TLM extensions - status

All,

Combining the votes related to Jerome's TLM changes, I have seen

YES - Jerome, Stuart, Bisnupriya, Mac, Philipp
NO  - Bart, John

How about we add a new attribute to the generic payload

* Default value 0 => old initiator
* Value 1 => (set by initiator) new initiator, byte enable/width/response fields are properly set for DMI/Debug
* Value 2 => (set by target) new initiator & new target, target has properly set response status

(There will need to be a new TLM-2.0.2 kit, so existing code will need to be recompiled anyway.)

That would resolve all my backward compatibility concerns (because a new target would know it had a transaction from a new initiator) and would go futher in that it would allow a new initiator to rely on the full range of response status values.

Would that work for everyone, or am I just stirring mud?

Thanks

John A
