This totally depends on the NIC or other devices' vendors and they
should make decision to support migration or not. If yes, they would
modify driver.
If just target to call suspend/resume during migration, the feature will
be meaningless. Most cases don't want to affect user during migration
a lot and so the service down time is vital. Our target is to apply
SRIOV NIC passthough to cloud service and NFV(network functions
virtualization) projects which are sensitive to network performance
and stability. From my opinion, We should give a change for device
driver to implement itself migration job. Call suspend and resume
callback in the driver if it doesn't care the performance during migration.

This is why I hope to reserve a piece of space in the dma page to do
dummy write. This can help to mark page dirty while not require to stop
DMA and not race with DMA data.
If can't do that, we have to stop DMA in a short time to mark all dma
pages dirty and then reenable it. I am not sure how much we can get by
this way to track all DMA memory with device running during migration. I
need to do some tests and compare results with stop DMA diretly at last
stage during migration.

I don't think there is such events in the current spec.
Otherwise, There are two kinds of suspend/resume callbacks.
1) System suspend/resume called during S2RAM and S2DISK.
2) Runtime suspend/resume called by pm core when device is idle.
If you want to do what you mentioned, you have to change PM core and
ACPI spec.
