"realtime" linux

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?

"First Word from the Hearing: It's IBM All the Way
Thursday, November 30 2006  <at>  08:11 PM EST

I've gotten two reports from today's hearing in SCO v. IBM now, from
new folks who haven't reported in the past from hearings, so I waited
until there were two of them, and they both say the same thing: It went
very well. Magistrate Judge Brooke Wells ruled from the bench in favor
of IBM. SCO will not be allowed to, as IBM put it in its motion papers,
"litigate this case by ambush." "

Looks like the "ride" is gonna get a lot steeper!

info about realtime Linux

Denis,

--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.

Being "real time" means that an application can guarantee that it will
respond within a small fixed time usually measured in units less than or
equal to a millisecond. Real time Linux is a Linux kernel with the
ability to schedule applications on a real time basis. 

So, real time linux is a kernel that can run both real time and non real
time applications in user space.

There have been many versions of real time linux kernels available from
third parties for quite some time, real time extensions were accepted
into the main kernel source tree for version 2.6.18 giving the default
kernel real time abilities. You might want to start looking here

zdnet in australia has turned into full time bootlicking shill of ms
over the past year or so, ever since they got a new editor in chief.

This has got to be the most ridiculous post I have ever seen on this
list. The temperature was only in the 30's.
