From: Chen Fan <chen.fan.f...@cn.fujitsu.com>
For now, when qemu receives an error from host aer report
by vfio pci passthough devices, qemu just terminate the guest.
Usually user want to know what error occurred
rather than stop the guest.
This patches add aer capability support for vfio device,
then pass the error to guest, and let guest driver to recover
from the error.
Turning on SERR# for error forwording in bridge control register
patch in seabios has been merged as commit 32ec3ee.
notes:
this series patches enable aer support single/multi-function,
for multi-function, require all the function of the slot assigned to
VM and on the same slot.
