Quoting Tvrtko Ursulin (2017-09-18 12:38:06)
From: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxx>
Fourth spin of the i915 PMU series. Now with the RFC tag removed.
Just to dump one idea that I wanted to report in the overlay: rate of
object allocation, deallocation; pages pinned, unpinned; vma bind, unbind.
They tend to be the other things I find of interest in reading traces.
If getting these rates via tracepoints like today is not good enough we
could add that at a later point.
Now the problem with vma is that it would be nice if it were tied to a
context/process. Pid filtering might be interesting...
And in fact there are already feature requests from customers to provide
engine busyness per context, with per pid probably being good enough.
This as well I said we are going to leave for the 2nd stage.
I am hoping you are not proposing to cram everything from the above into v1?
Regards,
Tvrtko
