This patchset adds a unit test to exercize acpi hotplug support for multifunction
bridges on q35 machines. This support was added with the commit:
d7346e614f4ec ("acpi: x86: pcihp: add support hotplug on multifunction bridges")
changelist:
v1 : initial RFC patch.
v2: incorporated some of the feedbacks from Igor.
v3: forgot to add the ASL diff for patch 3 in commit log for v2. Added now.

We are adding a new unit test to cover the acpi hotplug support in q35 for
multi-function bridges. This test uses a new table DSDT.multi-bridge.
We need to allow changes in DSDT acpi table for addition of this new
unit test.

commit d7346e614f4ec ("acpi: x86: pcihp: add support hotplug on multifunction bridges")
added ACPI hotplug descriptions for cold plugged bridges for functions other
than 0. For all other devices, the ACPI hotplug descriptions are limited to
function 0 only. This change adds unit tests for this feature.
This test adds the following devices to qemu and then checks the changes
introduced in the DSDT table due to the addition of the following devices:
(a) a multifunction bridge device
(b) a bridge device with function 1
(c) a non-bridge device with function 2
In the DSDT table, we should see AML hotplug descriptions for (a) and (b).
For (a) we should find a hotplug AML description for function 0.
The following diff compares the DSDT table AML with the new unit test before
and after the change d7346e614f4ec is introduced. In other words,
this diff reflects the changes that occurs in the DSDT table due to the change
d7346e614f4ec .

We added a new unit test for testing acpi hotplug on multifunction bridges in
q35 machines. Here, we update the DSDT table gloden master blob for this unit
test.
Following is the ASL diff between the original DSDT table and the modified DSDT
table due to the unit test:

if test can work without 'nodefaults', it would be better as it
introduces not related diff hunk in the following patch.
Other than that patch looks good to me.

yes that is a fair comment. I have sent a v3 with nodefaults removed. I
had to adjust the test a bit because we now have VGA and other devices
occupying certain slots.

BUG is quite old, since the time the function was actually written -
70e1ee59bb94 ("hw/pci: introduce bridge-only vendor-specific capability to
provide some hints to firmware")
I doubt in BE systems it ever worked.

Yes which is why I was confused as well since the test would not
introduce regression in the product!

Ok good. wanted to take a look at it with a clear mind in the morning but
since this is fixed, all is good.

This seems to break on s390 hosts for people. Likely an
endian-ness bug somewhere. Dropped for now - care tracking that down
and fixing so I can pick up the test again?

changelist:
v3: removed "nodefaults" from the command line and rebased the patchset.
v2: incorporated some of the feedbacks from Igor.
v1 : initial RFC patch.
This patchset adds a unit test to exercize acpi hotplug support for multifunction
bridges on q35 machines. This support was added with the commit:
d7346e614f4ec ("acpi: x86: pcihp: add support hotplug on multifunction bridges")
Ani Sinha (3):
tests/acpi/bios-tables-test: add and allow changes to a new q35 DSDT
