Dear colleagues,
Q23/17 on time and performance made a very fruitful meeting in Erlangen on
20-21 November;
We are now about to present a coherent proposal for "SDL for real time". But
where to put it ?
Most of the proposals for SDL are really to be considered for core SDL :
"generalized timer type", generalized "clock type", "urgencies" and even a
new scheduling mechanism
(choice of transition to be triggered) that takes urgencies in account for
real time
(nevertheless compatible with the "old fashion" scheduler : real time
extensions will be
transparent for those who do not need it) A new SDL construct will be
proposed for each
of these concepts.
Other extensions are not realy core SDL, and could just be implemented as
annotations (task delays or channel delays or channel reliability).
Finally, a third set of extensions (assumptions, performance requirements,
resources)are realy not core SDL.
Our question is : what are the rules (if any) to put something rather as an
extension to Z100 than in a separate recommandation?
Does it become mandatory ?
