* QEglPlatformContext: Also check for GL_EXT_ROBUSTNESSDavid Redondo9 days1-1/+14
| | | | | | | | | | | | | EGL_EXT_create_context_robustness says that on GLES GL_EXT_robustness is required - indeed the nvidia driver only exposes the EXT variant on GLES. Without this a context with reset notification is created but it's not reported via its format, this has impact when further contexts sharing with it are created which need to match its robustness.

* Support graphics reset notifications on EGLDavid Edmundson2025-09-172-51/+200
| | | | | | | | | | | | | | | If a GPU hangs or is reset, this flag ensures the application is notified with a context loss event. This can then be queried by platforms to make use of Qt's existing reset handling. This is opt-in by applications based on the ResetNotification flag on the requested format. If a robust context cannot be created, it falls back to trying without this flag and the state is reflected in the retrieved surfaceFormat matching the behavior of GLX.

* EGL: undef X11 macrosGiuseppe D'Angelo2025-05-301-0/+14
| | | | | | | | | | | Including egl.h may transitively include X headers which define a bunch of macros that clash against our code. Undef these macros just after EGL is included. This was already done locally in eglfs, but the same problem appears in any code that uses qt_egl_p.h, like the Wayland platform plugin.

* Add support for using static EGL libraries on VxWorksKarim Pinter2025-03-181-1/+1
| | | | | | | | | | | | | | | On VxWorks there is dlopen, but the feature can be turned off for static builds, so Qt can use EGL even when dlopen is not present. In qeglplatformcontext.cpp dlsym needs dlopen feature. There is no dlopen on windows neither on Integrity.

* Clear VxWorks MESA display artifacts on startupMichał Łoś2024-10-151-0/+15
| | | | | | | | | | | | | | | | | | | | | This cherry-pick is a preparatory change as eglfs is not yet enabled on Intel VxWorks. Cherry-picked commit e39f3ebba61acddea2e6dfe6e9506ce0441bfd8b Author: Cliff Bilbrey <cliff.bilbrey@qt.io> Date: Fri Jun 9 13:56:14 2023 -0500 Display artifacts are sometimes seen at startup in VxWorks applications that make use of the MESA OpenGL libraries. This issue has been demonstrated in the Wind River MESA OpenGL demos, which use the same technique incorporated here to mask the problem. Cyling through the complete set of framebuffers and clearing each during the initialization process creates a clean slate that prevents the artifacts from being noticeable to the end user.

| | | | | | | | | | | | | Found some documentation saying NVidia provided desktop GL for development purposes only, and recommmended against using it. Not sure if that applied to all NVidia drivers, or only that one embedded platform, but since we have multiple bugs about EGL not working on NVidia, default to using GLES2 like it suggested.

* Add QEGLContext::invalidateContextThomas Senyk2023-01-121-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | QEGLContext::invalidateContext will mark that egl context is invalide and trigger SceneGraph to destroy it, create a new one and re-create and re-upload all resources (e.g. textures) associated with the current state of the SceneGraph In addition this change also improves QEglFSWindow::invalidateSurface() and QEglFSContext::eglSurfaceForPlatformSurface(..) Where QEglFSWindow::invalidateSurface() will now destroy the corresponding EGLSurface via eglDestroySurface, including "unbinding" it from the current thread via eglMakeCurrent and un-setting the screen's EGLSurface in case it's the same resource. QEglFSContext::eglSurfaceForPlatformSurface(..) will now call QEglFSWindow::resetSurface() in case of getting a EGL_NO_SURFACE from the QEglFSWindow (which happens if above invalidateSurface() was called before) - therefor re-creating the resource if it was destoyed via QEglFSWindow::invalidateSurface() Pick-to: 6.5 Change-Id: I37badd1fc11e993c395fb1502e9bd27ebe18b821 Reviewed-by: Laszlo Agocs <laszlo.agocs@qt.io>
* qputenv: port to QByteArrayViewMarc Mutz2022-08-061-1/+1
| | | | | | | | | | | | | | | | | | | | The vast majority of in-tree users pass simple and short C string literals as the value. By porting to QByteArrayView, we document that we'll accept non-NUL-terminated data, and do the NUL-termination internally, using SSO'ed std::string, saving memory allocations in the common case of short strings. I didn't bother to check which direction std::string takes for nullptrs these days (there was a change accepted in that area for C++20 or 23), so play it safe and protect against them.
