2022-03-15ui/cocoa: add option to swap Option and CommandGustavo Noronha Silva
On Mac OS X the Option key maps to Alt and Command to Super/Meta. This change 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.

2022-03-15ui/cocoa: capture all keys and combos when mouse is grabbedGustavo Noronha Silva
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.

2022-03-15ui/cocoa: release mouse when user switches away from QEMU windowCarwyn Ellis
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.

2022-03-04ui: do not create a surface when resizing a GL scanoutMarc-André Lureau
qemu_console_resize() will create a blank surface and replace the current scanout with it if called while the current scanout is GL (texture or dmabuf). This is not only very costly, but also can produce glitches on the display/listener side. Instead, compare the current console size with the fitting console functions, which also works when the scanout is GL. Note: there might be still an unnecessary surface creation on calling qemu_console_resize() when the size is actually changing, but display backends currently rely on DisplaySurface details during dpy_gfx_switch() to handle various resize aspects. We would need more refactoring to handle resize without DisplaySurface, this is left for a future improvement.

2022-03-02ui/cocoa.m: Remove unnecessary NSAutoreleasePoolsPeter Maydell
In commit 6e657e64cdc478 in 2013 we added some autorelease pools to deal with complaints from macOS when we made calls into Cocoa from threads that didn't have automatically created autorelease pools. Later on, macOS got stricter about forbidding cross-thread Cocoa calls, and in commit 5588840ff77800e839d8 we restructured the code to avoid them. This left the autorelease pool creation in several functions without any purpose; delete it. We still need the pool in cocoa_refresh() for the clipboard related code which is called directly there.

2022-03-02ui/cocoa.m: Fix updateUIInfo threading issuesPeter Maydell
The updateUIInfo method makes Cocoa API calls. It also calls back into QEMU functions like dpy_set_ui_info(). To do this safely, we need to follow two rules: * Cocoa API calls are made on the Cocoa UI thread * When calling back into QEMU we must hold the iothread lock Fix the places where we got this wrong, by taking the iothread lock while executing updateUIInfo, and moving the call in cocoa_switch() inside the dispatch_async block. Some of the Cocoa UI methods which call updateUIInfo are invoked as part of the initial application startup, while we're still doing the little cross-thread dance described in the comment just above call_qemu_main(). This meant they were calling back into the QEMU UI layer before we'd actually finished initializing our display and registered the DisplayChangeListener, which isn't really valid. Once updateUIInfo takes the iothread lock, we no longer get away with this, because during this startup phase the iothread lock is held by the QEMU main-loop thread which is waiting for us to finish our display initialization. So we must suppress updateUIInfo until applicationDidFinishLaunching allows the QEMU main-loop thread to continue.

2022-02-21ui/cocoa: Remove allowedFileTypes restriction in SavePanelPhilippe Mathieu-Daudé
setAllowedFileTypes is deprecated in macOS 12. Per Akihiko Odaki [*]: An image file, which is being chosen by the panel, can be a raw file and have a variety of file extensions and many are not covered by the provided list (e.g. "udf"). Other platforms like GTK can provide an option to open a file with an extension not listed, but Cocoa can't. It forces the user to rename the file to give an extension in the list. Moreover, Cocoa does not tell which extensions are in the list so the user needs to read the source code, which is pretty bad. Since this code is harming the usability rather than improving it, simply remove the [NSSavePanel allowedFileTypes:] call, fixing: [2789/6622] Compiling Objective-C object libcommon.fa.p/ui_cocoa.m.o ui/cocoa.m:1411:16: error: 'setAllowedFileTypes:' is deprecated: first deprecated in macOS 12.0 - Use -allowedContentTypes instead [-Werror,-Wdeprecated-declarations] [openPanel setAllowedFileTypes: supportedImageFileTypes]; ^ /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks/AppKit.framework/Headers/NSSavePanel.h:215:49: note: property 'allowedFileTypes' is declared deprecated here @property (nullable, copy) NSArray<NSString *> *allowedFileTypes API_DEPRECATED("Use -allowedContentTypes instead", macos(10.3,12.0)); ^ /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks/AppKit.framework/Headers/NSSavePanel.h:215:49: note: 'setAllowedFileTypes:' has been explicitly marked deprecated here FAILED: libcommon.fa.p/ui_cocoa.m.o [*] https://lore.kernel.org/qemu-devel/4dde2e66-63cb-4390-9538-c032310db3e3@gmail.com/ Suggested-by: Akihiko Odaki <akihiko.odaki@gmail.com> Reviewed-by: Roman Bolshakov <r.bolshakov@yadro.com> Tested-by: Roman Bolshakov <r.bolshakov@yadro.com> Reviewed-by: Christian Schoenebeck <qemu_oss@crudebyte.com> Signed-off-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Message-id: 20220215080307.69550-11-f4bug@amsat.org Reviewed by: Cameron Esfahani <dirty@apple.com> Reviewed-by: Akihiko Odaki <akihiko.odaki@gmail.com> Tested-by: Akihiko Odaki <akihiko.odaki@gmail.com> Signed-off-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

Add a new -audio backend that accepts D-Bus clients/listeners to handle playback & recording, to be exported via the -display dbus.

2021-12-21ui/dbus: add p2p=on/off optionMarc-André Lureau
Add an option to use direct connections instead of via the bus. Clients are accepted with QMP add_client. This allows to provide the D-Bus display without a bus. It also simplifies the testing setup (some CI have issues to setup a D-Bus bus in a container).

2021-12-21ui: add a D-Bus display backendMarc-André Lureau
The "dbus" display backend exports the QEMU consoles and other UI-related interfaces over D-Bus. By default, the connection is established on the session bus, but you can specify a different bus with the "addr" option. The backend takes the "org.qemu" service name, while still allowing further instances to queue on the same name (so you can lookup all the available instances too). It accepts any number of clients at this point, although this is expected to evolve with options to restrict clients, or only accept p2p via fd passing. The interface is intentionally very close to the internal QEMU API, and can be introspected or interacted with busctl/dfeet etc: $ ./qemu-system-x86_64 -name MyVM -display dbus $ busctl --user introspect org.qemu /org/qemu/Display1/Console_0 org.qemu.Display1.Console interface - - - .RegisterListener method h - - .SetUIInfo method qqiiuu - - .DeviceAddress property s "pci/0000/01.0" emits-change .Head property u 0 emits-change .Height property u 480 emits-change .Label property s "VGA" emits-change .Type property s "Graphic" emits-change .Width property u 640 emits-change [...] See the interfaces XML source file and Sphinx docs for the generated API documentations.

2021-12-21ui: simplify gl unblock & flushMarc-André Lureau
GraphicHw.gl_flushed was introduced to notify the device (vhost-user-gpu) that the GL resources (the display scanout) are no longer needed. It was decoupled from QEMU own gl-blocking mechanism, but that difference isn't helping. Instead, we can reuse QEMU gl-blocking and notify virtio_gpu_gl_flushed() when unblocking (to unlock vhost-user-gpu). An extra block/unblock is added arount dpy_gl_update() so existing backends that don't block will have the flush event handled. It will also help when there are no backends associated.
