[Qemu-devel] [PATCH v4 00/17] Convert VFIO-PCI to realize |

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.
A side effect of this series is the cleanup of the error handling
in vfio-platform.
Git Information:
https://github.com/eauger/qemu/tree/v2.7.0_vfio_realize_v4
History:
v3 -> v4:
- added vfio: Pass an Error object to vfio_connect_container
v2 -> v3:
- Addressed Markus' comments :
- don't use local error object if not necessary
- fix some error handling: see individual patches
- use error objects also on vfio platform realize path although
hot-plug is not allowed, but that's cleaner I think.
- bug fix in vfio platform
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
