Re: [linuxtools-dev] pinning TMF derived views to a given trace?

[Marc Khouzam <marc.khouzam@xxxxxxxxxxxx>]

Hi,

I'm not sure if this is relevant but I thought I'd mention it.
There is a Pin&Clone feature proposed for Platform Debug.
The bug is old, but there is a big push for it now and
it may make it into Kepler.
https://bugs.eclipse.org/bugs/show_bug.cgi?id=145635

Maybe the mechanism can be re-used for other views.

Just a thought.
