Whoops. In that case this is an interesting product to me.

Eh the RT Linux patches are soft real time at best. It's sort of the "I guess you tried, bless your heart" level of real time guarantees.

The patches are adding higher nice values, and trying to remove some of the egregious kernel contention.

That's the Linux RT patch which (roughly) adds a higher priority class. It's not deterministic in any way.

There are at last count three separate sets of patches that add real time support to the Linux kernel. I'm interested to find out which they used or if they wrote their own.

True hard real time is great, but not actually necessary for a lot of automation applications.
