In vnc_display_open(), if tls-creds is enabled, do object_ref(object
ref 1->2) for tls-creds. While in vnc_display_close(), object_unparent
sets object ref to 1(2->1) and unparent the object for root.
Problem:
1. the object can not be found from the objects_root, while the object
is not finalized.
2. the qemu_opts of tls-creds(id: creds0) is not deleted, so new tls
object with the same id(creds0) can not be delete & add.

When running QEMU's GTK UI without EGL or OGL, the
gd_monitor_update_interval function gets executed and the display refresh
rate gets updated accordingly. However, when using EGL or just regular
OGL, the function never gets executed.
Which is why I decided that the function should be in gd_egl_refresh
where the display output gets updated, in the same vain as how it's done
for normal GTK UIs (aka. those without EGL) - in it's display refresh
function.
Since the gd_monitor_update_interval function now is exposed, we are
going to use it to update the refresh rate.

The gd_egl_refresh function, as the name suggests, is responsible for
refreshing displays when using EGL graphics with QEMU's GTK UI. This is
a perfect candidate for a function to update the refresh rate in.
Since gd_monitor_update_interval is inaccessible from the gd_egl_refresh
function, we need to expose/globalize it in the include/ui/gtk.h file.

Limit the virtual console maximum update interval to
GUI_REFRESH_INTERVAL_DEFAULT. This papers over a integer
overflow bug in gtk3 on Windows where the reported monitor
refresh frequency can be much smaller than the real refresh
frequency.
The gtk bug report can be found here:
https://gitlab.gnome.org/GNOME/gtk/-/issues/3394
On my Windows 10 system gtk reports a monitor refresh rate of
1.511Hz instead of 60.031Hz and slows down the screen update
rate in qemu to a crawl. Provided you are affected by the gtk
bug on Windows, these are the steps to reproduce the issue:
Start qemu with -display gtk and activate all qemu virtual
consoles and notice the reduced qemu refresh rate. Activating
all virtual consoles is necessary, because gui_update() in
ui/console.c uses the minimum of all display change listeners
update interval and not yet activated virtual consoles report
the default update interval (30ms).

Redefining SI prefixes is always wrong. 1s has per definition
1000ms. Remove the misnamed named constant and replace it with

with the implicit unit mHz in refresh_rate_millihz and see why

Anywhere we create a list of just one item or by prepending items
(typically because order doesn't matter), we can use
QAPI_LIST_PREPEND(). But places where we must keep the list in order
by appending remain open-coded until later patches.
Note that as a side effect, this also performs a cleanup of two minor
issues in qga/commands-posix.c: the old code was performing
new = g_malloc0(sizeof(*ret));
which 1) is confusing because you have to verify whether 'new' and
'ret' are variables with the same type, and 2) would conflict with C++
compilation (not an actual problem for this file, but makes
copy-and-paste harder).

Thanks to the monitors' coroutine support (merge commit b7092cda1b),
the screendump handler can trigger a graphic_hw_update(), yield and let
the main loop run until update is done. Then the handler is resumed, and
ppm_save() will write the screen image to disk in the coroutine context.
The IO is still blocking though, as the file is set blocking so far,
this could be addressed by some future change (with other caveats).

With Makefiles that have automatically generated dependencies, you
generated includes are set as dependencies of the Makefile, so that they
are built before everything else and they are available when first
building the .c files.
Alternatively you can use a fine-grained dependency, e.g.
target/arm/translate.o: target/arm/decode-neon-shared.inc.c
With Meson you have only one choice and it is a third option, namely
"build at the beginning of the corresponding target"; the way you
express it is to list the includes in the sources of that target.
The problem is that Meson decides if something is a source vs. a
generated include by looking at the extension: '.c', '.cc', '.m', '.C'
are sources, while everything else is considered an include---including
'.inc.c'.
Use '.c.inc' to avoid this, as it is consistent with our other convention
of using '.rst.inc' for included reStructuredText files. The editorconfig
file is adjusted.

Meson doesn't enjoy the same flexibility we have with Make in choosing
the include path. In particular the tracing headers are using
$(build_root)/$(<D).
In order to keep the include directives unchanged,
the simplest solution is to generate headers with patterns like
"trace/trace-audio.h" and place forwarding headers in the source tree
such that for example "audio/trace.h" includes "trace/trace-audio.h".
This patch is too ugly to be applied to the Makefiles now. It's only
a way to separate the changes to the tracing header files from the
Meson rewrite of the tracing logic.

The only way object_property_add() can fail is when a property with
the same name already exists. Since our property names are all
hardcoded, failure is a programming error, and the appropriate way to
handle it is passing &error_abort.
Same for its variants, except for object_property_add_child(), which
additionally fails when the child already has a parent. Parentage is
also under program control, so this is a programming error, too.
We have a bit over 500 callers. Almost half of them pass
&error_abort, slightly fewer ignore errors, one test case handles
errors, and the remaining few callers pass them to their own callers.
The previous few commits demonstrated once again that ignoring
programming errors is a bad idea.
Of the few ones that pass on errors, several violate the Error API.
The Error ** argument must be NULL, &error_abort, &error_fatal, or a
pointer to a variable containing NULL. Passing an argument of the
latter kind twice without clearing it in between is wrong: if the
first call sets an error, it no longer points to NULL for the second
call. ich9_pm_add_properties(), sparc32_ledma_realize(),
sparc32_dma_realize(), xilinx_axidma_realize(), xilinx_enet_realize()
are wrong that way.
When the one appropriate choice of argument is &error_abort, letting
users pick the argument is a bad idea.
Drop parameter @errp and assert the preconditions instead.
There's one exception to "duplicate property name is a programming
error": the way object_property_add() implements the magic (and

Traditionally, the uint-specific property helpers only offer getters.
When adding object (or class) uint types, one must therefore use the
generic property helper if a setter is needed (and probably duplicate
some code writing their own getters/setters).
This enhances the uint-specific property helper APIs by adding a
bitwise-or'd 'flags' field and modifying all clients of that API to set
this paramater to OBJ_PROP_FLAG_READ. This maintains the current
behaviour whilst allowing others to also set OBJ_PROP_FLAG_WRITE (or use
the more convenient OBJ_PROP_FLAG_READWRITE) in the future (which will
automatically install a setter). Other flags may be added later.

In commit 50290c002c in mid-2019 we introduced some uses of
CLOCK_MONOTONIC which incidentally broke compilation for pre-10.12 OSX
versions (see LP:1861551). We don't intend to fix that, so we might

Commit c388f408b5 added the possibility to list the display
backends using '-display help'. Since the 'none' backend is
is not implemented as a DisplayChangeListenerOps, it is not
registered to the dpys[] array with qemu_display_register(),
and is not listed in the help output.
This might be confusing, as we list it in the man page:
-display type
Select type of display to use. This option is a replacement for
the old style -sdl/-curses/... options. Valid values for type are
none
Do not display video output. The guest will still see an
emulated graphics card, but its output will not be displayed
to the QEMU user. This option differs from the -nographic
option in that it only affects what is done with video
output; -nographic also changes the destination of the serial
and parallel port data.
Fix by manually listing the special 'none' backend in the help.

In my investigation, ZRLE always compresses better than ZLIB so

preferred.
zlib buffer is always reset in zrle_compress_data(), so using offset to
calculate next_out and avail_out is useless.

This reverts commit de3f7de7f4.
Remove VNC optimization to reencode framebuffer update as raw if it's
smaller than the default encoding.
QEMU's implementation was naive and didn't account for the ZLIB z_stream
mutating with each compression. Because of the mutation, simply
resetting the output buffer's offset wasn't sufficient to "rewind" the
operation. The mutated z_stream would generate future zlib blocks which
referred to symbols in past blocks which weren't sent. This would lead
to artifacting.
Considering that ZRLE is never larger than raw and even though ZLIB can
occasionally be fractionally larger than raw, the overhead of
implementing this optimization correctly isn't worth it.

Because some VMs in QEMU can get GPU virtualization (using technologies
such as iGVT-g, as mentioned previously), they could produce a video
output that had a higher display refresh rate than of what the GTK
display was displaying. (fxp. Playing a video game inside of a Windows
VM at 60 Hz, while the output stood locked at 33 Hz because of defaults
set in include/ui/console.h)
Since QEMU does indeed have internal systems for determining frame
times as defined in ui/console.c.
The code checks for a variable called update_interval that it later
uses for time calculation. This variable, however, isn't defined
anywhere in ui/gtk.c and instead ui/console.c just sets it to
GUI_REFRESH_INTERVAL_DEFAULT which is 30
update_interval represents the number of milliseconds per display
refresh, and by doing some math we get that 1000/30 = 33.33... Hz
This creates the mentioned problem and what this patch does is that it
checks for the display refresh rate reported by GTK itself (we can take
this as a safe value) and just converts it back to a number of
milliseconds per display refresh.

macOS API documentation says that before applicationDidFinishLaunching
is called, any events will not be processed. However, some events are
fired before it is called in macOS Catalina. This causes deadlock of
iothread_lock in handleEvent while it will be released after the
app_started_sem is posted.
This patch avoids processing events before the app_started_sem is
posted to prevent this deadlock.

Currently when qemu receives a vnc connect, it creates a 'VncState' to
represent this connection. In 'vnc_worker_thread_loop' it creates a
local 'VncState'. The connection 'VcnState' and local 'VncState' exchange
data in 'vnc_async_encoding_start' and 'vnc_async_encoding_end'.
In 'zrle_compress_data' it calls 'deflateInit2' to allocate the libz library
opaque data. The 'VncState' used in 'zrle_compress_data' is the local
'VncState'. In 'vnc_zrle_clear' it calls 'deflateEnd' to free the libz
library opaque data. The 'VncState' used in 'vnc_zrle_clear' is the connection
'VncState'. In currently implementation there will be a memory leak when the
vnc disconnect. Following is the asan output backtrack:
Direct leak of 29760 byte(s) in 5 object(s) allocated from:
0 0xffffa67ef3c3 in __interceptor_calloc (/lib64/libasan.so.4+0xd33c3)
1 0xffffa65071cb in g_malloc0 (/lib64/libglib-2.0.so.0+0x571cb)
2 0xffffa5e968f7 in deflateInit2_ (/lib64/libz.so.1+0x78f7)
3 0xaaaacec58613 in zrle_compress_data ui/vnc-enc-zrle.c:87
4 0xaaaacec58613 in zrle_send_framebuffer_update ui/vnc-enc-zrle.c:344
5 0xaaaacec34e77 in vnc_send_framebuffer_update ui/vnc.c:919
6 0xaaaacec5e023 in vnc_worker_thread_loop ui/vnc-jobs.c:271
7 0xaaaacec5e5e7 in vnc_worker_thread ui/vnc-jobs.c:340
8 0xaaaacee4d3c3 in qemu_thread_start util/qemu-thread-posix.c:502
9 0xffffa544e8bb in start_thread (/lib64/libpthread.so.0+0x78bb)
10 0xffffa53965cb in thread_start (/lib64/libc.so.6+0xd55cb)
This is because the opaque allocated in 'deflateInit2' is not freed in
'deflateEnd'. The reason is that the 'deflateEnd' calls 'deflateStateCheck'
and in the latter will check whether 's->strm != strm'(libz's data structure).
This check will be true so in 'deflateEnd' it just return 'Z_STREAM_ERROR' and
not free the data allocated in 'deflateInit2'.
The reason this happens is that the 'VncState' contains the whole 'VncZrle',
so when calling 'deflateInit2', the 's->strm' will be the local address.
So 's->strm != strm' will be true.
To fix this issue, we need to make 'zrle' of 'VncState' to be a pointer.
Then the connection 'VncState' and local 'VncState' exchange mechanism will
work as expection. The 'tight' of 'VncState' has the same issue, let's also turn
it to a pointer.

This allows to receive mouse and keyboard events from
a Barrier server.
This is enabled by adding the following parameter on the
command line
... -object input-barrier,id=$id,name=$name ...
Where $name is the name declared in the screens section of barrier.conf
The barrier server (barriers) must be configured and must run on the
local host.
For instance:
section: screens
localhost:
...
VM-1:
...
end
section: links
localhost:
right = VM-1
VM-1:
left = localhost
end
Then on the QEMU command line:
... -object input-barrier,id=barrie0,name=VM-1 ...
When the mouse will move out of the screen of the local host on
the right, the mouse and the keyboard will be grabbed and all
related events will be send to the guest OS.
This is usefull when qemu is configured without emulated graphic card
but with a VFIO attached graphic card.
More information about Barrier can be found at:
https://github.com/debauchee/barrier
This avoids to install the Barrier server in the guest OS,
for instance when it is not supported or during the installation.

Fix egl_fb_read() to use the (destination) surface size instead of the
(source) framebuffer source for glReadPixels. Pass the DisplaySurface
instead of the pixeldata pointer to egl_fb_read() to make this possible.
With that in place framebuffer reads work fine even if the surface and
framebuffer sizes don't match, so we can remove the guest-triggerable
asserts in egl_scanout_flush().

sysemu/sysemu.h is a rather unfocused dumping ground for stuff related
to the system-emulator. Evidence:
* It's included widely: in my "build everything" tree, changing
sysemu/sysemu.h still triggers a recompile of some 1100 out of 6600
objects (not counting tests and objects that don't depend on
qemu/osdep.h, down from 5400 due to the previous two commits).
* It pulls in more than a dozen additional headers.
Split stuff related to run state management into its own header
sysemu/runstate.h.
Touching sysemu/sysemu.h now recompiles some 850 objects. qemu/uuid.h
also drops from 1100 to 850, and qapi/qapi-types-run-state.h from 4400
to 4200. Touching new sysemu/runstate.h recompiles some 500 objects.

Almost a third of its inclusions are actually superfluous. Delete

hw/semihosting/config.c, monitor/monitor.c, qdev-monitor.c, and

docs/devel/tracing.txt explains "since many source files include
trace.h, [the generated trace.h use] a minimum of types and other
header files included to keep the namespace clean and compile times
and dependencies down."
Commit 4815185902 "trace: Add per-vCPU tracing states for events with
the 'vcpu' property" made them all include qom/cpu.h via
control-internal.h. qom/cpu.h in turn includes about thirty headers.
Ouch.
Per-vCPU tracing is currently not supported in sub-directories'
trace-events. In other words, qom/cpu.h can only be used in
trace-root.h, not in any trace.h.
Split trace/control-vcpu.h off trace/control.h and
trace/control-internal.h. Have the generated trace.h include
trace/control.h (which no longer includes qom/cpu.h), and trace-root.h
include trace/control-vcpu.h (which includes it).
The resulting improvement is a bit disappointing: in my "build
everything" tree, some 1100 out of 6600 objects (not counting tests
and objects that don't depend on qemu/osdep.h) depend on a trace.h,
and about 600 of them no longer depend on qom/cpu.h. But more than
1300 others depend on trace-root.h. More work is clearly needed.

6300 qapi/qapi-builtin-types.h
5700 qapi/qapi-types-run-state.h
3900 qapi/qapi-types-common.h
3300 qapi/qapi-types-sockets.h

3000 qapi/qapi-types-block-core.h
2800 qapi/qapi-types-block.h
1300 qapi/qapi-types-net.h
Clean up headers to include generated QAPI headers only where needed.
Impact is negligible except for hw/qdev-properties.h.
This header includes qapi/qapi-types-block.h and
qapi/qapi-types-misc.h. They are used only in expansions of property
definition macros such as DEFINE_PROP_BLOCKDEV_ON_ERROR() and
DEFINE_PROP_OFF_AUTO(). Moving their inclusion from
hw/qdev-properties.h to the users of these macros avoids pointless
recompiles. This is how other property definition macros, such as
DEFINE_PROP_NETDEV(), already work.
Improves things for some of the top scorers:
3600 qapi/qapi-types-common.h
2800 qapi/qapi-types-sockets.h
900 qapi/qapi-types-misc.h
2200 qapi/qapi-types-crypto.h

Linux terminal behavior (coming from vt100 I think) is somewhat strange
when it comes to line wraps: When a character is printed to the last
char cell of a line the cursor does NOT jump to the next line but stays
where it is. The line feed happens when the next character is printed.
So the valid range for the cursor position is not 0 .. width-1 but
0 .. width, where x == width represents the state where the line is
full but the cursor didn't jump to the next line yet.
The code for the 'clear from start of line' control sequence (ESC[1K)
fails to handle this corner case correctly and may call
console_clear_xy() with x == width. That will incorrectly clear the
first char cell of the next line, or in case the cursor happens to be on
the last line overflow the cell buffer by one character (three bytes).
Add a check to the loop to fix that.
Didn't spot any other places with the same problem. But it's easy to
miss that corner case, so also allocate one extra cell as precaution, so
in case we have simliar issues lurking elsewhere it at least wouldn't be
a buffer overflow.

On Mojave, absolute input device, i.e. tablet, had trouble re-grabbing
the cursor in re-entry into the virtual screen area. In some cases,
the `window` property of NSEvent object was nil after cursor exiting from
window, hinting that the `-locationInWindow` method would return value in
screen coordinates. The current implementation used raw locations from
NSEvent without considering whether the value was for the window coordinates
or the macOS screen coordinates, nor the zooming factor for Zoom-to-Fit in
fullscreen mode.
In fullscreen mode, the fullscreen cocoa window might not be the key
window, therefore the location of event in virtual coordinates should
suffice.
This patches fixed boundary check methods for cursor in normal
and fullscreen with/without Zoom-to-Fit in Mojave.
Note: CGRect, -convertRectToScreen: and -convertRectFromScreen: were

The VNC server has historically had support for ACLs to check both the
SASL username and the TLS x509 distinguished name. The VNC server was
responsible for creating the initial ACL, and the client app was then
responsible for populating it with rules using the HMP 'acl_add' command.
This is not satisfactory for a variety of reasons. There is no way to
populate the ACLs from the command line, users are forced to use the
HMP. With multiple network services all supporting TLS and ACLs now, it
is desirable to be able to define a single ACL that is referenced by all
services.
To address these limitations, two new options are added to the VNC
server CLI. The 'tls-authz' option takes the ID of a QAuthZ object to
use for checking TLS x509 distinguished names, and the 'sasl-authz'
option takes the ID of another object to use for checking SASL usernames.
In this example, we setup two authorization rules. The first allows any
client with a certificate issued by the 'RedHat' organization in the
'London' locality. The second ACL allows clients with either the
'joe@REDHAT.COM' or 'fred@REDHAT.COM' kerberos usernames. Both checks
must pass for the user to be allowed.

vnc aborts display update jobs on video mode switches and page flips.
That can cause vnc update stalls in case an unfinished vnc job gets

Fix that by copying the state from job_update back to update in that
case.
Reports complain about stalls with two or more clients being connected
at the same time, on some but not all connections. I suspect it can
also happen with a single connection, multiple connections only make
this more much likely to happen.

This makes use of wide curses functions instead of 8bit functions. This
allows to type e.g. accented letters.
Unfortunately, key codes are then returned with values that could be
confused with wide characters by ncurses, so we need to add a maybe_keycode
variable to know whether the returned value is a key code or a character
(curses with wide support), or possibly both (curses without wide support).
The translation tables thus also need to be separated into key code
translation and character translation. The curses2foo helper makes it easier
to use them.

The OSX Mojave release is more picky about enforcing the Cocoa API
restriction that only the main thread may perform UI calls. To
accommodate this we need to restructure the Cocoa code:
* the special OSX main() creates a second thread and uses
that to call the vl.c qemu_main(); the original main
thread goes into the OSX event loop
* the refresh, switch and update callbacks asynchronously
tell the main thread to do the necessary work
* the refresh callback no longer does the "get events from the
UI event queue and handle them" loop, since we now use
the stock OSX event loop. Instead our NSApplication sendEvent
method will either deal with them or pass them on to OSX
All these things have to be changed in one commit, to avoid
breaking bisection.
Note that since we use dispatch_get_main_queue(), this bumps
our minimum version requirement to OSX 10.10 Yosemite (released
in 2014, unsupported by Apple since 2017).

The new QAuthZ subclasses provide a superset of the functionality in

commands are converted to use the new QAuthZSimple data type instead

Add a new display backend that will configure Spice to allow a remote
client to control QEMU in a similar fashion as other QEMU display
backend/UI like GTK.
For this to work, it will set up Spice server with a unix socket, and
register a VC chardev that will be exposed as Spice ports. A QMP
monitor is also exposed as a Spice port, this allows the remote client
fuller qemu control and state handling.
- doesn't handle VC set_echo() - this doesn't seem a strong
requirement, very few front-end use it
- spice options can be tweaked with other -spice arguments
- Windows support shouldn't be hard to do, but will probably use a TCP
port instead

Passing several -spice options to qemu command line, or calling
several time qemu_opts_set() will ignore all but the first option
list. Since the spice server is a singleton, it makes sense to merge
all the options, the last value being the one taken into account.
This changes the behaviour from, for ex:
$ qemu... -spice port=5900 -spice port=5901 -> port: 5900
to:
$ qemu... -spice port=5900 -spice port=5901 -> port: 5901
(if necessary we could instead produce an error when an option is
given twice, although this makes handling default values and such more
complicated)

The Spice server doesn't like to be started or stopped twice . It
aborts with:
(process:6191): Spice-ERROR **: 19:29:35.912: red-worker.c:623:handle_dev_start: assertion `!worker->running' failed
It's easy to avoid that situation since qemu spice_display_is_running
tracks the server state.
After the commit "spice: do not stop spice if VM is paused", it will
be possible to pause and resume the VM, and this will call
qemu_spice_display_start() twice. The easiest is to add a check for
spice_display_is_running with this patch to avoid the assert.

The license information in this file is very messy. A short note at
the beginning says GPL first, but the long boilerplate code then
talks about "GNU Lesser General Public License version 2.0". First,
there is no such version of the "GNU Lesser GPL", it only started with
version 2.1. In version 2.0, it was still called "GNU Library GPL"
instead. Second, you can easily get the license of this file wrong
if you only quickly glance at the long boilerplate code.
Anyway, looking at the text of the LGPL (see COPYING.LIB in the top
directory), the license clearly states in section "3." that one should
rather replace the license information with the GPL information in
such a case of a mixture instead. Thus let's clean up the confusing
statements and use the proper GPL text only.

When the user raises their fingers from the touchpad, we may receive a
GDK_SMOOTH_SCROLL event with delta_y == 0. Avoid generating a WHEEL_UP
event in this situation.

SDL1.2 was deprecated in the 2.12.0 release with:
commit e52c6ba341
Author: Daniel P. Berrange <berrange@redhat.com>
Date: Mon Jan 15 14:25:33 2018 +0000
ui: deprecate use of SDL 1.2 in favour of 2.0 series
The SDL 2.0 release was made in Aug, 2013:
https://www.libsdl.org/release/
That will soon be 4 + 1/2 years ago, which is enough time to consider
the 2.0 series widely supported.
Thus we deprecate the SDL 1.2 support, which will allow us to delete it
in the last release of 2018. By this time, SDL 2.0 will be more than 5
years old.

This patch adds a new option to the input-linux object:
grab-toggle=[key-combo]
The key combination can be one of the following:
* ctrl-ctrl
* alt-alt
* meta-meta
* scrolllock
* ctrl-scrolllock
The user can pick any of these key combinations. The VM's grab
of the evdev device will be toggled when the key combination is
pressed.
Any invalid setting will result in an error. No setting will
result in the current default of ctrl-ctrl.
The right and left ctrl key both work for Ctrl-Scrolllock.
If scrolllock is selected as one of the grab-toggle keys, it
will be entirely disabled and not passed to the guest at all.
This is to prevent enabling it while attempting to leave or enter
the VM. On the host, scrolllock can be disabled using xmodmap.
First, find the modifier that Scroll_Lock is bound to:
$ xmodmap -pm
Then, remove Scroll_Lock from it, replacing modX with the modifier:
$ xmodmap -e 'remove modX = Scroll_Lock'
If Scroll_Lock is not bound to any modifier, it is already disabled.
To save the changes, add them to your xinitrc.

It was assumed that mesa provides the necessary X11 includes,

When size and format of the display surface stays the same we can just
tag the guest display as dirty and be done with it.
There is no need need to resize the vnc server display or to touch the
vnc client dirty bits. On the next refresh cycle
vnc_refresh_server_surface() will check for actual display content
changes and update the client dirty bits as needed.
The desktop resize and framebuffer format notifications to the vnc
client will be skipped too.

Modern desktop environments can render icons at very large sizes,
especially with high DPI screens. Providing a 32x32 pixel bitmap is
nowhere near sufficient anymore.
When displayed in GNOME shell the QEMU icon looks awful, having been
scaled up to at least x4 its base size. This is compounded by the fact
that the BMP file doesn't do transparency, so while we've removed white
pixels, we still have anti-aliased nearly-white pixels which make the
logo look appalling on black backgrounds.
Loading a high resolution PNG icon addresses both problems, but requires
use of the extra SDL2_image library.

The icon associated with a GtkWindow is just a hint to window managers
and not all of them will honour it. Some will instead want to show the
icon listed by the .desktop file. The desktop file is located based on
the application ID, which is set using g_set_prgname. QEMU has not
historically provided a desktop file or set its app ID, so it got a
broken icon in GNOME shell, which is now fixed.

QEMU currently installs logos to $prefix/share/qemu/ which means no GUI
toolkit or applications can find them by default.
The accepted standards for desktop applications declare that application
logos / icons should be installed under $prefix/share/icons, so use this
directory location.
Pre-rendered icons are provided at the standard sizes expected for GUI
applications, along with the scalable SVG, to ensure maximum portability.
The PNGs are rendered from the SVG using inkscape, however, this is not
wired up into the default make rules to avoid requiring inkscape as a
mandatory tool in build systems / developer workstations.
