2021-03-04configure: Improve OpenGL dependency detectionsAkihiko Odaki1-3/+3
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 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.

2021-01-15ui/gtk: update monitor interval on egl displaysNikola Pavlica1-0/+3
When running QEMU's GTK UI without EGL or OGL, the gd_monitor_update_interval function gets executed and the display refresh rate gets updated accordingly. However, when using EGL or just regular OGL, the function never gets executed. Which is why I decided that the function should be in gd_egl_refresh where the display output gets updated, in the same vain as how it's done for normal GTK UIs (aka. those without EGL) - in it's display refresh function. Since the gd_monitor_update_interval function now is exposed, we are going to use it to update the refresh rate.

2018-10-12ui: remove support for GTK2 in favour of GTK3Daniel P. Berrangé1-6/+4
GTK2 was deprecated in the 2.12.0 release with: commit b7715af2b31f47060cc5b4be930d16c13be93fa9 Author: Daniel P. Berrange <berrange@redhat.com> Date: Tue Dec 12 11:34:40 2017 +0000 ui: deprecate use of GTK 2.x in favour of 3.x series The GTK 3.0 release was made in Feb, 2011: https://blog.gtk.org/2011/02/10/gtk-3-0-released/ That will soon be 7 years ago, which is enough time to consider the 3.x series widely supported. Thus we deprecate the GTK 2.x support, which will allow us to delete it in the last release of 2018. By this time, GTK 3.x will be almost 8 years old. Signed-off-by: Daniel P.

Add support for OpenGL ES to egl-helpers. Wire up the new option for egl-headless and gtk UIs. egl-headless actually works fine. gtk hits a not-yet implemented code path in libEGL when trying to use gles mode: libEGL warning: FIXME: egl/x11 doesn't support front buffer rendering.

This adds opengl rendering support to the gtk ui, using egl. It's off by default for now, use 'qemu -display gtk,gl=on' to play with this. Note that gtk got native opengl support with release 3.16. There most likely will be a separate implementation for 3.16+, using the native gtk opengl support. This patch covers older versions (and for the time being 3.16 too, hopefully without rendering quirks). Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
