2012-06-19Add PIIX4 properties to control PM system states.Gleb Natapov
This patch adds two things. First it allows QEMU to distinguish between regular powerdown and S4 powerdown. Later separate QMP notification will be added for S4 powerdown. Second it allows S3/S4 states to be disabled from QEMU command line. Some guests known to be broken with regards to power management, but allow to use it anyway. Using new properties management will be able to disable S3/S4 for such guests. Supported system state are passed to a firmware using new fw_cfg file. The file contains 6 byte array. Each byte represents one system state. If byte at offset X has its MSB set it means that system state X is supported and to enter it guest should use the value from lowest 3 bits.

2012-06-18qdev: Convert busses to QEMU Object ModelAnthony Liguori
This is far less interesting than it sounds. We simply add an Object to each BusState and then register the types appropriately. Most of the interesting refactoring will follow in the next patches. Since we're changing fundamental type names (BusInfo -> BusClass), it all needs to convert at once. Fortunately, not a lot of code is affected.

2012-06-18qdev: Clean up global propertiesPaolo Bonzini

2012-06-18qdev: Move bus properties to abstract superclassesPaolo Bonzini
In qdev, each bus in practice identified an abstract superclass, but this was mostly hidden. In QOM, instead, these abstract classes are explicit so we can move bus properties there. All bus property walks are removed, and all device property walks are changed to look along the class hierarchy instead. We would have duplicates if class A defines some properties and its subclass B does not define any, because class_b->props will be left equal to class_a->props. The solution here is to reintroduce the class_base_init TypeInfo callback, that was present in one of the early QOM versions but removed (on my request...) before committing. This breaks global bus properties, an obscure feature when used with the command-line which is actually useful and used when used by backwards-compatible machine types. So this patch also adjusts the global bus properties in hw/pc_piix.c to refer to the abstract class. Globals and other properties must be modified in the same patch to avoid complications related to initialization ordering.

2012-06-15Add rate limiting of RTC_CHANGE, BALLOON_CHANGE & WATCHDOG eventsDaniel P. Berrange
Allow certain event types to be rate limited to avoid flooding monitor clients. The monitor_protocol_event() method is changed such that instead of immediately emitting the event to Monitor instances, it will call a new monitor_protocol_event_queue() method. This will check to see if the rate limit for the event has been exceeded, and if so schedule a timer to wakeup at the end of the rate limit period. If further events arrive before the timer fires, the previously queued event will be discarded in favour of the new event. The event will eventually be emitted when the timer fires. This logic is applied to RTC_CHANGE, BALLOON_CHANGE & WATCHDOG events, since the data associated with these events is stateless * monitor.c: Add support for rate limiting * monitor.h: Define monitor_global_init for one-time setup tasks * vl.c: Invoke monitor_global_init * trace-events: Add hooks for monitor event tracing Signed-off-by: Daniel P.

2012-06-15Add event notification for guest balloon changesDaniel P. Berrange
After setting a balloon target value, applications have to continually poll 'query-balloon' to determine whether the guest has reacted to this request. The virtio-balloon backend knows exactly when the guest has reacted though, and thus it is possible to emit a JSON event to tell the mgmt application whenever the guest balloon changes. This introduces a new 'qemu_balloon_changed()' API which is to be called by balloon driver backends, whenever they have a change in balloon value. This takes the 'actual' balloon value, as would be found in the BalloonInfo struct. The qemu_balloon_change API emits a JSON monitor event which looks like: {"timestamp": {"seconds": 1337162462, "microseconds": 814521}, "event": "BALLOON_CHANGE", "data": {"actual": 944766976}} * balloon.c, balloon.h: Introduce qemu_balloon_changed() for emitting balloon change events on the monitor * hw/virtio-balloon.c: Invoke qemu_balloon_changed() whenever the guest changes the balloon actual value * monitor.c, monitor.h: Define QEVENT_BALLOON_CHANGE Signed-off-by: Daniel P.

2012-06-15xen: Don't peek behind the BlockDriverState abstractionMarkus Armbruster
