For now, for vfio pci passthough devices when qemu receives
an error from host aer report, there just terminate the guest,
but usually user want to know what error occurred but stop 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.
and turning on SERR# for error forwording in bridge control register
patch in seabios has been merged.
v8-v8.1:
1. add check the case when one aer devices is re-hotplugged
to upper bus which will conflict the present which enable aer.
2. add vfio_pci_affect_devices_is_multi to specify signal or
multi in-use when call hot reset.
v7-v8:
1. some bug fixes requested by Alex
v6-v7:
1. add has_bus_reset to support reset host bus.
v5-v6:
1. add secondary bus callbacks to reset host bus.
v3-v4:
1. add 'x-aer' for user to off aer capability.
2. refactor vfio device to parse extended capabilities.
v2-v3:
1. refactor vfio device to parse extended capability.
2. add global property for piix4 to disable vfio aer cap.
v1-v2:
1. turn on SERR# for bridge control register in firmware.
2. initilize aer capability for vfio device.
3. fix some trivial bug.
Chen Fan (13):
vfio: extract vfio_get_hot_reset_info as a single function
vfio: squeeze out vfio_pci_do_hot_reset for support bus reset
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
vfio: add check for vfio devices which enable aer should support bus
reset
pci: add bus reset_notifiers callbacks for host bus reset
vfio: add sec_bus_reset notifier to notify physical bus reset is
needed
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
