Here I need to add a test that creates a vfio-pci device and numa
nodes and link using the acpi-generic-initiator object. One thing
here is that the -device vfio-pci needs a host=<bdf> argument. I
probably cannot provide the device bdf from my local setup. So
I am not sure how can I add this test to tests/qtest/bios-tables-test.c.
FYI, the following is a sample args we use for the
acpi-generic-initiator object.
-numa node,nodeid=2
-device vfio-pci-nohotplug,bus=pcie.0,addr=04.0,rombar=0,id=dev0 \
-object acpi-generic-initiator,id=gi0,pci-dev=dev0,node=2 \
Moreover based on a quick grep, I don't see any other test that
have -device vfio-pci argument.
Jonathan, Alex, do you know how we may add tests that is dependent
on the vfio-pci device?
There are none.
This would require a host device always available for passthrough and
there is no simple solution for this problem. Such tests would need to
run in a nested environment under avocado: a pc/virt machine with an
igb device and use the PF and/or VFs to check device assignment in a
nested guests.
PPC just introduced new tests to check nested guest support on two
different HV implementations. If you have time, please take a look
at tests/avocado/ppc_hv_tests.py for the framework.
I will try to propose a new test when I am done with the reviews,
not before 9.0 soft freeze though.
Thanks,
C.
