Yes, this is an improvement over the current code. But it doesn't move in the direction we (or better Anthony) originally had for events in the QAPI. Basically, *iirc*, the idea was to have an event type, so that we could declare events as: { 'event': 'BLOCK_IO_ERROR', 'data': { 'device': 'str', 'operation': 'str', 'action': 'str' } } (Note that keys 'operation' and 'action' should be enums) Then the QAPI could generate C functions to register and de-register from an event. This way C code could benefit from events too, and we could also allow QMP clients to register/de-register to/from events. Maybe we could apply this series as a first step, but I can't tell if later on we'll regret it due to compatibility issues or if we'll realize it was unneeded churn. I am coding a version to fullly support event in qmp schema, will send it soon.

Re: [Qemu-devel] [PATCH 0/6] qapi: generate event defines automatically
Hi, Markus I am coding V2 which support event in qapi-schema, and just remember it is on your TODO list. Is it OK to let me implement it instead as V2?
