QNX Platform Overview

The QNX Software Development Platform (SDP) is a comprehensive suite of tools and run-time microkernel operating systems designed for embedded, safety-critical, and real-time applications. Current versions include QNX SDP 8.0 and QNX SDP 7.1. QNX SDP empowers developers with a modular, POSIX-compatible RTOS (QNX Neutrino), a full-featured IDE (QNX Momentics), specialized safety-certified variants (QNX OS for Safety), virtualization support (QNX Hypervisor and QNX Hypervisor for Safety), and emerging capabilities such as containerization (QNX Containers) and cloud-enabled development (QNX Accelerate). QNX’s microkernel architecture delivers deterministic, secure, and scalable foundations for IoT, automotive, industrial control, medical, and more.

QNX Software Development Platform (SDP) 8.0 and 7.1

QNX SDP 8.0

Release Date: May 2024 (8.0.1 update August 2024)
Key Enhancements:

Virtual Memory Manager Revised (VMM) for higher throughput when allocating large memory blocks (e.g., process creation).
“Stable” promotion of previously experimental features: dynamic processor state management (SCHED_PROCESSOR_ONLINE/OFFLINE), an enhanced High Availability Manager (HAM), and ARMv8 SMMU (System Memory Management Unit).
Updated IDE User’s Guide: new topics on event formatting, interrupt handling, and scheduler callouts.

Components:

QNX Neutrino RTOS 8.0 (microkernel, libc, drivers, networking, file systems)
QNX Momentics Tool Suite 8.0(Eclipse-based IDE, compilers, debuggers, system profiler)
QNX Hypervisor 8.0 (microkernel hypervisor supporting ARM and x86 guests, VIRTIO device sharing)
QNX Containers(OCI- and Kubernetes-compliant container runtime on QNX 8.0)
QNX OS for Safety 8.0 (pre-certified OS to ISO 26262 ASIL D, IEC 61508 SIL 3, IEC 62304 Class C)
Specialized SDKs: QNX Sound, QNX Platform for ADAS, QNX Platform for Instrument Clusters, etc.

Licensing: Offered as Named-User, Build-Server, and Floating-User perpetual/subscription models.

QNX SDP 7.1

Release Date: March 2024
Legacy Support: Still widely deployed in automotive, industrial, medical, and IoT systems.
Components: Microkernel, libc, QNX Momentics 7.1, QNX Hypervisor 2.2, QNX OS for Safety 2.2, QNX Filesystem for Safety 1.0, ADAS Platform 1.x, Acoustics Management Platform 3.2.
Service Packs & Updates: Ongoing 7.1.x updates for critical fixes and incremental features.

Why QNX?

Determinism & Real-Time Responsiveness

Microkernel architecture provides sub-microsecond context switches, ensuring hard real-time deadlines under high load.
Proven jitter control: jitter < 1 µs in many benchmarks.

Scalability & Modularity

Scales from small microcontrollers (ARM Cortex-M) to multicore automotive SoCs (NXP S32V, Renesas H3, Intel Apollo Lake).
Adaptive partitioning ensures CPU bandwidth guaranteed for safety-critical tasks.

Cloud-Enabled Development

QNX Accelerate: spin up QNX RTOS target images as AWS/Azure AMIs for CI/CD, collaboration, and scalable testing.

Security & Safety by Design

Layered security (SELinux-style policies, capabilities, encrypted file systems, TPM support).
Pre-certified safety variants (ISO 26262 ASIL D, IEC 61508 SIL 3) minimize certification effort.
QNX Hypervisor for Safety allows isolation of safety-critical and general-purpose OSs on a single SoC.

Broad Ecosystem & Tooling

QNX Momentics IDE integrates seamlessly with LDRA, Vector, and Wind River for static analysis, profiling, and compliance.
Extensive Board Support Packages (BSPs) for development kits, evaluation boards, and custom hardware.
