Hi, This has long been on my TODO list. I wanted to put this forward since Gerd has a chardev hotplug series. I think there are a few good reasons to go the QOM route here. Most notably:
1) the conversion cleans up all of the printfs into proper error messages 2) it becomes possible to introspect available character device types 3) it becomes possible (albeit a little awkward) to programmatically query options for a type There are quite a few things missing from this RFC although I think it can all be done incrementally. The continued items are: A) Replace chardev properties in devices with links B) Finish converting all usage of QemuOpts into proper properties C) Use class methods instead of function pointers in objects D) General cleanups I think the main decision point here is whether we introduce a separate chardev_add/chardev_del command or just use the qom-create command that has been posted previously. Please note, a few of these patches have long lines from a combination of code motion and automated conversion via macros.
