From 961c47bb8bacc9ae21c0760fa6e2594156299dd7 Mon Sep 17 00:00:00 2001 From: Alexey Kardashevskiy Date: Fri, 2 Mar 2018 00:09:39 +1100 Subject: qmp: Add qom-list-properties to list QOM object properties There is already 'device-list-properties' which does most of the job, however it does not handle everything returned by qom-list-types such as machines as they inherit directly from TYPE_OBJECT and not TYPE_DEVICE. It does not handle abstract classes either. This adds a new qom-list-properties command which prints properties of a specific class and its instance. It is pretty much a simplified copy of the device-list-properties handler. Since it creates an object instance, device properties should appear in the output as they are copied to QOM properties at the instance_init hook. This adds a object_class_property_iter_init() helper to allow class properties enumeration uses it in the new QMP command to allow properties listing for abstract classes.
