--Can any one explain or point me to an information source that explains what "realtime linux" is.
--What would be the difference between "realtime linux" and an application
that runs in user space?
In summary, 'realtime linux" means providing a way for some kind of task (perhaps in user space, perhaps
limited to kernel space) to get better (hopefully truly deterministic) response time to an event such as
an interrupt. A standard Linux kernel, 2.6 kernels included, even with preemption configured on, can not
provide guaranteed response time.
Here is a link to the 3rd of my 3 article series about real-time Linux that appeared in Embedded Linux
Journal. This article links to the first two articles.
I hope they help.
