From bc2f4fcb1dd1a66ede126593fa091c23a94e3ab8 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Fri, 12 Mar 2021 12:35:46 -0500 Subject: qom: move user_creatable_add_opts logic to vl.c and QAPIfy it Emulators are currently using OptsVisitor (via user_creatable_add_opts) to parse the -object command line option. This has one extra feature, compared to keyval, which is automatic conversion of integers to lists as well as support for lists as repeated options: -object memory-backend-ram,id=pc.ram,size=1048576000,host-nodes=0,policy=bind So we cannot replace OptsVisitor with keyval right now. Still, this patch moves the user_creatable_add_opts logic to vl.c since it is not needed anywhere else, and makes it go through user_creatable_add_qapi. In order to minimize code changes, the predicate still takes a string. This can be changed later to use the ObjectType QAPI enum directly.
