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?
