2014-06-23qapi: adjust existing definesWenchao Xia2-4/+2
In order to let event defines use existing types later, instead of redefine new ones, some old type defines for spice and vnc are changed, and BlockErrorAction is moved from block.h to qapi schema. Note that BlockErrorAction is not merged with BlockdevOnError. At this point, VncInfo is not made a child of VncBasicInfo, because VncBasicInfo has mandatory fields where VncInfo makes them optional.

2014-06-23fpu: softfloat: drop INLINE macroLuiz Capitulino1-50/+49
This commit expands all uses of the INLINE macro and drop it. The reason for this is to avoid clashes with external libraries with bad name conventions and also because renaming keywords is not a good practice.

2014-06-23vl: allow other threads to do qemu_system_vmstop_requestPaolo Bonzini1-0/+1
There patch protects vmstop_requested with a lock and introduces qemu_system_vmstop_request_prepare. Together with the new call to qemu_vmstop_requested in vm_start, qemu_system_vmstop_request_prepare avoids a race where the VM could remain stopped even though the iostatus of a block device has already been set (for example). qemu_system_vmstop_request_prepare however also lets the caller thread delay observation of the state change until it has itself communicated that change to the user. This delay avoids any possibility of a wrong reordering of the BLOCK_IO_ERROR event and the subsequent STOP event.

2014-06-19virtio-net: announce self by guestJason Wang2-0/+22
It's hard to track all mac addresses and their configurations (e.g vlan or ipv6) in qemu. Without this information, it's impossible to build proper garp packet after migration. The only possible solution to this is let guest (who knows all configurations) to do this. So, this patch introduces a new readonly config status bit of virtio-net, VIRTIO_NET_S_ANNOUNCE which is used to notify guest to announce presence of its link through config update interrupt.When guest has done the announcement, it should ack the notification through VIRTIO_NET_CTRL_ANNOUNCE_ACK cmd. This feature is negotiated by a new feature bit VIRTIO_NET_F_ANNOUNCE (which has already been supported by Linux guest). During load, a counter of announcing rounds is set so that after the vm is running it can trigger rounds of config interrupts to notify the guest to build and send the correct garps.

2014-06-19migration: introduce self_announce_delay()Jason Wang1-0/+8
This patch introduces self_announce_delay() to calculate the delay for the next announce round. This could be used by other device e.g virtio-net who wants to do announcing by itself.
