Subject: [Qemu-devel] [RFC v10 00/19] vfio-pci: pass the aer error to guest
Date: Tue, 16 Jun 2015 16:10:44 +0800	[thread overview]
Message-ID: <cover.1434356309.git.chen.fan.fnst@cn.fujitsu.com> (raw)

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.

v9-v10:
   1. support vfio_get_group with as is NULL. keep group into container.

v8-v9:
   1. add ref to group for devices supported aer could own the group
      without devices in VM.
   2. add check for all aer devices if conflict the topology at each
      initfn time.

Chen Fan (19):
  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 ref for group to support own affected groups
  vfio: extract vfio_register_container_listener from
    vfio_connect_container
  vfio: improve vfio_get_group to support adding as is NULL.
  get all affected groups for each device support aer
  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: improve vfio_pci_hot_reset to support more case
  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
