Windows sends an extra left control key up/down input event for
every right alt key up/down input event for keyboards with
international layout. Since commit 830473455f ("ui/sdl2: fix
handling of AltGr key on Windows") QEMU uses a Windows low level
keyboard hook procedure to reliably filter out the special left
control key and to grab the keyboard on Windows.
The SDL2 version 2.0.16 introduced its own Windows low level
keyboard hook procedure to grab the keyboard. Windows calls this
callback before the QEMU keyboard hook procedure. This disables
the special left control key filter when the keyboard is grabbed.
To fix the problem, disable the SDL2 Windows low level keyboard
hook procedure.

The gd_motion_event size has some calculations for the cursor position,
which also take into account things like different size of the
framebuffer compared to the window size.
The use of window size makes things more difficult though, as at least
in the case of Wayland includes the size of ui elements like a menu bar
at the top of the window. This leads to a wrong position calculation by
a few pixels.
Fix it by using the size of the widget, which already returns the size
of the actual space to render the framebuffer.

When we take a PNG screenshot the ordering of the colour channels in
the data is not correct, resulting in the image having weird
colouring compared to the actual display. (Specifically, on a
little-endian host the blue and red channels are swapped; on
big-endian everything is wrong.)
This happens because the pixman idea of the pixel data and the libpng
idea differ. PIXMAN_a8r8g8b8 defines that pixels are 32-bit values,
with A in bits 24-31, R in bits 16-23, G in bits 8-15 and B in bits
0-7. This means that on little-endian systems the bytes in memory
are
B G R A
and on big-endian systems they are
A R G B
libpng, on the other hand, thinks of pixels as being a series of
values for each channel, so its format PNG_COLOR_TYPE_RGB_ALPHA
always wants bytes in the order
R G B A
This isn't the same as the pixman order for either big or little
endian hosts.
The alpha channel is also unnecessary bulk in the output PNG file,
because there is no alpha information in a screenshot.
To handle the endianness issue, we already define in ui/qemu-pixman.h
various PIXMAN_BE_* and PIXMAN_LE_* values that give consistent
byte-order pixel channel formats. So we can use PIXMAN_BE_r8g8b8 and
PNG_COLOR_TYPE_RGB, which both have an in-memory byte order of
R G B
and 3 bytes per pixel.
(PPM format screenshots get this right; they already use the
PIXMAN_BE_r8g8b8 format.)

A warning, "qemu: warning: console: no gl-unblock within" followed by
guest scanout lockup can happen if dpy_gl_update is called in a row
and the second call is made before gd_draw_event scheduled by the first
call is taking place. This is because draw call returns without decrementing
gl_block ref count if the dmabuf was already submitted as shown below.
(gd_gl_area_draw/gd_egl_draw)
if (dmabuf) {
if (!dmabuf->draw_submitted) {
return;
} else {
dmabuf->draw_submitted = false;
}
}
So it should not schedule any redundant draw event in case draw_submitted is
already set in gd_egl_fluch/gd_gl_area_scanout_flush.

improve error handling during module load, by changing:

void module_load_qom(const char *type);
to:
int module_load(const char *prefix, const char *name, Error **errp);
int module_load_qom(const char *type, Error **errp);
where the return value is:
-1 on module load error, and errp is set with the error
0 on module or one of its dependencies are not installed
1 on module load success
2 on module load success (module already loaded or built-in)
module_load_qom_one has been introduced in:
commit 28457744c3 ("module: qom module support"), which built on top of
module_load_one, but discarded the bool return value. Restore it.
Adapt all callers to emit errors, or ignore them, or fail hard,
as appropriate in each context.
Replace the previous emission of errors via fprintf in _some_ error
conditions with Error and error_report, so as to emit to the appropriate
target.
A memory leak is also fixed as part of the module_load changes.
audio: when attempting to load an audio module, report module load errors.
Note that still for some callers, a single issue may generate multiple
error reports, and this could be improved further.
Regarding the audio code itself, audio_add() seems to ignore errors,
and this should probably be improved.
block: when attempting to load a block module, report module load errors.
For the code paths that already use the Error API, take advantage of those
to report module load errors into the Error parameter.
For the other code paths, we currently emit the error, but this could be
improved further by adding Error parameters to all possible code paths.
console: when attempting to load a display module, report module load errors.
qdev: when creating a new qdev Device object (DeviceState), report load errors.
If a module cannot be loaded to create that device, now abort execution
(if no CONFIG_MODULE) or exit (if CONFIG_MODULE).
qom/object.c: when initializing a QOM object, or looking up class_by_name,
report module load errors.
qtest: when processing the "module_load" qtest command, report errors
in the load of the module.

Simplify the initialization dance by running qemu_init() in the main
thread before the Cocoa event loop starts. The secondary thread only
runs only qemu_main_loop() and qemu_cleanup().
This fixes a case where addRemovableDevicesMenuItems() calls
qmp_query_block() while expecting the main thread to still hold
the BQL.
Overriding the code after calling qemu_init() is done by dynamically
replacing a function pointer variable, qemu_main when initializing
ui/cocoa, which unifies the static implementation of main() for
builds with ui/cocoa and ones without ui/cocoa.

The display may be corrupted when changing screen colour depth in
qemu-system-ppc/MacOS since 7.0.
Do not short-cut qemu_console_resize() if the surface is backed by vga
vram. When the scanout isn't set, or it is already allocated, or opengl,
and the size is fitting, we still avoid the reallocation & replace path.
Fixes: commit cb8962c1 ("ui: do not create a surface when resizing a GL scanout")

Some files wrongly contain the same word twice in a row.
One of them should be removed or replaced.

Without CONFIG_GBM, compiling dbus-display fails with
../ui/dbus.c: In function ‘dbus_create_context’:

../ui/dbus.c:47:20: note: each undeclared identifier is reported only once for each function it appears in
and many other similar errors, because include/ui/egl-helpers.h only has
these declaration if gbm is found on the system.

The patch adds "show_tabs" command line option for GTK ui similar to
"grab_on_hover". This option allows tabbed view mode to not have to be
enabled by hand at each start of the VM.

The D-Bus connection starts processing messages before QEMU has the time
to set the object manager server. This is causing dbus-display-test to
fail randomly with:
ERROR:../tests/qtest/dbus-display-test.c:68:test_dbus_display_vm:
assertion failed
(qemu_dbus_display1_vm_get_name(QEMU_DBUS_DISPLAY1_VM(vm)) ==
"dbus-test"): (NULL == "dbus-test") ERROR
Use the delayed message processing flag and method to avoid that
situation.
(the bus connection doesn't need a fix, as the initialization is done
synchronously)

Retrieve the refresh rate of the display and reflect it with
dpy_set_ui_info() and update_displaychangelistener(), allowing the
guest and DisplayChangeListener to consume the information.
The information will be used as a hint how often the display should
be updated. For example, when we run 30 Hz physical display updates
it is pointless for the guest to update the screen at 60Hz
frequency, the guest can spare some work instead.

I noticed this error while building QEMU on Mac OS X:
[1040/1660] Compiling Objective-C object libcommon.fa.p/ui_cocoa.m.o
../ui/cocoa.m:803:17: warning: variable 'switched_to_fullscreen' set but not used [-Wunused-but-set-variable]
static bool switched_to_fullscreen = false;
^
1 warning generated.
I think the behavior is fine if you remove "switched_to_fullscreen", I can
still switch in and out of mouse grabbed mode and fullscreen mode with this
change, and Command keycodes will only be passed to the guest if the mouse
is grabbed, which I think is the right behavior. I'm not sure why a static
piece of state was needed to handle that in the first place. Perhaps the
refactoring of the flags-state-change fixed that by toggling the Command
keycode on.
I tested this with an Ubuntu core image on macOS 12.4
wget https://cdimage.ubuntu.com/ubuntu-core/18/stable/current/ubuntu-core-18-i386.img.xz
xz -d ubuntu-core-18-i386.img.xz
