Upstream commit: d7741743f4f3d2683d1bb6938f88dc0167c21afa
|
|
|
|
Making some global properties optional will let us simplify
|
|
compat code when a given property works on most (but not all)
|
|
subclasses of a given type.
|
|
|
|
Device types will be able to opt out from optional compat
|
|
properties by simply not registering those properties.
|
|
|
|
Backport conflict notes:
|
|
Patching qdev_prop_set_globals(), because our downstream tree
|
|
still doesn't have object_apply_global_props() from commit
|
|
ea9ce8934c5d ("hw: apply accel compat properties without
|
|
touching globals")
