[Qemu-devel] [PATCH for-3.2 v4 00/28] Generalize machine compatibility properties

[Marc-André Lureau]

Hi,

During "[PATCH v2 05/10] qom/globals: generalize
object_property_set_globals()" review, Eduardo suggested to rework the
GlobalProperty handling, so that -global is limited to QDev only and
we avoid mixing the machine compats and the user-provided -global
properties (instead of generalizing -global to various object kinds,
like I proposed in v2).

"qdev: do not mix compat props with global props" patch decouples a
bit user-provided -global from machine compat properties. This allows
to get rid of "user_provided" and "errp" fields in following patches.

Instead of explcitely calling object_apply_global_props() in the
various object post_init, I opted for creating a new TYPE_COMPAT_PROPS
interface. The interface approach gives a lot more flexibility on
which objects can have compat props. This requires some interface
improvments in "qom: teach interfaces to implement post-init".

A new compat property "x-use-canonical-path-for-ramblock-id" is added
to hostmem for legacy canonical path names, set to true for -file and
-memfd with qemu < 3.2.

(this series was initially titled "[PATCH v2 00/10] hostmem: use
object "id" for memory region name with >= 3.1", but its focus is more
in refactoring the global and compatilibity properties handling now)

v4:
- fix accel/machine compat props apply order inversion
- split "qdev: do not mix compat props with global props": replace
  using current_machine by new compat_props global, introduce
  SET_COMPAT() macro, use GPtrArray.
- add a comment about "qdev-props: call object_apply_global_props()"
  error reporting
- add "arm: replace instance_post_init()", to solve the post-init
  ordering issue
- add "hw/arm/virt: add virt-3.2 machine type" for completeness
- commit message improvements
- rebased, add r-b tags

v3:
- GlobalProperties improvements/cleanups
- drop generalizing the -global idea
- "replace" the set_globals flag with a TYPE_COMPAT_PROPS interface
- update hw/i386 machine version to 3.2
- add "qom: make interface types abstract" interface cleanup

v2:
- replace "qom/user-creatable: add a few helper macros" patch for a
  more optimized "qom: make user_creatable_complete() specific to
  UserCreatable"
- rename register_global_list() to register_global_properties()
- call object_property_set_globals() after post-init
- add and use a ObjectClass.set_globals flag, instead of dynamically
  check object class in object_property_set_globals()
- use object "id" in >= 3.1 instead of canonical path, add compat
  property "x-use-canonical-path-for-ramblock-id" in base hostmem
  class.
