New device, has never been released, so we can still improve things without worrying about compatibility. Naming is a mess. The code calls the device driver CirMemCharDriver, the public API calls it "memory", "memchardev", or "memchar", and the special commands are named like "memchar-FOO". "memory" is a particularly unfortunate choice, because there's another character device driver called MemoryDriver. Moreover, the device's distinctive property is that it's a ring buffer, not that's in memory. Therefore: * Rename CirMemCharDriver to RingBufCharDriver, and call the thing a "ringbuf" in the API. * Rename QMP and HMP commands from memchar-FOO to ringbuf-FOO. * Rename device parameter from maxcapacity to size (simple words are good for you). * Clearly mark the parameter as optional in documentation. * Fix error reporting so that chardev-add reports to current monitor, not stderr. * Replace cirmem in C identifiers by ringbuf. * Rework documentation. Document the impact of our crappy UTF-8 handling on reading. * QMP examples that even work. I could split this up into multiple commits, but they'd change the same documentation lines multiple times. Not worth it. Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
