Little of IRIX's RT capabilities have to do with smart hardware. They offer POSIX RT stuff similar to Linux, RT file I/O on RT subvolumes of XFS filesystems and sysmp(2) which allows to assign cpu(s) exclusivly to certain processes, disable interrupt processing on them etc. such that they are exclusivly running the application process. Actually the latter is a solution which is suprisingly effective for relativly small cost; it may be favourable for many cases to have something like this in Linux and not RT-Linux.
