== Summary ==

This specification details the plan to add hard real time support in Ubuntu.

== Rationale ==

In some contexts (i.e. industrial automation, robotics and telco) the low-latency support is insufficient. In order to push Ubuntu in these contexts is necessary the support for high resolution timers and the full preemption in the Linux kernel. These features have been implemented by Thomas Gleixner and Ingo Molnar (http://people.redhat.com/mingo/realtime-preempt/).

We want also a valid FLOSS alternative to SLERT (http://www.novell.com/products/realtime/).

== Use cases ==

Alex is developing an application software (SCADA type) for a customer and he would be very happy to use Linux and Ubuntu for the deployment.

== Scope ==

This specification cover the linux kernel in Ubuntu.

== Design ==

== Implementation ==

We hope to add a linux-image-realtime package in universe repositary (the same place of the linux-image-lowlatency package).

=== Code ===

=== Data preservation and migration ===

== Unresolved issues ==

== BoF agenda and discussion ==
