      gtk: don't leak the GtkBorder with VTE 0.36 · 6978dc4a
      由 Alberto Garcia 提交于 
      When gtk_widget_style_get() is used to get the "inner-border" style
property, it returns a copy of the GtkBorder which must be freed by
the caller.

This patch also fixes a warning about the unused 'padding' structure
with VTE 0.36.

      ui: sdl2: Release grab before opening console window · 56f289f3
      由 Cole Robinson 提交于 
      sdl 2.0.4 currently has a bug which causes our UI shortcuts to fire
rapidly in succession:

  https://bugzilla.libsdl.org/show_bug.cgi?id=3287

It's a toss up whether ctrl+alt+f or ctrl+alt+2 will fire an
odd or even number of times, thus determining whether the action
succeeds or fails.

Opening monitor/serial windows is doubly broken, since it will often
lock the UI trying to grab the pointer:

We can work around that hang by ungrabbing the pointer before launching
a new window. This roughly matches what our sdl1 code does

      ui/virtio-gpu: add and use qemu_create_displaysurface_pixman · ca58b45f
      由 Gerd Hoffmann 提交于 
      Add a the new qemu_create_displaysurface_pixman function, to create
a DisplaySurface backed by an existing pixman image.  In that case
there is no need to create a new pixman image pointing to the same
backing storage.  We can just use the existing image directly.

This does not only simplify things a bit, but most importantly it
gets the reference counting right, so the backing storage for the
pixman image wouldn't be released underneath us.

Use new function in virtio-gpu, where using it actually fixes
use-after-free crashes.

      qapi: Don't special-case simple union wrappers · 32bafa8f
      由 Eric Blake 提交于 
      Simple unions were carrying a special case that hid their 'data'
QMP member from the resulting C struct, via the hack method
QAPISchemaObjectTypeVariant.simple_union_type().  But by using
the work we started by unboxing flat union and alternate
branches, coupled with the ability to visit the members of an
implicit type, we can now expose the simple union's implicit
type in qapi-types.h:

| struct q_obj_ImageInfoSpecificQCow2_wrapper {
|     ImageInfoSpecificQCow2 *data;
| };
|
| struct q_obj_ImageInfoSpecificVmdk_wrapper {
|     ImageInfoSpecificVmdk *data;
| };
...
| struct ImageInfoSpecific {
|     ImageInfoSpecificKind type;
|     union { /* union tag is @type */
|         void *data;
|-        ImageInfoSpecificQCow2 *qcow2;
|-        ImageInfoSpecificVmdk *vmdk;
|+        q_obj_ImageInfoSpecificQCow2_wrapper qcow2;
|+        q_obj_ImageInfoSpecificVmdk_wrapper vmdk;
|     } u;
| };

Doing this removes asymmetry between QAPI's QMP side and its
C side (both sides now expose 'data'), and means that the
treatment of a simple union as sugar for a flat union is now
equivalent in both languages (previously the two approaches used
a different layer of dereferencing, where the simple union could
be converted to a flat union with equivalent C layout but
different {} on the wire, or to an equivalent QMP wire form
but with different C representation).  Using the implicit type
also lets us get rid of the simple_union_type() hack.

Of course, now all clients of simple unions have to adjust from
using su->u.member to using su->u.member.data; while this touches
a number of files in the tree, some earlier cleanup patches
helped minimize the change to the initialization of a temporary
variable rather than every single member access.  The generated
qapi-visit.c code is also affected by the layout change:

|@@ -7393,10 +7393,10 @@ void visit_type_ImageInfoSpecific_member
|     }
|     switch (obj->type) {
|     case IMAGE_INFO_SPECIFIC_KIND_QCOW2:

      input: linux evdev support · e0d2bd51
      由 Gerd Hoffmann 提交于 
      This patch adds support for reading input events directly from linux
evdev devices and forward them to the guest.  Unlike virtio-input-host
which simply passes on all events to the guest without looking at them
this will interpret the events and feed them into the qemu input
subsystem.

Therefore this is limited to what the qemu input subsystem and the
emulated input devices are able to handle.  Also there is no support for
absolute coordinates (tablet/touchscreen).  So we are talking here about
basic mouse and keyboard support.

The advantage is that it'll work without virtio-input drivers in the
guest, the events are delivered to the usual ps/2 or usb input devices
(depending on what the machine happens to have).  And for keyboards
qemu is able to switch the keyboard between guest and host on hotkey.
The hotkey is hard-coded for now (both control keys), initialy the
guest owns the keyboard.

Probably most useful when assigning vga devices with vfio and using a
physical monitor instead of vnc/spice/gtk as guest display.

Usage:  Add '-input-linux /dev/input/event<nr>' to the qemu command
line.  Note that udev has rules which populate /dev/input/by-{id,path}
with static names, which might be more convinient to use.

      qapi: Avoid use of 'data' member of QAPI unions · 10f75907
      由 Eric Blake 提交于 
      QAPI code generators currently create a 'void *data' member as
part of the anonymous union embedded in the C struct corresponding
to a QAPI union.  However, directly assigning to this member of
the union feels a bit fishy, when we can assign to another member
of the struct instead.

      ui: Shorten references into InputEvent · b5a1b443
      由 Eric Blake 提交于 
      An upcoming patch will alter how simple unions, like InputEvent, are
laid out, which will impact all lines of the form 'evt->u.XXX'
(expanding it to the longer 'evt->u.XXX.data').  For better
legibility in that patch, and less need for line wrapping, it's better
to use a temporary variable to reduce the effect of a layout change to
just the variable initializations, rather than every reference within
an InputEvent.

There was one instance in hid.c:hid_pointer_event() where the code
was referring to evt->u.rel inside the case label where evt->u.abs
is the correct name; thankfully, both members of the union have the
same type, so it happened to work, but it is now cleaner.
