2013-02-22block: implement BDRV_O_UNMAPPaolo Bonzini3-2/+36
It is better to present homogeneous hardware independent of the storage technology that is chosen on the host, hence we make discard a host parameter; the user can choose whether to pass it down to the image format and protocol, or to ignore it. Using DISCARD with filesystems can cause very severe fragmentation, so it is left default-off for now. This can change later when we implement the "anchor" operation for efficient management of preallocated files. There is still one choice to make: whether DISCARD has an effect on the dirty bitmap or not. I chose yes, though there is a disadvantage: if the guest is buggy and issues discards for data that is in use, there will be no way to migrate storage for that guest without downgrading the machine type to an older one.

2013-02-22block: use Error in do_check_io_limits()Stefan Hajnoczi1-6/+8
The do_check_io_limits() function returns false when I/O limits are invalid but it doesn't set an Error to indicate why. The two do_check_io_limits() callers duplicate error reporting. Solve this by passing an Error pointer into do_check_io_limits(). Note that the two callers report slightly different errors: drive_init() prints a custom error message while qmp_block_set_io_throttle() does error_set(errp, QERR_INVALID_PARAMETER_COMBINATION). QERR_INVALID_PARAMETER_COMBINATION is a generic error, see include/qapi/qmp/qerror.h: #define QERR_INVALID_PARAMETER_COMBINATION \ ERROR_CLASS_GENERIC_ERROR, "Invalid parameter combination" Since it is generic we are not obliged to keep this error. Switch to the custom error message which contains more information. This patch prepares for adding additional checks with their own error messages to do_check_io_limits(). The next patch adds a new check. Reviewed-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

2013-02-21gtk: add support for screen scaling and full screen (v5)Anthony Liguori1-17/+237
Basic menu items to enter full screen mode and zoom in/out. Unlike SDL, we don't allow arbitrary scaling based on window resizing. The current behavior with SDL causes a lot of problems for me. Sometimes I accidentally resize the window a tiny bit while trying to move it (Ubuntu's 1-pixel window decorations don't help here). After that, scaling is now active and if the screen changes size again, badness ensues since the aspect ratio is skewed. Allowing zooming by 25% in and out should cover most use cases. We can add a more flexible scaling later but for now, I think this is a more friendly behavior.

2013-02-21gtk: add support for input grabbing (v2)Anthony Liguori1-5/+151
There is a small deviation from SDL's behavior here. Instead of Ctrl+Alt triggering grab, we now use Ctrl-Alt-g to trigger grab. GTK will not accept Ctrl+Alt as an accelerator since it just consists of modifiers. Having grab as a proper accelerator is important as it allows a user to override the accelerator for accessibility purposes. We also are not automatically grabbing on left-click. Besides the inability to tie mouse clicks to an accelerator, I think this behavior is hard to discover and since it only happens depending on the guest state, it can lead to confusing behavior. This can be changed in the future if there's a strong resistence to dropping left-click-to-grab, but I think we're better off dropping it.

2013-02-21ui: add basic GTK gui (v5)Anthony Liguori5-0/+615
This is minimalistic and just contains the basic widget infrastructure. The GUI consists of a menu and a GtkNotebook. To start with, the notebook has its tabs hidden which provides a UI that looks very similar to SDL with the exception of the menu bar. The menu bar allows a user to toggle the visibility of the tabs. Cairo is used for rendering. I used gtk-vnc as a reference. gtk-vnc solves the same basic problems as QEMU since it was originally written as a remote display for QEMU. So for the most part, the approach to rendering and keyboard handling should be pretty solid for GTK.

2013-02-21qom/object.c: Allow itf cast with num_itfs = 0Peter Crosthwaite1-1/+2
num_interfaces only tells you how many interfaces the concrete child class has (as defined in the TypeInfo). This means if you have a child class which defines no interfaces of its own, but its parent has interfaces you cannot cast to those parent interfaces. Fixed changing the guard to check the class->interfaces list instead (which is a complete flattened list of implemented interfaces).

2013-02-21qom/object.c: Reset interface list on inheritancePeter Crosthwaite1-0/+1
The QOM framework will attempt the recreate a classes interface list from scratch for each class. This means that a child class should zero out the list of interfaces when cloned from the parent class. Currently the list is memcpy()d from the parent to the child. As the interface list is just a pointer to a list, this means the parent and child will share the same list of interfaces. When the child inits, it will append its own interfaces to the parents list. This is incorrect as the parent should not pick up its childs interfaces. This actually causes an infinite loop at class init time, as the child will iterate through the parent interface list adding each itf to its own list(in type_initialize()). As the list is (erroneously) shared, the new interface instances for the child are appended to the parent, and the iterator never hits the tail and loops forever.

2013-02-21vga: fix byteswapping.Gerd Hoffmann6-16/+22
In case host and guest endianness differ the vga code first creates a shared surface (using qemu_create_displaysurface_from), then goes patch the surface format to indicate that the bytes must be swapped. The switch to pixman broke that hack as the format patching isn't propagated into the pixman image, so ui code using the pixman image directly (such as vnc) uses the wrong format. Fix that by adding a byteswap parameter to qemu_create_displaysurface_from, so we'll use the correct format when creating the surface (and the pixman image) and don't have to patch the format afterwards.

2013-02-21slirp: switch to GPollFDStefan Hajnoczi7-74/+87
Slirp uses rfds/wfds/xfds more extensively than other QEMU components. The rarely-used out-of-band TCP data feature is used. That means we need the full table of select(2) to g_poll(3) events: rfds -> G_IO_IN | G_IO_HUP | G_IO_ERR wfds -> G_IO_OUT | G_IO_ERR xfds -> G_IO_PRI I came up with this table by looking at Linux fs/select.c which maps select(2) to poll(2) internally. Another detail to watch out for are the global variables that reference rfds/wfds/xfds during slirp_select_poll(). sofcantrcvmore() and sofcantsendmore() use these globals to clear fd_set bits. When sofcantrcvmore() is called, the wfds bit is cleared so that the write handler will no longer be run for this iteration of the event loop. This actually seems buggy to me since TCP connections can be half-closed and we'd still want to handle data in half-duplex fashion. I think the real intention is to avoid running the read/write handler when the socket has been fully closed. This is indicated with the SS_NOFDREF state bit so we now check for it before invoking the TCP write handler. Note that UDP/ICMP code paths don't care because they are connectionless. Note that slirp/ has a lot of tabs and sometimes mixed tabs with spaces. I followed the style of the surrounding code.

2013-02-21main-loop: switch to g_poll() on POSIX hostsStefan Hajnoczi1-8/+129
Use g_poll(3) instead of select(2). Well, this is kind of a cheat. It's true that we're now using g_poll(3) on POSIX hosts but the *_fill() and *_poll() functions are still using rfds/wfds/xfds. We've set the scene to start converting *_fill() and *_poll() functions step-by-step until no more rfds/wfds/xfds users remain. Then we'll drop the temporary gpollfds_from_select() and gpollfds_to_select() functions and be left with native g_poll(2). On Windows things are a little crazy: convert from rfds/wfds/xfds to GPollFDs, back to rfds/wfds/xfds, call select(2), rfds/wfds/xfds back to GPollFDs, and finally back to rfds/wfds/xfds again. This is only temporary and keeps the Windows build working through the following patches. We'll drop this excessive conversion later and be left with a single GPollFDs -> select(2) -> GPollFDs sequence that allows Windows to use select(2) while the rest of QEMU only knows about GPollFD.
