[Qemu-devel] [PATCH v16 00/14] vfio-pci: pass the aer error to guest |

From: Chen Fan <address@hidden>
For now, for vfio pci passthough devices when qemu receives
an error from host aer report, currentlly just terminate the guest,
but usually user want to know what error occurred but stopping the
guest, so this patches add aer capability support for vfio device,
and pass the error to guest, and have guest driver to recover
from the error.
v15-v16:
10/14, 11/14 are new to introduce a reset sequence id to specify the
vfio devices has been reset for that reset. other patches aren't modified.
v14-v15:
1. add device hot reset callback
2. add bus_in_reset for vfio device to avoid multi do host bus reset
v13-v14:
1. for multifunction device, requiring all functions enable AER.(9/13)
2. due to all affected functions receive error signal, ignore no
error occurred function. (12/13)
v12-v13:
1. since support multifuncion hotplug, here add callback to enable aer.
2. add pci device pre+post reset for aer host reset.
Chen Fan (14):
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
add check reset mechanism when hotplug vfio device
pci: introduce pci bus pre reset
vfio: introduce last reset sequence id
pcie_aer: expose pcie_aer_msg() interface
vfio-pci: pass the aer error to guest
vfio: add 'aer' property to expose aercap
