A new binary acpi table tests/data/acpi/pc/DSDT.roothp is added in order to unit test
the feature flag that can disable/enable root pci bus hotplug on i440fx. This feature was
added with the commit:
3d7e78aa7777f0 ("Introduce a new flag for i440fx to disable PCI hotplug on the root bus")
This change documents the fact that this new file addition was made as a part of the
unit test change.

When ACPI hotplug for the root bus is disabled, the bsel property for that
bus is not set. Please see the following commit:
3d7e78aa7777f ("Introduce a new flag for i440fx to disable PCI hotplug on the root bus").
As a result, when acpi_pcihp_find_hotplug_bus() is called
with bsel set to 0, it may return the root bus. This can cause devices attached to
the root bus to get hot-unplugged if the user issues the following set of commmands:
outl 0xae10 0
outl 0xae08 your_slot
Thanks to Julia for pointing this out here:
https://www.mail-archive.com/qemu-devel@nongnu.org/msg734548.html
In this patch, we fix the issue in this function by checking if the bus which is
returned by the function is actually hotpluggable. If not, we simply return NULL.
This avoids the scenario where we were returning a non-hotpluggable bus.

Cold plugged bridges are not hot unpluggable, even when their hotplug
property (acpi-pci-hotplug-with-bridge-support) is turned off. Please see
the function acpi_pcihp_pc_no_hotplug(). However, with
the current implementaton, Windows would try to hot-unplug a pci bridge when
it's hotplug switch is off. This is regardless of whether there are devices
attached to the bridge. This is because we add amls like _EJ0 etc for the
pci slot where the bridge is cold plugged.
In this fix, we identify a cold plugged bridge and for cold plugged bridges,
we do not add the appropriate acpi methods that are used by the OS
to identify a hot-pluggable/unpluggable pci device. After this change, Windows
does not detect the cold plugged pci bridge as ejectable.
As a result of the patch, the following are the changes to the DSDT ACPI

This change adds a new unit test for the global flag
'acpi-pci-hotplug-with-bridge-support' which is available for cold plugged pci
bridges in i440fx. The flag can be used to turn off acpi based hotplug support
on all pci bridges.

This patch adds a binary blob corresponding to the DSDT acpi table. It is used
to unit test the flag 'acpi-pci-hotplug-with-bridge-support' used with pci
bridges.
This change also clears the file tests/qtest/bios-tables-test-allowed-diff.h
so that future changes which affect the table can be caught.
The following is the diff between files tests/data/acpi/pc/DSDT.bridge and
tests/data/acpi/pc/DSDT.hpbridge after disassembly :

When acpi hotplug is turned off for both root pci bus as well as for pci
bridges, we should not generate the related acpi code for DSDT table or
initialize related hw ports or reserve hw resources. This change makes
sure all those operations are turned off in the case acpi pci hotplug is
off globally.
In this change, we also make sure AMLs for the PCNT method are only added when
bsel is enabled for the corresponding pci bus or bridge hotplug is turned on.
As a result, when the hotplug for both the root pci device and bridge are
disabled, this AML in the DSDT acpi table is turned off.
As q35 machines do not use bsel for it's pci buses at this point in time, this
change affects DSDT acpi table for q35 machines as well. Therefore, we also
commit the updated golden master DSDT table acpi binary blobs as well.
Following is a typical diff between the q35 acpi DSDT table blobs:

Please split binary blobs into separate patch, as described in process.
Otherwise the patch is very likely to become un-merge-able due to conflicts.

it would work if it were the only patch that touches ACPI,
process instructs splitting acpi changes in 3 part to avoid issues
with merging and bisecting. (it saves time not only of maintainer
but your as well)
Additionally, one can not review (without going into trouble of testing/disassembling)
binary blobs, so it's good to split them out into a separate patch.

This change adds a unit test to exercise the case when hotplug is disabled both for
pci root bus and the pci bridges by passing the following two switches to qemu:
-global PIIX4_PM.acpi-root-pci-hotplug=off
-global PIIX4_PM.acpi-pci-hotplug-with-bridge-support=off
bios-tables-test-allowed-diff.h documents the fact that a new DSDT acpi gold master
binary blob we need to be added to test this. We will do the actual addition in the
next patch in the series.

now there is mix of different styles on how test entries are named,
pls amend tests you are adding before that one to the same style.

This change adds a new DSDT golden master table blob to test disabling
hotplug on both pci root bus and pci bridges. Also reverts the change
in file bios-tables-test-allowed-diff.h to make sure its now empty so that
future modifications to acpi tables can be caught.
The following is the disassembled diff between DSDT.hpbridge and DSDT.hpbrroot:
