Graphics improvements for Embedded Linux in Qt 5.7

By Laszlo Agocs

As is the tradition around Qt releases, it is now time to take a look at what is new on the Embedded Linux graphics front in Qt 5.7.

NVIDIA DRIVE CX

The linux-drive-cx-g++ device spec introduces support for the NVIDIA DRIVE CX platform. This is especially interesting for the automotive world and is one of the foundations of Qt’s automotive offering. Also, DRIVE CX is in fact the first fully supported embedded system with a 64-bit ARM architecture (AArch64). When it comes to graphics, the core enablers for the eglfs and wayland platform plugins were mostly in place for Qt 5.6 since the stack is very similar to what we had on the previous generation Jetson Pro systems. There are nonetheless a number of notable improvements in Qt 5.7:

  • The JIT is now enabled in the QML JavaScript engine for 64-bit ARM platforms. In previous releases this was disabled due to not having had received sufficient testing. Note that the JIT continues to stay disabled on mobile platforms like iOS due to app store requirements.
  • eglfs, the platform plugin to run OpenGL applications without a windowing system, has improved its backend that provides support for setting up EGL and OpenGL via DRM and the EGLDevice/EGLOutput/EGLStream extensions. The code for handling outputs is now unified with the GBM-based DRM backend (that is typically used on platforms using Mesa), which means that multiple screens are now supported on the NVIDIA systems as well. See the documentation for embedded for more information.
  • When it comes to creating systems with multiple GUI processes and a dedicated compositor application based on Wayland, QtWayland improves a lot. In Qt 5.6 the NVIDIA-specific support was limited to C++-based compositors and the old, unofficial compositor API. This limitation is removed in 5.7, introducing the possibility of creating compositor applications with QML and Qt Quick using the modern, more powerful compositor API which is provided as a technology preview in Qt 5.7.

    One notable limitation for Qt Quick-based compositors (with no serious consequences in practice) on the DRIVE CX is the requirement for using a single-threaded render loop. The default threaded one is fine for applications, but the compositor process requires to be launched with the environment variable QSG_RENDER_LOOP=basic (or windows) for the time being. This may be lifted in future releases.

  • If Qt-based compositors are not desired, Qt applications continue to function well as clients to …read more
