Today, QOM properties carry a free-form "type" string ("bool", "uint32", "OnOffAuto", ..) that has no formal link to the QAPI schema exposed by query-qmp-schema. Management tools must maintain ad-hoc mappings or rely on naming conventions to figure out how to interpret property values. This series adds: - A new QAPITypeInfo struct that pairs a property with its QAPI schema type name, enum lookup table, and list-element type. - A QAPI code generator (qapi-type-infos) that emits a QAPITypeInfo instance for every schema-defined type, including the mapping between internal C names and the schema name visible to clients. - A "qapi-type" field in the ObjectPropertyInfo and ObjectPropertyValue QMP structs, populated from the QAPITypeInfo when present giving clients a cross-reference into query-qmp-schema output. - Conversion of all PropertyInfo definitions from the old .type/.enum_table strings to the new .qapi_type pointer. - Replacement of the generic qdev_prop_array with typed per-element array PropertyInfos, removing the arrayinfo/arrayfieldsize indirection from struct Property. - Removal of the deprecated PropertyInfo.type and .enum_table fields, and of the old object_property_add_enum/add_tm APIs. Along the way, a few pre-existing type mismatches in property definitions are fixed, the "struct tm" RTC property is replaced with a proper QAPI StructTm type etc. Introducing more specific types or a "typedef" to QAPI could help provide better associated type informations than plain "str" in many cases, for example. Comments welcome! Signed-off-by: Marc-André Lureau --- Changes in v3: - QAPI analysis redesign (replacing the old "expose name map" from introspect) - all non-implicit QAPI types are now introspectable, including QOM-only types - QAPITypeInfo.schema_name -> masked_name - exposes integer signedness and width through query-qmp-schema - various extra property fixes - rebase, some patch split or merge - Link to v2: https://lore.kernel.org/qemu-devel/20260616-qom-qapi-v2-0-cc9396b9c18c@redhat.com Changes in v2: - Added kernel-doc documentation for the QAPITypeInfo struct fields. - Dropped "qom: drop free-form property typename registration", it's still needed for array of links to provide useful type names. - Added qdev_prop_link_list for array-of-links properties, with a create function that generates "linkList" type names matching the existing "link" convention. - qdev_prop_link now uses &str_type_info instead of "link" (the full "link" type name is set at property-add time) - Simplified DEFINE_PROP_LINK_ARRAY to use qdev_prop_link_list, dropping the now-unnecessary _arraytype parameter. - rebased - Link to v1: https://lore.kernel.org/qemu-devel/20260510-qom-qapi-v1-0-48ba6a1a1fa5@redhat.com To: qemu-devel@nongnu.org Cc: Markus Armbruster Cc: Michael Roth Cc: Pierrick Bouvier Cc: Paolo Bonzini Cc: Marc-André Lureau Cc: "Daniel P.
