ACPI PCI hotplug is now turned on by default so we need to change the
existing tests to keep it off. However, even setting the ACPI PCI
hotplug off in the existing tests, there will be changes in the ACPI
tables because the _OSC method was modified, hence in the next patch of
this series the blobs are updated accordingly.

it would be better to test whatever default we end up with.
(like x86)

hmm maybe there is a confusion here, Igor. We are actually planning what you
said. This patch and the other two in this series related to the 
bios-tables-test
(i.e., patches 8/25 and 10/25) are for actually making the current (legacy) 
test pass,
since the new default as per this series will be acpi-pcihp=on. That's why here 
we're
adapting the current test here to have acpi-pcihp=off.

The new test that will test for acpi-pcihp=on (the new default) is not in this 
series
and we decided to merge it separate. It's in the patch 4/5 and 5/5 of the 
follow series:

https://mail.gnu.org/archive/html/qemu-devel/2025-05/msg05828.html 4/5
https://mail.gnu.org/archive/html/qemu-devel/2025-05/msg05827.html 5/5


Cheers,
Gustavo

[Eric] also added acpi-pcihp=off to test_acpi_aarch64_virt_tcg_numamem
