* rhi: Pipeline cache load/saveLaszlo Agocs2021-01-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add QRhi APIs to retrieve and reload the contents of the "pipeline cache". The only API where there is a true pipeline cache is object is Vulkan (VkPipelineCache). For OpenGL, the other backend where we support this, it is simulated with program binaries. The Qt 5 style OpenGL program binary disk cache continues to work like before, but one has now the option to do things in a more modern, graphics API agnostic way, that leads to generating a single blob instead of a large set of files in some system location, allowing easier "pre-baking" of the cache content. It is expected that Qt Quick exposes the two new functions in form if QSG_RHI_ environment variables, thus allowing easy testing and cache file generation. As an example for the performance improvements this can give, consider Vulkan, where we do not have any existing persistent caching mechanism in place: Running BenchmarkDemoQt6.exe --scene flythrough --mode demo creates 18 QRhiGraphicsPipeline objects from Qt Quick and Qt Quick 3D. The total time spent in QRhiGraphicsPipeline::create() during application startup for these 18 pipelines is 35-40 ms on a given Windows (NVIDIA) system. When exporting the pipeline cache contents to a file, and then, in a subsequent run, reloading the cache contents, this is reduced to 5-7 ms on the same system, meaning we get a 6-7x improvement. The generated data is always specific to a given Qt version, RHI backend, graphics device, and driver version. Much of the implementation consists of adding and verifying the appropriate header to the blobs retrieved from the driver, to allow gracefully ignoring data that was generated with a device or driver that differs from the one used at run time. This should provide robustness, even if the Vulkan or OpenGL implementation is for some reason not prepared to identity and reject incompatible cache/program blobs.

* Add a dedicated QWindow surface type for D3DLaszlo Agocs2021-01-044-8/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Even though there is no D3D-specific logic in the windows platform plugin, meaning a QWindow with either OpenGLSurface or VulkanSurface (or anything really) is DXGI/D3D-compatible, it now looks like it is beneficial, and more future proof, if there is a dedicated surface type. As the linked report shows, there are OpenGL-specific workarounds accumulated in the platform plugin, while not being clear if these are relevant to non-OpenGL content, or if they are relevant at all still. (and some of these can be difficult/impossible to retest and verify in practice) When D3D-based windows use the same surface type, all these are active for those windows as well, while Vulkan-based windows have their own type and so some of these old workarounds are not active for those. To reduce confusion, having a dedicated surface type for D3D as well allows the logic to skip the old OpenGL workarounds, giving us (and users) a more clear overall behavior when it comes to OpenGL vs. Vulkan vs. D3D. The change is compatible with any existing code in other modules because any code that uses OpenGLSurface for D3D will continue to work, using the new type can be introduced incrementally.

| | | | | | | | | | | | | | | | | The original restriction to UniformBuffer was due to the GL backend where there is no GL buffer object for QRhiBuffers with usage UniformBuffer. However, we can still implement this for cases when there is a true GL buffer object underneath. With other backends it should all work as-is already. This becomes useful when one has buffers with usage Vertex that need full updates every frame. (f.ex. instance data) Unfortunately this involves renaming the function. But while at it, add an autotest case as well. Change-Id: Iff59e4509a8bae06654cc92fe8428bd79eb012fb Reviewed-by: Andy Nichols <andy.nichols@qt.io>

This aligns the behavior of synthetic quits via QCoreApplication::quit() with spontaneous quits from the platform via QGuiApplicationPrivate::processApplicationTermination. Clients who wish to exit the application without any event delivery or potential user interaction can call the lower level exit() function directly.

| | | | | | | | | | | | | | | | | | Follows the QWindow semantics, and is a replacement for creating a QWidget with a QDesktopScreenWidget as the parent. We can now remove much of the special handling of QDesktopWidget and the Qt::Desktop window type, and get rid of QDesktopScreenWidget. Add a manual test that allows local testing. Our CI environments only have a single screen, and no multi-head display server setup which is the primary case where QWidget::setScreen is interesting. For the more common case of a virtual desktop, QWidget::setScreen has no real impact (just as QWindow::setScreen doesn't).

* Make QFontDatabase member functions staticEskil Abrahamsen Blomfeldt2020-08-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | QFontDatabase is a singleton and all instances would share a single, mutex-protected global data pointer. But some functions were implemented as non-static functions. This caused a lot of code on the form QFontDatabase().families(...) since there was no static access. Other functions were implemented as static. To consolidate, we make all functions static. This should be source-compatible, but not binary compatible. [ChangeLog][QtGui][Fonts] Some functions in QFontDatabase were in principle static, but previously not implemented as such. All member functions have now been made static, so that constructing objects of QFontDatabase is no longer necessary to access certain functionality.
