[Qemu-devel] [PATCH 00/10] Fix machine class names to use the "-machine" suffix

[Qemu-devel] [PATCH 00/10] Fix machine class names to use the "-machine" suffix

[Eduardo Habkost]

The machine class names in QEMU are not consistent today. Some of them use the
"-machine" suffix, but some use completely different naming conventions. This
makes it difficult to implement machine class lookup without iterating through
the whole list of machine classes.

This series changes all machines to use "<machine name>-machine" as the class
name, so we can simply use object_class_by_name() in the future to lookup
machine classes. (This was not done yet because it will also require some
changes in the way aliases are handled.)

[Qemu-devel] [PATCH 01/10] machine: MACHINE_TYPE_NAME macro

[Eduardo Habkost]

The macro will be useful to ensure the machine class names follow the
right format to make machine class lookup by class name work correctly.

[Eduardo Habkost]

The MachineClass::name field won't be ever be used on TYPE_VEXPRESS, as
it is an abstract class and the machine class lookup code explicitly
skips abstract classes. We can remove it to make the code simpler.

I'm also happy to take this through by spapr-next tree if that's
useful to do.

[Qemu-devel] [PATCH 06/10] s390-virtio: Rename machine class name to use MACHINE_TYPE_NAME

machine class using the MACHINE_TYPE_NAME macro.

If it's just a single line addition I can edit that when applying.
Anything else in need of changes?

I have just double-checked that there are no other machine classes that
need to be renamed. For reference, this is the patch that needs to be
squashed into this one:

[Qemu-devel] [PATCH 08/10] mac99: Use MACHINE_TYPE_NAME to encode class name

[Eduardo Habkost]

It will result in exactly the same class name, but it will make the code
consistent with the other classes.

[Qemu-devel] [PATCH 09/10] machine: Ensure all TYPE_MACHINE subclasses have the right suffix

[Eduardo Habkost]

Now that all non-abstract TYPE_MACHINE subclasses have the -machine
suffix, add an assert to ensure this will be always true.

[Qemu-devel] [PATCH 10/10] machine: Set MachineClass::name automatically

[Eduardo Habkost]

Now all TYPE_MACHINE subclasses use MACHINE_TYPE_NAME to generate the
class name. So instead of requiring each subclass to set
MachineClass::name manually, we can now set it automatically at the
TYPE_MACHINE class_base_init() function.

Nice!

Please forget the possible stupid question, but what happens with
*all* other machine types? Why don't we have to remove the "name"
assignment from the other machine types too?

Unless I made a mistake and missed something when grepping the code, all
machine-types were changed. Most of them use qemu_register_machine()
(which uses qemu_machine_class_init(), changed above).

The s390-virtio-ccw machines are missing from this patch. The following
patch can be squashed into this one.

If a more formal follow-up patch or v2 patch is preferred, please let me

I've played around with the s390 machines a bit and it seems to do the
right thing using the same commandlines as before.

One question: info qom-tree shows the new machine class names - is
there anybody (other than a human looking at it) making use of that
information?

I don't believe anybody is using it. It would be possible to use the
class name for something useful if machines were user-creatable objects,
but they aren't.

Long-term I would prefer a separate machine maintainer (Marcel?) to
handle this, but as discussed in Seattle, I'm applying this series to
qom-next and will look at the follow-up series next.

Hi Andreas,

I can be the machine maintainer, sure.
I should start maintaining contribution anyway, this could be a start.
