Commit 261747f1 ("vl: Use MachineClass instead of global QEMUMachine
list") broke the ordering of the machine types in the user-visible output
of
qemu-system-XXXX -M \?
This occurred because registration was rebased from a manually maintained
linked list to GLib hash tables:
qemu_register_machine()
type_register()
type_register_internal()
type_table_add()
g_hash_table_insert()
and because the listing was rebased accordingly, from the traversal of the
list to the traversal of the hash table (rendered as an ad-hoc list):
machine_parse()
object_class_get_list(TYPE_MACHINE)
object_class_foreach()
g_hash_table_foreach()
The current order is a "random" one, for practical purposes, which is
annoying for users.
Introduce new members QEMUMachine.family and MachineClass.family, allowing
machine types to be "clustered". Introduce a comparator function that
establishes a total ordering between machine types, ordering machine types
in the same family next to each other. In machine_parse(), list the
supported machine types sorted with the comparator function.
The comparator function:
- sorts whole families before standalone machine types,
- sorts whole families between each other in alphabetically increasing
order,
- sorts machine types inside the same family in alphabetically decreasing
order,
- sorts standalone machine types between each other in alphabetically
increasing order.
After this patch, all machine types are considered standalone, and
accordingly, the output is alphabetically ascending. This will be refined
in the following patches.
