Hi list, I am trying to figure out why Linux is not a real time OS, which i believe is true but want to know which part of the OS introduces nondeterministics. I try to start with the implementation of spin_lock family, but it seems that interrupt has been disabled and nothing can interfare. also the interrupt service routine is said to suffer from delays, but as a newbie I feel no place to start with. Any hints, links or ideas that can shed some light on this issue will be highly appreciated. with kind regards, Yang -- Kernelnewbies: Help each other learn about the Linux kernel.
