[Qemu-devel] [PATCH v2 00/12] Convert VFIO-PCI to realize

[Eric Auger]

This series converts VFIO-PCI to realize. It also aims at improving
the error reporting in case of QMP hot-plug.

Before the series, a device_add failure would have reported:
{"error": {"class": "GenericError", "desc": "Device initialization
failed"}}.

Now the actual error cause is reported.

Git Information:
https://github.com/eauger/qemu/tree/v2.7.0_vfio_realize_v2

History:
v1 -> v2:
- Error object is cascaded downto vfio_intx_enable, vfio_add_capabilities
  vfio_pci_igd_opregion_init, vfio_get_group, vfio_get_device
- Actual migration to realize happens at a later stage following Markus'
  guidance
- special handling of the case where the end-user omits the host property
- error_setg_errno now uses positive errno
- more detailed commit message
- fix "cannot enable AER cannot" functional change

Eric Auger (12):
  vfio/pci: Use local error object in vfio_initfn
  vfio/pci: Pass an error object to vfio_populate_device
  vfio/pci: Pass an error object to vfio_msix_early_setup
  vfio/pci: Pass an error object to vfio_intx_enable
  vfio/pci: Pass an error object to vfio_add_capabilities
  vfio/pci: Pass an error object to vfio_pci_igd_opregion_init
  vfio: Pass an error object to vfio_get_group
  vfio: Pass an error object to vfio_get_device
  vfio/pci: Conversion to realize
  vfio/pci: Remove vfio_msix_early_setup returned value
  vfio/pci: Remove vfio_populate_device returned value
  vfio/pci: Handle host oversight
