Hi
At the end, Daved asked for a couple of things on previous series.
[v2]
- Ensure that we start in NONE even after failed/canceled migration
- move printf's to traces
- make sure that we can migrate the new states like guest-panicked
(not sure if it is a good idea to enable migrate a guest-panicked, but
it is not this series the place to forbid it)
- address all comments from Dave and Eric.
Please, review.
[v1]
As the beggining of both series have been accepted, I merged both here.
Changes:
- answered all comments on list and applied suggested changes
- Use migrate_set_state() consistently
- we were misusing atomic_cmpxchg(), it didn't matter until now because
we were missing only traces, but it showed with events missing.
- Reorganized how the migration events are generated, now only on
migrate_set_state.
Please review.
Juan Quintela (12):
runstate: Add runstate store
runstate: migration allows more transitions now
migration: create new section to store global state
global_state: Make section optional
vmstate: Create optional sections
migration: Add configuration section
migration: Use cmpxchg correctly
migration: ensure we start in NONE state
migration: Use always helper to set state
migration: No need to call trace_migrate_set_state()
migration: create migration event
migration: Add migration events on target side
