2023-10-03ui/gtk: fix UI info preconditionMarc-André Lureau1-0/+8
dpy_get_ui_info() shouldn't be called if the underlying GPU doesn't support it. Before the assert() was added and the regression introduced, GTK code used to get "zero" UI info, for ex with a simple VGA device. The assert was added to prevent from calling when there are no console too. The other display backend that calls dpy_get_ui_info() correctly checks that pre-condition. Calling dpy_set_ui_info() is "safe" in this case, it will simply return an error that can be generally ignored. Fixes: commit a92e7bb4c ("ui: add precondition for dpy_get_ui_info()") Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com>

It is true, that there is no problem during runtime from the first sight, because the memory is lost just before qemu exits. Nevertheless, this change is necessary, because AddressSanitizer is not able to recognize this situation and produces crash-report (which is false-positive in fact). Lots of False-Positive warnings are davaluing problems, found with fuzzing, and thus the whole methodology of dynamic analysis.

In commit 6f974c843c ("gtk: overwrite the console.c char driver"), I shared the VC console parse handler with GTK. And later on in commit d8aec9d9 ("display: add -display spice-app launching a Spice client"), I also used it to handle spice-app VC. This is not necessary, the VC console options (width/height/cols/rows) are specific, and unused by tty-level GTK/Spice VC.

2023-05-28ui/gtk: use widget size for cursor motion eventErico Nunes1-5/+3
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.

2022-06-14ui: Deliver refresh rate via QemuUIInfoAkihiko Odaki1-19/+26
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.

2021-07-26ui/gtk: add a keyboard fifo to the VTE consolesVolker Rümelin1-9/+33
Since commit 8eb13bbbac ("ui/gtk: vte: fix sending multiple characeters") it's very easy to lock up QEMU with the GTK ui. If you configure a guest with a serial device and the guest doesn't listen on this device, QEMU will lock up after entering two characters in the serial console. That's because current code uses a busy loop for the chardev write retries and the busy loop doesn't terminate in this case. To fix this problem add a fifo to the VTE consoles and use the chr_accept_input() callback function to write the remaining characters in the queue to the chardev. The fifo has a size of 4096 bytes, so one can copy and paste a fairly large URL or file path.

To handle relative mouse input the event handler needs to move the mouse away from the screen edges. Failing to do so results in the mouse getting stuck at invisible walls. However the current implementation for this is broken on hosts with multiple monitors. With multiple monitors the mouse can be located outside of the current monitor which is not handled by the current code. Also the monitor itself might be located at coordinates different from (0, 0).

2021-03-11ui/gtk: Remove NULL checks in gd_switchAkihiko Odaki1-4/+2
c821a58ee7 ("ui/console: Pass placeholder surface to display") eliminated the possibility that NULL is passed as surface to dpy_gfx_switch and removed some NULL checks from gd_switch, but the removal was not thoroughly. Remaining NULL checks were confusing for Coverity and probably also for humans. This change removes those NULL checks.

2021-03-04ui/console: Pass placeholder surface to displaysAkihiko Odaki1-4/+0
ui/console used to accept NULL as graphic console surface, but its semantics was inconsistent among displays: - cocoa and gtk-egl perform NULL dereference. - egl-headless, spice and spice-egl do nothing. - gtk releases underlying resources. - sdl2-2d and sdl2-gl destroys the window. - vnc shows a message, "Display output is not active." Fortunately, only virtio-gpu and virtio-gpu-3d assign NULL so we can study them to figure out the desired behavior. They assign NULL *except* for the primary display when the device is realized, reset, or its scanout is disabled. This effectively destroys windows for the (uninitialized) secondary displays. To implement the consistent behavior of display device realization/reset, this change embeds it to the operation switching the surface. When NULL was given as a new surface when switching, ui/console will instead passes a placeholder down to each display listeners. sdl destroys the window for a secondary console if its surface is a placeholder. The other displays simply shows the placeholder.

2021-03-04configure: Improve OpenGL dependency detectionsAkihiko Odaki1-0/+14
This has the following visible changes: - GBM is required only for OpenGL dma-buf. - X11 is explicitly required by gtk-egl. - EGL is now mandatory for the OpenGL displays. The last one needs some detailed description. Before this change, EGL was tested only for OpenGL dma-buf with the check of EGL_MESA_image_dma_buf_export. However, all of the OpenGL displays depend on EGL and EGL_MESA_image_dma_buf_export is always defined by epoxy's EGL interface. Therefore, it makes more sense to always check the presence of EGL and say the OpenGL displays are available along with OpenGL dma-buf if it is present.

2021-03-04ui/gtk: vte: fix sending multiple characetersZack Marvel1-1/+10
When using the GTK UI with libvte, multicharacter keystrokes are not sent correctly (such as arrow keys). gd_vc_in should check the CharBackend's can_receive instead of assuming multiple characters can be received. This is not an issue for e.g. the SDL UI because qemu_chr_be_write is called with len=1 for each character (SDL sends more than once keystroke). Modify gd_vc_in to call qemu_chr_be_write multiple times if necessary.
