2021-07-26ui/gtk: add a keyboard fifo to the VTE consolesVolker Rümelin
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.

The surfaces created with former qemu_create_message_surface did not display the content from the guest and always contained simple messages describing the reason. A display backend may want to hide the window showing such a surface.

2021-03-04configure: Improve OpenGL dependency detectionsAkihiko Odaki
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.

2021-02-04display/ui: add a callback to indicate GL state is flushedMarc-André Lureau
Displaying rendered resources requires blocking qemu GPU to avoid extra framebuffer copies. For an external display, via Spice currently, there is a callback to block/unblock the rendering in the same thread. But with the vhost-user-gpu backend, the qemu process doesn't handle the rendering itself, and the blocking callback isn't effective. Instead, the backend must be notified when the display code is done. Fix this by adding a new GraphicHwOps callback to indicate the GL state is flushed, and we are done manipulating the shared GL resources. Call it from gtk and spice display.

The gd_egl_refresh function, as the name suggests, is responsible for refreshing displays when using EGL graphics with QEMU's GTK UI. This is a perfect candidate for a function to update the refresh rate in. Since gd_monitor_update_interval is inaccessible from the gd_egl_refresh function, we need to expose/globalize it in the include/ui/gtk.h file.

Redefining SI prefixes is always wrong. 1s has per definition 1000ms. Remove the misnamed named constant and replace it with a comment explaining the frequency to period conversion in two simple steps. Now you can cancel out the unit mHz in the comment with the implicit unit mHz in refresh_rate_millihz and see why the implicit unit ms for update_interval remains.

2020-01-14display/gtk: get proper refreshrateNikola Pavlica
Because some VMs in QEMU can get GPU virtualization (using technologies such as iGVT-g, as mentioned previously), they could produce a video output that had a higher display refresh rate than of what the GTK display was displaying. (fxp. Playing a video game inside of a Windows VM at 60 Hz, while the output stood locked at 33 Hz because of defaults set in include/ui/console.h) Since QEMU does indeed have internal systems for determining frame times as defined in ui/console.c. The code checks for a variable called update_interval that it later uses for time calculation. This variable, however, isn't defined anywhere in ui/gtk.c and instead ui/console.c just sets it to GUI_REFRESH_INTERVAL_DEFAULT which is 30 update_interval represents the number of milliseconds per display refresh, and by doing some math we get that 1000/30 = 33.33... Hz This creates the mentioned problem and what this patch does is that it checks for the display refresh rate reported by GTK itself (we can take this as a safe value) and just converts it back to a number of milliseconds per display refresh.
