* Port from qAsConst() to std::as_const()Marc Mutz2022-10-111-1/+1
| | | | | | | | | | | | | | | | We've been requiring C++17 since Qt 6.0, and our qAsConst use finally starts to bother us (QTBUG-99313), so time to port away from it now. Since qAsConst has exactly the same semantics as std::as_const (down to rvalue treatment, constexpr'ness and noexcept'ness), there's really nothing more to it than a global search-and-replace, with manual unstaging of the actual definition and documentation in dist/, src/corelib/doc/ and src/corelib/global/.

* eglfs: Add env.var. to disable the dedicated drmHandleEvent threadLaszlo Agocs2022-09-221-6/+0
| | | | | | | | | | | | | | | | | | | | Setting QT_QPA_EGLFS_KMS_NO_EVENT_READER_THREAD=1 makes it operate like it did before 5.12.7: just calling drmhandleEvent (guarded by a mutex) on the current (main or render, depending on the QQ render loop) thread. This should not be needed and is discouraged (will certainly cause deadlocks in multiscreen setups + QQ threaded render loop on certain embedded systems), but it seems necessary to provide a way to revert back to the old way of functioning as there are reports about problems with screen cloning when the dedicated event reading thread is used.

* Add a way to declare _exported_ logging categoriesGiuseppe D'Angelo2022-06-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a library declares a logging category that needs to be used by clients (e.g. via inline methods, macros, etc.), then the logging category function generated by Q_DECLARE_LOGGING_CATEGORY has to be exported. We've seen this problem with Q_NAMESPACE, Q_GADGET, etc.: these macros also declare functions or objects that in some cases need to be exported. And precisely like Q_NAMESPACE, Q_GADGET, etc., people end up relying on the implementation details of Q_DECLARE_LOGGING_CATEGORY (specifically, what does it expand to) in order to place the export directives in the right place. Introduce a more robust solution and apply it around qtbase. Cleanup some minor code as a drive-by (remove `extern` and useless semicolons). [ChangeLog][QtCore][QLoggingCategory] Added the Q_DECLARE_EXPORTED_LOGGING_CATEGORY macro, in order to allow dynamic libraries to declare a logging category that can be then used by client code.

This could be seen with the threaded render loop of Qt Quick: having a QQuickWindow per screen means having a dedicated render thread for each screen. QKmsDevice used simply instance variables to keep track of the request. This leads to the commit failing with EBUSY sooner or later. Make the atomic request and related variables thread local. This prevents failing drmModeAtomicCommit() with 2 or more screens and the threaded render loop. It does not fix other potential issues when waiting for page flips to complete, that is to be tackled separately.

This is done by setting the INTERFACE_QT_PACKAGE_NAME and INTERFACE_QT_PACKAGE_VERSION properties on the imported targets. This information allows us to generate appropriate find_dependency() calls in a module's Config file for third party libraries. For example when an application links against QtCore, it should also link against zlib and atomic libraries. In order to do that, the library locations first have to be found by CMake. This is achieved by embedding find_dependency(ZLIB) and find_dependency(Atomic) in Qt5CoreDependencies.cmake which is included by Qt5CoreConfig.cmake. The latter is picked up when an application project contains find_package(Qt5Core), and thus all linking dependencies are resolved. The information 'which package provides which targets' is contained in the python json2cmake conversion script. The generated output of the script contains qt_find_package() calls that represent that information. The Qt5CoreDependencies.cmake file and which which dependencies it contains is generated at the QtPostProcess stop. Note that for non-static Qt builds, we only need to propagate public 3rd party libraries. For static builds, we need all third party libraries. In order for the INTERFACE_QT_PACKAGE_NAME property to be read in any scope, the targets on which the property is set, have to be GLOBAL. Also for applications and other modules to find all required third party libraries, we have to install all our custom Find modules, and make sure they define INTERFACE IMPORTED libraries, and not just IMPORTED libraries.

| | | | | | | | | | | | | | | | | | | | | | | | | | This commit will add the possibility to have a different sizes between framebuffer and videomode using DRM atomic, which is not possible with DRM legacy. The main goal of this change is to allow to get decent performance on embedded devices which can support high resolution display (ie UHD), and which don't have a GPU able to achieve decent framerate in such resolutions. This patch adds a "size" member to the output configuration in KMS configuration file. The GBM framebuffer will be created with that size and the GBM screen will report that size so that EGLFS can do everything normally. Scaling planes with different size than the video mode size is not something supported consistently with DRM legacy, so that feature will be only available when using the DRM atomic API. This was tested on Rock64 device, both with drm legacy and atomic.

* Add a tech preview eglfs device integration for VSP2 compositionJohan Klokkhammer Helsing2018-01-082-1/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This creates a new device integration for eglfs, eglfs_kms_vsp2, that's very similar to eglfs_kms_gbm, but includes an extra step for doing VSP2 hardware compositing. The main Qt content is drawn to double buffered off-screen GBM buffers which are converted using drmPrimeHandleToFD so we get DMA buffer file descriptors that can be used by the VSP2 blending hardware. The blending hardware writes to double buffered DRM dumb buffers, which are flipped with drmModePageFlip. Communicating with the VSP2 is done using the Video4Linux2 (V4L2) streaming API. There are two steps in creating abstractions for this. First, there is the QLinuxMedia class that consists of a Qt style wrapper for V4L2 without anything VSP2 specific. Second, there is QVsp2BlendingDevice which hides some of the streaming details of the VSP2 and has some level of error recovery. Both classes include a fair bit of logging and error reporting. The patch is written with Wayland compositors in mind, but should work for other use cases as well. This is just the basic support to make compositing work, additional features may be added in subsequent patches, i.e: - Auto-detect VSP2 (-feature-vsp2 currently needs to be explicitly enabled). - Support for setting the alpha value of a layer. - Support clipping layers. - Support for scaling layers. - Support for other output formats than RGBA32. - Hardware cursor support. - Support foreign layers below the main Qt layer. - Support for memory mapped and user pointer buffer types (currently only DMA buffers are supported).

* eglfs_kms: Add headless mode for DRM render nodesLaszlo Agocs2017-09-052-3/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Attempting to switch /dev/dri/cardX to /dev/dri/renderDY is futile on its own now since many output-related drm operations fail and we eventually crash. Add a new headless mode that skips the real screen stuff and registers a fairly dummy, headless screen, does not bother with the mouse cursor, and disallows rendering to the screen via a QWindow (while keeping the actual rendering still fully functional). Such applications will not need any special privileges and will run even if there is a DRM master (X11, Wayland compositor) active. For example the configuration can look like this: { "device": "/dev/dri/renderD128", "headless": "1024x768" } After this applications have two choices to perform offscreen rendering: 1. Use an ordinary window (and its default framebuffer, meaning the gbm_surface), e.g. a QOpenGLWindow subclass MyOpenGLWindow w; w.show(); // will not actually show on screen w.grabFramebuffer().save("output.png"); Note that there is no vsync-based throttling. Also note that windows are still sized to match the screen size, hence the need for specifying a size in the headless property. 2. Or the typical offscreen approach with an extra FBO QOffscreenSurface s; s.setFormat(ctx.format()); s.create(); ctx.makeCurrent(&s0; QOpenGLFramebufferObject fbo(1024, 768); fbo.bind(); ctx.functions()->glClearColor(1, 0, 0, 1); ctx.functions()->glClear(GL_COLOR_BUFFER_BIT); fbo.toImage().save("output.png"); ctx.doneCurrent(); Task-number: QTBUG-62262 Change-Id: Ic1dbfa2b27b223bd5ef8ba36b665f0f61abf4f06 Reviewed-by: Qt CI Bot <qt_ci_bot@qt-project.org> Reviewed-by: Andy Nichols <andy.nichols@qt.io>
* eglfs_kms: Add support for formats other than XRGB8888Laszlo Agocs2017-09-051-3/+21
| | | | | | | | | | | | | | | | | | Switch to drmModeAddFB2 and add mappings for RGB565 and ARGB8888, and some BGR variants. The default is XRGB8888, like before. Others can be requested in the config file with "format": "rgb565" or "argb8888" etc. on a per-output basis. If the primary plane does not support the format, modesetting and flipping will fail.
