rhi: Drop the profiler for now The system we inherited from the original Qt 5.14 introduction of QRhi is a text stream based solution where resource creation and frame timings are sent in a comma-separated format to a QIODevice. This, while useful to get insights about the number of resources at a given time, is not actively helpful. The frameworks built on top (Qt Quick, Qt Quick 3D) are expected to provide solutions for logging timings in a different way (e.g. via the QML Profiler). Similarly, tracking active resources and generating statistics from that is better handled on a higher level. The unique bits, such as the Vulkan memory allocator statistics and the GPU frame timestamps, are converted into APIs in QRhi. This way a user of QRhi can query it at any time and do whatever it sees fit with the data. When it comes to the GPU timestamps, that has a somewhat limited value due to the heavy asynchronousness, hence the callback based API. Nonetheless, this is still useful since it is the only means of reporting some frame timing data (an approx. elapsed milliseconds for a frame) from the GPU side.

rhi: Enhance line width and point size support ...but this will vary between backends, or in some cases even between implementations of the same API. Point size is settable only via the vertex shader (gl_PointSize). It is silently ignored with D3D and HLSL. Line widths other than 1 are supported only on OpenGL and Vulkan. (but this is in fact deprecated with GL and optional with Vulkan) Add QRhi::Feature values for both. The line width is now settable on QRhiGraphicsPipeline. It is not a dynamic state since the static, per-pipeline width is good enough for most cases. (and the feature is not supported on half of the backends anyways so it will get limited use in practice).

rhi: Pipeline cache load/save 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.
