I will check.

Can you confirm that you are talking about this test:
  https://elixir.bootlin.com/linux/v6.12-rc6/source/drivers/of/unittest.c#L4188

The test needs QEMU with a specific setup and I found this entry point:
  https://lore.kernel.org/all/fa208013-7bf8-80fc-2732-814f380cebf9@amd.com/

Do you have an "official" QEMU setup on your side to run the test or any
other pointers related to the QEMU command/setup you use?

Best regards,
Hervé
