      input: Convert to new qapi union layout · 568c73a4
      由 Eric Blake 提交于 
      We have two issues with our qapi union layout:
1) Even though the QMP wire format spells the tag 'type', the
C code spells it 'kind', requiring some hacks in the generator.
2) The C struct uses an anonymous union, which places all tag
values in the same namespace as all non-variant members. This
leads to spurious collisions if a tag value matches a non-variant
member's name.

Make the conversion to the new layout for input-related code.

      ui/console: remove dpy_gfx_update_dirty · 42af3e3a
      由 Paolo Bonzini 提交于 
      dpy_gfx_update_dirty expects DIRTY_MEMORY_VGA logging to be always on,
but that will not be the case soon.  Because it computes the memory
region on the fly for every update (with memory_region_find), it cannot
enable/disable logging by itself.

We could always treat updates as invalidations if dirty logging is
not enabled, assuming that the board will enable logging on the
RAM region that includes the framebuffer.

However, the function is unused, so just drop it.

      console: add graphic_console_set_hwops · 1c1f9498
      由 Gerd Hoffmann 提交于 
      Add a function to allow display emulations to switch the hwops
function pointers.  This is useful for devices which have two
completely different operation modes.  Typical case is the vga
compatibility mode vs. native mode in qxl and the upcoming
virtio-vga device.

      console: rework text terminal cursor logic · aea7947c
      由 Gerd Hoffmann 提交于 
      Have a global timer.  Update all visible terminal windows syncronously.
Right now this can be the active_console only, but that will change
soon.  The global timer will disable itself if not needed, so we only
have to care start it if needed.  Which might be at console switch time
or when a new displaychangelistener is registered.

      console: nicer initial screen · 521a580d
      由 Gerd Hoffmann 提交于 
      Now that we have a function to create a fancy DisplaySurface with a
message for the user, to handle non-existing graphics hardware, we
can make it more generic and use it for other things too.

This patch adds a text line to the in initial DisplaySurface, notifying
the user that the display isn't initialized yet by the guest.

You can see this in action when starting qemu with '-S'.  Also when
booting ovmf in qemu (which needs a few moments to initialize itself
before it initializes the vga).

      console: Abort on property access errors · afff2b15
      由 Kirill Batuzov 提交于 
      All defined properties of QemuConsole are mandatory and no access to them
should fail. Nevertheless not checking returned errors is bad because in case
of unexpected failure it will hide the bug and cause a memory leak.

Abort in case of unexpected property access errors. This change exposed a bug
where an attempt was made to write to a read-only property "head".

Set "head" property's value at creation time and do not attempt to change it
later. This fixes the bug mentioned above.

      qom: Add check() argument to object_property_add_link() · 39f72ef9
      由 Stefan Hajnoczi 提交于 
      There are currently three types of object_property_add_link() callers:

1. The link property may be set at any time.
2. The link property of a DeviceState instance may only be set before
   realize.
3. The link property may never be set, it is read-only.

Something similar can already be achieved with
object_property_add_str()'s set() argument.  Follow its example and add
a check() argument to object_property_add_link().

Also provide default check() functions for case #1 and #2.  Case #3 is
covered by passing a NULL function pointer.

      qom: Make QOM link property unref optional · 9561fda8
      由 Stefan Hajnoczi 提交于 
      Some object_property_add_link() callers expect property deletion to
unref the link property object.  Other callers expect to manage the
refcount themselves.  The former are currently broken and therefore leak
the link property object.

This patch adds a flags argument to object_property_add_link() so the
caller can specify which refcount behavior they require.  The new
OBJ_PROP_LINK_UNREF_ON_RELEASE flag causes the link pointer to be
unreferenced when the property is deleted.

This fixes refcount leaks in qdev.c, xilinx_axidma.c, xilinx_axienet.c,
s390-virtio-bus.c, virtio-pci.c, virtio-rng.c, and ui/console.c.

Rationale for refcount behavior:

 * hw/core/qdev.c
   - bus children are explicitly unreferenced, don't interfere
   - parent_bus is essentially a read-only property that doesn't hold a
     refcount, don't unref
   - hotplug_handler is leaked, do unref

 * hw/dma/xilinx_axidma.c
   - rx stream "dma" links are set using set_link, therefore they
     need unref
   - tx streams are set using set_link, therefore they need unref

 * hw/net/xilinx_axienet.c
   - same reasoning as hw/dma/xilinx_axidma.c

 * hw/pcmcia/pxa2xx.c
   - pxa2xx bypasses set_link and therefore does not use refcounts

 * hw/s390x/s390-virtio-bus.c
 * hw/virtio/virtio-pci.c
 * hw/virtio/virtio-rng.c
 * ui/console.c
   - set_link is used and there is no explicit unref, do unref
