Bug description:
[Impact]
Numerous issues triggered from AER/DPC services
- When AER is shared with PME, cutting the power off the device can trigger
AER IRQ. Since AER IRQ is shared with PME, it's treated like a wakeup source,
preventing the system from entering sleep.
- When system resume from S3, device can reset itself and start
sending PTM messages, triggering AER and reset the entire hierarchy.
Since the hardware/firmware starts before software, it's never soon
enough to put a band-aid from kernel.
- Following above one, device firmware restarts before kernel resume,
when DPC is triggered then the device is gone without any recovering
method. We really want to prevent that from happening.
[Fix]
Disable and re-enable AER and DPC services on suspend and resume,
respectively.
Right now the the PCI mailing list doesn't have a consensus which PCI state
(D3hot vs D3cold) should the AER/DPC services should be disabled, so re-instate
the old workaround for now.
[Test]
One the workaround is applied, symptoms described above can no longer be
observed.
[Where problems could occur]
Theoretically there can be some "real" issues get unnoticed once AER gets
temporarily disabled, but the benefit far outweighs the downside.
