Supported Development Environment

Supported Qt and Qt Tools Versions

Qt Safe Renderer 2.1.0 RC 2 installation provides pre-built binaries for Qt 6.5.6. If you like to use Qt Safe Renderer 2.1.0 RC 2 with some later Qt version, you need to build Qt Safe Renderer from source. For more information, see Building Qt Safe Renderer.

The safe QML types included in Qt Safe Renderer (see Qt Safe Renderer QML Types) and the related layout data format are supported in Qt Creator 10.0.x and later.

Qt Safe Renderer 2.1.0 RC 2 supports developing UI with Qt Design Studio 4.2 and later. With Qt Design Studio, you can develop a UI with QML types.

Note: Qt Designer supports developing UI only with Qt Widgets. Thus you cannot develop the safety-critical UI with Qt Designer. Also, Qt Quick Designer included in Qt Creator is not supported.

Supported Adaptations

Qt Safe Renderer 2.1.0 RC 2 provides several adaptations: reference adaptations, techonology preview adaptations, and host adaptations. All reference adaptations are MISRA-compliant. Use the host adaptations only for development purposes.

Note: It is easy to adapt Qt Safe Renderer also for other environments.

Reference Adaptations

The Qt Safe Renderer 2.1.0 RC 2 reference adaptations are as follows:

Adaptation group	Provided adaptations	MISRA compliance
Graphics backends adaptations	drm for Linux qnxscreen for QNX 7.1 OpenWF platform adaptation for QNX and INTEGRITY	Yes Yes Yes
Event handler adaptations	The Posix message queue The QNX message queue The INTEGRITY message queue	Yes Yes Yes
Output verifier adaptations	Qualcomm Snapdragon adaptation integrates with the OpenWF graphics adaptation.	Yes

You find the sources for adaptations under <QSR Installation directory>/Src/QtSafeRenderer-runtime-<version>/src/adaptation.

Technology Preview Adaptations

Qt Safe Renderer provides the following technology preview adaptations. By default, the technology preview adaptations are not MISRA-compliant.

Adaptation group	Provided adaptations	MISRA compliance
Graphics backends adaptations	rcar3 that can be used on Renesas R-CarD3. It supports the Renesas window manager.	No
Output verifier adaptations	NXP i.MX 8 monitor for Boot to Qt 6.5 for Embedded linux	Yes

You find the sources for adaptations under <QSR Installation directory>/Src/QtSafeRenderer-runtime-<version>/src/adaptation.

Host Adaptations

Qt Safe Renderer provides the following host adaptations for development usage. These adaptations are not MISRA-compliant and they support only C++17. The host adaptations are not part of the certified Qt Safe Renderer code.

Adaptation group	Provided adaptations	MISRA compliance
Graphics backends adaptations	qtqui that uses Qt's graphics adaptation. It's aimed at running the Qt Safe Renderer runtime component on the host environment.	No
Event handler adaptations	qtnetwork that uses the Qt Network module	No
Output verifier adaptations	Qt GUI adaptation that is integrated with QWindow. With the adaptation, you can test the output verifier in the host environment.	No

You find the sources for adaptations under <QSR Installation directory>/Src/QtSafeRenderer-runtime-<version>/src/adaptation.

Supported Host Platforms

Qt Safe Renderer related development work is done on a host platform. The following host platforms are supported in Qt Safe Renderer 2.1.0 RC 2. The listed compilers are used in Qt Safe Renderer testing but other compiler versions may also work.

Operating System	Architecture	Compiler	Supported Qt Version
Ubuntu 22.04	x86_64	GCC 11.x	Qt 6.5.x (latest version)
Windows 11	x86_64	MSVC 2022, MinGW 11.2	Qt 6.5.x (latest version)
macOS 12.0	x86_64	Xcode 13 (13 SDK)	Qt 6.5.x (latest version)

Reference Target Devices

Qt Safe Renderer can be used with a wide range of target devices and operating systems.

The target device must support hardware layers because Qt Safe Renderer is the overlay on top of the non-safe UI.

The operating system of the embedded platform must fulfill the following requirements:

Provides a way to set up the graphics overlays.
Supports multiple processes and memory protection between the processes. For example, QNX has a microkernel architecture that prevents processes from interfering with each other. On hypervisor architectures, the non-safe main UI can run on the virtual operating system while the safety-critical content is rendered in the real-time operating system.
All the tools that are part of producing the Qt Safe Renderer runtime binary must be certified according to the application target safety integrity level (SIL or ASIL) based on the appropriate functional safety standard.

The Qt Safe Renderer 2.1.0 RC 2 functionality has been tested with the following reference hardware configurations:

NXP i.MX 8 for Boot to Qt 6.5 for Embedded Linux
Qualcomm Snapdragon SA8295P with QNX 7.1
Qualcomm Snapdragon SA8155P with INTEGRITY 19.0.14

If you are our commercial customer, and you want to suggest a change in the existing functionality or report a Qt bug concerning some supported target device or host platform, we recommend you to contact our support team. For more information, see Qt Support. Qt Professional Services can help you with the bugs and suggestions that concern some non-supported target device or host platform.

Coding Standards

Qt Safe Renderer Runtime components support C++98 coding standard. Qt Safe Renderer tools support C++17 coding standard. For more information, see https://isocpp.org/std/the-standard.

Qt Safe Renderer Runtime coding follows MISRA C++ 2008 Guidelines. Qt Safe Renderer Monitor coding follows MISRA C 2004 Guidelines.
