Akihiko Odaki c821a58ee7 ui/console: Pass placeholder surface to displays
ui/console used to accept NULL as graphic console surface, but its
semantics was inconsistent among displays:
- cocoa and gtk-egl perform NULL dereference.
- egl-headless, spice and spice-egl do nothing.
- gtk releases underlying resources.
- sdl2-2d and sdl2-gl destroys the window.
- vnc shows a message, "Display output is not active."

Fortunately, only virtio-gpu and virtio-gpu-3d assign NULL so
we can study them to figure out the desired behavior. They assign
NULL *except* for the primary display when the device is realized,
reset, or its scanout is disabled. This effectively destroys
windows for the (uninitialized) secondary displays.

To implement the consistent behavior of display device
realization/reset, this change embeds it to the operation
switching the surface. When NULL was given as a new surface when
switching, ui/console will instead passes a placeholder down
to each display listeners.

sdl destroys the window for a secondary console if its surface is a
placeholder. The other displays simply shows the placeholder.

Marc-André Lureau f4f2805ef8 spice: flush drawing before notifying client
This solves the client having slow/outdated VGA/2D console. It's a
regression introduced when the code was switched to render it via opengl

Marc-André Lureau 3af1671852 spice: flush on GL update before notifying client
Since the introduction of spice/virgl support in commit
474114b7 ("spice: add opengl/virgl/dmabuf support"), the drawing isn't
being flushed before notifying the client. This results in
outdated/sluggish drawing on client side, in particular when using the
Linux console.

Marc-André Lureau 3cddb8b9e0 display/ui: add a callback to indicate GL state is flushed
Displaying rendered resources requires blocking qemu GPU to avoid extra
framebuffer copies. For an external display, via Spice currently, there
is a callback to block/unblock the rendering in the same thread.

But with the vhost-user-gpu backend, the qemu process doesn't handle
the rendering itself, and the blocking callback isn't effective.
Instead, the backend must be notified when the display code is done.

Fix this by adding a new GraphicHwOps callback to indicate the GL state
is flushed, and we are done manipulating the shared GL resources. Call
it from gtk and spice display.

Marc-André Lureau a652b12013 spice: delay starting until display are initialized
QEMU used to run qemu_spice.display_init() before vm_start(), and
QXL/display interfaces where started then. Now, vm_start() happens
before QXL/display interfaces are added and Spice server doesn't
automatically start them in this case (fixed in spice git)

Fixes Spice regression introduced after 5.2, with refactoring commits
b4e1a34211 ("vl: remove separate preconfig main_loop") and
facf7c60ee ("vl: initialize displays _after_ exiting preconfiguration"),
probably others.

Markus Armbruster d5938f29fe Clean up inclusion of sysemu/sysemu.h
In my "build everything" tree, changing sysemu/sysemu.h triggers a
recompile of some 5400 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h).

Almost a third of its inclusions are actually superfluous.  Delete
them.  Downgrade two more to qapi/qapi-types-run-state.h, and move one
from char/serial.h to char/serial.c.

hw/semihosting/config.c, monitor/monitor.c, qdev-monitor.c, and
stubs/semihost.c define variables declared in sysemu/sysemu.h without
including it.  The compiler is cool with that, but include it anyway.

This doesn't reduce actual use much, as it's still included into
widely included headers.  The next commit will tackle that.

qemu/event_notifier.h, these numbers drop from 5600 to 2800.  For the
others, they shrink only slightly.

Future spice-server versions will call the client_monitors_config
callback with the monitors list filtered to only include the monitors
of the given display channel (aka QXLInstance).  Luckily this is easily
detectable at runtime, so we can prepare for that in advance and also
make qemu compatible with both old and new spice-server versions.

While being at it also use the console index instead of head number as
array index.  The later doesn't work correctly in case multiple display
devices are present.

Paolo Bonzini 006bf4641b spice-display: fix qemu_spice_cursor_refresh_bh locking
spice-display should not call the ui/console.c functions dpy_cursor_define
and dpy_moues_set with the SimpleSpiceDisplay lock taken.  That will cause
a deadlock, because the DisplayChangeListener callbacks will take the lock
again.  It is also in general a bad idea to invoke generic callbacks with a
lock taken, because it can cause AB-BA deadlocks in the long run.  The only
thing that requires care is that the cursor may disappear as soon as the
mutex is released, so you need an extra cursor_get/cursor_put pair.

updates into a opengl texture, using the helper functions in
ui/console-gl.c.  With this patch applied spice (with gl=on) will

time, i.e. for bios/bootloader (before virtio-gpu driver is loaded)
too.

This should improve performance even using spice (with gl=on) with
non-accelerated stdvga because we stop squeezing all display updates
through a unix/tcp socket and basically using a shared memory transport
instead.

Gerd Hoffmann 474114b730 spice: add opengl/virgl/dmabuf support
This adds support for dma-buf passing to spice.  This makes virtio-gpu
with 3d acceleration work with spice.

Workflow:
 * virglrenderer renders the guest command stream into a texture.
 * qemu exports the texture as dma-buf and passes on that dma-buf
   to spice-server.
 * spice-server passes the dma-buf to spice-client, using unix
   socket file descriptor passing.
 * spice-client asks the window systems composer to render the
   dma-buf to the screen.

Requires cutting edge spice (server) and spice-gtk (client) builds,
from git master branch.

Also requires libvirt managing your qemu instance, and using
"virt-viewer --attach $guest".  libvirt will connect spice-server and
spice-client using unix sockets instead of tcp sockets then, which
is required for file descriptor passing.

Works for the local case (spice server and client on the same machine)
only.  Supporting remote too is planned (by feeding the dma-bufs into
gpu-assisted video encoder), but not there yet.

gl mode is turned off by default, use "-spice gl=on,$otherargs" to
enable it.

Gerd Hoffmann b2af43cc37 spice: surface switch fast path requires same format too.
Commit "555e72f spice: rework mirror allocation, add no-resize fast path"
adds a fast path for surface switches which does't go through the full
primary surface destroy and re-recreation in case the new surface is
identical to the old one (page-flip).  It checks the size only though,
but the format must be identical too.  This patch adds the format check.

Commit "0002a51 ui/spice: Support shared surface for most pixman
formats" increases the chance to actually trigger this.

Daniel P. Berrange ef1e1e0782 maint: avoid useless "if (foo) free(foo)" pattern
The free() and g_free() functions both happily accept
NULL on any platform QEMU builds on. As such putting a
conditional 'if (foo)' check before calls to 'free(foo)'
merely serves to bloat the lines of code.
