What is the state of documentation on QNX? Is there sufficient documentation that it would be possible to write a QNX-compatible kernel from the documentation (plus access to a QNX machine, which has to be available somehow outside of industry, right?)?
- Animats 8y agoUntil Blackberry bought it, it was open source. There were free downloads. Now it's proprietary. But there's a lot of info out there from the open source era. The manuals are available. Here's the original QNX paper.[1] [1] https://cseweb.ucsd.edu/~voelker/cse221/papers/qnx-paper92.pdf https://cseweb.ucsd.edu/~voelker/cse221/papers/qnx-paper92.p...

- Animats 8y agoHere's the 2007 press release announcing QNX going open source.[1] On April 9, 2010, the day the acquisition closed, Research and Motion took the source code offline, with no notice. All user open source projects on QNX were abandoned shortly thereafter.[2] [1] http://www.qnx.com/news/pr_2471_1.html http://www.qnx.com/news/pr_2471_1.html [2] https://community.qnx.com/sf/sfmain/do/listProjects https://community.qnx.com/sf/sfmain/do/listProjects
