[Qemu-devel] [PATCH v12 00/15] vfio-pci: pass the aer error to guest |

From: Chen Fan <address@hidden>
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.
Chen Fan (15):
vfio: extract vfio_get_hot_reset_info as a single function
vfio: squeeze out vfio_pci_do_hot_reset for support bus reset
pcie: modify the capability size assert
vfio: make the 4 bytes aligned for capability size
vfio: add pcie extanded capability support
aer: impove pcie_aer_init to support vfio device
vfio: add aer support for vfio device
vfio: add check host bus reset is support or not
pci: add bus reset_notifiers callbacks for host bus reset
vfio: add sec_bus_reset notifier to notify physical bus reset is
needed
vfio: modify vfio_pci_hot_reset to support bus reset
vfio: do hot bus reset when do virtual secondary bus reset
pcie_aer: expose pcie_aer_msg() interface
vfio-pci: pass the aer error to guest
vfio: add 'aer' property to expose aercap
