“FSMLabs has announced the release of RTLinux V3.0 hard realtime
Linux to developer beta status. RTLinux features a POSIX
1003.13 API, hard real-time functionality, and the ability to take
full advantage of the Linux kernel (which runs under RTLinux
as a non real-time thread). RTLinux V3 currently supports Intel
x86, Alpha, and PowerPC processors. SMP is supported on x86.”
