72ce36f77c ui/clipboard: reset the serial state on reset
Not only we have to reset the vdagent clipboards serial state, but also
the current QEMU clipboards info serial (the value is currently used by
qemu_clipboard_check_serial, only used by -display dbus).

bab6a301c5 ui/cocoa: Run qemu_init in the main thread
This work is based on:
https://patchew.org/QEMU/20220317125534.38706-1-philippe.mathieu.daude@gmail.com/

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.

88738ea40b ui/console: fix qemu_console_resize() regression
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.

to set the object manager server. This is causing dbus-display-test to

52eaefd36c ui/cocoa: Take refresh rate into account
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.

713911a107 ui/cocoa: Fix switched_to_fullscreen warning
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

aeffd071ed ui: Deliver refresh rate via QemuUIInfo
This change adds a new member, refresh_rate to QemuUIInfo in
include/ui/console.h. It represents the refresh rate of the
physical display backend, and it is more appropriate than
GUI update interval as the refresh rate which the emulated device
reports:
- sdl may set GUI update interval shorter than the refresh rate
  of the physical display to respond to user-generated events.
- sdl and vnc aggressively changes GUI update interval, but
  a guests is typically not designed to respond to frequent
  refresh rate changes, or frequent "display mode" changes in
  general. The frequency of refresh rate changes of the physical
  display backend matches better to the guest's expectation.

QemuUIInfo also has other members representing "display mode",
which makes it suitable for refresh rate representation. It has
a throttling of update notifications, and prevents frequent changes
of the display mode.

09053670c9 ui/gtk-gl-area: create the requested GL context version
Since about 2018 virglrenderer (commit fa835b0f88 "vrend: don't
hardcode context version") tries to open the highest available GL
context version. This is done by creating the known GL context
versions from the highest to the lowest until (*create_gl_context)
returns a context != NULL.

This does not work properly with
the current QEMU gd_gl_area_create_context() function, because
gdk_gl_context_realize() on Wayland creates a version 3.0 legacy
context if the requested GL context version can't be created.

In order for virglrenderer to find the highest available GL
context version, return NULL if the created context version is
lower than the requested version.

This fixes the following error:
QEMU started with -device virtio-vga-gl -display gtk,gl=on.
Under Wayland, the guest window remains black and the following
information can be seen on the host.

gl_version 30 - compat profile
(qemu:5978): Gdk-WARNING **: 16:19:01.533:

To reproduce this error, an OpenGL driver is required on the host
that doesn't have the latest OpenGL extensions fully implemented.
An example for this is the Intel i965 driver on a Haswell processor.

9eafdeeac3 ui: Switch "-display sdl" to use the QAPI parser
The "-display sdl" option still uses a hand-crafted parser for its
parameters since we didn't want to drag an interface we considered
somewhat flawed into the QAPI schema. Since the flaws are gone now,
it's time to QAPIfy.

This introduces the new "DisplaySDL" QAPI struct that is used to hold
the parameters that are unique to the SDL display. The only specific
parameter is currently "grab-mod" that is used to specify the required
modifier keys to escape from the mouse grabbing mode.

Let's use SocketAddressList instead of dynamic arrays.
Benefits:
 - Automatic cleanup: don't need specific freeing function and drop
   some gotos.
 - Less indirection: no triple asterix anymore!
 - Prepare for the following commit, which will reuse new interface of

9a0a119a38 Added parameter to take screenshot with screendump as PNG
Currently screendump only supports PPM format, which is un-compressed. Added
a "format" parameter to QMP and HMP screendump command to support PNG image
capture using libpng.

QMP example usage:
{ "execute": "screendump", "arguments": { "filename": "/tmp/image",
"format":"png" } }

HMP example usage:
screendump /tmp/image -f png

80dd5aff1b block: add 'force' parameter to 'blockdev-change-medium' command
'blockdev-change-medium' is a convinient wrapper for the following
sequence of commands:
 * blockdev-open-tray
 * blockdev-remove-medium
 * blockdev-insert-medium
 * blockdev-close-tray
and should be used f.e. to change ISO image inside the CD-ROM tray.
Though the guest could lock the tray and some linux guests like
CentOS 8.5 actually does that. In this case the execution if this
command results in the error like the following:
  Device 'scsi0-0-1-0' is locked and force was not specified,
  wait for tray to open and try again.

This situation is could be resolved 'blockdev-open-tray' by passing
flag 'force' inside. Thus is seems reasonable to add the same
capability for 'blockdev-change-medium' too.

e03b56863d Replace config-time define HOST_WORDS_BIGENDIAN
Replace a config-time define with a compile time condition
define (compatible with clang and gcc) that must be declared prior to
its usage. This avoids having a global configure time define, but also
prevents from bad usage, if the config header wasn't included before.

This can help to make some code independent from qemu too.

gcc supports __BYTE_ORDER__ from about 4.6 and clang from 3.2.

g_new(T, n) is neater than g_malloc(sizeof(T) * n).  It's also safer,
for two reasons.  One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.

This commit only touches allocations with size arguments of the form
sizeof(T).

swaps them around so that Alt is the key closer to the space bar and Meta/Super
is between Control and Alt, like on non-Mac keyboards.

It is a cocoa display option, disabled by default.

f844cdb997 ui/cocoa: capture all keys and combos when mouse is grabbed
Applications such as Gnome may use Alt-Tab and Super-Tab for different
purposes, some use Ctrl-arrows so we want to allow qemu to handle
everything when it captures the mouse/keyboard.

However, Mac OS handles some combos like Command-Tab and Ctrl-arrows
at an earlier part of the event handling chain, not letting qemu see it.

We add a global Event Tap that allows qemu to see all events when the
mouse is grabbed. Note that this requires additional permissions.

69221df8cd ui/cocoa: release mouse when user switches away from QEMU window
This resolves an issue where using command-tab to switch between QEMU
and other windows on the host can leave the mouse pointer visible.

By releasing the mouse when the user switches away, the user must left
click on the QEMU window when switching back in order to hide the
pointer and return control to the guest.

This appraoch ensures that the calls to NSCursor hide and unhide are
always balanced and thus work correctly when invoked.
