What is Trinity2?#

Trinity2 is an internal code name for the next release from the OS-kernel team. It consists of three parts:

1. Neutrino Core OS 6.4.0
2. Adaptive Partitioning TDK (now part of the Advanced Runtime Module)
3. Multi-Core TDK (now part of the Advanced Runtime Module)

All three are intricately linked to OS-kernel development and all three will receive updates as part of Trinity2.

• POSIX PSE52 Certification
• ARM 11/ARMv6 architectures support
• Improved performance
  • Variable Page Size
  • Wired TLB
  • Cached confstr() values
  • PPCBE BAT Addressing

• Memory Partitioning (available with the Advanced Runtime Module)

Milestone Builds for Trinity2:#

The following are experimental milestone builds for Trinity 2. Each build is an early version snapshot of the OS. Trinity 2 will be included in the next full product release, howevever, to try it out, simply install over top of Momentics 6.3.2 (installation instructions are provided).

Each build is tested by the test team at QNX to identify issues. Fixes are added to each subsequent build. A readme for each milestone build is available that includes major Known Issues, What’s Fixed, and What’s New.

If you discover any problems please let us know via the forum. There will be a new milestone build posted roughly once a month until release.

What can I do?#

Feature development for Trinity2 is now frozen but that shouldn’t stop you from getting involved. We’re still testing, fixing, optimizing, and solidifying. Take a look through the code or download the latest build and try it out. If you have any comments or spot a bug, bring it to the attention of the team through the forums.
