[PATCH v5 00/18] pci hotplug tracking

[Vladimir Sementsov-Ogievskiy]

Hi all!

v5: - don't deprecate IDs and return to ID & QOM scheme
    - split complicated HOTPLUG_STATE patch into several ones

----

The main patches are the last four ones:

- introduce HOTPLUG_STATE event, that inform when hotplug controller
change it's state, especially indicator leds

- query-hotplug command, that provides same information as event on
demand

- DEVICE_ON event - a kind of counterpart for DEVICE_DELETED, signals
when device is finally accepted by guest, power indicator is on and so
on.

That's all for smarter handling of SHPC and PCIe-native hotplug.

If you want to test new events, don't forget
  -global ICH9-LPC.acpi-pci-hotplug-with-bridge-support=off
flag, to disable ACPI hotplug default.

Vladimir Sementsov-Ogievskiy (18):
  pci/shpc: set attention led to OFF on reset
  pci/shpc: change shpc_get_status() return type to uint8_t
  pci/shpc: shpc_slot_command(): handle PWRONLY -> ENABLED transition
  pci/shpc: more generic handle hot-unplug in shpc_slot_command()
  pci/shpc: pass PCIDevice pointer to shpc_slot_command()
  pci/shpc: refactor shpc_device_plug_common()
  pcie: pcie_cap_slot_write_config(): use correct macro
  pcie_regs: drop duplicated indicator value macros
  pcie: drop unused PCIExpressIndicator
  pcie: pcie_cap_slot_enable_power() use correct helper
  pcie: introduce pcie_sltctl_powered_off() helper
  pcie: set power indicator to off on reset by default
  pci: introduce pci_find_the_only_child()
  qapi/qdev.json: unite DEVICE_* event data into single structure
  qapi: add HOTPLUG_STATE infrastructure
  shpc: implement HOTPLUG_STATE event and query-hotplug
  pcie: implement HOTPLUG_STATE event and query-hotplug
  qapi: introduce DEVICE_ON event
