[PATCH v3 0/5] Add 'q35' machine type to hotplug tests

[PATCH v3 0/5] Add 'q35' machine type to hotplug tests

[Michael Labiuk via]

Add pci bridge setting to run hotplug tests on q35 machine type.
Hotplug tests was bounded to 'pc' machine type by commit 7b172333f1b

Michael Labiuk (5):
  tests/x86: Add subtest with 'q35' machine type to device-plug-test
  tests/x86: Add 'q35' machine type to ivshmem-test
  tests/x86: Add 'q35' machine type to drive_del-test
  tests/x86: Add 'q35' machine type to hotplug hd-geo-test
  tests/x86: Add 'q35' machine type to override-tests in hd-geo-test

this patch mixes non-functional changes - process_device_remove() helper
introduction and functional ones - new test cases added. It is mandatory
to have such stuff separated into different patches.

hmmm, why do we need this helper if it is not used anywhere in next

it is also unclear to me why don't we do 'device_del' for other archs.
May be this is to be clarified in the patch description or worth
additional patch.

device_del() used instead of qpci_unplug_acpi_device_test() because
unplug_acpi is supported for x86 i440fx only.

Also "DEVICE_DELETED" will not being emitted for 'q35' pci-e device 
without support from guest side.

These are the reasons for custom unplugging function.
