lilu yet.

I was considering some approaches to solving this problem.
Perhaps Lilu can route IOPCIBridge::publishNub to see the devices as soon as possible (immediately after they are published children of the HyperVPCIBridge). Will, of course, have to test and see.

EDIT: On second thought, I think even with that, WhateverGreen would still be ahead of the Hyper-V PCI bridge start.
