2010-01-20QMP: Fix asynchronous events deliveryLuiz Capitulino
Commit f039a563f200beee80cc10fd70b21ea396979dab introduces a regression as monitor_protocol_event() will return in the first user Monitor it finds in the QLIST_FOREACH() loop. The right thing to do is to only delivery an asynchronous event if the 'mon' is a QMP Monitor. The aforementioned commit was an early version, if it was applied to stable (it should) this one has to be applied there too.

2010-01-20virtio-serial: Use MSI vectors for port virtqueuesAmit Shah
This commit enables the use of MSI interrupts for virtqueue notifications for ports. We use nr_ports + 1 (for control channel) msi entries for the ports, as only the in_vq operations need an interrupt on the guest.

2010-01-20virtio-serial: Add a 'virtserialport' device for generic serial port supportAmit Shah
This commit adds a simple chardev-based serial port. Any data the guest sends is forwarded to the chardev and vice-versa. Sample uses for such a device can be obtaining info from the guest like the file systems used, apps installed, etc. for offline usage and logged-in users, clipboard copy-paste, etc. for online usage.

2010-01-20virtio-serial-bus: Add a port 'name' property for port discovery in guestsAmit Shah
The port 'id' or number is internal state between the guest kernel and our bus implementation. This is invocation-dependent and isn't part of the guest-host ABI. To correcly enumerate and map ports between the host and the guest, the 'name' property is used. Example: -device virtserialport,name=org.qemu.port.0 This invocation will get us a char device in the guest at: /dev/virtio-ports/org.qemu.port.0 which can be a symlink to /dev/vport0p3 This 'name' property is exposed by the guest kernel in a sysfs attribute: /sys/kernel/virtio-ports/vport0p3/name A simple udev script can pick up this name and create the symlink mentioned above.

2010-01-20virtio-serial-bus: Maintain guest and host port open/close stateAmit Shah
Via control channel messages, the guest can tell us whether a port got opened or closed. Similarly, we can also indicate to the guest of host port open/close events. Signed-off-by: Amit Shah <amit.shah@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-01-20virtio-console: qdev conversion, new virtio-serial-busAmit Shah
This commit converts the virtio-console device to create a new virtio-serial bus that can host console and generic serial ports. The file hosting this code is now called virtio-serial-bus.c. The virtio console is now a very simple qdev device that sits on the virtio-serial-bus and communicates between the bus and qemu's chardevs. This commit also includes a few changes to the virtio backing code for pci and s390 to spawn the virtio-serial bus. As a result of the qdev conversion, we get rid of a lot of legacy code. The old-style way of instantiating a virtio console using -virtioconsole ... is maintained, but the new, preferred way is to use -device virtio-serial -device virtconsole,chardev=... With this commit, multiple devices as well as multiple ports with a single device can be supported. For multiple ports support, each port gets an IO vq pair. Since the guest needs to know in advance how many vqs a particular device will need, we have to set this number as a property of the virtio-serial device and also as a config option. In addition, we also spawn a pair of control IO vqs. This is an internal channel meant for guest-host communication for things like port open/close, sending port properties over to the guest, etc. This commit is a part of a series of other commits to get the full implementation of multiport support. Future commits will add other support as well as ride on the savevm version that we bump up here. Signed-off-by: Amit Shah <amit.shah@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-01-20virtio: Remove duplicate macro definition for max. virtqueues, bump up the maxAmit Shah

2010-01-19QMP: Emit asynchronous events on all QMP monitorsAdam Litke
When using a control/QMP monitor in tandem with a regular monitor, asynchronous messages can get lost depending on the order of the QEMU program arguments. QEMU events issued by monitor_protocol_event() always go to cur_mon. If the user monitor was specified on the command line first (or it has ,default), the message will be directed to the user monitor (not the QMP monitor). Additionally, only one QMP session is currently able to receive async messages. To avoid this confusion, scan through the list of monitors and emit the message on each QMP monitor.

2010-01-19Fix QEMU_WARN_UNUSED_RESULTKevin Wolf
Since commit 747bbdf7 QEMU_WARN_UNUSED_RESULT is never defined as it is conditional on a define from config-host.h which is included only later. Include that file earlier to get the warnings back. Reactivating it unfortunately leads to some warnings about unused qdev_init results. These calls are changed to qdev_init_nofail to avoid build failures.

2010-01-19QMP: Introduce VNC_CONNECTED eventLuiz Capitulino
It's emitted when a VNC client connects to QEMU, client's information such as port and IP address are provided. Note that this event is emitted right when the connection is established. This means that it happens before authentication procedure and session initialization. Event example: { "event": "VNC_CONNECTED", "timestamp": { "seconds": 1262976601, "microseconds": 975795 }, "data": { "server": { "auth": "sasl", "family": "ipv4", "service": "5901", "host": "0.0.0.0" }, "client": { "family": "ipv4", "service": "58425", "host": "127.0.0.1" } } } Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-01-19VNC: Cache client info at connection timeLuiz Capitulino
When a disconnection happens the client's socket on QEMU side may become invalid, this way it won't be possible to query it to get client information, which is going to be needed by the future QMP VNC_DISCONNECTED event. To always have this information available we query the socket at connection time and cache the client info in struct VncState. Two function are introduced to perform this job. vnc_client_cache_addr() is called right when the connection is made, however the authentication information is not available at that moment so vnc_client_cache_auth() is called from protocol_client_init() to get auth info.

2010-01-19VNC: Rename client's 'username' keyLuiz Capitulino

2010-01-19VNC: Make 'auth' key mandatoryLuiz Capitulino
There is no reason to have it as optional and the code in the server and client gets slightly simpler if the key is mandatory. While there also do some cleanup on how the server info is collected.

2010-01-19VNC: Use 'enabled' key instead of 'status'Luiz Capitulino
Currently the 'status' key is a string whose value can be "disabled" or "enabled", change it to the QMP's standard 'enabled' key, which is a bool.
