Hi,
I'm trying to find my way through yaml_to_mux, and looking for
recommendations on how to represent QEMU features in the Avocado
multiplexer tree.
Problem statement
-----------------
Assuming I have the following QEMU binaries:
qemu-system-x86_64:
supports machine-types: pc, q35, none
qemu-system-ppc64:
supports machine-types: pseries, prep, none
I want to run the following test cases with a few variants:
Test 1:
Will test all machine-types on all QEMU binaries
Test 2:
Will test all machine-types except "none"
In other words, I want to generate the following test variants:
For Test 1:
qemu_bin=qemu-system-x86_64, machine=pc
qemu_bin=qemu-system-x86_64, machine=q35
qemu_bin=qemu-system-x86_64, machine=none
qemu_bin=qemu-system-ppc64, machine=pseries
qemu_bin=qemu-system-ppc64, machine=prep
qemu_bin=qemu-system-ppc64, machine=none
For Test 2:
qemu_bin=qemu-system-x86_64, machine=pc
qemu_bin=qemu-system-x86_64, machine=q35
qemu_bin=qemu-system-ppc64, machine=pseries
qemu_bin=qemu-system-ppc64, machine=prep
The solution I have tried
-------------------------
I have generated the following YAML file (variants.yaml):
arch: !mux
x86_64:
qemu_bin: qemu-system-x86_64
machine: !mux
none: {machine: none}
pc: {machine: pc}
q35: {machine: q35}
ppc64:
qemu_bin: qemu-system-ppc64
machine: !mux
none: {machine: none}
prep: {machine: prep}
pseries: {machine: pseries}
Then I thought I could do this on a test2.yaml file:
!include : 'variants.yaml'
!filter-out : /machine/none
But this won't work, because "-machine none" is represented by a
different path on each architecture (/arch/x86_64/machine/none vs
/arch/ppc64/machine/none).
Is there a way to place the machine-type name always under
"/machine" (not /arch/.../machine), but generate a different set
of values for /machine for each QEMU binary?
Maybe I'm misguided and is there a better way to encode the
information above?
