type
Git-commit: c318bef76206c2ecb6016e8e68c4ac6ff9a4c8cb
References: bsc#1192147
To solve issues [1-2] the Hot Plug Capable bit in PCIe Slots will be
turned on, while the switch to ACPI Hot-plug will be done in the
DSDT table.

Subject: hw/i386/acpi-build: Deny control on PCIe Native Hot-plug in _OSC
Git-commit: 211afe5c69b597acf85fdd577eb497f5be1ffbd8
References: bsc#1192147
There are two ways to enable ACPI PCI Hot-plug:
* Disable the Hot-plug Capable bit on PCIe slots.
This was the first approach which led to regression [1-2], as
I/O space for a port is allocated only when it is hot-pluggable,
which is determined by HPC bit.
* Leave the HPC bit on and disable PCIe Native Hot-plug in _OSC
method.
This removes the (future) ability of hot-plugging switches with PCIe
Native hotplug since ACPI PCI Hot-plug only works with cold-plugged
bridges. If the user wants to explicitely use this feature, they can
disable ACPI PCI Hot-plug with:
--global ICH9-LPC.acpi-pci-hotplug-with-bridge-support=off
Change the bit in _OSC method so that the OS selects ACPI PCI Hot-plug
instead of PCIe Native.

Subject: pcie: rename 'native-hotplug' to 'x-native-hotplug'
Git-commit: 2aa1842d6d79dcd1b84c58eeb44591a99a9e56df
References: bsc#1192147
Mark property as experimental/internal adding 'x-' prefix.
Property was introduced in 6.1 and it should have provided
ability to turn on native PCIE hotplug on port even when
ACPI PCI hotplug is in use is user explicitly sets property
on CLI. However that never worked since slot is wired to
ACPI hotplug controller.
Another non-intended usecase: disable native hotplug on slot
when APCI based hotplug is disabled, which works but slot has
'hotplug' property for this taks.
It should be relatively safe to rename it to experimental
as no users should exist for it and given that the property
is broken we don't really want to leave it around for much
longer lest users start using it.
