[Qemu-devel] [PATCH 00/30] complete conversion to hotplug-handler API


From: Igor Mammedov
Subject: [Qemu-devel] [PATCH 00/30] complete conversion to hotplug-handler API
Date: Wed, 24 Sep 2014 11:47:49 +0000

Series unifies different hotplug mechanisms to a recent
hotplug-handler API and does shallow conversion of
devices that still use legacy qdev hotplug to it dropping
not used after that legacy hotplug path [29/30].
It also relaces SCSI's own way to do hotplug/unplug with
hotplug-handler callbacks leaving it the only method
perform hotplug tasks.
And the last patch [30/30] allows to unplug of BUS-less
devices using hotplug-handler API.

Converted devices are covered with new hotplug
unit-tests, except of:
 s390x-*: I have no idea how or means to test it, but code
          is close to virtio, so it's converted using
          virtio template
 pvscsi: is broken, so no means to test it

Igor Mammedov (30):
  test: virtio-scsi: check if hot-plug/unplug works
  test: virtio-serial: check if hot-plug/unplug works
  test: virtio-rng: check if hot-plug/unplug works
  test: virtio-net: check if hot-plug/unplug works
  test: virtio-blk: check if hot-plug/unplug works
  test: usb: add port test to uhci unit test
  test: usb: generic usb device hotplug
  test: usb: usb-storage hotplug test
  access BusState.allow_hotplug using wraper qbus_is_hotpluggable()
  qdev: HotplugHandler: rename unplug callback to unplug_request
  qdev: HotplugHandler: provide unplug callback
  qdev: add simple/generic unplug callback for HotplugHandler
  qdev: hotplug: set handler only if HOTPLUG_HANDLER interface is
    supported
  target-i386: ICC bus: replace BusState.allow_hotplug with
    hotplug_handler
  virtio-pci: replace BusState.allow_hotplug with hotplug_handler
  virtio-serial: convert to hotplug-handler API
  virtio-mmio: drop useless bus->allow_hotplug = 0
  s390x: drop not used allow_hotplug in event-facility
  s390x: convert s390-virtio to hotplug handler API
  s390x: convert virtio-ccw to hotplug handler API
  scsi: make scsi_bus_new() assign hotplug controller
  scsi: convert pvscsi HBA to hotplug hander API
  scsi: convert virtio-scsi HBA to hotplug handler API
  scsi: cleanup not used anymore SCSIBusInfo{hotplug,hot_unplug} fields
  usb-bot: drop not needed "allow_hotplug = 0"
  usb-storage: make its storage SCSI bus hotpluggable explicitly
  usb-storage: drop not needed "allow_hotplug = 0"
  usb: convert to hotplug handler API
  qdev: drop legacy hotplug fields/methods
  qdev: HotplugHandler: add support for unplugging BUS-less devices
