2022-06-14ui: Deliver refresh rate via QemuUIInfoAkihiko Odaki1-2/+1
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 Rümelin1-1/+30
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.

An example for this is the Intel i965 driver on a Haswell processor.

2021-12-21ui: simplify gl unblock & flushMarc-André Lureau1-2/+0
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.

2021-11-02ui/gtk: Update the refresh rate for gl-area tooNikola Pavlica1-0/+3
This is a bugfix that stretches all the way back to January 2020, where I initially introduced this problem and potential solutions. A quick recap of the issue: QEMU did not sync up with the monitors refresh rate causing the VM to render frames that were NOT displayed to the user. That "fix" allowed QEMU to obtain the screen refreshrate information from the system using GDK API's and was for GTK only. Well, I'm back with the same issue again. But this time on Wayland. And I did NOT realize there was YET another screen refresh rate function, this time for Wayland specifically. Thankfully the fix was simple and without much hassle. Thanks, Nikola PS: It seems that my patch has gone missing from the mailing list, hence I'm sending it again. Sorry for any inconveniences.

2021-03-04configure: Improve OpenGL dependency detectionsAkihiko Odaki1-1/+1
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.

2021-02-19ui/console: Remove dpy_gl_ctx_get_currentAkihiko Odaki1-5/+0
It is not used, and it is unlikely that a new use case will emerge anytime soon because the scope of OpenGL contexts are limited due to the nature of the frontend, VirGL, processing simple commands from the guest. Remove the function and ease implementing a new OpenGL backend a little.

2021-02-04display/ui: add a callback to indicate GL state is flushedMarc-André Lureau1-0/+3
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.
