[Qemu-devel] [PATCH qemu v2] qom: Document qom/device-list-properties implementation specific

[Alexey Kardashevskiy <aik@ozlabs.ru>]

The recently introduced qom-list-properties QMP command raised
a question what properties it (and its cousin - device-list-properties)
can possibly print - only those defined by DeviceClass::props
or dynamically created in TypeInfo::instance_init() so properties created
elsewhere won't show up and this behaviour might confuse the user.
For example, PIIX4 does that from piix4_pm_realize():

hw/acpi/piix4.c|477| object_property_add_uint8_ptr(OBJECT(s),
ACPI_PM_PROP_ACPI_ENABLE_CMD,

This adds a note to the command descriptions about the limitation.
