So personally you don't think it should be of any concern if a GGTT
VMA is at the head of the list, but it is not the same GGTT VMA
which you would find there in majority of cases?

Actually, regarding error capture it is sorting of the vm list that is
important - so a different list.

I am still confused about why having different GGTT views makes it
difficult putting the normal GGTT vm first. I would very much like the
standard GGTT view remain first, and I would actually like the MRU
ppgtt last (so that the two most common uses are easily found).

It is not difficult, but it is not guaranteed that, when there is a single GGTT vma on the list, it is a normal one.

+ Daniel since this is at least how I interpreted our discussion about this. Maybe I got it wrong, who knows.

Tvrtko
