2022-11-23ui/gtk: prevent ui lock up when dpy_gl_update called again before current ↵Dongwon Kim
draw event occurs 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.

2022-11-23gtk: disable GTK Clipboard with a new meson optionClaudio Fontana
The GTK Clipboard implementation may cause guest hangs. Therefore implement new configure switch: --enable-gtk-clipboard, as a meson option disabled by default, which warns in the help text about the experimental nature of the feature. Regenerate the meson build options to include it. The initialization of the clipboard is gtk.c, as well as the compilation of gtk-clipboard.c are now conditional on this new option to be set.

2022-11-06module: add Error arguments to module_load and module_load_qomClaudio Fontana
improve error handling during module load, by changing: bool module_load(const char *prefix, const char *lib_name); 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 28457744c345 ("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.

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.

2022-07-13ui/cocoa: Take refresh rate into accountAkihiko Odaki
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.

2022-07-13ui/cocoa: Fix switched_to_fullscreen warningPeter Delevoryas
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.

2022-06-14ui: Deliver refresh rate via QemuUIInfoAkihiko Odaki
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.

2022-06-14ui/gtk-gl-area: create the requested GL context versionVolker Rümelin
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: gdk_gl_context_set_required_version - GL context versions less than 3.2 are not supported.

2022-06-03ui: Switch "-display sdl" to use the QAPI parserThomas Huth
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.
