What features do real time OS's such as VxWorks have that Linux doesn't?
A guy at work commented that VxWorks has functions to enable or disable caching of memory ranges and Linux would need similar functions to compete in our moderatly real time (10-30ms) applications. I've seen the recent patches for MTRR on the intel processors, which sounds similar to what he wants.
But why intel unique? Does Linux control caching in a cross-platform portable way?
Does VxWorks really have something better or does Linux implement a different but useful approach?
