In v4 I have made the following changes:
- a cosmetic change for patch #4. Commit log was updated as per Igor's suggestion.
- patches #10 and #11 were added to unit test patch #9.
The DSDT table after disabling hotplug on the root bus and the pci bridges is shown here:
https://pastebin.ubuntu.com/p/WvpYYjpPN8/
This was generated by disassembling the newly added DSDT golden master binary table blob
DSDT.hpbrroot.
I sincerely hope this is the final iteration of the set of patches. The patches has been
unit tested on top of latest qemu upstream master branch.

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.

A new binary ACPI table tests/data/acpi/pc/DSDT.roothp is added in order
to unit test hotplug on/off capability on the root pci bus for i440fx.
The diff between the table DSDT.bridge and DSDT.roothp is listed below:

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() (thanks Julia). 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. We have a demo video here:
https://youtu.be/pME2sjyQweo
In this fix, we identify a cold plugged bridge and for cold plugged bridges,
we do not add the appropriate amls and acpi methods that are used by the OS
to identify a hot-pluggable/unpluggable pci device. After this change, Windows
does not show an option to eject the PCI bridge. A demo video is here:
https://youtu.be/kbgej5B9Hgs

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
for 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 amls 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:

This change adds a unit test to exercize 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.
The following link contains the disassembly of the DSDT table after passing the above
two switches to qemu: https://pastebin.ubuntu.com/p/WvpYYjpPN8/

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:

try to not use links in commit message especially ephemeral ones
that tend to disappear with time.
Description in commit message should be sufficient to describe issue.
it's fine to give links under --- line as additional info to support
the case and that gets discarded when patch is applied.

ditto and fix the same in other patches.
I'd also try format commit message so line length

You could use:
test data = {
.machine = MACHINE_PC;
.variant = ".hpbrroot";
};
... then you don't need the memset() call anymore.

It seems the tests which initialize data that way are the ones which
have more test attributes to set in data. Most tests does a memset. So
I will leave the memset as is for now.
